The Microchip Technology AT25040A-W1-8-11 is a 4Kb serial EEPROM organized as 512 words by 8 bits. This CMOS device utilizes the SPI serial bus for communication, supporting synchronous operation up to 5MHz. It features a wide operating voltage range from 1.8V to 5.5V, with specific minimum and maximum supply voltages of 4.5V and 5.5V respectively, and a nominal 5V. Data retention is rated for a minimum of 100 years, with an endurance of 1,000,000 write cycles. The AT25040A offers both hardware and software write protection. This uncased chip package is suitable for applications in industrial control, consumer electronics, and automotive systems where non-volatile data storage is required. Standby current is a low 3.5µA, with a maximum supply current of 10mA.
