25LC640-I/P Description

Short technical summary and product information.

The Microchip Technology 25LC640-I/P is a 64 Kbit Serial Electrically Erasable PROM (EEPROM) utilizing low-power CMOS technology. It is accessed via a standard Serial Peripheral Interface (SPI) bus, requiring clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input.

 

This device features an 8192 x 8 bit organization and a 32-byte page size, with a maximum clock frequency of 2 MHz. It operates within a voltage range of 2.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical write current of 3 mA, a typical read current of 500 μA, and a standby current of 500 nA.

 

Designed for high reliability, the 25LC640-I/P offers data retention exceeding 200 years and ESD protection greater than 4000V. It includes built-in write protection features such as a write-enable latch and a write-protect pin, along with block write protection capabilities. The device is available in an 8-pin PDIP package, suitable for through-hole mounting.

 

This EEPROM is well-suited for applications requiring non-volatile data storage with a simple serial interface. Its features make it a reliable choice for various embedded systems where data integrity and low power consumption are important.
