Product details
Overview
STM32F101T6U6ATR from STMicroelectronics is a low-density ARM® Cortex®-M3 32-bit microcontroller with 32 KB Flash, 6 KB SRAM, 36 MHz max CPU frequency, 12-bit ADC (1 µs conversion), and 4 communication interfaces (I²C, 2×USART, SPI). It operates from 2.0–3.6 V and supports Sleep/Stop/Standby low-power modes, targeting compact industrial control and sensor interface applications.
For engineers reviewing the STM32F101T6U6ATR datasheet, STM32F101T6U6ATR pinout, STM32F101T6U6ATR application, or STM32F101T6U6ATR equivalent, key selection criteria include Flash/SRAM size, VFQFPN36 package compatibility, 51 I/O count with 5 V tolerance, RTC + temperature sensor integration, and SWD/JTAG debug support for embedded firmware development.
Technical Context
The STM32F101T6U6ATR implements an 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 integrates a 4–16 MHz external crystal oscillator, 8 MHz factory-trimmed internal RC, 40 kHz LSI RC, and a PLL for CPU clock generation.
Peripherals include a 12-bit, 1 µs ADC with up to 16 channels and integrated temperature sensor; five timers (two 16-bit general-purpose, two watchdogs, SysTick); and four serial interfaces - one I²C (SMBus/PMBus), two USARTs (with LIN/IrDA/ISO 7816), and one 18 Mbit/s SPI - all supported by a 7-channel DMA controller.

FAQ
What is the maximum operating frequency and associated power consumption of the STM32F101T6U6ATR?
The STM32F101T6U6ATR runs at up to 36 MHz with typical active current of 14 mA at 3.6 V and 36 MHz (code from Flash, peripherals enabled). At 8 MHz, current drops to ~5.5 mA. These values are measured per ST's DocID15058 Rev 6, Table 12 and Figure 12, under defined thermal conditions with proper decoupling.
Does the STM32F101T6U6ATR support USB or CAN interfaces?
No. The STM32F101T6U6ATR does not integrate USB or CAN peripherals. Its communication interfaces are limited to one I²C, two USARTs (with LIN/IrDA/ISO 7816), and one SPI. For CAN support, ST recommends the STM32F103xx series; USB requires STM32F105/107 or later families.
How many I/O pins are available, and which ones support external interrupts?
The STM32F101T6U6ATR provides 37 I/O pins across GPIO ports A, B, and C. All 37 pins can be configured as external interrupt sources via the EXTI controller, with 16 dedicated EXTI lines shared across ports - enabling flexible wake-up and event handling from any GPIO.
Is the VFQFPN36 package RoHS-compliant and lead-free?
Yes. The STM32F101T6U6ATR in VFQFPN36 packaging is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU. This is confirmed in ST's official ordering information (Table 50, DocID15058 Rev 6) and ECOPACK® environmental compliance documentation.
