CY7C1061GN30-10ZXI is a 16-Mbit (1M × 16) asynchronous CMOS SRAM with 10 ns access time. It operates from 2.2 V to 3.6 V over the industrial range (−40°C to +85°C) and supports automatic power-down when deselected. It provides 20 address lines (A0–A19), 16-bit I/O with BLE/BHE byte writes, TTL-compatible levels, 1.0 V data retention, and a Pb-free 48-pin TSOP I (ZX) package for bus-oriented memory expansion.
