4K × 16 and 8K × 16/18 Dual-Port Static RAM with SEM, INT, BUSY
Features
■ True dual-ported memory cells that allow simultaneous reads of the same memory location
■ 4K × 16 organization (CY7C024E) ■ 8K × 16 organization (CY7C025E) ■ 8K × 18 organization (CY7C0251E) ■ 0.
35-µ complementary metal oxide semiconductor (CMOS) for
optimum speed and power ■ High-speed access: 15 ns ■ Low operating power: ICC = 180 mA (typ), ISB3 = 0.
05 mA (typ) ■ Fully asynchronous operation ■ Automatic power-down ■ Expandable data bus to 32/36 bits or more using master/slave
chip select when using more than one device ■ On-chip arbitration logic ■ Semaphores included to permit software handshaking
between ports ■ INT flag for port-to-port communication ■ Separate upper-byte and lower-byte control ■ Pin select for master or slave ■ Available in Pb-free 100-pin thin quad flatpack ...
