Appendix A
MC68HC11D3 and MC68HC11D0
A.1 Introduction
The MC68HC11D3 and MC68HC11D0 are read-only memory (ROM) based high-performance
microcontrollers (MCU) 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 the ROM has been tested and guaranteed.
The information contained in this document applies to both the MC68HC11D3 and MC68HC11D0 with
the differences given in this appendix.
Features of the MC68HC11D3 and MC68HC11D0 include:
4 Kbytes of on-chip ROM (MC68HC11D3)
0 bytes of on-chip ROM (MC68HC11D0)
192 bytes of on-chip random-access memory (RAM) all saved during standby
16-bit timer system:
Three input capture (IC) channels
Four output compare (OC) channels
One IC or OC software-selectable channel
32 input/output (I/O) pins:
26 bidirectional I/O pins
3 input-only pins
3 output-only pins
Available in these packages:
44-pin plastic leaded chip carrier (PLCC)
44-pin quad flat pack (QFP)
