INTRODUCTION

The Microchip Technology Inc. 93LC56/66 are low-power 3-wire non-volatile memories and are suitable for many embedded system code and data storage applications. These devices are easily interfaced to most microcontrollers in todays market place, but Microchip’s 8-bit RISC series PIC16CXX offers the best code density of any microcontroller on the market today. Using the PIC16C54, the assembly programs contained in this application note have been fully tested and provide the correct timing and 3-wire sequences to fully operate the 93LC56/66 in a PIC16CXX-based embedded application. The PIC16C54 was clocked at a 10MHz frequency. This application note is intended to provide the engineer with readily available stand-alone code modules to accomplish all of the necessary functions to utilize these devices in a low power application using the efficient PIC16C54 microcontroller.
