Product details
Overview
STM32F100RBH6BTR from STMicroelectronics is a low- to medium-density value-line ARM® Cortex®-M3 microcontroller with 128 KB Flash, 8 KB SRAM, 24 MHz max CPU frequency, 1×12-bit ADC (16-channel, 1.2 µs), and 2×12-bit DACs-used in industrial sensor nodes requiring real-time analog I/O and compact firmware execution.
For engineers reviewing the STM32F100RBH6BTR datasheet, STM32F100RBH6BTR pinout, STM32F100RBH6BTR application, or STM32F100RBH6BTR equivalent, key selection criteria include Flash/SRAM size, integrated DAC count, 5 V-tolerant GPIO support, RTC with VBAT backup, and LQFP64 package compatibility for cost-sensitive control designs.
Technical Context
The device implements an ARM Cortex-M3 core with single-cycle multiply and hardware divide, supporting deterministic real-time interrupt handling via NVIC and EXTI. Its clock system integrates dual oscillators (8 MHz HSI ±1%, 32.768 kHz LSE) plus PLL for flexible CPU and peripheral clock derivation.
DMA supports 7 channels across timers, ADC, SPI, I²C, USART, and DAC-enabling autonomous data movement without CPU intervention. The analog subsystem includes temperature-sensing capability and calibrated internal reference voltage for precision ADC/DAC operation across supply and temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F070F6P6 | ARM Cortex-M0, 48 MHz, 32 KB Flash, no DAC, 1×12-bit ADC (10-channel) | Lacks dual DAC and temperature sensor; lower interrupt latency but reduced analog feature set | Select when cost sensitivity outweighs need for DAC-based analog output or thermal monitoring |
| STM32F103C8T6 | Cortex-M3, 72 MHz, 64 KB Flash, 20 KB SRAM, no DAC, 2×12-bit ADC (16-channel) | Higher performance and memory, but no integrated DAC-requires external DAC for analog output | Choose when higher CPU throughput and larger code space are critical, and analog output is handled externally |
Compared with STM32F070F6P6, STM32F100RBH6BTR provides dual DACs and temperature sensing for analog-centric control; versus STM32F103C8T6, it trades CPU speed for integrated analog peripherals and lower active power-making it optimal for DAC-dependent, battery-aware applications.

FAQ
What is the maximum operating frequency and associated power consumption of STM32F100RBH6BTR?
The device operates up to 24 MHz with typical active current of 11.5 mA at 3.3 V and 24 MHz (code from Flash, peripherals enabled). At 8 MHz, active current drops to ~5.2 mA. These values are measured per datasheet Table 12 and validated across industrial temperature range (−40°C to +85°C).
Does STM32F100RBH6BTR support USB or Ethernet connectivity?
No. STM32F100RBH6BTR does not integrate USB PHY, MAC, or Ethernet controller. It supports only UART, SPI, I²C, and CEC interfaces. For USB host/device functionality, designers must add external transceivers or select higher-series STM32 parts (e.g., F105/F107 or F4xx families).
How many of the GPIO pins are 5 V-tolerant, and which ones are excluded?
Of the 51 GPIOs, all are 5 V-tolerant except PA13 (SWDIO), PA14 (SWCLK), and BOOT0. This tolerance allows direct interfacing with 5 V logic without level shifters-critical for legacy industrial I/O and sensor signal conditioning circuits.
What debug interfaces are supported, and what pins do they require?
It supports Serial Wire Debug (SWD) using PA13 (SWDIO) and PA14 (SWCLK), requiring only two pins. JTAG is also available but uses five pins (TMS, TCK, TDI, TDO, NRST). SWD is recommended for space-constrained designs and provides full programming, debugging, and real-time trace capabilities.
