Product details
Overview
STM32G0B1CBT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 128 KB Flash, 144 KB SRAM, dual 12-bit DACs, two FDCAN controllers, and USB Type-C™ Power Delivery support - deployed in industrial HMI, smart metering, and USB-C peripheral control systems.
For engineers reviewing the STM32G0B1CBT6TR datasheet, STM32G0B1CBT6TR pinout, STM32G0B1CBT6TR application, or STM32G0B1CBT6TR equivalent, key selection criteria include FDCAN timing compliance, USB-C PD controller integration, 125°C extended temperature operation, and dual DAC precision for analog feedback loops.
Technical Context
The device integrates an Arm Cortex-M0+ core running up to 64 MHz with MPU, dual FDCAN controllers supporting ISO 11898-1:2015, and a dedicated USB Type-C Power Delivery controller compliant with USB PD 3.0 specification - enabling autonomous port negotiation without external policy engine.
Its analog subsystem includes two rail-to-rail 12-bit DACs (0.4 µs settling), three programmable comparators, and a 12-bit ADC with hardware oversampling up to 16-bit resolution - all operating across the full 1.7–3.6 V supply range and qualified for 125°C ambient operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G0B1RBT6 | Same core/peripherals but LQFP64 package (64 pins), 512 KB Flash, no USB-C PD controller | Lacks integrated UCPD; requires external PD controller for USB-C negotiation | Select when higher Flash capacity and more GPIOs are needed, and USB-C PD is handled externally. |
| STM32G0C1RBT6 | Same 512 KB Flash, 144 KB SRAM, adds AES-256 crypto engine and PUF-based secure key storage | Includes hardware security features absent in G0B1; no USB-C PD controller | Choose for secure firmware distribution and encrypted communication where USB-C PD is not required. |
Compared with STM32G0B1CBT6TR, the STM32G0B1RBT6 trades USB-C PD integration for larger Flash and pin count, while the STM32G0C1RBT6 adds cryptographic acceleration at the expense of USB-C PD - making the G0B1CBT6TR uniquely suited for compact, self-contained USB-C peripheral designs requiring CAN FD and analog precision.
