This document describes the features and characteristics of the 256K (32K x 8) Static RAM produced by Cypress Semiconductor Corporation, including temperature ranges, speed, low voltage range, low power consumption, easy memory expansion, TTL-compatible inputs and outputs, etc.
The CY62256VN static RAM offers 256 Kbits organized as 32 K × 8. It features low‑voltage operation (2.7 V–3.6 V), automatic power‑down when deselected, and TTL‑compatible I/O. The device supports multiple temperature ranges, from commercial (0 °C‑70 °C) to automotive‑E (‑40 °C‑125 °C).
The chip is available in several 28‑lead packages, including narrow SOIC, TSOP‑I, and reverse‑TSOP‑I, with both Pb‑free and non‑Pb‑free options. Key electrical characteristics include a 70 ns access time, typical operating supply current of 11 mA, and standby current as low as 0.1 µA.
