STMicroelectronics 64kB 150 ns Non-Volatile RAM NVRAM 28-Pin PCDIP M48T08-150PC1

STMicroelectronics M48T08-150PC1 is a high-performance 64kB Non-Volatile RAM (NVRAM) with a 150 ns maximum random access time, packaged in a 28-pin PCDIP form factor designed for through-hole mounting. It combines SRAM functionality with non-volatile memory benefits, making it ideal for applications requiring fast access and data retention without continuous power.

The device is organized as 8K x 8 bits, providing a byte-wide data interface with a parallel connection for straightforward integration into digital systems. Operating voltage ranges from 4.75V to 5.5V with a supply current of 80 mA, and it supports an operating temperature range from 0°C to 70°C to accommodate typical industrial environments.

The M48T08-150PC1 incorporates a CAPHAT™ package that houses both a quartz crystal and a long-life lithium button cell, enabling battery-backed memory retention and real-time clock capabilities. This integration allows the device to maintain data integrity and timekeeping even when main power is removed.

Its design ensures compatibility with standard ROM, EPROM, and EEPROM sockets and acts as a drop-in replacement for JEDEC standard 8 K x 8 SRAM components without requiring special write timing or imposing limitations on write cycles.

This product supports industrial, laboratory, and embedded system applications requiring reliable non-volatile memory with fast access speeds and longevity. The robust packaging and proven STMicroelectronics quality make it suitable for manufacturing, communication equipment, and control systems.

This NVRAM has a memory size of 64kB organized as 8K x 8 bits. The device interface is parallel, with an 8-bit data bus width for efficient data transfer. Maximum random access time of 150 nanoseconds ensures fast memory operations.

It operates at voltages between 4.75V minimum and 5.5V maximum with a supply current of 80 mA. Operating temperature ranges from 0°C to 70°C, suitable for standard industrial environments. The 28-pin PCDIP package measures 39.88mm length, 18.34mm width, and 8.89mm height.

The product includes a CAPHAT™ housing with integrated quartz crystal and lithium button cell for battery-backed operation. This device is a non-volatile, pin and function equivalent to the JEDEC standard 8 K x 8 SRAM, requiring no special write timing or write cycle limitations.
