M48Z58-70PC1 Information

Description

The M48Z58-70PC1 is a non-volatile static RAM (NVRAM) component from STMicroelectronics. It features 64K bits of memory, organized as 8K x 8 SRAM, with a access time of 70ns. The device has a built-in lithium power source and requires only a 5V power supply. It offers 10 years minimum data retention in the absence of power, automatic power-fail chip deselect, and WRITE protection. The M48Z58-70PC1 is designed for applications requiring non-volatile SRAM with real-time clock/calendar capabilities. Its features make it suitable for industrial control systems, medical equipment, automotive systems, and telecommunications equipment that require reliable data storage and accurate timekeeping even in the event of power loss.

Features

The M48Z58-70PC1 features include:

5V power supply
Integrated lithium power source
8K x 8 non-volatile static RAM (NVRAM)
10 years minimum data retention in the absence of power
Automatic power-fail chip deselect and WRITE protection

These features make it suitable for applications requiring non-volatile SRAM with a real-time clock/calendar, such as industrial control systems, medical equipment, automotive systems, and telecommunications equipment.

Package

The package type of M48Z58-70PC1 is PCDIP-28.

Pinout

The M48Z58-70PC1 has a package type of PCDIP-28, which means it has 28 pins.
