Frequently asked questions
What is the difference between STM32F091CCU7TR and STM32F091RCT6?
The STM32F091RCT6 is the same core (ARM Cortex-M0 at 48 MHz) and same memory (256 KB Flash, 32K x 8 SRAM) but in a 64-pin LQFP package with more I/O. The STM32F091CCU7TR is a 48-UFQFN package with 38 I/O — they are not pin-compatible, so a board redesign is needed to swap between them.
What is the difference between STM32F091CCU7 and STM32F091CCU6?
The '7' grade is the wider industrial range.
