CY62128VLL-70ZC

The CY62128VLL-70ZC is a 128K x 8 Static RAM (SRAM) manufactured by Cypress Semiconductor. This high-performance CMOS device offers efficient memory expansion with its Chip Enable (CE) and Output Enable (OE) features. It operates within a low voltage range, supporting multiple voltage levels including 2.7V-3.6V, 2.3V-2.7V, and 1.6V-2.0V depending on the specific variant.

Designed for low active power and standby power consumption, the CY62128VLL-70ZC includes an automatic power-down feature that reduces power usage by over 99% when the device is deselected. The inputs and outputs are TTL-compatible, ensuring ease of integration into existing systems. Data is written by asserting Chip Enable one (CE1) and Write Enable (WE) low while Chip Enable two (CE2) is high. Reading data is accomplished by asserting CE1 and Output Enable (OE) low, with WE and CE2 high.

This SRAM is available in several standard package types, including 450-mil-wide SOIC, 32-lead TSOP-I, and STSOP packages, all suitable for surface mount applications. The eight input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected, outputs are disabled, or during a write operation.
