The Serial EEPROM, 64Kbit, 20MHz, SOIC-8 is a memory device optimized for low-power and low-voltage applications. It features a memory size of 64Kbit organized as 8192 words of 8 bits each, and operates with a supply voltage range of 1.8V to 5.5V. The device supports a Serial Peripheral Interface (SPI) with a maximum clock frequency of 20MHz, and is compatible with SPI Modes 0 and 3. This EEPROM includes a 32-byte page mode for efficient data writing and offers block write protection, allowing users to protect portions of the memory array. It has a self-timed write cycle of up to 5ms and boasts a high endurance of 1,000,000 write cycles with a data retention period of 100 years. The device is available in various package options, including the space-saving 8-lead SOIC package.
