STMicroelectronics STM32F101VDT6TR

Overview

STM32F101VDT6TR from STMicroelectronics is a high-density ARM® Cortex®-M3 32-bit microcontroller with 384 KB Flash, 48 KB SRAM, and 100-pin LQFP package. It delivers 36 MHz CPU frequency (1.25 DMIPS/MHz), integrates one 12-bit 1 µs ADC (16 channels), two 12-bit DACs, and supports up to 10 communication interfaces including 3× SPI, 2× I²C, and 5× USART. It is used in industrial HMI panels requiring integrated analog I/O, real-time control, and compact footprint.

For engineers reviewing the STM32F101VDT6TR datasheet, STM32F101VDT6TR pinout, STM32F101VDT6TR application, or STM32F101VDT6TR equivalent, key selection criteria include Flash/SRAM size, ADC/DAC resolution and speed, peripheral count (especially SPI/I²C/USART), LQFP100 package compatibility, and support for FSMC-based external memory expansion.

Technical Context

The STM32F101VDT6TR implements an ARM Cortex-M3 core with Harvard architecture, single-cycle multiplier, and hardware divide. Its clock system includes dual oscillators (4–16 MHz HSE + 32 kHz LSE), programmable PLL, and three internal RC sources (8 MHz HSI, 40 kHz LSI, calibrated 40 kHz RC).

Peripheral integration centers on deterministic real-time operation: nine timers (including four 16-bit general-purpose, two watchdogs, SysTick, and two DAC-driving basic timers), DMA with 12 channels servicing ADC, DAC, SPI, I²C, and USART, and flexible static memory controller (FSMC) supporting NOR/PSRAM/CompactFlash with 4 chip selects.

FAQ

What is the maximum operating frequency and associated performance metric of the STM32F101VDT6TR?

The STM32F101VDT6TR operates at a maximum CPU frequency of 36 MHz, delivering 1.25 DMIPS per MHz (45 DMIPS total) as measured by Dhrystone 2.1 benchmark. This performance level supports real-time execution of communication stacks (e.g., Modbus, CANopen), control algorithms, and GUI logic without external acceleration.

Does the STM32F101VDT6TR support external memory interfaces, and if so, what types and configurations are supported?

Yes, it integrates a Flexible Static Memory Controller (FSMC) with four chip select outputs. It supports asynchronous and synchronous modes for NOR Flash, PSRAM, NAND Flash, and CompactFlash, including multiplexed/non-multiplexed addressing and configurable read/write timings - enabling direct connection to external displays, data loggers, or FPGA co-processors.

How many analog-to-digital converter (ADC) channels does the STM32F101VDT6TR provide, and what is its conversion speed?

The device includes one 12-bit ADC with up to 16 input channels and a maximum conversion time of 1 µs (1 MSPS sample rate). It features built-in calibration, programmable sampling time per channel, and supports regular/injected conversion modes - suitable for multi-sensor acquisition in industrial monitoring systems.

Is the STM32F101VDT6TR pin-compatible with other members of the STM32F101 family, and what package variants share the same footprint?

Yes, all STM32F101xV parts (e.g., STM32F101VBT6, STM32F101VCT6, STM32F101VET6) use the identical LQFP100 (14 × 14 mm) package with 0.5 mm pitch. Pin functions are fully compatible across Flash sizes (128 KB to 512 KB), allowing hardware reuse and firmware scalability within the same PCB layout.
