The Microchip Technology 25C040T-E/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) accessed via a Serial Peripheral Interface (SPI) compatible serial bus. It features a memory organization of 512 x 8 bits and operates at a maximum clock frequency of 3 MHz.
This EEPROM is designed for a voltage range of 4.5V to 5.5V and has an operating temperature range of -40°C to 125°C. Key electrical characteristics include a write cycle time of 5ms, typical write current of 3 mA, typical read current of 500 μA, and a typical standby current of 500 nA. It offers high reliability with an endurance of 1M cycles and data retention exceeding 200 years.
The device is available in an 8-SOIC package, suitable for surface mount applications. It includes built-in write protection features such as a write-protect pin and a write enable latch, along with power on/off data protection circuitry. The SPI interface requires clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input. Communication can be paused using the HOLD pin.
