The Microchip 25AA040A/25LC040A is a 4 Kbit Serial EEPROM designed for use in a variety of applications requiring non-volatile memory. It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The memory is organized as 512 x 8 bits and features a write page mode that allows writing up to 16 bytes at a time. This EEPROM is suitable for industrial applications with a temperature range of -40¬8C to +85¬8C and offers high reliability with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It includes built-in write protection features, such as a write-protect pin and power-on/off data protection circuitry. The device is available in multiple package types, including 8-lead PDIP, SOIC, MSOP, TSSOP, DFN, and SOT-23, making it versatile for various design requirements. Engineers considering this EEPROM should note its low power consumption, with a maximum write current of 5 mA and standby current of 5 ¬µA, making it suitable for battery-operated devices.
