24LC256

The 24LC256 is a Microchip 256 Kbit (32K x 8) serial electrically erasable PROM that communicates over the two-wire I2C bus, in an 8-pin package. It stores the configuration, the calibration and the parameters that must survive a power cycle without the cost or the size of a parallel memory, and its cascadable feature lets up to four devices share one bus for a larger total. The device uses a 64-byte page write with partial pages allowed and a self-timed write cycle of about five milliseconds, and it includes a Schmitt trigger and filtered inputs for noise suppression and a write-protect pin for hardware and software data protection. The endurance is about one million write cycles with a data retention of 40 years, which suits the settings that must last the life of the product, and the device operates from about 2.5 V to 5.5 V over an industrial temperature range. The broad voltage range and the small package make it a natural companion to a microcontroller, and the common pinout across the 24-series family lets a design move up in density without a board change. Typical applications include configuration and parameter storage, calibration data, data logging, identity 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 density and plan the write protection and the layout.
