MC68HC11A1FN Datasheet PDF - Freescale

INTRODUCTION

●The MC68HC11D3 and MC68HC11D0 are ROM-based high-performance microcontrollers (MCUs) based on the MC68HC11E9 design. Members of the Dx series are derived from the same mask and feature a high speed multiplexed bus capable of running at up to 3 MHz, and a fully static design that allows operations at frequencies to dc.

●The only difference between the MCUs in the Dx series is whether or not the ROM has been tested and guaranteed.
