CY7C1399B

CY7C1399B 256K(32K x 8) Static RAM Features Single 3.3V power supply Ideal for low-voltage cache memory applications High speed — 10/12/15 ns Low active power — 216 mW (max.) Low-power alpha immune 6T cell Plastic SOJ and TSOP packaging Functional Description[1] The CY7C1399B is a high-performance 3.3V CMOS Static RAM organized as 32,768 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE) and Logic Block Diagram A0 A1 A2 AA34 A5 A6 AA78 A9 CE WE OE ROW DECODER SENSE AMPS INPUT BUFFER 32K x 8 ARRAY COLUMN DECODER POWER DOWN active LOW Output Enable (OE) and three-state drivers. The device has an automatic power-down feature, reducing the power consumption by more than 95% when deselected. An active LOW Write Enable signal (WE) controls the writing/reading operation of the memory. When CE and WE inputs are both LOW, data on the eight data input/output pins (I/O0 through I/O7) is written into the memory location addresse...
