Figure 1-2 • ProASIC3 Device Architecture Overview with Four I/O Banks (A3P250, A3P600, and A3P1000)
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 Microsemi 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.
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
Refer to Figure 1-3 for VersaTile configurations.
