The AT25640A-10PU-1.8 is a 64Kbit EEPROM memory device that operates with a Serial Peripheral Interface (SPI) and supports SPI modes 0 and 3. It is designed for low-voltage operation, with a supply voltage range of 1.8V to 5.5V, and can achieve a clock rate of up to 20 MHz. The device features a self-timed write cycle with a maximum duration of 5 ms and offers high reliability with an endurance of one million write cycles and data retention of up to 100 years. The memory is available in various package types, including 8-lead PDIP, SOIC, TSSOP, and Ultra Thin Mini-MAP, making it suitable for a range of applications. It includes write protection features through a dedicated WP pin and block write protection options, allowing for enhanced data security. The operating temperature range is specified from -40¬8C to +85¬8C, making it suitable for industrial applications. However, it is noted that this part is not recommended for new designs.
