The M48Z02-70PC1 is a 16 Kbit (2Kb x 8) ZEROPOWER® SRAM with a 70ns access time. This high-performance product, designed by STMicroelectronics, is a non-volatile static RAM which integrates a fully functional battery-backed memory and a real-time clock (RTC) in a single package. The integration of power-fail deselect circuitry and battery control logic on the chip enhances the reliability and longevity of the memory storage.
Key Features
- Memory Storage: 16 Kbit (2Kb x 8) of static RAM with non-volatile, battery-backed data retention.
- Access Time: Fast access time of 70ns, allowing for efficient data retrieval.
- Power Source: Integrated, replaceable, long-life lithium battery maintains data and real-time clock operation for over 10 years in the absence of power.
- Real-Time Clock: An embedded RTC provides timekeeping with precision in seconds, minutes, hours, day, date, month, and year formats.
- Automatic Power-Fail Chip Deselect: Ensures data retention by automatically switching to the battery supply during power failures.
- Low Power Consumption: ZEROPOWER® technology significantly reduces power consumption, making it ideal for energy-sensitive applications.
- Packaging: Housed in a 24-pin, 600 mil DIP CAPHAT™ package, suitable for standard PCB layouts.
- Compatibility: Directly replaces standard 2K x 8 volatile static RAM or EEPROM, offering non-volatile data retention without battery concerns.
