25LC040T-I/SN

The Microchip Technology 25LC040T-I/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) with a memory organization of 512 x 8 bits. It utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication, requiring SCK, SI, and SO lines, and is controlled via a Chip Select (CS) input. This device supports a maximum clock frequency of 2 MHz and operates within a voltage range of 2.5V to 5.5V.

Key features include a write cycle time of 5ms, self-timed erase and write cycles, and block write protection capabilities. The EEPROM offers high reliability with an endurance of 1M cycles and data retention exceeding 200 years. It also provides built-in write protection mechanisms, including power on/off data protection circuitry, a write enable latch, and a write-protect pin.

This component is housed in an 8-pin SOIC package and is designed for surface mounting. It operates within an industrial temperature range of -40°C to +85°C. The device is suitable for applications requiring non-volatile data storage with a low-power CMOS technology, featuring typical read current of 500 μA and standby current of 500 nA.
