Revision 13 1-1

1 – ProASIC3L Device Family Overview

General Description

The ProASIC3L family of Microsemi flash FPGAs dramatically reduces dynamic power consumption by

40% and static power by 50% compared to the equivalent ProASIC3 device. These power savings are

coupled with performance, density, true single-chip, 1.2 V to 1.5 V core and I/O operation as low as

1.2 V, reprogrammability, and advanced features.

Using Microsemi's proven Flash*Freeze technology enables users to shut off dynamic power

instantaneously and switch the device to static mode without the need to switch off clocks or power

supplies while retaining internal states of the device. This greatly simplifies power management on a

board done through I/Os and clocks. In addition, optimized software tools using power-driven layout

provide instant push-button power reduction.

Nonvolatile flash technology gives ProASIC3L devices the advantage of being a secure, low-power,

single-chip solution that is Instant On. ProASIC3L offers dramatic dynamic power savings giving the

FPGA users flexibility to combine low power with high performance.

These features enable designers to create high-density systems using existing ASIC or FPGA design

flows and tools.

ProASIC3L devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as

clock conditioning circuitry (CCC) based on an integrated phase-locked loop (PLL). ProASIC3L devices

support devices from 250 k system gates to 3 million system gates with up to 504 kbits of true dual-port

SRAM and 620 user I/Os.

M1 ProASIC3L devices support the high-performance, 32-bit Cortex-M1 processor developed by ARM

for implementation in FPGAs. ARM Cortex-M1 is a soft processor that is fully implemented in the FPGA

fabric. It has a three-stage pipeline that offers a good balance between low-power consumption and

speed when implemented in an M1 ProASIC3L device. The processor runs the ARMv6-M instruction set,

has a configurable nested interrupt controller, and can be implemented with or without the debug block.

ARM Cortex-M1 is available for free from Microsemi for use in M1 ProASIC3L FPGAs.

The ARM-enabled devices have Microsemi SoC Products Group ordering numbers that begin with M1

and do not support AES decryption.

Flash*Freeze Technology

The ProASIC3L devices offer Microsemi's proven Flash*Freeze technology, which allows instantaneous

switching from an active state to a static state. ProASIC3L devices do not need additional components to

turn off I/Os or clocks while retaining the design information, SRAM content, and registers. Flash*Freeze

technology is combined with in-system programmability, which enables users to quickly and easily

upgrade and update their designs in the final stages of manufacturing or in the field. The ability of

ProASIC3L devices to support a wide range core voltage (1.2 V to 1.5 V) allows for an even greater

reduction in power consumption, which enables low total system power.

When the ProASIC3L device enters Flash*Freeze mode, the device automatically shuts off the clocks

and inputs to the FPGA core; when the device exits Flash*Freeze mode, all activity resumes and data is

retained.

The availability of low-power modes, combined with a reprogrammable, single-chip, single-voltage

solution, make ProASIC3L devices suitable for low-power data transfer and manipulation in portable

media, secure communications, radio applications as well as high performance portable, industrial, test,

scientific, and medical applications.

ProASIC3L Device Family Overview

Flash Advantages

Low Power

The ProASIC3L family of Microsemi flash-based FPGAs provide a low-power advantage, and when

coupled with high performance, enables designers to make power-smart choices using a single-chip,

reprogrammable, and Instant On device.

ProASIC3L devices offer 40% dynamic power and 50% static power savings compared to the equivalent

ProASIC3 device by reducing the core operating voltage to 1.2 V. In addition, the Power Driven Layout

(PDL) feature in Libero® System-on-Chip (SoC) offers up to 30% additional power reduction over the

standard timing-driven place-and-route (TDPR). With Flash*Freeze technology, ProASIC3L devices are

able to retain device SRAM and logic while dynamic power is reduced to a minimum, without the need to

stop clock or power supplies. Combining these features provides a low-power, feature-rich and high-

performance solution.

Security

Nonvolatile, flash-based ProASIC3L devices do not require a boot PROM, so there is no vulnerable

external bitstream that can be easily copied. ProASIC3L devices incorporate FlashLock, which provides

a unique combination of reprogrammability and design security without external overhead, advantages

that only an FPGA with nonvolatile flash programming can offer.

ProASIC3L devices utilize a 128-bit flash-based lock and a separate AES key to provide the highest level

of protection in the FPGA industry for programmed intellectual property and configuration data. In

addition, all FlashROM data in ProASIC3L devices can be encrypted prior to loading, using the industry-

leading AES-128 (FIPS192) bit block cipher encryption standard. AES was adopted by the National

Institute of Standards and Technology (NIST) in 2000 and replaces the 1977 DES standard. ProASIC3L

devices have a built-in AES decryption engine and a flash-based AES key that make them the most

comprehensive programmable logic device security solution available today. ProASIC3L devices with

AES-based security provide a high level of protection for remote field updates over public networks such

as the Internet, and are designed to ensure that valuable IP remains out of the hands of system

overbuilders, system cloners, and IP thieves.

Security, built into the FPGA fabric, is an inherent component of the ProASIC3L family. The flash cells

are located beneath seven metal layers, and many device design and layout techniques have been used

to make invasive attacks extremely difficult. The ProASIC3L family, with FlashLock and AES security, is

unique in being highly resistant to both invasive and noninvasive attacks. Your valuable IP is protected

with industry-standard security, making remote ISP possible. A ProASIC3L device provides the best

available security for programmable logic designs.

Single Chip

Flash-based FPGAs store their configuration information in on-chip flash cells. Once programmed, the

configuration data is an inherent part of the FPGA structure, and no external configuration data needs to

be loaded at system power-up (unlike SRAM-based FPGAs). Therefore, flash-based ProASIC3L FPGAs

do not require system configuration components such as EEPROMs or microcontrollers to load device

configuration data. This reduces bill-of-materials costs and PCB area, and increases security and system

reliability.

Instant On

Flash-based ProASIC3L devices support Level 0 of the Instant On classification standard. This feature

helps in system component initialization, execution of critical tasks before the processor wakes up, setup

and configuration of memory blocks, clock generation, and bus activity management. The Instant On

feature of flash-based ProASIC3L devices greatly simplifies total system design and reduces total

system cost, often eliminating the need for CPLDs and clock generation PLLs. In addition, glitches and

brownouts in system power will not corrupt the ProASIC3L device's flash configuration, and unlike

SRAM-based FPGAs, the device will not have to be reloaded when system power is restored. This

enables the reduction or complete removal of the configuration PROM, expensive voltage monitor,

brownout detection, and clock generator devices from the PCB design. Flash-based ProASIC3L devices

simplify total system design and reduce cost and design risk while increasing system reliability and

improving system initialization time.

ProASIC3L Low Power Flash FPGAs

Revision 13 1-3

Reduced Cost of Ownership

Advantages to the designer extend beyond low unit cost, performance, and ease of use. Unlike SRAM-

based FPGAs, flash-based ProASIC3L devices allow all functionality to be Instant On; no external boot

PROM is required. On-board security mechanisms prevent access to all the programming information

and enable secure remote updates of the FPGA logic. Designers can perform secure remote in-system

reprogramming to support future design iterations and field upgrades with confidence that valuable

intellectual property cannot be compromised or copied. Secure ISP can be performed using the industry-

standard AES algorithm. The ProASIC3L family device architecture mitigates the need for ASIC

migration at higher user volumes. This makes the ProASIC3L family a cost-effective ASIC replacement

solution, manipulation in portable media and secure communications, radio applications as well as high

performance portable Industrial, test, scientific and medical applications.

Firm-Error Immunity

Firm errors occur most commonly when high-energy neutrons, generated in the upper atmosphere, strike

a configuration cell of an SRAM FPGA. The energy of the collision can change the state of the

configuration cell and thus change the logic, routing, or I/O behavior in an unpredictable way. These

errors are impossible to prevent in SRAM FPGAs. The consequence of this type of error can be a

complete system failure. Firm errors do not exist in the configuration memory of ProASIC3L flash-based

FPGAs. Once it is programmed, the flash cell configuration element of ProASIC3L FPGAs cannot be

altered by high-energy neutrons and is therefore immune to them. Recoverable (or soft) errors occur in

the user data SRAM of all FPGA devices. These can easily be mitigated by using error detection and

correction (EDAC) circuitry built into the FPGA fabric.

Advanced Flash Technology

The ProASIC3L family offers many benefits, including nonvolatility and reprogrammability, through an

advanced flash-based, 130-nm LVCMOS process with 7 layers of metal. Standard CMOS design

techniques are used to implement logic and control functions. The combination of fine granularity,

enhanced flexible routing resources, and abundant flash switches allows for very high logic utilization

without compromising device routability or performance. Logic functions within the device are

interconnected through a four-level routing hierarchy.

Advanced Architecture

The proprietary ProASIC3L architecture provides granularity comparable to standard-cell ASICs. The

ProASIC3L device consists of five distinct and programmable architectural features (Figure 1-1 on

page 1-4 and Figure 1-2 on page 1-4):

• FPGA VersaTiles

• Dedicated FlashROM

• Dedicated SRAM/FIFO memory

• Extensive CCCs and PLLs

• I/O structure

The FPGA core consists of a sea of VersaTiles. Each VersaTile can be configured as a three-input logic

function, a D-flip-flop (with or without enable), or a latch by programming the appropriate flash switch

interconnections. The versatility of the ProASIC3L core tile, as either a three-input lookup table (LUT)

equivalent or a D-flip-flop/latch with enable, allows for efficient use of the FPGA fabric.

The VersaTile capability is unique to the ProASIC family of third-generation-architecture flash FPGAs.

VersaTiles are connected with any of the four levels of routing hierarchy. Flash switches are distributed

throughout the device to provide nonvolatile, reconfigurable interconnect programming. Maximum core

utilization is possible for virtually any design.

ProASIC3L Low Power Flash FPGAs

Revision 13 1-5

Flash*Freeze Technology

The ProASIC3L devices offer Microsemi's proven Flash*Freeze technology, which enables designers to

instantaneously shut off dynamic power consumption while retaining all SRAM and register information.

Flash*Freeze technology enables the user to quickly (within 1 µs) enter and exit Flash*Freeze mode by

activating the Flash*Freeze (FF) pin while all power supplies are kept at their original values. In addition,

I/Os and global I/Os can still be driven and can be toggling without impact on power consumption; clocks

can still be driven or can be toggling without impact on power consumption; and the device retains all

core registers, SRAM information, and states. I/O states are tristated during Flash*Freeze mode or can

be set to a certain state using weak pull-up or pull-down I/O attribute configuration. No power is

consumed by the I/O banks, clocks, JTAG pins, or PLL. Flash*Freeze technology allows the user to

switch to active mode on demand, thus simplifying the power management of the device.

The FF pin (active low) can be routed internally to the core to allow the user's logic to decide when it is

safe to transition to this mode. It is also possible to use the FF pin as a regular I/O if Flash*Freeze mode

usage is not planned, which is advantageous because of the inherent low-power static and dynamic

capabilities of the ProASIC3L device. Refer to Figure 1-3 for an illustration of entering/exiting

Flash*Freeze mode.

VersaTiles

The ProASIC3L core consists of VersaTiles, which have been enhanced beyond the ProASICPLUS® core

tiles. The ProASIC3L VersaTile supports the following:

• All 3-input logic functions—LUT-3 equivalent

• Latch with clear or set

• D-flip-flop with clear or set

• Enable D-flip-flop with clear or set

Refer to Figure 1-4 for VersaTile configurations.

ProASIC3L Device Family Overview

1-6 Revision 13

User Nonvolatile FlashROM

ProASIC3L devices have 1 kbit of on-chip, user-accessible, nonvolatile FlashROM. The FlashROM can

be used in diverse system applications:

• Internet Protocol addressing (wireless or fixed)

• System calibration settings

• Device serialization and/or inventory control

• Subscription-based business models (for example, set-top boxes)

• Secure key storage for secure communications algorithms

• Asset management/tracking

• Date stamping

• Version management

The FlashROM is written using the standard ProASIC3L IEEE 1532 JTAG programming interface.The

core can be individually programmed (erased and written), and on-chip AES decryption can be used

selectively to securely load data over public networks, as in security keys stored in the FlashROM for a

user design.

The FlashROM can be programmed via the JTAG programming interface, and its contents can be read

back either through the JTAG programming interface or via direct FPGA core addressing. Note that the

FlashROM can only be programmed from the JTAG interface and cannot be programmed from the

internal logic array.

The FlashROM is programmed as 8 banks of 128 bits; however, reading is performed on a byte-by-byte

basis using a synchronous interface. A 7-bit address from the FPGA core defines which of the 8 banks

and which of the 16 bytes within that bank are being read. The three most significant bits (MSBs) of the

FlashROM address determine the bank, and the four least significant bits (LSBs) of the FlashROM

address define the byte.

The ProASIC3L development software solutions, Libero SoC and Designer, have extensive support for

the FlashROM. One such feature is auto-generation of sequential programming files for applications

requiring a unique serial number in each part. Another feature allows the inclusion of static data for

system version control. Data for the FlashROM can be generated quickly and easily using Libero SoC

and Designer software tools. Comprehensive programming file support is also included to allow for easy

programming of large numbers of parts with differing FlashROM contents.

SRAM and FIFO

ProASIC3L devices have embedded SRAM blocks along their north and south sides. Each variable-

aspect-ratio SRAM block is 4,608 bits in size. Available memory configurations are 256×18, 512×9,

1k×4, 2k×2, and 4k×1 bits. The individual blocks have independent read and write ports that can be

configured with different bit widths on each port. For example, data can be sent through a 4-bit port and

read as a single bitstream. The embedded SRAM blocks can be initialized via the device JTAG port

(ROM emulation mode) using the UJTAG macro.

In addition, every SRAM block has an embedded FIFO control unit. The control unit allows the SRAM

block to be configured as a synchronous FIFO without using additional core VersaTiles. The FIFO width

and depth are programmable. The FIFO also features programmable Almost Empty (AEMPTY) and

Almost Full (AFULL) flags in addition to the normal Empty and Full flags. The embedded FIFO control

unit contains the counters necessary for generation of the read and write address pointers. The

embedded SRAM/FIFO blocks can be cascaded to create larger configurations.

PLL and CCC

ProASIC3L devices provide designers with flexible clock conditioning circuit (CCC) capabilities. Each

member of the ProASIC3L family contains six CCCs. One CCC (center west side) has a PLL.

The six CCC blocks are located at the four corners and the centers of the east and west sides. One CCC

(center west side) has a PLL.

All six CCC blocks are usable; the four corner CCCs and the east CCC allow simple clock delay

operations as well as clock spine access.

The inputs of the six CCC blocks are accessible from the FPGA core or from one of several inputs

located near the CCC that have dedicated connections to the CCC block.

ProASIC3L Low Power Flash FPGAs

Revision 13 1-7

The CCC block has these key features:

• Wide input frequency range (fIN_CCC) = 1.5 MHz up to 250 MHz

• Output frequency range (fOUT_CCC) = 0.75 MHz up to 250 MHz

• 2 programmable delay types for clock skew minimization

• Clock frequency synthesis

Additional CCC specifications:

• Internal phase shift = 0°, 90°, 180°, and 270°. Output phase shift depends on the output divider

configuration.

• Output duty cycle = 50% ± 1.5% or better

• Low output jitter: worst case < 2.5% × clock period peak-to-peak period jitter when single global

network used

• Maximum acquisition time is 300 µs

• Exceptional tolerance to input period jitter— allowable input jitter is up to 1.5 ns

• Four precise phases; maximum misalignment between adjacent phases of 40 ps × 250 MHz /

fOUT_CCC

Global Clocking

ProASIC3L devices have extensive support for multiple clocking domains. In addition to the CCC and

PLL support described above, there is a comprehensive global clock distribution network.

Each VersaTile input and output port has access to nine VersaNets: six chip (main) and three quadrant

global networks. The VersaNets can be driven by the CCC or directly accessed from the core via

multiplexers (MUXes). The VersaNets can be used to distribute low-skew clock signals or for rapid

distribution of high-fanout nets.

I/Os with Advanced I/O Standards

The ProASIC3L family of FPGAs features a flexible I/O structure, supporting a range of voltages (1.2 V,

1.5 V, 1.8 V, 2.5 V, 3.0 V wide range, and 3.3 V). ProASIC3L FPGAs support different I/O standards,

including single-ended, differential, and voltage-referenced (ProASIC3EL only). The I/Os are organized

into banks, with two, four, or eight (ProASIC3EL only) banks per device. The configuration of these banks

determines the I/O standards supported (Ta ble 1 -1 ). For ProASIC3EL, each I/O bank is subdivided into

VREF minibanks, which are used by voltage-referenced I/Os. VREF minibanks contain 8 to 18 I/Os. All

the I/Os in a given minibank share a common VREF line. Therefore, if any I/O in a given VREF minibank

is configured as a VREF pin, the remaining I/Os in that minibank will be able to use that reference

voltage.

Each I/O module contains several input, output, and enable registers. These registers allow the

implementation of the following:

• Single-data-rate applications (e.g., PCI 66 MHz, bidirectional SSTL 2 and 3, Class I and II)

• Double-data-Rate applications (e.g., DDR LVDS, B-LVDS, and M-LVDS I/Os for point-to-point

communications, and DDR 200 MHz SRAM using bidirectional HSTL Class II).

ProASIC3L banks support LVPECL, LVDS, B-LVDS, and M-LVDS. B-LVDS and M-LVDS can support up

to 20 loads.

Hot-swap (also called hot-plug, or hot-insertion) is the operation of hot-insertion or hot-removal of a card

in a powered-up system.

Cold-sparing (also called cold-swap) refers to the ability of a device to leave system data undisturbed

when the system is powered up, while the component itself is powered down, or when power supplies

are floating.

Wide Range I/O Support

ProASIC3L devices support JEDEC-defined wide range I/O operation. ProASIC3L devices support both

the JESD8-B specification, covering 3 V and 3.3 V supplies, for an effective operating range of 2.7 V to

3.6 V, and JESD8-12 with its 1.2 V nominal, supporting an effective operating range of 1.14 V to 1.575 V.

Wider I/O range means designers can eliminate power supplies or power conditioning components from

the board or move to less costly components with greater tolerances. Wide range eases I/O bank

management and provides enhanced protection from system voltage spikes, while providing the flexibility

to easily run custom voltage applications.

Specifying I/O States During Programming

You can modify the I/O states during programming in FlashPro. In FlashPro, this feature is supported for

PDB files generated from Designer v8.5 or greater. See the FlashPro User’s Guide for more information.

Note: PDB files generated from Designer v8.1 to Designer v8.4 (including all service packs) have

limited display of Pin Numbers only.

1. Load a PDB from the FlashPro GUI. You must have a PDB loaded to modify the I/O states during

programming.

2. From the FlashPro GUI, click PDB Configuration. A FlashPoint – Programming File Generator

window appears.

3. Click the Specify I/O States During Programming button to display the Specify I/O States

During Programming dialog box.

4. Sort the pins as desired by clicking any of the column headers to sort the entries by that header.

Select the I/Os you wish to modify (Figure 1-5 on page 1-9).

5. Set the I/O Output State. You can set Basic I/O settings if you want to use the default I/O settings

for your pins, or use Custom I/O settings to customize the settings for each pin. Basic I/O state

settings:

1 – I/O is set to drive out logic High

0 – I/O is set to drive out logic Low

Last Known State – I/O is set to the last value that was driven out prior to entering the

programming mode, and then held at that value during programming

Z -Tri-State: I/O is tristated

6. Click OK to return to the FlashPoint – Programming File Generator window.

Note: I/O States during programming are saved to the ADB and resulting programming files after

completing programming file generation.

I/O Power-Up and Supply Voltage Thresholds for Power-On Reset

(Commercial and Industrial)

Sophisticated power-up management circuitry is designed into every ProASIC3 device. These circuits

ensure easy transition from the powered-off state to the powered-up state of the device. The many

different supplies can power up in any sequence with minimized current spikes or surges. In addition, the

I/O will be in a known state through the power-up sequence. The basic principle is shown in Figure 2-1

on page 2-4 and Figure 2-2 on page 2-5.

There are five regions to consider during power-up.

ProASIC3 I/Os are activated only if ALL of the following three conditions are met:

1. VCC and VCCI are above the minimum specified trip points (Figure 2-1 on page 2-4 and

Figure 2-2 on page 2-5).

2. VCCI > VCC – 0.75 V (typical)

3. Chip is in the operating mode.

VCCI Trip Point:

Ramping up: 0.6 V < trip_point_up < 1.2 V

Ramping down: 0.5 V < trip_point_down < 1.1 V

VCC Trip Point:

Ramping up: 0.6 V < trip_point_up < 1.1 V

Ramping down: 0.5 V < trip_point_down < 1 V

VCC and VCCI ramp-up trip points are about 100 mV higher than ramp-down trip points. This specifically

built-in hysteresis prevents undesirable power-up oscillations and current surges. Note the following:

• During programming, I/Os become tristated and weakly pulled up to VCCI.

• JTAG supply, PLL power supplies, and charge pump VPUMP supply have no influence on I/O

behavior.

2. The duration is allowed at one out of six clock cycles. If the overshoot/undershoot occurs at one out of

two cycles, the maximum overshoot/undershoot has to be reduced by 0.15 V.

3. This table does not provide PCI overshoot/undershoot limits.

PLL Behavior at Brownout Condition

Microsemi recommends using monotonic power supplies or voltage regulators to ensure proper powerup

behavior. Power ramp-up should be monotonic at least until VCC and VCCPLX exceed brownout

activation levels. The VCC activation level is specified as 1.1 V worst-case (see Figure 2-1 and Figure 2-

2 on page 2-5 for more details).

When PLL power supply voltage and/or VCC levels drop below the VCC brownout levels (0.75 V ± 0.25

V), the PLL output lock signal goes low and/or the output clock is lost. Refer to the "Power-Up/-Down

Behavior of Low-Power Flash Devices" chapter of the ProASIC3L FPGA Fabric User’s Guide for

information on clock and lock recovery.

Thermal Characteristics

Introduction

The temperature variable in the Designer software refers to the junction temperature, not the ambient

temperature. This is an important distinction because dynamic and static power consumption cause the

chip junction temperature to be higher than the ambient temperature.

EQ 1 can be used to calculate junction temperature.

TJ = Junction Temperature = T + TA

EQ 1

where:

TA = Ambient Temperature

T = Temperature gradient between junction (silicon) and ambient T = ja * P

ja = Junction-to-ambient of the package. ja numbers are located in Table 2-5.

P = Power dissipation

Package Thermal Characteristics

The device junction-to-case thermal resistivity is jc and the junction-to-ambient air thermal resistivity is

ja. The thermal characteristics for ja are shown for two air flow rates. The absolute maximum junction

temperature is 100°C. EQ 2 shows a sample calculation of the absolute maximum power dissipation

Temperature and Voltage Derating Factors

Calculating Power Dissipation

Quiescent Supply Current

Quiescent supply current (IDD) calculation depends on multiple factors, including operating voltages

(VCC, VCCI, and VJTAG), operating temperature, system clock frequency, and power mode usage.

Microsemi recommends using the Power Calculator and SmartPower software estimation tools to

evaluate the projected static and active power based on the user design, power mode usage, operating

voltage, and temperature.

Guidelines

Toggle Rate Definition

A toggle rate defines the frequency of a net or logic element relative to a clock. It is a percentage. If the

toggle rate of a net is 100%, this means that this net switches at half the clock frequency. Below are

some examples:

• The average toggle rate of a shift register is 100% because all flip-flop outputs toggle at half of the

clock frequency.

• The average toggle rate of an 8-bit counter is 25%:

– Bit 0 (LSB) = 100%

– Bit 1 = 50%

– Bit 2 = 25%

–…

– Bit 7 (MSB) = 0.78125%

– Average toggle rate = (100% + 50% + 25% + 12.5% + . . . + 0.78125%) / 8

Enable Rate Definition

Output enable rate is the average percentage of time during which tristate outputs are enabled. When

nontristate output buffers are used, the enable rate should be 100%.

Notes:

1. The minimum drive strength for any LVCMOS 1.2 V or LVCMOS 3.3 V software configuration when run in wide range is

±100 µA. Drive strength displayed in the software is supported for normal range only. For a detailed I/V curve, refer to the

IBIS models.

2. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD8-B specification.

3. Resistance is used to measure I/O propagation delays as defined in PCI specifications. See Figure 2-12 on page 2-81 for

connectivity. This resistor is not required during normal operation.

4. For specific junction temperature and voltage supply levels, refer to Table 2-6 on page 2-7 for derating values.

5. Output drive strength is below JEDEC specification.

The length of time an I/O can withstand IOSH/IOSL events depends on the junction temperature. The

reliability data below is based on a 3.3 V, 12 mA I/O setting, which is the worst case for this type of

analysis.

For example, at 100°C, the short current condition would have to be sustained for more than six months

to cause a reliability concern. The I/O design does not contain any short circuit protection, but such

protection would only be needed in extremely prolonged stress conditions.

Note: *The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the noise is low,

then the rise time and fall time of input buffers can be increased beyond the maximum value. The longer the

rise/fall times, the more susceptible the input signal is to the board noise. Microsemi recommends signal

integrity evaluation/characterization of the system to ensure that there is no excessive noise coupling into input

signals.
