Table 1. AT40KAL Family(1)

Note: 1. Packages with FCK will have eight less registers.

1. Description

The AT40KAL is a family of fully PCI-compliant, SRAM-based FPGAs with distributed 10ns programmable

synchronous/asynchronous, dual-port/single-port SRAM, eight global clocks, Cache Logic ability (partially or fully

reconfigurable without loss of data), automatic component generators, and range in size from 5,000 to 50,000

usable gates. I/O counts range from 114 to 161 in industry standard packages ranging from 144-pin LQFP to

208-pin PQFP, and support 3.3V designs.

The AT40KAL is designed to quickly implement high-performance, large gate count designs through the use of

synthesis and schematic-based tools used on a PC or Sun platform. The Atmel design tools provide seamless

integration with industry standard tools such as Synplicity, ModelSim, Exemplar, and Viewlogic.

The AT40KAL can be used as a coprocessor for high-speed (DSP/processor-based) designs by implementing a

variety of computation intensive, arithmetic functions. These include adaptive finite impulse response (FIR) filters,

fast Fourier transforms (FFT), convolvers, interpolators and discrete-cosine transforms (DCT) that are required for

video compression and decompression, encryption, convolution, and other multimedia applications.

1.1 Fast, Flexible, and Efficient SRAM

The AT40KAL FPGA offers a patented distributed 10ns SRAM capability where the RAM can be used without

losing logic resources. Multiple independent, synchronous or asynchronous, and dual-port or single-port RAM

functions (FIFO, scratch pad, etc.) can be created using Atmel’s macro generator tool.

1.2 Fast, Efficient Array, and Vector Multipliers

The AT40KAL’s patented 8-sided core cell with direct horizontal, vertical and diagonal cell-to-cell connections

implements ultra fast array multipliers without using any busing resources. The AT40KAL Cache Logic capability

enables a large number of design coefficients and variables to be implemented in a very small amount of silicon,

enabling vast improvement in system speed at much lower cost than conventional FPGAs.

Atmel-2818G-FPGA-AT40KAL-Series-Datasheet_092013

1.3 Cache Logic Design

The AT40KAL, AT6000, and FPSLIC families are capable of implementing Cache Logic (dynamic full/partial logic

reconfiguration, without loss of data, on-the-fly) for building adaptive logic and systems. As new logic functions are

required, they can be loaded into the logic cache without losing the data already there or disrupting the operation of

the rest of the chip; replacing or complementing the active logic. The AT40KAL can act as a reconfigurable

coprocessor.

1.4 Automatic Component Generators

The AT40KAL FPGA family is capable of implementing user-defined, automatically generated, macros in multiple

designs; speed and functionality are unaffected by the macro orientation or density of the target device. This

enables the fastest, most predictable and efficient FPGA design approach, and minimizes design risk by reusing

already proven functions. The Automatic Component Generators work seamlessly with industry standard

schematic and synthesis tools to create the fastest, most efficient designs available.

The patented AT40KAL series architecture employs a symmetrical grid of small yet powerful cells connected to a

flexible busing network. Independently controlled clocks and resets govern every column of cells. The array is

surrounded by programmable I/O.

Devices range in size from 5,000 to 50,000 usable gates in the family, and have 256 to 3,048 registers. Pin

locations are consistent throughout the AT40KAL series for easy design migration in the same package footprint.

The AT40KAL series FPGAs utilize a reliable 0.35μ triple-metal, CMOS process and are 100% factory-tested. The

Atmel PC- based integrated development system (IDS) is used to create AT40KAL series designs. Multiple design

entry methods are supported.

The Atmel architecture was developed to provide the highest levels of performance, functional density, and design

flexibility in an FPGA. The cells in the Atmel array are small, efficient, and can implement any pair of Boolean

functions of (the same) three inputs or any single Boolean function of four inputs. The cell’s small size leads to

arrays with large numbers of cells, greatly multiplying the functionality in each cell. A simple, high-speed busing

network provides fast, efficient communication over medium and long distances.

2. The Symmetrical Array

At the heart of the Atmel architecture is a symmetrical array of identical cells, seeFigure 2-1. The array is

continuous from one edge to the other, except for bus repeaters spaced every four cells, see Figure 2-2. At the

intersection of each repeater row and column, there is a 32 x 4 RAM block accessible by adjacent buses. The RAM

can be configured as either a single-ported or dual-ported RAM*, with either synchronous or asynchronous

operation.

Note: 1. AT40KAL has registered I/Os. Group enable on every sector for tri-states on obufe’s.

plane. Each repeater has connections to two adjacent local-bus segments and two express-bus segments. This is

3. The Busing Network

Figure 3-1 depicts one of five identical busing planes. Each plane has three bus resources: a local-bus resource

(the middle bus) and two express-bus (both sides) resources. Bus resources are connected via repeaters. Each

repeater has connections to two adjacent local-bus segments and two express-bus segments. Each local-bus

segment spans four cells and connects to consecutive repeaters. Each express-bus segment spans eight cells and

“leapfrogs” or bypasses a repeater. Repeaters regenerate signals and can connect any bus to any other bus (all

pathways are legal) on the same plane. Although not shown, a local bus can bypass a repeater via a

programmable pass gate allowing long on-chip tri-state buses to be created. Local/Local turns are implemented

through pass gates in the cell-bus interface. Express/Express turns are implemented through separate pass gates

distributed throughout the array.

Some of the bus resources on the AT40KAL are used as a dual-function resources. Table 3-1 shows which buses

are used in a dual-function mode and which bus plane is used. The AT40KAL software tools are designed to

accommodate dual-function buses in an efficient manner.

5. The Cell

Figure 5-1 depicts the AT40KAL cell. Configuration bits for separate muxes and pass gates are independent. All

permutations of programmable muxes and pass gates are legal. Vn (V1 – V5) is connected to the vertical local bus

in plane n. Hn (H1 – H5) is connected to the horizontal local bus in plane n. A local/local turn in plane n is achieved

by turning on the two pass gates connected to Vn and Hn. Pass gates are opened to let signals into the cell from a

local bus or to drive a signal out onto a local bus. Signals coming into the logic cell on one local bus plane can be

switched onto another plane by opening two of the pass gates. This allows bus signals to switch planes to achieve

greater route ability. Up to five simultaneous local/local turns are possible.

The AT40KAL FPGA core cell is a highly configurable logic block based around two 3-input LUTs (8 x 1 ROM),

which can be combined to produce one 4-input LUT. This means any core cell can implement two functions of

three inputs or one function of four inputs. There is a Set/Reset D flip-flop in every cell, the output of which may be

tri-stated and fed back internally within the core cell. There is also a 2-to-1 multiplexer in every cell, and an

upstream AND gate in the “front end” of the cell. This AND gate is an important feature in the implementation of

efficient array multipliers.

With this functionality in each core cell, the core cell can be configured in several “modes”. The core cell flexibility

makes the AT40KAL architecture well suited to most digital design application areas, see Figure 5-2.

Tri-state/Mux Mode. This mode is used in many

telecommunications applications, where data needs

to be routed through more than one possible path.

The output of the core cell is very often tri-statable

for many inputs to many outputs data switching.

2:1 MUX

Synthesis Mode. This mode is particularly important

for the use of VHDL/Verilog design. VHDL/Verilog

Synthesis tools generally will produce as their output

large amounts of random logic functions. Having a

4-input LUT structure gives efficient random logic

optimization without the delays associated with

larger LUT structures. The output of any cell may be

registered, tri-stated and/or fed back into a core cell.

Arithmetic Mode. Frequently used in many designs.

As can be seen in the figure, the AT40KAL core cell

can implement a 1-bit full adder (2-input adder with

both Carry In and Carry Out) in one core cell. Note

that the sum output in this diagram is registered. This

output could then be tri-stated and/or fed back into

the cell.

efficiently implement array multipliers. An array

multiplier is an array of bitwise multipliers, each

structure fits very well into the AT40KAL architecture.

Counter Mode. Counters are fundamental to almost

all digital designs. They are the basis of state

machines, timing chains and clock dividers. A

counter is essentially an increment by one function

(i.e., an adder), with the input being an output (or a

decode of an output) from the previous stage. A 1-bit

counter can be implemented in one core cell. Again,

the output can be registered, tri-stated and/or fed

back.

6. RAM

32 x 4 dual-ported RAM blocks are dispersed throughout the array, see Figure 6-1.

A 4-bit Input Data Bus connects to four horizontal local buses distributed over four sector rows (plane 1).

A 4-bit Output Data Bus connects to four horizontal local buses distributed over four sector rows (plane 2).

A 5-bit Input Address Bus connects to five vertical express buses in the same column.

A 5-bit Output Address Bus connects to five vertical express buses in the same column.

Ain (input address) and Aout (output address) alternate positions in horizontally aligned RAM blocks.

For the left-most RAM blocks, Aout is on the left and Ain is on the right.

For the right-most RAM blocks, Ain is on the left and Aout is tied off; only be configured as a single port.

For the single-ported RAM, Ain is the READ/WRITE address port and Din is the (bi-directional) data port.

The Right-most RAM blocks can be used only for single-ported memories. WEN and OEN connect to the

vertical express buses in the same column.

Reading and writing of the 10ns 32 x 4 dual-port FreeRAM are independent of each other. Reading the 32 x 4

dual-port RAM is completely asynchronous. Latches are transparent; when Load is Logic 1, data flows through;

when Load is Logic 0, data is latched. These latches are used to synchronize Write Address, Write Enable Not,

and Din signals for a synchronous RAM. Each bit in the 32 x 4 dual-port RAM is also a transparent latch. The

front-end latch and the memory latch together form an edge-triggered flip flop. When a nibble (bit = 7) is (Write)

addressed and LOAD is Logic 1 and WE is Logic 0, data flows through the bit. When a nibble is not (Write)

addressed or LOAD is Logic 0 or WE is Logic 1, data is latched in the nibble. The two CLOCK muxes are controlled

together; they both select CLOCK (for a synchronous RAM) or they both select one (for an asynchronous RAM).

CLOCK is obtained from the clock for the sector-column immediately to the left and immediately above the RAM

block. Writing any value to the RAM clear byte during configuration clears the RAM (see the “AT40K/40KAL

Configuration Series” application note at www.atmel.com).

Figure 6-2. RAM Logic

Figure 6-3 shows an example of a RAM macro constructed using the AT40KAL FreeRAM cells. The macro shown

is a 128 x 8 dual-ported asynchronous RAM.

The very small amount of external logic required to complete the address decoding for the macro. Most

of the logic cells (core cells) in the sectors occupied by the RAM will be unused: they can be used for

other logic in the design. This logic can be automatically generated using the macro generators.

7. Clocking Scheme

There are eight Global Clock buses (GCK1 – GCK8) on the AT40KAL FPGA. Each of the eight dedicated Global

Clock buses is connected to one of the dual-use Global Clock pins. Any clocks used in the design should use

global clocks where possible: this can be done by using Assign Pin Locks to lock the clocks to the Global Clock

locations. In addition to the eight Global Clocks, there are four Fast Clocks (FCK1 – FCK4), two per edge column of

the array for PCI specification. For AT40KAL FPGAs, even the derived clocks can be routed through the Global

network. Access points are provided in the corners of the array to route the derived clocks into the global clock

network. The IDS software tools handle derived clocks to global clock connections automatically if used.

Each column of an array has a “Column Clock mux” and a “Sector Clock mux”. The Column Clock mux is at the top

of every column of an array and the Sector Clock mux is at every four cells. The Column Clock mux is selected

from one of the eight Global Clock buses. The clock provided to each sector column of four cells is inverted,

non-inverted or tied off to zero, using the Sector Clock mux to minimize the power consumption in a sector that has

no clocks. The clock can either come from the Column Clock or from the Plane 4 express bus, see Figure 7-1. The

extreme-left Column Clock mux has two additional inputs, FCK1 and FCK2, to provide fast clocking to left-side

I/Os. The extreme-right Column Clock mux has two additional inputs as well, FCK3 and FCK4, to provide fast

clocking to right-side I/Os.

The register in each cell is triggered on a rising clock edge by default. Before configuration on power-up, constant

zero is provided to each register’s clock pins. After configuration on power-up, the registers either set or reset,

depending on the user’s choice.

The clocking scheme is designed to allow efficient use of multiple clocks with low clock skew, both within a column

and across the core cell array.

8. Set/Reset Scheme

The AT40KAL family reset scheme is essentially the same as the clock scheme except that there is only one

Global Reset. A dedicated Global Set/Reset bus can be driven by any User I/O, except those used for clocking

(Global Clocks or Fast Clocks). The automatic placement tool will choose the reset net with the most connections

to use the global resources. You can change this by using an RSBUF component in your design to indicate the

global reset. Additional resets will use the express bus network.

The Global Set/Reset is distributed to each column of the array. Like Sector Clock mux, there is Sector Set/Reset

mux at every four cells. Each sector column of four cells is set/reset by a Plane 5 express bus or Global Set/Reset

using the Sector Set/Reset mux, see Figure 8-1. The set/reset provided to each sector column of four cells is either

inverted or non-inverted using the Sector Reset mux.

The function of the Set/Reset input of a register is determined by a configuration bit in each cell. The Set/Reset

input of a register is active low (Logic 0) by default. Setting or Resetting of a register is asynchronous. Before

configuration on power-up, a Logic 1 (a high) is provided by each register (i.e., all registers are set at power-up).

9. I/O Structure

9.1 Registered I/Os and Group Enable

The AT40KAL has registered I/Os and group enable every sector for tri-states on obuf’s.

9.1.1 PAD

The I/O pad is the one that connects the I/O to the outside world.

9.1.2 PULL-UP/PULL-DOWN

Each pad has a programmable pull-up and pull-down attached to it. This supplies a weak one or zero level to the

pad pin. When all other drivers are off, this control will dictate the signal level of the pad pin.

The input stage of each I/O cell has a number of parameters that can be programmed either as properties in

schematic entry or in the I/O Pad Attributes editor in IDS.

9.1.3 CMOS

The threshold level is a CMOS-compatible level.

9.1.4 SCHMITT

A Schmitt trigger circuit can be enabled on the inputs. The Schmitt trigger is a regenerative comparator circuit that

adds 1V hysteresis to the input. This effectively improves the rise and fall times (leading and trailing edges) of the

incoming signal and can be useful for filtering out noise.

9.1.5 DELAYS

The input buffer can be programmed to include four different intrinsic delays as specified in the AC timing

characteristics. This feature is useful for meeting data hold requirements for the input signal.

9.1.6 DRIVE

The output drive capabilities of each I/O are programmable. They can be set to FAST, MEDIUM or SLOW (using

IDS tool). The FAST setting has the highest drive capability (20 mA at 5V) buffer and the fastest slew rate.

MEDIUM produces a medium drive (14 mA at 5V) buffer, while SLOW yields a standard (6 mA at 5V) buffer.

9.1.7 TRI-STATE

The output of each I/O can be made tri-state (0, 1 or Z), open source (1 or Z) or open drain (0 or Z) by

programming an I/O’s Source Selection mux. Of course, the output can be normal (0 or 1), as well.

9.1.8 SOURCE SELECTION MUX

The Source Selection mux selects the source for the output signal of an I/O.

Not all I/Os have pads: the ones without pads are called Unbonded I/Os. The number of

unbonded I/Os varies with the device size and package. These unbonded I/Os are used to

perform a variety of bus turns at the edge of the array.

AT40KAL Series FPGA [Datasheet]

Atmel-2818G-FPGA-AT40KAL-Series-Datasheet_092013

9.2 Primary, Secondary, and Corner I/Os

The AT40KAL has three kinds of I/Os:

Primary I/O

Secondary I/O

Corner I/O

Every edge cell except corner cells on the AT40KAL has access to one Primary I/O and two Secondary I/Os.

9.2.1 Primary I/O

Every logic cell at the edge of the FPGA array has a direct orthogonal connection to and from a Primary I/O cell.

The Primary I/O interfaces directly to its adjacent core cell. It also connects into the repeaters on the row

immediately above and below the adjacent core cell. In addition, each Primary I/O also connects into the busing

network of the three nearest edge cells. This is an extremely powerful feature, as it provides logic cells toward the

center of the array with fast access to I/Os via local and express buses. It can be seen from the diagram that a

given Primary I/O can be accessed from any logic cell on three separate rows or columns of the FPGA. See Figure

9-1.

9.2.2 Secondary I/O

Every logic cell at the edge of the FPGA array has two direct diagonal connections to a Secondary I/O cell. The

Secondary I/O is located between core cell locations. This I/O connects on the diagonal inputs to the cell above

and the cell below. It also connects to the repeater of the cell above and below. In addition, each Secondary I/O

also connects into the busing network of the two nearest edge cells. This is an extremely powerful feature, as it

provides logic cells toward the center of the array with fast access to I/Os via local and express buses. It can be

seen from the diagram that a given Secondary I/O can be accessed from any logic cell on two rows or columns of

the FPGA. See Figure 9-2.

9.2.3 Corner I/O

Logic cells at the corner of the FPGA array have direct-connect access to five separate I/Os:

2 Primary

2 Secondary

1 Corner I/O

Corner I/Os are like an extra Secondary I/O at each corner of the array. With the inclusion of Corner I/Os, an

AT40KAL FPGA with n x n core cells always has 8n I/Os. As the diagram shows, Corner I/Os can be accessed

both from the corner logic cell and the horizontal and vertical busing networks running along the edges of the array.

11.3 Power-On Power Supply Requirements

Atmel FPGAs require a minimum rated power supply current capacity to insure proper initialization, and the power

supply ramp-up time does affect the current required. A fast ramp-up time requires more current than a slow

ramp-up time.

Table 11-1. Power-On Power Supply Requirements(1)

Notes: 1. This specification applies to Commercial and Industrial grade products only.

2. Devices are guaranteed to initialize properly at 50% of the minimum current listed above. A larger capacity power

supply may result in a larger initialization current.

3. Ramp-up time is measured from 0VDC to 3.6VDC. Peak current required lasts less than 2ms, and occurs near the

internal power on reset threshold voltage.
