• Manufacturer Part Number: mc68hc05bs8
• Description: Mc68hc05 Family Of Low-cost Single-chip Microcontrollers.
• Manufacturer: Freescale Semiconductor, Inc

The MC68HC05BS8 HCMOS microcontroller is a member of the MC68HC05 Family of low-cost
single-chip microcontrollers. It is particularly suitable as a multi-sync computer monitor controller.
This 8-bit microcontroller unit (MCU) contains on-chip oscillator, CPU, RAM, ROM, EEPROM, I/O,
Timers, COP Watchdog, M-Bus Serial Interface System, PWM, and Sync Signal Processor.
The MC68HC705BS8 is an EPROM version of the MC68HC05BS8. All references to the
MC68HC05BS8 apply equally to the MC68HC705BS8, unless otherwise stated. References
specific to the MC68HC705BS8 are italicized in the text, and also, for quick reference, they are
summarized in Appendix A.
