Microchip Serial EEPROM Distributor | I2C and SPI Memory

BeiLuo supplies genuine Microchip serial EEPROM, the small non-volatile memory devices that store the configuration, the calibration, the parameters and the identity of an embedded board. A serial EEPROM uses a simple two-wire I2C bus or a four-wire SPI bus, so it takes few pins and a small package, and it keeps its data without power for decades, which makes it the standard choice for the settings that must survive a power cycle. Microchip offers the 24-series I2C and the 25-series SPI families from 128 bits to 512 Kbit, and the devices share a common pinout and a page-write architecture, so a design can move up in density within a family without a board change. The family includes the 24LC256 and 25LC256 at 256 Kbit and the 24AA02E48, a small I2C device that also carries a factory-programmed EUI-48 node identity, which suits a network device that needs a unique address. The endurance reaches about one million write cycles with a data retention of 40 years, and the devices operate over a broad voltage range and an industrial temperature range. Typical applications include configuration and parameter storage, calibration data, data logging, identity and serial-number storage and MAC-address storage. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the bus, the density and the package and plan the write protection and the layout.
