25LC640-E/SN Description

Short technical summary and product information.

The Microchip Technology 25LC640-E/SN is a 64 Kbit Serial Electrically Erasable PROM (EEPROM) that utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication. This device offers a memory organization of 8K x 8 bits and supports a maximum clock frequency of 3 MHz.

 

Key electrical characteristics include a typical write current of 3 mA, a typical read current of 500 μA, and a very low typical standby current of 500 nA. The operating voltage range is from 2.5V to 5.5V, and it supports an industrial temperature range of -40°C to +85°C, with the 'E' suffix indicating automotive temperature range up to 125°C.

 

Designed for reliability, the 25LC640-E/SN features data retention exceeding 200 years and ESD protection greater than 4000V. It includes built-in write protection mechanisms such as a write-protect pin and power on/off data protection circuitry. The device is available in an 8-pin SOIC package, suitable for surface mounting.

 

This EEPROM is well-suited for applications requiring non-volatile data storage in embedded systems where SPI communication is preferred. Its features make it a reliable choice for various industrial and automotive applications.
