●The MC68HC908QB8 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
●Features include:
●• High-performance M68HC08 CPU core
●• Fully upward-compatible object code with M68HC05 Family
●• 5-V and 3-V operating voltages (VDD)
●• 8-MHz internal bus operation at 5 V, 4-MHz at 3 V
●• Trimmable internal oscillator
●– Software selectable 1 MHz, 2 MHz, or 3.2 MHz internal bus operation
●– 8-bit trim capability
●– ± 25% untrimmed
●– Trimmable to approximately 0.4%(1)
●• Software selectable crystal oscillator range, 32–100 kHz, 1–8 MHz, and 8–32 MHz
●• Software configurable input clock from either internal or external source
●• Auto wakeup from STOP capability using dedicated internal 32-kHz RC or bus clock source
●• On-chip in-application programmable FLASH memory
●– Internal program/erase voltage generation
●– Monitor ROM containing user callable program/erase routines
●– FLASH security
