The Microchip Technology 25LC640A-M/SN is a 64 Kbit Serial Electrically Erasable PROM (EEPROM) designed for efficient data storage. It utilizes a standard Serial Peripheral Interface (SPI) compatible serial bus, requiring clock (SCK), data in (SI), and data out (SO) lines for communication, controlled by a Chip Select (CS) input. This device supports a maximum clock frequency of 10 MHz and operates within a voltage range of 2.5V to 5.5V.
Key features include an 8192 x 8-bit organization with a 32-byte page size, enabling efficient data writes. It offers built-in write protection mechanisms, including a write-enable latch and a write-protect pin, along with power-on/off data protection circuitry. The EEPROM boasts high reliability with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It also provides robust ESD protection of over 4000V.
The 25LC640A-M/SN is specified for extended temperature ranges from -55°C to 125°C. It is supplied in an 8-lead SOIC package, suitable for surface mount applications. The low-power CMOS technology ensures minimal current consumption, with a maximum write current of 5 mA and a standby current of just 5 μA at 5.5V and 125°C.
