The Microchip Technology 25LC040/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) accessed via a Serial Peripheral Interface (SPI) compatible serial bus. This device offers a memory organization of 512 x 8 bits and operates with a clock frequency of up to 2 MHz.
Key electrical characteristics include a supply voltage range of 2.5V to 5.5V, a write cycle time of 5 ms, and low power consumption with a standby current of 500 nA. The EEPROM features high reliability with an endurance of 1M cycles and data retention exceeding 200 years. It also includes built-in write protection mechanisms.
This component is housed in an 8-SOIC package suitable for surface mounting. The operating temperature range is specified as 0°C to 70°C (TA). The SPI interface requires clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input. A HOLD pin allows pausing communication, and a write-protect (WP) pin can disable write operations.
The 25LC040/SN is designed for applications requiring non-volatile data storage. Its SPI interface and compact 8-SOIC package make it suitable for integration into various embedded systems.
