This wiki page a stash point for comparative notes on contemporary, cerca 2020 microcontroller families.  First comparisons looking at ARM Cortex-M0 and Cortex-M4 class parts.  Search may extend to other architectures, depending on low power abilities of parts and availabilities.

Processors from two families to investigate:

−
<ul>
 
−
<li> STM32F427/437 – serial audio interface, more performance and lower static power consumption<br />
 
−
<li> STM32F410 – New milestone in outstanding power efficiency (89 µA/MHz and 6 µA in Stop mode), true random number generator, low-power timer, and DAC.<br />
 
−
<li> STM32F413/F423 – Extends STM32F412 features with higher RAM and Flash memory density and an enhanced peripheral set including 10 UARTs, 3 CANs, SAI interface, a low-power timer, 2 DACs, 2 DFSDM with up to 6 filters. The STM32F423 includes AES encryption.<br />

Example
 
−
The following example shows how to map bit 2 of the byte located at SRAM1 address
 
−
0x20000300 to the alias region:
 
−
0x22006008 = 0x22000000 + (0x300*32) + (2*4)
 
−
Writing to address 0x22006008 has the same effect as a read-modify-write operation on bit
 
−
2 of the byte at SRAM1 address 0x20000300.
 
−
Reading address 0x22006008 returns the value (0x01 or 0x00) of bit 2 of the byte at SRAM1
 
−
address 0x20000300 (0x01: bit set; 0x00: bit reset).

Had heard of sixteen bit microcontrollers, but interesting to find that STMicro manufactures one.  There is only one such bit-width part on STMicro's site, and it is not recommended for new designs.  Link here:
