Application Note
A Look at the MC68HC908MR32 Motor Control Microcontroller
2
The MR32 is a new member of the low-cost, high-performance
M68HC08 (HC08) Family of 8-bit MCUs that are designed specifically for
midrange motor control applications.
The Motorola HC08 Family of MCUs is an enhanced, upward object
code compatible architecture that evolved from the M68HC05 (HC05)
Family. All MCUs in the family use the enhanced HC08 central
processor unit (CPU08) that includes new addressing modes, many new
instructions, and the performance improvements to existing instructions
that result from the introduction of instruction pipelining. MCUs in the
HC08 Family are available with a variety of package types, input/output
(I/O) modules, and various memory sizes and types.
Features of the MR32 motor control MCU include:
