Microchip authorized reseller I2C EEPROM 24AA256T-E-ST
24AA256T-E-ST
The EEPROM devices from Microchip Technology Incorporated feature non‑volatile data retention upon power‑loss and are capable of repeated erase‑and‑program operations. These devices cover densities ranging from 1 Kbits to 1 Mbits, supporting two mainstream interfaces: SPI and I²C. The SPI interface enables high‑speed data transfer with access controlled via chip‑select signal. The I²C interface operates over only two signal lines and supports 7‑bit slave address configuration, allowing up to 8 devices on one bus. This family of EEPROMs delivers a broad operating voltage range from 1.7 V to 5.5 V, industrial‑grade operating temperature of ‑40 ℃ to +85 ℃, single‑bit erase/write endurance of millions of cycles, and data retention of 200‑year at 25 ℃. Integrated write‑protection mechanisms prevent unintended erasure. Multiple RoHS‑compliant package options are available, including PDIP, SOIC, TSSOP, DFN and SOT‑63. These EEPROM components are widely deployed in industrial control and automation equipment for storing calibration parameters and operation logs; smart‑home and consumer‑electronic devices for saving personalized user configurations; as well as automotive electronics and on‑board units for retaining sensor calibration data and diagnostic trouble codes. They address diverse small‑volume data‑storage requirements across varied application scenarios.
