The Cypress CY7C024-15AC is a 64 Kbit dual-port asynchronous SRAM organized as 4K words of 16 bits each. Two independent ports with separate address, data, and control lines allow simultaneous reads and writes from two bus masters — typically a pair of microcontrollers, a DSP and an MCU, or a processor and an FPGA — without arbitration logic on the board. The 15 ns access time keeps bus turnaround tight enough for mid-speed embedded systems running at clock rates up to roughly 33 MHz. Supply range is 4.5V to 5.5V, placing it in the 5 V logic era.
That gives the bus master a window to latch the data before the next clock edge. For a system running a 25 MHz bus clock (40 ns period), 15 ns leaves 25 ns for address setup, hold, and propagation through buffers — workable with careful PCB routing. At 33 MHz (30 ns period), the margin shrinks to 15 ns, which demands tight layout and matched trace lengths on the address and data buses.
