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:
| Microchip Technology | STMicroelectronics | NXP | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Family | Family | Family | Family | Family | Family | Family | Family | Family | Family | Family | |
| Family Name | SAM E54 | SAM E53 | SAM E51 | SAM D51 | STM32F3 | STM32F4 | STM32G4 | STM32L4 | STM32L4R | STM32L4S | |
| Largest non-BGA package | 128-TQFP | 128-TQFP | 128-TQFP | 128-TQFP | 208-LQFP | ||||||
| Largest BGA package | 120-TFBGA | 120-TFBGA | 120-TFBGA | 120-TFBGA | 216-TFBGA | ||||||
