STM32G071CBT6 Cortex-M0+ MCU for Iceriver BP-H-3640 PSU Repair
Boost the performance of your embedded systems with the STM32G071CBT6 microcontroller — a high-performance MCU powered by the Arm Cortex-M0+ 32-bit RISC core running up to 64 MHz. With its integrated Memory Protection Unit (MPU), extensive system features, and enhanced I/O / peripherals, this microcontroller offers exceptional capabilities. Compatible with the cryptominer Iceriver BP-H-3640 PSU — drop-in replacement for failed MCU on the PSU control board.
Features up to 128 KB Flash program memory with read protection and proprietary code protection — securing your firmware. 36 KB SRAM (32 KB with HW parity check) provides ample memory for data storage and processing. The MCU also includes a 12-bit ADC with up to 19 channels, two 12-bit DACs, fast comparators, timers, and a low-power RTC for full embedded system functionality.
Typical Use in Iceriver PSU Repair
- BP-H-3640 PSU control board MCU failure — drop-in replacement for failed STM32G071CBT6.
- PSU boot failure recovery — restoring control board boot after MCU damage.
- General Cortex-M0+ applications — embedded designs needing 64 MHz performance.
- Industrial control / instrumentation — wide operating temperature range supports industrial use.

FAQ — STM32G071CBT6 MCU
Q: Do I need to flash firmware after MCU replacement?
A: Yes — new STM32G071CBT6 ships blank. After installation, flash the BP-H-3640 PSU control board firmware via SWD / ST-Link or matching production programmer. Source firmware from board-revision-matched repair documentation.
Q: How do I diagnose a failed MCU on PSU control board?
A: Typical signs: PSU control board fails to boot, no UART / I²C activity, no PWM output to power stage, control LEDs dead despite VDD present. Test by checking VDD (3.3V) at the MCU power pins — if VDD is present but no boot, MCU is likely failed.
Q: Can I substitute STM32G071RBT6 or other variants?
A: Different package (RB = LQFP-64 vs CB = LQFP-48). Don't substitute — the PCB footprint won't match. For OEM-spec repair, stick with STM32G071CBT6.
Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your volume for tier pricing on STM32G071CBT6 stock.
