1 – ProASIC3 Device Family Overview

General Description

ProASIC3, the third-generation family of Actel flash FPGAs, offers performance, density, and

features beyond those of the ProASICPLUS® family. Nonvolatile flash technology gives ProASIC3

devices the advantage of being a secure, low-power, single-chip solution that is live at power-up

(LAPU). ProASIC3 is reprogrammable and offers time-to-market benefits at an ASIC-level unit cost.

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

flows and tools.

ProASIC3 devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as

clock conditioning circuitry based on an integrated phase-locked loop (PLL). The A3P015 and

A3P030 devices have no PLL or RAM support. ProASIC3 devices have up to 1 million system gates,

supported with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os.

ProASIC3 devices support the ARM Cortex-M1 processor. The ARM-enabled devices have Actel

ordering numbers that begin with M1A3P (Cortex-M1) and do not support AES decryption.

Flash Advantages

Reduced Cost of Ownership

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

SRAM-based FPGAs, flash-based ProASIC3 devices allow all functionality to be live at power-up; 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 (IP) cannot be compromised or

copied. Secure ISP can be performed using the industry-standard AES algorithm. The ProASIC3

family device architecture mitigates the need for ASIC migration at higher user volumes. This

makes the ProASIC3 family a cost-effective ASIC replacement solution, especially for applications in

the consumer, networking/ communications, computing, and avionics markets.

Security

The nonvolatile, flash-based ProASIC3 devices do not require a boot PROM, so there is no

vulnerable external bitstream that can be easily copied. ProASIC3 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.

ProASIC3 devices utilize a 128-bit flash-based lock and a separate AES key to secure programmed

intellectual property and configuration data. In addition, all FlashROM data in ProASIC3 devices

can be encrypted prior to loading, using the industry-leading AES-128 (FIPS192) bit block cipher

encryption standard. The AES standard was adopted by the National Institute of Standards and

Technology (NIST) in 2000 and replaces the 1977 DES standard. ProASIC3 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. ProASIC3 devices with AES-based

security allow for secure, remote field updates over public networks such as the Internet, and

ensure that valuable IP remains out of the hands of system overbuilders, system cloners, and IP

thieves. The contents of a programmed ProASIC3 device cannot be read back, although secure

design verification is possible.

ARM-enabled ProASIC3 devices do not support user-controlled AES security mechanisms. Since the

ARM core must be protected at all times, AES encryption is always on for the core logic, so

bitstreams are always encrypted. There is no user access to encryption for the FlashROM

programming data.

ProASIC3 Device Family Overview

1-2 v1.3

Security, built into the FPGA fabric, is an inherent component of the ProASIC3 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 ProASIC3 family, with FlashLock and AES

security, is unique in being highly resistant to both invasive and noninvasive attacks. Your valuable

IP is protected and secure, making remote ISP possible. A ProASIC3 device provides the most

impenetrable 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

ProASIC3 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.

Live at Power-Up

The Actel flash-based ProASIC3 devices support Level 0 of the LAPU 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 LAPU feature of flash-based ProASIC3 devices greatly simplifies total system

design and reduces total system cost, often eliminating the need for CPLDs and clock generation

PLLs that are used for these purposes in a system. In addition, glitches and brownouts in system

power will not corrupt the ProASIC3 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 ProASIC3 devices simplify total

system design and reduce cost and design risk while increasing system reliability and improving

system initialization time.

Firm Errors

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 ProASIC3 flash-

based FPGAs. Once it is programmed, the flash cell configuration element of ProASIC3 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.

Low Power

Flash-based ProASIC3 devices exhibit power characteristics similar to an ASIC, making them an ideal

choice for power-sensitive applications. ProASIC3 devices have only a very limited power-on current

surge and no high-current transition period, both of which occur on many FPGAs.

ProASIC3 devices also have low dynamic power consumption to further maximize power savings.

ProASIC3 Device Family Overview

v1.3 1-3

Advanced Flash Technology

The ProASIC3 family offers many benefits, including nonvolatility and reprogrammability through

an advanced flash-based, 130-nm LVCMOS process with seven 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 ProASIC3 architecture provides granularity comparable to standard-cell ASICs. The

ProASIC3 device consists of five distinct and programmable architectural features (Figure 1-1 and

Figure 1-2 on page 1-4):

• FPGA VersaTiles

• Dedicated FlashROM

• Dedicated SRAM/FIFO memory†

• Extensive CCCs and PLLs†

• Advanced I/O structure

† The A3P015 and A3P030 do not support PLL or SRAM.

ProASIC3 Device Family Overview

1-4 v1.3

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 ProASIC3 core tile as either a three-input

lookup table (LUT) equivalent or as a D-flip-flop/latch with enable allows for efficient use of the

FPGA fabric. The VersaTile capability is unique to the Actel 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.

In addition, extensive on-chip programming circuitry allows for rapid, single-voltage (3.3 V)

programming of ProASIC3 devices via an IEEE 1532 JTAG interface.

VersaTiles

The ProASIC3 core consists of VersaTiles, which have been enhanced beyond the ProASICPLUS® core

tiles. The ProASIC3 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

User Nonvolatile FlashROM

Actel ProASIC3 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 ProASIC3 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 (except in the A3P015 and A3P030 devices),

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 Actel ProASIC3 development software solutions, Libero® Integrated Design Environment (IDE)

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 Actel Libero IDE 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

ProASIC3 devices (except the A3P015 and A3P030 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 (except in A3P015 and A3P030 devices).

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

ProASIC3 devices provide designers with very flexible clock conditioning capabilities. Each member

of the ProASIC3 family contains six CCCs. One CCC (center west side) has a PLL. The A3P015 and

A3P030 devices do not have a PLL.

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

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.

The CCC block has these key features:

• Wide input frequency range (fIN_CCC) = 1.5 MHz to 350 MHz

• Output frequency range (fOUT_CCC) = 0.75 MHz to 350 MHz

• Clock delay adjustment via programmable and fixed delays from –7.56 ns to +11.12 ns

• 2 programmable delay types for clock skew minimization

• Clock frequency synthesis (for PLL only)

Additional CCC specifications:

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

divider configuration (for PLL only).

• Output duty cycle = 50% ± 1.5% or better (for PLL only)

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

global network used (for PLL only)

• Maximum acquisition time = 300 µs (for PLL only)

• Low power consumption of 5 mW

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

only)

• Four precise phases; maximum misalignment between adjacent phases of 40 ps × (350 MHz /

fOUT_CCC) (for PLL only)

Global Clocking

ProASIC3 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.

v1.3 1-7

I/Os with Advanced I/O Standards

The ProASIC3 family of FPGAs features a flexible I/O structure, supporting a range of voltages

(1.5 V, 1.8 V, 2.5 V, and 3.3 V). ProASIC3 FPGAs support many different I/O standards—single-ended

and differential.

The I/Os are organized into banks, with two or four banks per device. The configuration of these

banks determines the I/O standards supported (Table 1-1).

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

implementation of the following:

• Single-Data-Rate applications

• Double-Data-Rate applications—DDR LVDS, B-LVDS, and M-LVDS I/Os for point-to-point

communications

ProASIC3 banks for the A3P250 device and above 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

Actel ProASIC3 devices support JEDEC-defined wide range I/O operation. ProASIC3 supports the

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

2.7 V to 3.6 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.

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

(Commercial and Industrial)

Sophisticated power-up management circuitry is designed into every ProASIC®3 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.

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).

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.

PLL Behavior at Brownout Condition

Actel recommends using monotonic power supplies or voltage regulators to ensure proper power-

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

activation levels. The VCC activation level is specified as 1.1 V worst-case (see Figure 2-1 on page 2-4

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

Table 2-4 • Overshoot and Undershoot Limits 1

Notes:

1. Based on reliability requirements at 85°C.

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.

Thermal Characteristics

Introduction

The temperature variable in the Actel 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 to be higher than the ambient temperature.

EQ 2-1 can be used to calculate junction temperature.

TJ = Junction Temperature = ΔT + TA

EQ 2-1

where:

TA = Ambient Temperature

ΔT = Temperature gradient between junction (silicon) and ambient ΔT = θja * P

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

P = Power dissipation

Package Thermal Characteristics

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

resistivity is θja. The thermal characteristics for θja are shown for two air flow rates. The absolute

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

maximum power dissipation allowed for a 484-pin FBGA package at commercial temperature and

in still air.

Power Calculation Methodology

This section describes a simplified method to estimate power consumption of an application. For

more accurate and detailed power estimations, use the SmartPower tool in Actel Libero IDE

software.

The power calculation methodology described below uses the following variables:

• The number of PLLs as well as the number and the frequency of each output clock

generated

• The number of combinatorial and sequential cells used in the design

•The internal clock frequencies

• The number and the standard of I/O pins used in the design

• The number of RAM blocks used in the design

• Toggle rates of I/O pins as well as VersaTiles—guidelines are provided in Table 2-16 on

page 2-13.

• Enable rates of output buffers—guidelines are provided for typical applications in

Table 2-17 on page 2-13.

• Read rate and write rate to the memory—guidelines are provided for typical applications in

Table 2-17 on page 2-13. The calculation should be repeated for each clock domain defined

in the design.

1. The PLL dynamic contribution depends on the input clock frequency, the number of output clock signals generated

by the PLL, and the frequency of each output clock. If a PLL is used to generate more than one output clock, include

each output clock in the formula by adding its corresponding contribution (PAC14 * FCLKOUT product) to the total PLL

contribution.

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%.

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 110°C, the short current condition would have to be sustained for more than three

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.

*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. Actel recommends signal integrity evaluation/characterization of the system to

ensure that there is no excessive noise coupling into input signals.

v1.4 2-67

Differential I/O Characteristics

Physical Implementation

Configuration of the I/O modules as a differential pair is handled by Actel Designer software when

the user instantiates a differential I/O macro in the design.

Differential I/Os can also be used in conjunction with the embedded Input Register (InReg), Output

support for bidirectional I/Os or tristates with the LVPECL standards.

LVDS

Low-Voltage Differential Signaling (ANSI/TIA/EIA-644) is a high-speed, differential I/O standard. It

requires that one data bit be carried through two signal lines, so two pins are needed. It also

requires external resistor termination.

The full implementation of the LVDS transmitter and receiver is shown in an example in

Figure 2-11. The building blocks of the LVDS transmitter-receiver are one transmitter macro, one

receiver macro, three board resistors at the transmitter end, and one resistor at the receiver end.

The values for the three driver resistors are different from those used in the LVPECL

implementation because the output standard specifications are different.

Along with LVDS I/O, ProASIC3 also supports Bus LVDS structure and Multipoint LVDS (M-LVDS)

configuration (up to 40 nodes).

B-LVDS/M-LVDS

Bus LVDS (B-LVDS) and Multipoint LVDS (M-LVDS) specifications extend the existing LVDS standard

to high-performance multipoint bus applications. Multidrop and multipoint bus configurations

may contain any combination of drivers, receivers, and transceivers. Actel LVDS drivers provide the

higher drive current required by B-LVDS and M-LVDS to accommodate the loading. The drivers

require series terminations for better signal quality and to control voltage swing. Termination is

also required at both ends of the bus since the driver can be located anywhere on the bus. These

configurations can be implemented using the TRIBUF_LVDS and BIBUF_LVDS macros along with

appropriate terminations. Multipoint designs using Actel LVDS macros can achieve up to 200 MHz

with a maximum of 20 loads. A sample application is given in Figure 2-12. The input and output

buffer delays are available in the LVDS section in Table 2-92.

Example: For a bus consisting of 20 equidistant loads, the following terminations provide the

required differential voltage, in worst-case Industrial operating conditions, at the farthest receiver:

RS=60Ω and RT=70Ω, given Z0=50Ω (2") and Zstub =50Ω (~1.5").

LVPECL

Low-Voltage Positive Emitter-Coupled Logic (LVPECL) is another differential I/O standard. It

requires that one data bit be carried through two signal lines. Like LVDS, two pins are needed. It

also requires external resistor termination.

The full implementation of the LVDS transmitter and receiver is shown in an example in

Figure 2-13. The building blocks of the LVPECL transmitter-receiver are one transmitter macro, one

receiver macro, three board resistors at the transmitter end, and one resistor at the receiver end.

The values for the three driver resistors are different from those used in the LVDS implementation

because the output standard specifications are different.

A3P250 Clock Tree Topology

Clock delays are device-specific. Figure 2-27 is an example of a global tree used for clock routing.

The global tree presented in Figure 2-27 is driven by a CCC located on the west side of the A3P250

device. It is used to drive all D-flip-flops in the device.

Global Tree Timing Characteristics

Global clock delays include the central rib delay, the spine delay, and the row delay. Delays do not

include I/O input buffer clock delays, as these are I/O standard–dependent, and the clock may be

driven and conditioned internally by the CCC module. For more details on clock conditioning

capabilities, refer to the "Clock Conditioning Circuits" section on page 2-92. Table 2-108 to

Table 2-114 on page 2-91 present minimum and maximum global clock delays within each device.

Minimum and maximum delays are measured with minimum and maximum loading.

Notes:

1. Maximum value obtained for a –2 speed-grade device in worst-case commercial conditions. For specific

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

2. This delay is a function of voltage and temperature. See Table 2-6 on page 2-6 for deratings.

3. TJ = 25°C, VCC = 1.5 V

4. The A3P030 device does not contain a PLL.

5. Tracking jitter is defined as the variation in clock edge position of PLL outputs with reference to the PLL

input clock edge. Tracking jitter does not measure the variation in PLL output period, which is covered by

the period jitter parameter.
