Fusion Family of Mixed Signal FPGAs
Embedded Memories
Fusion devices include four types of embedded memory: flash block, FlashROM, SRAM, and FIFO.
Flash Memory Block
Fusion is the first FPGA that offers a flash memory block (FB). Each FB block stores 2 Mbits of data. The
flash memory block macro is illustrated in
The port pin name and descriptions are detailed

All flash memory block signals are active high, except for CLK and active
low RESET. All flash memory operations are synchronous to the rising edge of CLK.
