Product Description

STMicroelectronics M48Z35-70PC1 is a 256 kB non-volatile SRAM (NVRAM) featuring a fast 5 ns maximum random access time, packaged in a 28-pin PCDIP suitable for through-hole mounting. This device integrates low-power static RAM with a power-fail control circuit and a durable lithium battery, ensuring data retention even during power interruptions.

The memory is organized as 32K x 8 bit with an 8-bit parallel data bus interface, allowing seamless integration with embedded systems and industrial applications requiring reliable, fast-access non-volatile memory.

Operating voltage ranges from 4.75 to 5.5 volts with a typical standby supply current of 20 mA, making it energy efficient for power-sensitive designs. Its operational temperature range spans from 0°C to 70°C, making it suitable for moderate industrial and commercial environments.

Physically, the NVRAM measures 39.88 mm in length, 18.34 mm in width, and 9.65 mm in height, compliant with standard 28-pin PCDIP footprint, facilitating easy replacement or integration.

This NVRAM eliminates data loss risks associated with power failures through its ZEROPOWER® technology. It is compatible with a wide range of embedded control systems requiring stable memory retention. Ideal for industrial, instrumentation, telecommunications, and automotive-adjacent applications excluding strict automotive standard compliance.

The package pin count of 28 supports various legacy and current system architectures. Long-life internal lithium battery ensures up to 10 years of data retention under normal conditions.

Choose this STMicroelectronics NVRAM for high-performance, dependable memory storage with stable electrical characteristics and compact form factor. EnvMart provides this product with verified specifications for quality and functionality assurance.
