4155I–AERO–06/06 proven functions. The Automatic Component Generators work seamlessly with industry- standard schematic and synthesis tools to cr eate the fastest, most efficient designs available. The patented AT40KEL040 series architecture employs a symmetrical grid of small yet powerful cells connected to a flexible busing network. Independentl y controlled clocks and resets govern every column of cells. The array is surrounded by programmable I/O. Devices offer 46,000 usable ASIC gates, and have 3,056 registers. AT40K series FPGAs utilize a reliable 0.35µm single-poly, 4-metal CMOS process and are 100% fac- tory-tested. Atmel’s PC- and workstation-based integrated development system (IDS) is used to create AT40KEL040 series designs. Multiple design entry methods are sup- ported. The Atmel architecture was de veloped to provide the high est levels of performance, functional density and design fl exibility in an FPGA. The ce lls 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 multiply ing the functionality in each cell. A simple, high-speed busing network provides fast, efficient communicati on over medium and long distances. AT40KEL040 Configurator Statistics extracted from configuration bitstreams show that the maximum needed size is 1Mbit. In order to keep the maximum number of pins assigned to signals, it is recommended to use a serial configuration interface. This is the reason why Atmel proposes a 1Mbit serial EEPROM for configuring the AT40KEL040, the AT17LV010-10DP which is also a 3.3V bias chip. It is packaged into a 28-pin DIL Flat Pack 400mils wide. This memory has been tested for total dose under bias and unbiased conditions, exhib- iting far better results when unbiased; this is the reason why it is recommended to switch off the memory when it is not in the configuration mode. In addition, heavy ions tests have shown that the data stored in the memory cells are not corrupted eventhough errors may be detected while downloading the bitstream; this is the result of the data serializ ation from the parallel memory plan; therefore, it is recom- mended to use the FPGA CRC while configuring it, and to resume the configuration when an error is detected.

At the heart of the Atmel architecture is a sy mmetrical array of identical cells (Figure 1). Note: 1. The right-most column can only be used as single-port RAM. Figure 1. Symmetrical Array Surrounded by I/O Note: AT40K has registered I/Os. Group enable every sector for tri-states on obuf’s.

4155I–AERO–06/06 Clocking Scheme There are eight Global Clock buses (GCK1 - GCK8) on the AT40KEL040 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 specificat ion. Even the derive d 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 Col- umn 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 “0”, 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 10 on page 15) . 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 addit ional 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 configura- tion on power-up, constant “0” is provided to each register’s clock pins. After configura- tion on power-up, the registers either set or reset, depending on the user’s choice. The clocking scheme is designed to allow effi cient use of multiple clocks with low clock skew, both within a column and across the core cell array.

Figure 10. Clocking (for One Column of Cells)

16 AT40KEL040

4155I–AERO–06/06 Set/Reset Scheme The AT40KEL040 family reset scheme is ess entially 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 fo r 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 (Figure 11 on page 17). 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. Be fore configuration on power-up, a logic 1 (a high) is provided by each register (i.e., all registers are set at power-up).

4155I–AERO–06/06 I/O Structure AT40K has registered I/Os and group enable every sector for tri-states on obuf’s. Pad The I/O pad is the one that connects the I/O to the outside world. Note that 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. Pull-up/Pull-down Each pad has a programmable pull-up and pull-down attached to it. This supplies a weak “1” or “0” 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. CMOS The threshold level is a CMOS-compatible level. Schmitt A Schmitt trigger circuit can be enabled on the inputs. The Schmitt trigger is a regenera- tive comparator circuit that adds 1V hysteresis to the input. This effectively improves the rise and fall times (leading and trailing e dges) of the incoming signal and can be useful for filtering out noise. 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 require- ments for the input signal. Drive The output drive capa bilities of each I/O are programm able. They can be set to FAST, MEDIUM or SLOW (using IDS tool). The F AST setting has the highest drive capability (16 mA at 3.3V) buffer and the fastest slew rate. MEDIUM produces a medium drive (12 mA at 3.3V) buffer, while SLOW yields a standard (4 mA at 3.3V) buffer. 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. Source Selection Mux The Source Selection mux sele cts the source for the output signal of an I/O. See Figure 12 on page 21. Primary, Secondary and Corner I/Os The AT40KEL040 has three kinds of I/Os: Primary I/O, Secondary I/O and a Corner I/O. Every edge cell except corner cells on the AT40KEL040 has access to one Primary I/O and two Secondary I/Os. 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 interf aces directly to its adjacent core cell. It also connects into the repeaters on the ro w 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 Prim ary I/O can be accessed from any logic cell on three separate rows or columns of the FPGA. See Figures 12a and 13a. 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 loca ted between core cell locations. This I/O

4155I–AERO–06/06 connects on the diagonal inputs to the cell ab ove 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 fea- ture, 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 12a and Figure 13b. 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 and 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 AT40KEL040 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 net- works running along the edges of the array. This means that many different edge logic cells can access the Corner I/Os. See Figure 14.
