The AT25010A/020A/040A series is a low-power, low-voltage version of the AT25010 series that provides 1024/2048/4096 bits of programmable read-only memory (EEPROM) organized as 128/256/512 words of 8 bits each. The series is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.
The AT25010A/AT25020A/AT25040A series provides 1 Kb, 2 Kb, or 4 Kb serial EEPROM memory in compact 8‑lead SOIC and TSSOP packages. The devices operate over a wide voltage range and support SPI modes 0 and 3, making them suitable for automotive and low‑power applications.
The document includes electrical characteristics, timing diagrams, pin configurations, instruction set details, and package dimensions, allowing designers to integrate the EEPROMs into their hardware and firmware designs.
