Product details
Overview
STM32G0B0KET6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 512 KB dual-bank Flash, 144 KB SRAM (128 KB with hardware parity), 6x USARTs, USB 2.0 FS host/device interface, and operation from 2.0–3.6 V. It delivers 64 MHz CPU performance in LQFP64 package for industrial control, smart sensors, and USB-connected edge nodes.
For engineers reviewing the STM32G0B0KET6 datasheet, STM32G0B0KET6 pinout, STM32G0B0KET6 application, or STM32G0B0KET6 equivalent, key selection factors include dual-bank Flash read-while-write capability, 93 fast I/Os with 5 V tolerance, 12-bit ADC with hardware oversampling up to 16-bit effective resolution, and integrated USB FS controller eliminating external PHY requirements.
Technical Context
The STM32G0B0KET6 integrates an Arm Cortex-M0+ core with Memory Protection Unit (MPU), supporting secure boot and memory isolation. Its clock system combines four oscillators - 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI (±1%), and 32 kHz LSI (±5%) - enabling precise RTC operation and low-power mode transitions.
Peripheral interconnect uses a multi-layer AHB/APB bus matrix with DMA controller (12 channels) and DMAMUX for flexible peripheral-to-memory routing. The analog subsystem includes calibrated temperature sensor, VREFINT, and VBAT monitoring - all accessible via the 12-bit ADC with 0.4 µs conversion time and 16 external channel support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G071KBT6 | Same Cortex-M0+ core, but 128 KB Flash, 36 KB SRAM, no USB host mode, fewer USARTs (4 vs 6) | Suitable for cost-sensitive single-interface devices; lacks USB host capability needed for peripheral enumeration. | Select when USB device-only operation suffices and Flash/SRAM budget is constrained. |
| STM32G0C1KET6 | Identical Flash/SRAM/USB specs, but adds AES-128 crypto accelerator and PUF-based secure key storage | Required for firmware signing, secure OTA, or HIPAA-compliant medical data encryption. | Choose when cryptographic services are mandatory; otherwise, STM32G0B0KET6 offers identical base functionality at lower BOM cost. |
Compared with STM32G071KBT6, the STM32G0B0KET6 provides 4× more Flash and full USB host/device flexibility; versus STM32G0C1KET6, it omits crypto hardware but retains identical timing, analog, and I/O performance - making it optimal for non-secure high-resource edge nodes.

FAQ
What is the maximum operating frequency and voltage range of the STM32G0B0KET6?
The STM32G0B0KET6 operates at up to 64 MHz CPU frequency across a supply voltage range of 2.0 V to 3.6 V. Its internal voltage regulator supports dynamic voltage scaling, and the 16 MHz HSI oscillator is factory-trimmed to ±1% accuracy - enabling reliable clocking without external crystal in many applications.
Does the STM32G0B0KET6 support USB device and host functionality simultaneously?
No - the integrated USB 2.0 Full-Speed controller supports device mode or host mode, but not simultaneous dual-role operation. Mode selection is configured at initialization via the USB_OTG_FS_GCCFG register; switching requires reinitialization and is not runtime-dynamic.
How many I/O pins are 5 V tolerant, and which packages support them?
Multiple I/Os are 5 V tolerant, including all pins in the LQFP64 package except USB DP/DM, NRST, and BOOT0. The exact count is 52 pins (PA0–PA15, PB0–PB15, PC0–PC15, PD2, PF0–PF1) - confirmed in Section 5.3.14 of DS13565 Rev 3. This tolerance applies identically across LQFP32/48/64/100 variants.
What debugging interfaces does the STM32G0B0KET6 provide?
The device supports Serial Wire Debug (SWD) via SWCLK and SWDIO pins (PA14/PA13), compliant with ARM CoreSight standards. It does not include JTAG support. SWD enables full breakpoint, watchpoint, and memory access capabilities using standard tools like ST-LINK/V2 or OpenOCD.
