Product details
Overview
STM32F100C6T6B from STMicroelectronics is a 32-bit ARM® Cortex®-M3 microcontroller with 32 KB Flash, 4 KB SRAM, and 24 MHz CPU frequency, featuring integrated 12-bit ADC (16-channel), dual 12-bit DACs, seven DMA channels, and eight communication interfaces (including 2×I²C, 3×USART, 2×SPI, CEC). It targets cost-sensitive industrial control and sensor interface applications requiring low-power operation and real-time analog signal processing.
For engineers reviewing the STM32F100C6T6B datasheet, STM32F100C6T6B pinout, STM32F100C6T6B application, or STM32F100C6T6B equivalent, key selection considerations include its LQFP48 package, 5 V-tolerant I/Os (up to 37 pins), RTC with VBAT backup, SWD debug support, and 2.0–3.6 V supply range for embedded systems with mixed-voltage peripherals.
Technical Context
The device implements an ARM Cortex-M3 core with single-cycle multiplication and hardware division, delivering 1.25 DMIPS/MHz performance. Its clock system integrates a 4–24 MHz external crystal oscillator, factory-trimmed 8 MHz RC, 40 kHz RC, PLL for CPU clock generation, and dedicated 32 kHz RTC oscillator with calibration.
Peripheral architecture includes three 16-bit general-purpose timers (each supporting IC/OC/PWM), one advanced-control timer (6-channel PWM with dead-time generation), two basic timers for DAC triggering, independent/window watchdogs, SysTick, and full NVIC-based interrupt handling with up to 16 external interrupt vectors mapped across GPIO ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3, 24 MHz max - enables deterministic real-time execution with low-latency interrupt response for motor control and sensor fusion. |
| Memory | 32 KB Flash / 4 KB SRAM - sufficient for compact firmware with local data buffering and minimal external memory dependency. |
| Analog Peripherals | 1×12-bit ADC (1.2 µs, 16 ch) + 2×12-bit DACs - supports simultaneous analog acquisition and waveform generation in closed-loop systems. |
| Timers | 12 timers including 3×16-bit GP, 1×advanced-control, 2×basic - provides flexible PWM generation, input capture, and DAC synchronization without external timing ICs. |
| I/O Capability | 37 I/Os, 5 V-tolerant, mappable to 16 EXTI lines - simplifies interfacing with legacy 5 V logic and enables robust button/keypad scanning or encoder input. |
| Communication | 2×I²C, 3×USART (LIN/IrDA/ISO7816), 2×SPI (12 Mbit/s), CEC - covers industrial serial bus, smart-card, remote control, and consumer electronics protocols. |
| Power Management | Sleep/Stop/Standby modes + PVD + VBAT for RTC - extends battery life in portable instrumentation and enables time-stamped event logging during main power loss. |
Pinout & Package
LQFP48 package (7 × 7 mm, 0.5 mm pitch), 48-pin quad flat lead frame with exposed thermal pad - suitable for compact PCB layouts and cost-effective reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual 2.0–3.6 V supply rails with decoupling requirements per datasheet Section 5.3.6 - ensures stable core and I/O voltage under dynamic load. |
| NRST | Active-low reset input | Asynchronous reset with internal pull-up; accepts 5 V-tolerant logic - enables reliable power-on and watchdog-triggered recovery. |
| PA0–PA15, PB0–PB15, PC13–PC15 | General-purpose I/Os | 37 total 5 V-tolerant GPIOs; most support EXTI, AFIO remapping, and analog functions - allows flexible peripheral assignment and board-level routing optimization. |
| OSC_IN / OSC_OUT | External crystal oscillator terminals | Supports 4–24 MHz quartz crystals - provides precise clock source for USB-free timing-critical applications like motor commutation. |
| BOOT0 | Boot mode selection | High at reset selects system memory boot (for DFU); low selects user Flash - enables field firmware updates without debugger. |
| SWDIO / SWCLK | Serial Wire Debug interface | 2-pin debug port replacing JTAG - reduces PCB footprint and simplifies in-circuit programming and real-time tracing. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded CRC unit | Hardware-accelerated checksum calculation for firmware integrity verification and data packet validation in noisy industrial environments. |
| Temperature sensor | Integrated analog output calibrated against VREFINT - enables on-chip thermal monitoring without external components in fan control or battery management. |
| Programmable voltage detector (PVD) | Configurable threshold detection on VDD - triggers interrupt or reset before brown-out, protecting RAM contents and state machines during supply sag. |
| 96-bit unique ID | Factory-programmed serial number per die - supports secure device authentication, license binding, and traceability in OEM production. |
| Remap capability | AFIO register-controlled alternate function routing - resolves pin conflicts when multiple peripherals share same I/O (e.g., USART TX/RX vs. SPI MOSI/MISO). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F030F4P6 | ARM Cortex-M0, 16 KB Flash, no DAC, single 12-bit ADC (10 ch), no RTC calibration | Lacks VBAT-backed RTC and dual DACs - unsuitable for time-critical analog waveform generation or battery-backed logging | Select when cost is primary constraint and analog features are minimal; verify SWD debug compatibility with existing toolchain. |
| STM32G030F6P6 | Cortex-M0+, 64 KB Flash, 8 KB SRAM, no RTC oscillator input, no CEC, higher 64 MHz CPU | Higher performance but missing CEC and calibrated RTC oscillator - limits use in consumer IR ecosystems and precision timekeeping | Prefer for compute-intensive tasks where CEC/RTC calibration are unnecessary; note different pinout and bootloader behavior. |
Compared with STM32F100C6T6B, STM32F030F4P6 trades analog capability and RTC accuracy for lower BOM cost, while STM32G030F6P6 increases processing headroom at the expense of consumer IR and battery-backed timekeeping support - making the F100C6T6B optimal for balanced mixed-signal industrial edge nodes.

FAQ
Does STM32F100C6T6B support USB device functionality?
No. The STM32F100C6T6B does not include a USB peripheral or PHY. It lacks USB registers, dedicated USB clock domain, and required pin assignments. For USB-capable variants, consider STM32F103 or STM32F072 series. This device relies on USART, I²C, or SPI for host communication.
What is the maximum operating temperature range for STM32F100C6T6B?
The STM32F100C6T6B is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 5.3.1 of the datasheet (DocID16455 Rev 9, page 34), specifying ambient operating conditions under which all electrical characteristics remain valid.
Can the internal 8 MHz RC oscillator be used as the system clock source?
Yes. The factory-trimmed 8 MHz HSI RC oscillator can serve as the system clock source directly or feed the PLL. It achieves ±1% accuracy over temperature and voltage, sufficient for UART communication at 9600–115200 baud without external crystal - reducing BOM count in non-precision timing applications.
Is there hardware support for AES or cryptographic operations on this MCU?
No. The STM32F100C6T6B does not integrate hardware crypto accelerators (AES, SHA, PKA) or TRNG. Security functions must be implemented in software. For hardware cryptography, refer to STM32L4, STM32H7, or STM32WB series devices with dedicated crypto processors.
