Overview
CY62256 256K (32K x 8) Static RAM Features • High speed: 55 ns and 70 ns • Voltage range: 4.
5V–5.
5V operation • Low active power (70 ns, LL version) — 275 mW (max.
) • Low standby power (70 ns, LL version) — 28 µW (max.
) • Easy memory expansion with CE and OE features • TTL-compatible inputs and outputs • Automatic power-down when deselected • CMOS for optimum speed/power • Package available in a standard 450-mil-wide (300-mil body width) 28-lead narrow SOIC, 28-lead TSOP-1, 28-lead reverse TSOP-1, and 600-mil 28-lead PDIP packages Functional Description[1] The CY62256 is a high-performance CMOS static RAM organized as 32K words by 8 bits.
Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and three-state drivers.
This device has an automatic power-down feature, reducing the power consumption by 99.
9% when deselected.
An active LOW write enable signal (WE) controls the writing/reading operation of the memory.
When CE and WE inputs are...
