Product details
Overview
STM32F100VET6 from STMicroelectronics is a high-density value-line Arm® Cortex®-M3 MCU with 512 KB Flash, 32 KB SRAM, 24 MHz max CPU frequency, 12-bit ADC (16-channel), and dual 12-bit DACs-designed for cost-sensitive industrial control, motor drive feedback, and sensor interface applications requiring integrated analog peripherals and low-power operation.
For engineers reviewing the STM32F100VET6 datasheet, STM32F100VET6 pinout, STM32F100VET6 application, or STM32F100VET6 equivalent, key selection considerations include its LQFP100 package, 112 I/Os (5 V-tolerant), flexible static memory controller (FSMC) for external display/NOR flash, LCD parallel interface (8080/6800 modes), and full SWD/JTAG debug support.
Technical Context
The STM32F100VET6 implements an Arm Cortex-M3 core with single-cycle multiply and hardware divide, executing at up to 24 MHz (1.25 DMIPS/MHz). Its clock system integrates a 4–24 MHz external crystal oscillator, factory-trimmed 8 MHz RC, 40 kHz RC, PLL for CPU clock scaling, and dedicated 32 kHz RTC oscillator with calibration.
Peripheral architecture includes a 12-channel DMA controller servicing timers, ADC, SPI, I²C, USART, and DACs; nested vectored interrupt controller (NVIC) supporting 68 interrupts; and advanced timer subsystem comprising seven 16-bit general-purpose timers, one 16-bit advanced-control timer (6-channel PWM + dead-time + emergency stop), and two watchdogs.

FAQ
What is the maximum operating frequency of the STM32F100VET6?
The STM32F100VET6 operates at a maximum CPU frequency of 24 MHz, achieved via its internal PLL driven by the 4–24 MHz external crystal oscillator or factory-trimmed 8 MHz RC. This frequency is fixed by design to balance performance, power efficiency, and EMI compliance for value-line applications.
Does the STM32F100VET6 support USB or CAN interfaces?
No, the STM32F100VET6 does not include USB or CAN peripherals. It features up to 11 serial interfaces-including 3 USARTs, 2 UARTs, 3 SPIs, and 2 I²C ports-but lacks dedicated USB PHY or CAN transceiver blocks. For USB or CAN, engineers should consider the STM32F103 or STM32G0 series.
What is the purpose of the FSMC in this MCU?
The Flexible Static Memory Controller (FSMC) provides hardware timing control for external parallel memories and peripherals, supporting SRAM, PSRAM, NOR flash, and LCD modules in 8080/6800 modes. It eliminates software bit-banging overhead and enables direct framebuffer access for display applications.
How many analog-to-digital converter channels does the STM32F100VET6 have?
The STM32F100VET6 integrates one 12-bit ADC with up to 16 input channels, including dedicated connections for internal temperature sensor and VREFINT reference voltage. Conversion time is 1.2 µs per sample, and the ADC supports scan mode, injected channels, and DMA-triggered sequences.
