STMicroelectronics STM32F100VDT6

Overview

STM32F100VDT6 from STMicroelectronics is a high-density value-line Arm® Cortex®-M3 MCU with 384 KB Flash, 24 KB SRAM, 24 MHz max CPU frequency, 12-bit ADC (16-channel), and dual 12-bit DACs - deployed in industrial HMI controllers requiring real-time sensor acquisition and analog output control.

For engineers reviewing the STM32F100VDT6 datasheet, STM32F100VDT6 pinout, STM32F100VDT6 application, or STM32F100VDT6 equivalent, key selection criteria include Flash/SRAM capacity, LQFP100 package compatibility, integrated DAC/ADC precision, low-power Stop/Standby modes, and full peripheral remapping support for PCB layout flexibility.

Technical Context

The STM32F100VDT6 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 flexible static memory controller (FSMC) supporting SRAM, PSRAM, and NOR, LCD parallel interface (8080/6800 modes), 112 I/Os (5 V-tolerant on most), and 16 timers - including one advanced-control timer with 6-channel PWM, dead-time generation, and emergency stop for motor control.

FAQ

What is the maximum operating temperature range for STM32F100VDT6?

The STM32F100VDT6 is qualified for industrial temperature range: –40 °C to +85 °C. This rating is verified per JEDEC JESD47 and applies to all electrical specifications in the datasheet's Section 5.3.1, including Flash endurance (10k cycles) and ADC/DAC linearity over temperature.

Does STM32F100VDT6 support USB device functionality?

No, the STM32F100VDT6 does not include a USB peripheral. It offers up to 3 USARTs (with IrDA, LIN, and modem control), 2 UARTs, 3 SPIs, and 2 I²Cs - but no USB PHY or controller. For USB connectivity, designers must use external USB-to-UART bridges or migrate to STM32F103 or higher-series MCUs.

How many external interrupts can be assigned to GPIO pins on STM32F100VDT6?

All 80 GPIO pins on the LQFP100 package are mappable to 16 external interrupt lines (EXTI0–EXTI15), with each EXTI line capable of detecting rising/falling edges on any of up to 16 GPIOs sharing that line. This allows flexible event-driven design without dedicated interrupt pins per peripheral.

Is the internal 8 MHz RC oscillator factory-trimmed, and what is its accuracy?

Yes, the internal 8 MHz RC oscillator is factory-trimmed to ±1% accuracy at 25 °C and 3.3 V. Over the full industrial temperature range (–40 °C to +85 °C) and supply range (2.0–3.6 V), accuracy degrades to ±3%, as specified in Section 5.3.7 of DS5944 Rev 11 - sufficient for non-critical timing but not for UART baud rate generation without calibration.
