Introduction

This application note provides details about the data retention and endurance (in other words, typical erase/write cycle number) of the integrated Non-Volatile Memories (NVM) for Microchip’s car access products:

• ATA5831, ATA5832, ATA5833, ATA8510, ATA8515, ATA8710
• ATA5781, ATA5782, ATA5785, ATA8210, ATA8215
• ATA5700, ATA5702

Each of these listed devices contains an AVR® 8-bit microcontroller, which is built using a modified Harvard architecture. This means the Flash program memory space is on a separate address bus than the Static RAM (SRAM).
