DESCRIPTION

The Microchip Technology Inc. 24C08B/16B is an 8K or 16K bit Electrically Erasable PROM intended for use in extended/automotive temperature ranges. The device is organized as four or eight blocks of 256 x 8-bit memory with a 2-wire serial interface. The 24C08B/16B also has a page-write capability for up to 16 bytes of data. The 24C08B/16B is available in the standard 8-pin DIP and both 8-lead and 14-lead surface mount SOIC packages.
