Product details
Overview
STM32F101VDT6 from STMicroelectronics is a high-density access-line ARM® Cortex®-M3 microcontroller in LQFP100 package, featuring 384 KB Flash, 48 KB SRAM, 36 MHz max CPU frequency, 12-bit ADC with 16 channels, and dual 12-bit DACs. It integrates FSMC for NOR/PSRAM/CompactFlash support and operates across 2.0–3.6 V supply for industrial control panels requiring deterministic real-time response.
For engineers reviewing the STM32F101VDT6 datasheet, STM32F101VDT6 pinout, STM32F101VDT6 application, or STM32F101VDT6 equivalent, key selection criteria include Flash/SRAM capacity, peripheral count (9 timers, 10 communication interfaces), low-power mode behavior (Stop/Standby with RTC on VBAT), and LQFP100 pin compatibility within the STM32F101xD family.
Technical Context
The STM32F101VDT6 implements a tightly coupled ARM Cortex-M3 core with single-cycle multiplication and hardware division, executing at up to 36 MHz with 1.25 DMIPS/MHz performance. Its clock system combines four oscillator sources - 4–16 MHz HSE crystal, 8 MHz factory-trimmed HSI RC, 40 kHz LSI RC, and 32.768 kHz LSE - feeding a PLL for precise system timing.
Peripheral integration centers on deterministic real-time operation: nine timers include four 16-bit general-purpose units (each supporting IC/OC/PWM), two watchdogs (independent + window), SysTick, and two basic timers dedicated to DAC triggering. The 10 communication interfaces comprise up to 3 SPIs (18 Mbit/s), 2 I²C, 3 USARTs, and USB 2.0 full-speed (with internal PHY) - all mapped to fully remappable GPIOs with 5 V tolerance on most pins.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | Higher Flash (256 KB → 256 KB same; note: STM32F101VDT6 = 384 KB, so F103VCT6 has less Flash but adds USB OTG FS and higher ADC resolution (12-bit vs same), plus enhanced timer features (encoder interface, quadrature decoder). | F103 variant targets USB host/device applications and higher-precision motor control where encoder feedback is required. | Select F103VCT6 only if USB OTG host capability or advanced timer functions (e.g., complementary PWM with dead-time insertion) are mandatory - otherwise F101VDT6 offers superior Flash headroom and lower cost. |
| STM32F072VBT6 | Cortex-M0 core, 48 MHz max, 128 KB Flash, 16 KB SRAM, no FSMC, no DAC, fewer timers (7), USB 2.0 FS only (no crystal-less mode), lower peripheral count. | Suitable for cost-sensitive, lower-complexity control tasks (e.g., simple lighting controllers or fan speed regulators) without memory-mapped display or dual DAC needs. | Choose F072VBT6 when BOM cost reduction is primary and application fits within 128 KB Flash/16 KB SRAM - not suitable for FSMC-based displays or dual analog output systems. |
Compared with STM32F103VCT6, the STM32F101VDT6 provides 50% more Flash (384 KB vs 256 KB) and integrated FSMC for display/storage expansion, while lacking USB OTG host support; versus STM32F072VBT6, it delivers 3× more SRAM and dual DACs essential for closed-loop analog control, at higher power and cost.

FAQ
What is the maximum operating frequency and associated power consumption of the STM32F101VDT6?
The STM32F101VDT6 operates at up to 36 MHz with typical active-mode current of 28 mA at 3.6 V (code from Flash, all peripherals enabled). At 8 MHz, consumption drops to ~10 mA under identical conditions. These values are measured per STMicroelectronics DocID14610 Rev 9, Tables 14–19, and assume proper decoupling and ambient temperature of 25°C.
Does the STM32F101VDT6 support USB device functionality without an external PHY?
Yes - the STM32F101VDT6 integrates a full-speed USB 2.0 device controller with an internal transceiver, eliminating the need for an external PHY. It supports control, interrupt, bulk, and isochronous transfer types and is certified compliant with USB-IF test specifications when used with the ST-provided USB library and correct PCB layout (e.g., 90 Ω differential impedance).
How many GPIO pins are 5 V-tolerant, and which ones are excluded?
Of the 80 GPIO pins, all are 5 V-tolerant except those assigned to ADC inputs (e.g., PA0–PA7, PB0–PB1, PC0–PC5), oscillator inputs (OSC_IN, OSC_OUT), and BOOT0. This is confirmed in Section 2.3.21 (GPIOs) and Table 46 (I/O static characteristics) of the datasheet, enabling safe interfacing with 5 V logic in mixed-signal industrial systems.
What is the purpose and electrical specification of the VBAT pin?
The VBAT pin supplies backup power to the RTC and 4 KB of backup SRAM during main power loss. It accepts 1.8–3.6 V and draws ≤1 µA in standby (typ.). When powered, it maintains RTC calendar/time and retains register contents across VDD removal - verified in Section 2.3.16 and Table 17 of the official datasheet.
