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:
