STMicroelectronics 64 kB 100 ns NVRAM 28-Pin PCDIP M48T08-100PC1

STMicroelectronics M48T08-100PC1 is an advanced 64 kB 100 ns non-volatile RAM (NVRAM) module featuring a 28-pin PCDIP through-hole package. It is specifically designed for applications requiring reliable real-time clock functions combined with non-volatile memory storage.

This NVRAM integrates a TIMEKEEPER® SRAM technology that combines traditional SRAM memory with a low-power quartz oscillator and a battery to maintain accurate clock and calendar data even during power interruptions. The device interfaces through a fast parallel 8-bit data bus and supports an 8K x 8-bit memory organization.

With a maximum random access time of 100 ns, it offers rapid data access suitable for timing-critical industrial, laboratory, embedded systems, and communication equipment. The device supports operating temperatures ranging from 0°C to 70°C, making it robust for commercial-grade electronics.

Its electrical characteristics include a minimum supply voltage of 4.75 V, maximum supply voltage of 5.5 V, and a typical supply current of 80 mA, ensuring stable operation with standard 5 V power lines.

The compact 28-pin PCDIP package measures 39.88 mm in length, 18.34 mm in width, and 8.89 mm in height, facilitating easy integration on printed circuit boards using through-hole mounting techniques.

Manufactured in Malaysia, the M48T08-100PC1 meets industrial quality standards though it holds no specific certifications or automotive standards. Features 64 kB memory size with 8K x 8-bit organization. Offers 100 ns maximum random access time for fast data retrieval.

Utilizes a parallel interface with 8-bit data bus width. Mount type is through hole in a 28-pin PCDIP package. Operating temperature range from 0°C to 70°C. Supply voltage range of 4.75 V to 5.5 V and current of 80 mA. TIMEKEEPER® SRAM provides real-time clock with quartz oscillator and built-in battery backup.

Compact dimensions and robust design support industrial and embedded applications. Manufactured in Malaysia with quality assurance.
