STMicroelectronics STM32G0B1KET6

Overview

STM32G0B1KET6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 512 KB Flash, 144 KB SRAM, dual 12-bit DACs, 12-channel DMA, and FDCAN/USB Type-C PD controllers - deployed in industrial motor control, smart metering, and USB-C power delivery systems requiring high integration and low-power operation.

For engineers reviewing the STM32G0B1KET6 datasheet, STM32G0B1KET6 pinout, STM32G0B1KET6 application, or STM32G0B1KET6 equivalent, key selection criteria include its 64 MHz CPU frequency, 94 fast I/Os (including 5 V-tolerant), dual FDCAN interfaces, crystal-less USB 2.0 FS device support, and -40°C to 125°C extended temperature grade.

Technical Context

This MCU integrates a single-core Arm Cortex-M0+ with MPU, supporting read-while-write flash with two banks and securable memory regions. Its clock system combines four oscillators (HSE, LSE, HSI16, HSI48) and a PLL for flexible timing across performance and ultra-low-power modes.

The peripheral interconnect uses a multi-layer AHB/APB bus matrix enabling concurrent access to ADC, DAC, timers, and communication interfaces. It features two independent FDCAN controllers compliant with ISO 11898-1:2015, USB 2.0 FS device/host with integrated PHY, and hardware-accelerated cryptographic services including AES-128 and SHA-256.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the STM32G0B1KET6?

The STM32G0B1KET6 operates at up to 64 MHz using its internal HSI16 oscillator with PLL multiplication or external HSE up to 48 MHz. This frequency is fully supported across the full -40°C to +125°C temperature range and all low-power modes except Shutdown, where clocks are gated.

Does the STM32G0B1KET6 support crystal-less USB operation?

Yes - the STM32G0B1KET6 integrates a factory-trimmed 48 MHz HSI48 RC oscillator with ±0.25% accuracy over temperature and voltage, enabling full-speed USB 2.0 device operation without an external crystal. This is validated per USB-IF test plan and documented in Section 3.24 of DS13560 Rev 6.

How many FDCAN interfaces does the STM32G0B1KET6 include?

The STM32G0B1KET6 includes two independent FDCAN controllers compliant with ISO 11898-1:2015, each with dedicated TX/RX pins (PD0/PD1 for FDCAN1, PD8/PD9 for FDCAN2), message RAM, and flexible filtering. Both support bit rates up to 5 Mbps and FD frame formats including ISO CAN FD and non-ISO CAN FD.

Is the STM32G0B1KET6 pin-compatible with other STM32G0B1 variants?

Yes - the STM32G0B1KET6 in LQFP64 (10 × 10 mm) is pin-compatible with all other STM32G0B1xEx devices in the same package, including STM32G0B1RET6 and STM32G0B1VET6. Pin assignments, alternate functions, and electrical characteristics are identical per Table 12 and Section 4 of DS13560 Rev 6.
