24LC32 4kx8 Microchip Serial EEPROM

Contents hide

The 24LC32B is a 32 Kbit Electrically Erasable PROM. The device is organized as four blocks of 256 x 32-bit memory with a 2-wire serial interface. Low voltage design permits operation down to 1.8V, with standby and active currents of only 1 uA and 1 mA, respectively. The 24LC32 also has a page write capability for up to 16 bytes of data. The 24LC32 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP 2×3 DFN, and MSOP packages, and is also available in the 5-lead SOT-23 package.
