24AA256UID中文资料256Kb I2C Serial EEPROM with Pre-Programmed Serial Number数据手册Microchip规格书

描述 Description

The Microchip Technology Inc. 24AA256UID is a 256 Kbit Electrically Erasable PROM with a pre-programmed globally unique EUI-48™ and EUI-64™ IEEE MAC address. The device also has a pre-programmed 32-bit unique ID. This serial number is unique across all UID-Family of EEPROMs. The ID is Scalable to 48-bit, 64-bit, 128-bit, 256-bit, and other lengths. The 24AA256UID is a 32K x 8 (256 Kbit) SerialElectrically Erasable PROM, capable of operationacross a broad voltage range (1.8V to 5.5V). It hasbeen developed for advanced, low-power applicationssuch as personal communications or data acquisition.This device also has a page write capability of up to 64bytes of data. This device is capable of both randomand sequential reads up to the 256K boundary. The 24AA256UID device is avaliable in 8-SOIC, 8-PDIP and 8-TSSOP packages.
