MC68HC705P6A — Rev. 1.0

General Description

1.2 Introduction

The Motorola MC68HC705P6A is an EPROM version of the

MC68HC05P6 microcontroller. It is a low-cost combination of an

M68HC05 Family microprocessor with a 4-channel, 8-bit analog-to-

digital (A/D) converter, a 16-bit timer with output compare and input

capture, a serial communications port (SIOP), and a computer operating

properly (COP) watchdog timer. The HC05 CPU core contains 176 bytes

of RAM, 4672 bytes of user EPROM, 239 bytes of bootloader ROM, and

21 input/output (I/O) pins (20 bidirectional, 1 input-only). This device is

available in a 28-pin SOIC, PDIP, or windowed DIP package. A

functional block diagram of the MC68HC705P6A is shown in Figure 1-1.
