Data Sheet
36
The MC68HC908SR12 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08
Family is based on the customer-specified integrated circuit (CSIC)
design strategy. 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 of the MC68HC908SR12 include the following:
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
High-performance M68HC08 architecture
Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
Maximum internal bus frequency:
– 8-MHz at 5V operating voltage
– 4-MHz at 3V operating voltage
Clock input options:
– RC-oscillator
– 32kHz crystal-oscillator with 32MHz internal phase-lock-loop
12k-bytes user program FLASH memory with security
512 bytes of on-chip RAM
Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2)
with selectable input capture, output compare, and PWM
capability on each channel
Timebase module
3-channel, 8-bit high speed PWM (125kHz) with independent
counters and automatic phase control
Serial communications interface module (SCI)
