STMICROELECTRONICS M48Z35/M48Z35Y 256 Kbit (32 Kbit x8) ZEROPOWER SRAM handbook
The STMicroelectronics M48Z35 and M48Z35Y ZeroPower SRAMs are 32 Kbit × 8 non‑volatile static RAM devices that integrate power‑fail detection and a battery‑backed memory cell on a single die. The handbook provides a detailed description of the device architecture, pin functions, and the two available package options – a 28‑pin CAPHAT™ DIP and a 28‑lead SOIC with a separate SNAPHAT battery module.
Operating modes such as READ, WRITE, Data Retention, and Power‑Down/Up are explained with timing diagrams and electrical characteristics. The document also lists absolute maximum ratings, DC/AC parameters, mechanical dimensions, ordering information, and revision history, making it a comprehensive reference for designers and technicians.
