DESCRIPTION
The Microchip Technology Inc. 85C72/82/92 is a 1K/
2K/4K bit Electrically Erasable PROM. The device is
organized as shown with a two wire serial interface.
Advanced CMOS technology allows a significant
reduction in power over NMOS serial devices. The
85C72/82/92 also has a page-write capability for up to
8 bytes of data (see chart). Up to eight 85C72/82/92s
may be connected to the two wire bus. The 85C72/82/
92 is available in standard 8-pin DIP and surface mount
SOIC packages.
