STM32, more choice with two complete lines

The Performance line, STM32F103, operates at 72 MHz,

with more on-chip RAM and peripherals. The Access

line, STM32F101, operates at 36 MHz. Both lines are

pin-to-pin and software-compatible, and offer the same

embedded Flash options.

The Performance line takes the 32-bit MCU world

to new levels of performance and energy efficiency.

With its Cortex-M3 core at 72 MHz, it is able to perform

high-end computation. Its peripheral set brings superior

control and connectivity.

The Access line is the entry point of the STM32 family.

It has the power of the 32-bit MCU but at a 16-bit MCU

cost. Its peripheral set offers excellent connectivity

and control.
