STMicroelectronics M48Z08-70PC1 Zero Power SRAM

The M48Z08-70PC1 is a 64 Kbit (8K x 8) Zero Power SRAM manufactured by STMicroelectronics. This non-volatile memory integrates a fully static SRAM with a self-contained lithium energy source and control circuitry which constantly monitors V_CC for an out-of-tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption.

Operating at a speed of 70ns, the M48Z08 offers fast access times to meet the requirements of high-speed microprocessors. The SRAM provides unlimited read and write operations in the absence of power and has a data retention period of over 10 years in the absence of power. This makes it an ideal choice for memory applications where reliable non-volatility is critical, such as real-time clocks, microprocessor-based systems, and other demanding data integrity applications.

Encased in a 28-pin, 600 mil DIP package, the M48Z08-70PC1 ensures easy integration into a wide range of applications. It operates within a temperature range of 0°C to 70°C, making it suitable for commercial-grade applications. Additionally, the device supports a standard PC board layout used for 28-pin DIPs, which allows for a straightforward design-in process.

This memory module is designed with the industry-standard JEDEC pinout, which simplifies the integration into existing designs. The power-saving feature of the M48Z08-70PC1 is particularly beneficial for battery-backed systems, as it helps to preserve the life of the battery, ensuring that data is retained even when the main power is lost.

Key features of the M48Z08-70PC1 include:

• 64 Kbit (8Kb x 8) non-volatile SRAM
• Unlimited write cycles
• Read cycle time of 70ns
• Automatic power-fail chip deselect and write protection
• Self-contained battery with over 10 years of data retention
• JEDEC standard 28-pin DIP package

Overall, the M48Z08-70PC1 from STMicroelectronics is a reliable and robust memory solution that offers the assurance of data integrity and the convenience of zero-power operation.
