Advanced CMOS Address technology makes these devices ideal for low power Counter nonvolatile memory applications. These devices also have a Program Enable (PE) pin to allow the user to write-protect the entire contents of the memory array. Data Output The 93LC76/86 is available in standard 8-pin PDIP and DO Register Buffer 8-pin surface mount SOIC packages. DI Mode Decode PE Logic CS Clock CLK Generator 2004 Microchip Technology Inc.
