Microchip Technology's AT25040B-CUL-T is a 4Kb serial EEPROM organized as 512 words by 8 bits. This CMOS device operates via a SPI-compatible serial interface, supporting clock frequencies up to 5 MHz. It features a wide operating voltage range from 1.8V to 5.5V, with a nominal supply of 5V. Data retention is rated for a minimum of 100 years, and endurance is specified at 1 million write cycles. The AT25040B offers both hardware and software write protection capabilities. Its compact 8-ball VFBGA package (2x1.5mm, 0.5mm pitch) makes it suitable for space-constrained applications in consumer electronics, industrial automation, and automotive systems. This device operates within a temperature range of -40°C to +85°C.
