Microchip 16 kB SPI EEPROM 230 ns 8-Pin SOP 25LC160B-I/MS

Microchip 25LC160B-I/MS is a 16 kB electrically erasable programmable read-only memory (EEPROM) designed for non-volatile data storage with fast 230 ns maximum random access time. It employs a simple serial peripheral interface (SPI), requiring only clock input (SCK), and separate data input (SI) and output (SO) pins. A chip select (CS) pin controls device access, while a hold pin (HOLD) permits temporary pausing of communication to service higher priority interrupts without losing data synchronization.

This device is built using low power CMOS technology, operating between 2.5V and 5.5V, making it suitable for a wide range of electronic industrial and commercial applications including embedded system memory, data logging, and industrial control systems. The maximum clock frequency is 3 MHz, with a memory configuration of 2048 x 8 bits arranged in 32-byte pages for efficient write operations.

The compact surface mount SOP package measures 3 mm in length, 3 mm in width, and 0.95 mm in height, featuring 8 pins for minimal PCB footprint. The operating temperature range of -40°C to 85°C ensures functionality in harsh and industrial environments. Data retention is rated at 200 years, providing reliable long-term memory storage.

This EEPROM supports self-timed erase and write cycles, with maximum write cycle time of 5 ms, enhancing durability and longevity in applications requiring frequent data updates. The hold pin allows communication to pause without resetting the device, increasing flexibility during system interrupts.

Suitable for industrial, commercial, and embedded electronics applications, the 25LC160B-I/MS EEPROM offers robust non-volatile memory with excellent retention, timing, and electrical characteristics. It complies with RoHS environmental standards.
