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 (I
2
C), Pulse Width Modulator, Multi-Function Timer, and Sync Signal Processor.
These features make it particularly suitable as a multi-sync computer monitor MCU.
The MC68HC05BD5 is functionally equivalent to MC68HC05BD3, with increase RAM and ROM.
The MC68HC705BD3 is an EPROM version of the MC68HC05BD5. All references to the
MC68HC05BD3 apply equally to the MC68HC705BD3 and MC68HC05BD5, unless otherwise
stated. References specific to the MC68HC705BD3 are italicized in the text and also, for quick
reference, they are summarized in Section 14. References to MC68HC05BD5 are summarized in
Section 15.
