68HC805PV8 : Microcontroller

 

The MC68HC(8)05PV8 microcomputer is a member of Motorola’s 68HC05 family, designed for low-cost and single-chip systems in automotive applications. It combines an HC05 core with a shell of high-voltage peripherals. The ROM (MC68HC05PV8) version of the 8 bit microcomputer unit (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. In the flash-like development version (MC68HC805PV8), the ROM is replaced by a program EEPROM. The MC68HC(8)05PV8 is fabricated in a low-cost double-layer poly, single-layer metal, 40V, 1.2mm CMOS technology.
