Standard DigiKey Search Filters/Criteria for ICs apply:
Whenever possible, we would do our best to never use FN packages.
We will minimize BGA packages use.
We choose parts not under EOL/Obsolete/Discontinued status.
View Prices At: Quantity 1
Marketplace Product: Exclude
Part Status: Active
Package / Case: NOT FN
Supplier Device Package: NOT FN

As explained in [[EEDEHD_ARM_Cortex_M7_MCU_choices]], choices for ARM Cortex M7 MCUs influence our choices of M4F MCUs. F stands for Floating Point calculation co-processor option that is built in. Without dedicated hardware, floating-point calculations are extremely inefficient and slow otherwise.

Note: only single-core solutions are looked at here, as being far less easier to start using for the first time by a newcomer, compared to multicore solutions.

Additional Search Criteria/Parameters:

Core Processor: ARM Cortex-M4/M4F. Note regarding also selecting M4 in addition to M4F: because just like in countless other situations, DigiKey search lists/criteria are to NEVER be trusted. They are too frequently incorrect, incomplete, stupid, or useless!!!

Due to our desire to be able to jump to M7 as needed, we will only support same three manufacturers that offer ARM Cortex M7 MCUs:

  • Microchip Technology
  • STMicrolectronics
  • NXP USA Inc.
