Does this MCU work?

[modelkayak]

I was looking for an ARM based MCU to replace the TI MSP430. I'm assuming the main design constraint is the LCD voltage needs to be at 5V. As of April 2021, I noticed that NXP Kinetics line appears to be able to generate the 5V signal.

• K30 - https://www.nxp.com/docs/en/reference-manual/K30P64M72SF1RM.pdf
• K40 - https://www.nxp.com/docs/en/reference-manual/K40P64M72SF1RM.pdf

Would you agree that these MCUs would appear to work for this project? Thanks!

(Note: I wonder if the M0[+] line would be more power efficient, but they don't call out 5V support https://www.nxp.com/docs/en/reference-manual/KL33P64M48SF6RM.pdf)

The F-91W LCD glass works fine with 3V drive level, the MSP430 MCU doesn't support 5V LCD drive either.
