MCU Proposal

[PLaw.1]

I am looking for STM32 series product for my Automotive Meter customer.

Required spec: 16KB/2KB, 16MHz, 2.7V to 5.5V, VQFN, -40°C to +125°C

Application: Automotive meter

I checked below ST link, and it seems that below links are OK (?) to meet above requirements?

Or do you have a better solution/proposal?

No, it does not.

The STM8 is a totally different architecture, and not related to Cortex M or STM32.

However, you are free to go for a STM8 instead, just take the software support (development, programming, debugging) into consideration.

Neither the STM8L series nor STM32 work with 5V supply voltage.

​Thanks for your good feedback, understand.

To original post said "2.7V to 5.5V", so I assumed the 3.3V of the STM32 are fine.

There are, however, Cortex M families that work with 5V, like the Fujitsu/Spansion/Cypress MB9 devices.
