Introduction

The MC68HC05PV8, MC68HC805PV8 and MC68HC05PV8A microcontrollers are members of Motorola’s 68HC05 family, designed for low-cost and single-chip systems in automotive applications. They combine an HC05 core with a shell of high-voltage peripherals. Throughout this book, the term MC68HC(8)05PV8/A is used to refer to all three MCUs.

The ROM (MC68HC05PV8) version of the MCU contains the HC05 CPU with integrated voltage regulator, RAM, ROM, EEPROM, core timer, COP watchdog, power-on reset, 16-bit programmable timer, PWM generator, standard parallel I/O, and special I/O for the automotive voltage range, including relay driver and contact monitors. Bootloader and test modes are supported. The package is 28-pin SOIC for the ROM and development version.

Features

Features of the MC68HC(8)05PV8/A include:
