The Microchip Technology 25LC640-I/SN is a 64 Kbit Serial Electrically Erasable PROM (EEPROM) that utilizes a Serial Peripheral Interface (SPI) compatible serial bus. This device offers a memory organization of 8K x 8 bits with a 32-byte page size and a maximum clock frequency of 2 MHz. It operates within a voltage range of 2.5V to 5.5V and is rated for industrial temperature conditions, from -40°C to +85°C.
Key features include low-power CMOS technology with typical write current of 3 mA and read current of 500 μA. It also boasts high reliability with data retention exceeding 200 years and ESD protection greater than 4000V. The device supports block write protection and has built-in write protection mechanisms, including a write-protect pin.
Packaged in an 8-pin SOIC (0.154", 3.90mm Width) format, the 25LC640-I/SN is designed for surface mount applications. Its SPI interface requires clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input. A HOLD pin is available to pause communication.
