STM32F100 Microcontroller

 

STM32F100 Microcontroller Family

At first glance, it is not easy to understand how the STM32F100 range of microcontrollers from ST Microelectronics is arranged. This article explores the similarities and differences between members of the STM32F100 family.

 

STM32F100 microcontrollers are divided into 3 groups according to on-chip Flash memory size:

• Low density devices (16k Bytes or 32k Bytes Flash)
• Medium density devices (64k Bytes Flash or 128k Bytes Flash)
• High density devices (256k Bytes, 384k Bytes or 512k Bytes Flash)

Within each group, are the following parts:

Low Density Devices

STM32F100x4 – STM32F100C4, STM32F100R4

STM32F100x6 – STM32F100C6, STM32F100R6

Medium Density Devices

STM32F100x8 – STM32F100C8, STM32F100R8, STM32F100V8

STM32F100xB – STM32F100CB, STM32F100RB, STM32F100VB

High Density Devices

STM32F100xC – STM32F100RC, STM32F100VC, STM32F100ZC

STM32F100xD – STM32F100RD, STM32F100VD, STM32F100ZD

STM32F100xE – STM32F100RE, STM32F100VE, STM32F100ZE
