Decryption
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 ProASIC
tiles. The ProASIC3 VersaTile supports the following:
