Introduction

TODO see other page why M4F.

IC Selection

Selection criteria:

Only paying attention to Microchip Technology, STMicroelectronics, and NXP per TODO.

For low-end projects, will prefer non-FN, non-BGA packages, to significantly decrease project design cost, improve manufacturability, testability, repairability, and ability of CCA assembly without professional, precision, and high-cost equipment.

The following MCUs fit "low-end" criteria for our projects:
