Advanced CMOS technology makes these devices ideal for low power Address nonvolatile memory applications. These devices also Counter have a Program Enable (PE) pin to allow the user to write-protect the entire contents of the memory array. The 93AA76/86 is available in standard 8-pin PDIP and Data Output DO 8-pin surface mount SOIC packages. Register Buffer DI Mode Decode PE Logic CS Clock CLK Generator 2004 Microchip Technology Inc.
