What this EEPROM brings to a mixed-voltage board
The AT34C02D-XHM-B is a 2Kbit serial EEPROM organized as 256 x 8 bits, accessed over an I²C bus at up to 1 MHz. The 1.7V to 5.5V supply span means it can sit on a 1.8V MCU rail or a 5V legacy bus without a level translator — one less component to qualify.
Package and interface fit for production
Housed in an 8-TSSOP (4.40 mm width) package, the AT34C02D-XHM-B uses a standard I²C two-wire interface — SDA and SCL — with a write-cycle time of 5 ms per word or page.
Lifecycle and compliance for BOM planning
It is ROHS3 compliant, which simplifies EU and global market compliance without requiring a waiver or exemption review.
