25LC128-I/P Description

Short technical summary and product information.

The 25LC128-I/P is a 128Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology, designed for applications requiring non-volatile data storage with byte-level erase and write capability.

 

This device communicates via the Serial Peripheral Interface (SPI) bus and supports clock frequencies up to 10MHz, enabling fast read and write operations. It operates across a supply voltage range of 2.5V to 5.5V, making it suitable for both 3.3V and 5V systems. The memory is organized as 16,384 x 8 bits (128Kbit).

 

The 25LC128-I/P is housed in an 8-lead PDIP (Plastic Dual In-line Package) with a 0.300 inch body width, suitable for through-hole mounting on PCBs or breadboards. It is commonly used in embedded systems, industrial controls, automotive electronics, and consumer devices for configuration storage, calibration data logging, and firmware updates.
