The CY7C1031 and CY7C1032 are 64K by 18 synchronous cache RAMs designed to interface with high-speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 8.5 ns. A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access. The CY7C1031 is designed for Intel Pentium and i486 CPUbased systems; its counter follows the burst sequence of the Pentium and the i486 processors. The CY7C1032 is architected for processors with linear burst sequences. Burst accesses can be initiated with the processor address strobe (ADSP) or the cache controller address strobe (ADSC) inputs. Address advancement is controlled by the address advancement (ADV ) input.
