Programmer for Freescale 68HC(9)08

First steps in 8-bit development

Published in issue 364, April 2007

Freescale is one of the leaders in the microprocessor and microcontroller market, backing up its products with a very comprehensive range of support products and high-performance development tools. For the price of a 74xx TTL IC, there’s something to delight anyone nostalgic for the 68HC11. Here’s a programmer that lets you program Flash M68HC08 and 68HC908 family microcontrollers.
