M48Z18-100PC1
Overview
The M48Z18-100PC1 is an 8K x 8 non-volatile SRAM (NVSRAM) that combines a low-power CMOS SRAM with a built-in lithium battery and power-fail control circuitry. Housed in a 28-pin CAPHAT package, it provides 64Kbits of memory with an access time of 100 ns and protects data during power loss without requiring external components. This device is pin-compatible with standard JEDEC 8K x 8 SRAMs, making it a drop-in solution for critical data retention.
Why Choose This Part
The integrated CAPHAT package simplifies board design by eliminating the need for external battery backup circuitry and separate power management ICs. It offers unlimited write cycles, avoiding the endurance limitations of EEPROM or Flash memory, while providing automatic write protection when Vcc falls below the power-fail deselect voltage.
Applications
Key Specifications
Getting Started
To use this part, interface it with any standard 8-bit parallel bus as if it were a standard SRAM; no special drivers or software protocols are required. Ensure the power supply is stable between 4.5V and 5.5V, and note that the internal battery is already connected and ready for use upon delivery. Reference the STMicroelectronics datasheet for timing diagrams to ensure the 100 ns access time matches your processor requirements.
