MSP430AFE221: looking for low cost MCU

Part Number: MSP430AFE221
Other Parts Discussed in Thread: MSPM0G1519

Tool/software:

Hello community,

We are designing a low-cost pump controller and are looking for an MCU with the following specifications:

White check mark MCU Requirements

  • Flash: 512 KB

  • RAM: 128 KB

  • GPIOs: 64 to 84

  • Integrated RTC

  • RTC cell support

  • No wireless connectivity needed

  • Lowest possible cost

If you have suggestions for a suitable MCU (from ST, TI, or others) that meets these requirements at a low price point, please share your recommendations.

Thanks in advance!
