GENERAL DESCRIPTION
The MC68HC05BD3 HCMOS microcontroller is a member of the M68HC05 Family of low-cost single-chip microcontrollers. This 8-bit microcontroller unit (MCU) contains an on-chip oscillator, CPU, RAM, ROM, parallel I/O capability with pins programmable as input or output, M-Bus serial interface system (I2C), Pulse Width Modulator, Multi-Function Timer, and Sync Signal Processor. These features make it particularly suitable as a multi-sync computer monitor MCU.
