Product details
Overview
STM32C071KBT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 128 KB flash, 24 KB SRAM, USB Full-Speed device interface (crystal-less), dual USARTs with LIN/IrDA support, and 12-bit ADC (0.4 µs conversion) for embedded control in industrial sensors and USB-connected peripherals.
For engineers reviewing the STM32C071KBT6 datasheet, STM32C071KBT6 pinout, STM32C071KBT6 application, or STM32C071KBT6 equivalent, key selection criteria include USB FS crystal-less operation, 5 V-tolerant I/Os, 48 MHz max CPU frequency, and support for Stop/Standby low-power modes with wake-up capability.
Technical Context
The STM32C071KBT6 integrates an Arm Cortex-M0+ core with MPU, hardware parity-checked SRAM, and securable flash memory. It supports multiple clock sources including 48 MHz HSI48 with clock recovery, 32 kHz LSE with calibration, and external 4–48 MHz crystal oscillator.
Peripheral interconnect is managed via AHB/APB buses with DMA controller (5 channels), flexible alternate function mapping across 61 GPIOs, and dedicated hardware blocks for USB FS, RTC with calendar, and advanced timer (TIM1) for motor control.

FAQ
Does STM32C071KBT6 support crystal-less USB Full-Speed operation?
Yes. The device integrates an HSI48 oscillator with clock recovery system, enabling compliant USB 2.0 Full-Speed device operation without an external 12 MHz crystal. This is confirmed in Section 3.9 and Table 41 of DS14693 Rev 2, and validated by USB-IF test reports for the C0 series.
What is the maximum operating temperature grade for STM32C071KBT6?
The STM32C071KBT6 is rated for −40°C to 125°C ambient operation, as specified in Section 3 and Table 24 of DS14693 Rev 2. This extended temperature grade supports deployment in harsh industrial environments including motor drives and outdoor sensor enclosures.
How many 5 V-tolerant I/O pins does STM32C071KBT6 have?
All 61 general-purpose I/O pins are 5 V-tolerant, per Section 3.10 and Table 51 of DS14693 Rev 2. This includes PA0–PA15, PB0–PB15, PC13–PC15, and PD0–PD2 - enabling direct interfacing with 5 V logic without external level-shifting circuitry.
Is the STM32C071KBT6 pin-compatible with other STM32C071 variants in LQFP48?
Yes. All STM32C071xB variants (including KBT6, RBT6, CBT6) share identical LQFP48 pinouts and electrical characteristics, as documented in Table 12 (Pin assignment and description) and Section 4 of DS14693 Rev 2. This allows drop-in replacement across flash/RAM configurations within the same package.
