Adapt9S12E

Overview

Adapt9S12E is a compact, modular implementation of NXP's 9S12 E family-- utilizing the MC9S12E microcontroller chip. It is a member of the HCS12 family, and is backward-compatible with 68HC12 (and 68HC11). By shrinking feature size, more functionality can be put on a chip, reducing power consumption and cost, while increasing operating speed. Adapt9S12E is an ideal low-cost platform that brings these advantages within easy reach of engineers, students, and hobbyists. The flexible design of the entire Adapt series microcontroller products accommodates all aspects of training, evaluation, development, prototyping-- and even volume production.
