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 Figure 2-32. The port pin name and descriptions are detailed
on Table 2-19 on page 2-42. 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.
