Table 19. SPI Flash Memory Pin Information
SRAM
The board is populated with a Cypress 1-Mbit (128K x 8) Static RAM with a data bus width of 8 bits. The 15-bit
address bus, the data bus and the control signals are connected directly to the CPLD. The 15-bit address bus,
named MEMORY_A0 through MEMORY_A14, addresses 1-byte locations.
A 1Mb asynchronous SRAM is located at the bottom-center of the board.
