diverse feature set.
The MCF51JM128 series is based on the V1 ColdFire core
and operates at processor core speeds up to 50.33 MHz. As
part of Freescale’s Controller Continuum
®
, it is an ideal
upgrade for designs based on the MC9S08JM60 series of 8-bit
microcontrollers.
The MCF51JM128 features the following functional units:
