STM32F101X8_10 Datasheet, PDF (14/85 Pages) STMicroelectronics – Medium-density access line, ARM-based 32-bit MCU with 64 or 128 KB Flash, 6 timers, ADC and 7 communication interfaces

Description
STM32F101x8, STM32F101xB
2.2
Full compatibility throughout the family
The STM32F101xx is a complete family whose members are fully pin-to-pin, software and
feature compatible. In the reference manual, the STM32F101x4 and STM32F101x6 are
referred to as low-density devices, the STM32F101x8 and STM32F101xB are referred to as
medium-density devices, and the STM32F101xC, STM32F101xD and STM32F101xE are
referred to as high-density devices.
Low- and high-density devices are an extension of the STM32F101x8/B devices, they are
specified in the STM32F101x4/6 and STM32F101xC/D/E datasheets, respectively. Low-
density devices feature lower Flash memory and RAM capacities and a timer less. High-
density devices have higher Flash memory and RAM capacities, and additional peripherals
like FSMC and DAC, while remaining fully compatible with the other members of the
STM32F101xx family.
The STM32F101x4, STM32F101x6, STM32F101xC, STM32F101xD and STM32F101xE
are a drop-in replacement for the STM32F101x8/B medium-density devices, allowing the
user to try different memory densities and providing a greater degree of freedom during the
development cycle.
Moreover, the STM32F101xx performance line family is fully compatible with all existing
STM32F101xx access line and STM32F102xx USB access line devices.
