25C320T-I/SN

The Microchip Technology 25C320T-I/SN is a 32 Kbit serial Electrically Erasable PROM (EEPROM) that utilizes a standard Serial Peripheral Interface (SPI) compatible serial bus for communication. This device is designed for applications requiring non-volatile memory storage.

Key electrical specifications include a memory size of 32 Kbit, organized as 4K x 8 bits, with a maximum clock frequency of 3 MHz. It operates within a voltage range of 4.5V to 5.5V and features a write cycle time of 5 ms. The EEPROM technology ensures data retention for over 200 years with an endurance of 1M write/erase cycles. Low power consumption is achieved with a typical read current of 500 μA and a typical standby current of 500 nA.

This EEPROM is housed in an 8-SOIC package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). Built-in features include power-on/off data protection circuitry, a write enable latch, and a write-protect pin for enhanced data security. Sequential read operations are also supported.

The 25C320T-I/SN is a reliable choice for embedded systems needing persistent data storage. Its SPI interface simplifies integration with microcontrollers, making it suitable for various industrial and commercial applications.
