25LC320-I/SN

The Microchip Technology 25LC320-I/SN is a 32 Kbit serial Electrically Erasable PROM (EEPROM) designed for efficient data storage. It utilizes a standard Serial Peripheral Interface (SPI) compatible serial bus for communication, requiring clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input.

This EEPROM features a 4K x 8 bit organization and a 32-byte page size, with a maximum write cycle time of 5 ms. It operates within a voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include low-power CMOS technology with a typical read current of 500 μA and a typical standby current of 500 nA.

Designed for high reliability, the 25LC320-I/SN offers an endurance of 1M write/erase cycles and data retention exceeding 200 years. It includes built-in write protection features such as power on/off data protection circuitry, a write enable latch, and a write-protect pin. The device is available in an 8-SOIC package, suitable for surface mount applications.

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