INTRODUCTION
TECHNICAL DATA
1-1
SECTION 1
INTRODUCTION
The MC68HC11D3 and MC68HC11D0 are ROM-based high-performance microcon-
trollers (MCUs) based on the MC68HC11E9 design. Members of the Dx series are de-
rived 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.
