Product details
Overview
STM32F070RBT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller with 128 KB flash, 16 KB SRAM, USB 2.0 Full-Speed interface, 11 timers (including one 16-bit advanced-control timer), and a 12-bit ADC-designed for cost-sensitive industrial control, smart sensors, and USB-connected peripherals operating at 2.4–3.6 V.
For engineers reviewing the STM32F070RBT6TR datasheet, STM32F070RBT6TR pinout, STM32F070RBT6TR application, or STM32F070RBT6TR equivalent, key selection criteria include USB FS integration, 51 I/Os with 5V tolerance, low-power Stop/Standby modes, and LQFP64 package compatibility for board-level routing and thermal management.
Technical Context
The device implements a single-core Arm Cortex-M0 CPU running up to 48 MHz, supported by an integrated PLL, dual clock sources (4–32 MHz HSE + 32 kHz LSE), and internal RC oscillators (8 MHz HSI, 40 kHz LSI). Its memory subsystem includes 128 KB of flash with error correction and 16 KB of SRAM with hardware parity checking.
Peripherals are tightly coupled via AHB/APB buses: the 12-bit ADC supports up to 16 channels with 1.0 µs conversion time and separate analog supply (VDDA = 2.4–3.6 V); USB 2.0 FS includes Battery Charging Detection (BCD) and Link Power Management (LPM); and seven 16-bit general-purpose timers provide input capture, output compare, and IR decoding capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables real-time deterministic control in compact firmware footprints. |
| Flash Memory | 128 KB - sufficient for USB stack + application logic + field-upgradable firmware images. |
| SRAM | 16 KB with HW parity - supports robust data buffering and interrupt-safe variable storage. |
| USB Interface | USB 2.0 Full-Speed with BCD/LPM - enables direct connection to host PCs without external PHY or charging negotiation ICs. |
| ADC | 12-bit, 1.0 µs conversion, 16-channel - suitable for precision sensor acquisition (e.g., temperature, current, voltage) with minimal external signal conditioning. |
| I/O Count & Tolerance | Up to 51 pins, 5V-tolerant - simplifies interface to legacy 5V logic, industrial sensors, and discrete actuators without level shifters. |
| Supply Voltage | 2.4–3.6 V (VDD), 2.4–3.6 V (VDDA) - compatible with single Li-ion battery or regulated 3.3 V rails in portable and embedded systems. |
Pinout & Package
LQFP64 (10 × 10 mm, 0.5 mm pitch) package with exposed thermal pad - optimized for thermal dissipation in continuous USB or PWM operation and compatible with standard PCB assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital power supply / ground | Primary 2.4–3.6 V domain; decoupling required per datasheet layout guidelines (DS10697 §7.4). |
| VDDA, VSSA | Analog power supply / ground | Independent 2.4–3.6 V rail for ADC/RTC; must be filtered and isolated from digital noise. |
| PA0–PA15, PB0–PB15, PC13–PC15, PD0–PD2 | General-purpose I/Os | 51 total GPIOs; all support external interrupts and 5V tolerance-enables direct interfacing to industrial I/O modules. |
| PA11/PA12 | USB DM/DP | Dedicated full-speed USB transceiver pins; require 1.5 kΩ pull-up on DP for device enumeration. |
| NRST | Active-low reset | Asynchronous reset input; supports external push-button or supervisor IC assertion with Schmitt-trigger input. |
| BOOT0 | Boot mode select | High at power-on forces system memory boot (for ISP via USART); tied low for normal flash execution. |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 FS with BCD/LPM | Eliminates need for external USB charger detection IC and reduces host-initiated suspend/resume latency in portable devices. |
| Calendar RTC with alarm & wakeup | Enables precise timekeeping and autonomous periodic wake-up from Stop/Standby modes-critical for battery-powered metering nodes. |
| 5-channel DMA controller | Offloads CPU during ADC sampling, SPI transfers, and memory-to-memory moves-reducing active power consumption and jitter. |
| Advanced-control timer (TIM1) | 6-channel complementary PWM with dead-time insertion-supports brushless DC motor control and digital power supply feedback loops. |
| Fast-mode Plus I²C (1 Mbit/s) | 20 mA sink capability allows direct drive of long bus traces or multiple slave devices without external pull-ups. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F070CBT6 | Same core/peripherals, but 128 KB flash in LQFP48 (48-pin) package - 3 fewer GPIOs, no USB D+/D− pins routed. | Preferred for space-constrained designs where USB is unnecessary and I/O count ≤ 39 suffices. | Select when board area is critical and USB connectivity is omitted; verify pin compatibility for existing LQFP48 footprint. |
| STM32F072RBT6 | Includes crystal-less USB calibration (HSE bypass), CRC unit, and additional security features (RCC clock security system). | Suitable for certified USB devices requiring clock robustness and tamper-resistant boot sequences. | Choose when USB timing stability across temperature/voltage is mandatory, or when production requires enhanced clock fault detection. |
Compared with STM32F070RBT6TR, STM32F070CBT6 trades USB and I/O count for smaller footprint, while STM32F072RBT6 adds USB clock resilience and security at marginally higher cost-making the RBT6TR optimal for USB-integrated cost-sensitive industrial endpoints.

FAQ
Does STM32F070RBT6TR support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 transceiver with internal pull-up resistor control on PA12 (DP), enabling enumeration on standard hosts using only a 1.5 kΩ pull-up on DP and proper VBUS sensing circuitry. No external PHY or USB connector IC is required.
What is the maximum allowed ADC input voltage range?
The ADC input voltage range is 0 to VDDA, with VDDA specified from 2.4 V to 3.6 V. Therefore, the absolute maximum measurable analog input is 3.6 V. Inputs exceeding VDDA risk damage or incorrect conversion; external clamping or scaling is required for signals above this threshold.
Can the STM32F070RBT6TR operate from a single 3.3 V supply without separate VDDA?
Yes. VDDA may be connected directly to VDD if the analog supply requirements are met (2.4–3.6 V), but ST recommends separate filtering and routing for VDDA to maintain ADC accuracy and reduce noise coupling-especially when measuring low-amplitude or high-resolution analog signals.
Is the LQFP64 package of STM32F070RBT6TR lead-free and RoHS compliant?
Yes. The STM32F070RBT6TR uses ST's ECOPACK2-compliant LQFP64 package, which is fully lead-free, halogen-free, and RoHS-compliant per Directive 2011/65/EU, with matte tin terminal finish and JEDEC-standard reflow profile compatibility.
