Microchip Technology, Inc. Memory 25LC020AT-E/ST

The 25LC020AT-E/ST is a 2 Kbit Serial EEPROM from Quarktwin Technology Ltd., designed for use with a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz. The memory is organized as 256 x 8 bits and features a write page mode that allows writing up to 16 bytes at a time. This EEPROM is characterized by low power consumption, with a maximum write current of 5 mA and a standby current of just 5 ¬µA. It offers high reliability with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. The device includes built-in write protection features, such as a write-protect pin and power-on/off data protection circuitry. The 25LC020AT-E/ST is available in various package types, including 8-lead TSSOP, making it suitable for a range of applications, including industrial and automotive environments, with operating temperature ranges from -40¬8C to +125¬8C.
