Microchip Technology, Inc. Memory 25LC020A-E/ST

The 25LC020A-E/ST is a 2 Kbit Serial EEPROM from Lingto Electronic Limited, 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 includes built-in write protection mechanisms, such as a write-protect pin and power-on/off data protection circuitry. The device also supports self-timed erase and write cycles, with a maximum cycle time of 5 ms. The 25LC020A-E/ST is rated for high reliability, offering an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It is available in various package types, including 8-lead PDIP, SOIC, and TSSOP, making it suitable for a range of applications. The device is compliant with RoHS standards and is available in industrial and automotive temperature ranges, from -40¬8C to +85¬8C and -40¬8C to +125¬8C, respectively.
