stm32f407ze vs. stm32f407ve - actual differences?

[CanisSomnolentus]

I looked at the pages for both MCUs side-by-side:

https://www.st.com/en/microcontrollers-microprocessors/stm32f407ze.html/

https://www.st.com/en/microcontrollers-microprocessors/stm32f407ve.html

I can detect no difference other than the Z vs. V in the name.

What are actual differences?

Doesn't the VE have 100-pins, and the ZE 144-pins ?

Same die, bonded out differently based on lead-frame

512KB FLASH tested (1MB on die)

D'OH! Yeah. I was fooled by looking at 2 almost identically looking 3rd party devboards, each with the other variant on it, but did not notice that difference. Thanks 😉

No worries it all blurs at some point.

The RE is the 64-pin 512KB variant, here the 'E' is the memory tested designator. The 1MB is the 'G'
