STMicroelectronics M24256E-U
The M24256E-U is a 256-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K x 8 bits. It can operate with a supply voltage from 1.7 V to 5.5 V with a clock frequency up to 1 MHz, over an ambient temperature range from -40°C to +85°C. The device offers an 8-bit register called the configurable device address (CDA).| Part No. | M24256E-U |
