CY62138FLL-45SXIT is a 2-Mbit (256K × 8) CMOS static RAM for 5 V systems, specified at 45 ns access. It operates from 4.5 V to 5.5 V over -40°C to +85°C, with automatic chip-enable power-down (ISB2 5 µA max). Active ICC is 2.5 mA max at 1 MHz (18 mA max at fmax). It supports TTL-level inputs (VIH min 2.2 V) for direct processor interfacing and is offered in 32-pin SOIC Pb-free packages.
