STM32H723VGH6 — STM32H723 — 550 MHz Cortex-M7, 1 MB Flash, 564 KB RAM, built-in USB HS PHY, FD-CAN by STMicroelectronics

The STM32H723VGH6 belongs to ST's STM32H72x Value Line — a streamlined Cortex-M7 family that strips non-essential autopilot peripherals (Ethernet MAC, DMA2D) to deliver maximum CPU performance at minimum cost. At 550 MHz, it is the fastest clocked MCU in the STM32 portfolio, specifically tuned for real-time control loops where every microsecond counts. The built-in USB 2.0 High-Speed PHY eliminates the external ULPI transceiver required by H743, reducing BOM cost and PCB complexity.

Product Overview

In the drone ecosystem, the STM32H723VGH6 is the High-end micro FCs, 550 MHz AIO, T-Motor H7 mini stacks. Betaflight 4.4+ H7 unified targets run at 8 kHz gyro / DShot 600 with RPM filtering, GPS Rescue 2.0, and HD OSD — all on a single MCU. With 80 GPIOs, 5× SPI, 5× I²C, 8 UARTs, and dual FD-CAN, it connects dual IMUs, ExpressLRS/Crossfire receivers, HDZero/Walksnail VTX, GPS, and SD-card blackbox simultaneously. It is the definitive F7 replacement for next-generation flight controller designs.

Key Features & Benefits

550 MHz ARM Cortex-M7 — The Fastest Clock in the H7 Lineup

At 550 MHz with hardware double-precision FPU (FPv5), the H723 delivers 15% higher raw clock speed than the H743 family — translating to faster gyro loop closure, lower IMU-to-motor-output latency, and headroom for next-generation 32 kHz+ PID loop rates. The Cortex-M7's 6-stage dual-issue superscalar pipeline exploits instruction-level parallelism for unmatched real-time control in the single-core MCU category.

1 MB Flash + 564 KB RAM — Optimized for Betaflight & ArduPilot

With 1 MB Flash and 564 KB SRAM, the H723 is purpose-built for flight controller firmware: Betaflight 4.4+ H7 targets fit with ample room for GPS Rescue, HD OSD fonts, and blackbox logging. ArduPilot runs with EKF3, terrain data, and Lua scripting — the sweet spot between F7 scarcity and H743 overkill for copter/plane platforms.

Built-in USB HS PHY — Direct 480 Mbps USB Configurator Connection

Unlike the H743 (which requires an external ULPI PHY for USB HS), the H723 integrates a built-in USB 2.0 High-Speed PHY on-chip. Betaflight Configurator and Mission Planner connect at 480 Mbps over a direct USB-C port — no external PHY IC, no EMI headaches, and firmware flashing completes in seconds instead of minutes.

Dual FD-CAN + 6× SPI + 5× I²C — Full Sensor Bus Without Compromise

Dual FD-CAN 2.0 controllers provide redundant DroneCAN buses for modular autopilot architectures. Six SPI interfaces (up to 100 MHz) connect dual IMUs, barometer, and OSD chip in quad-SPI mode simultaneously. Five I²C buses handle magnetometer, rangefinder, and optical-flow sensors without address conflicts.

3× 16-bit ADCs — True 16-bit Sensor Sampling

Three 16-bit successive-approximation ADCs (up to 5 MSPS) sample battery voltage, current-shunt, RSSI, and analog airspeed sensors at 16-bit resolution — critical for precision battery-fuel gauging and airspeed estimation in ArduPlane long-endurance missions.

80 GPIO, 8× UART, Dual SDIO — Compact but Capable

With 80 GPIOs, 8 UART/USART ports, and single SDIO interface, the H723 simultaneously runs dual GPS (UBlox + redundancy), ExpressLRS/Crossfire CRSF, SmartAudio/Tramp VTX control, MSP DisplayPort OSD, and high-speed SD-card logging — all in a footprint competitive with STM32F7 designs.

Target Applications

Betaflight 4.4+ H7 AIO & Stack Flight Controllers

The STM32H723 is rapidly becoming the go-to H7 MCU for Betaflight flight controllers — replacing F722 and F745 designs with 550 MHz headroom at F7-competitive pricing. Popular H723-based boards include the SpeedyBee F7/H7 hybrid stacks, JHEMCU H723 AIO, Diatone Mamba H7, and iFlight BLITZ H7 series. All run 8 kHz gyro / DShot 600 bidirectional with RPM filtering, GPS Rescue, and HD OSD without overclocking.

INAV Fixed-Wing & Long-Range Platforms

With 564 KB RAM, the H723 comfortably runs INAV's full navigation stack — including RTH (Return to Home), waypoint missions, terrain-aware altitude hold, and dual-compass sensor fusion — on fixed-wing FPV platforms. The built-in USB HS PHY enables rapid mission uploads from INAV Configurator, and dual FD-CAN supports DroneCAN GPS/airspeed peripherals.

ArduPilot Lightweight & Companion Platforms

With optimized ChibiOS builds, the H723 runs ArduPilot copter, plane, and rover firmware with EKF3, terrain database, and Lua scripting. It excels in companion-controller roles — bridging a primary autopilot (Cube Orange+) to auxiliary payloads (gimbal controllers, drop mechanisms, sensor pods) via dedicated UART and CAN buses while running a secondary MAVLink instance.

Micro & Whoop AIO Flight Controllers

The TFBGA-100 package's 8×8  mm footprint enables 25.5×25.5 mm AIO (all-in-one) boards integrating MCU, 4-in-1 ESC, OSD, and ExpressLRS receiver on a single PCB. The H723's 550 MHz clock lets whoop-class drones run full Betaflight 4.4+ with bidirectional DShot, dynamic idle, and crash-recovery at the lowest possible weight budget.

Racing Drone Competition FCs

At 550 MHz with hardware FPU, the H723 achieves the lowest IMU-to-motor-output latency in the single-core MCU class. MultiGP and DRL competition pilots benefit from sub-30 µs gyro-to-output latency, instant turtle-mode recovery, and failsafe redundancy that survives mid-race power spikes. The dual-bank Flash enables pit-lane firmware reflash between heats without external tools.

Educational & R&D Autopilot Development

The H723's balance of performance, peripheral count (80 GPIO, 8 UARTs, 5× SPI), and accessible TFBGA-100 package makes it the preferred MCU for university drone labs and startup autopilot prototyping. Supported by STM32CubeIDE, PlatformIO, and ArduPilot's waf build system, teams can go from concept to flight-ready PX4/ArduPilot build in under a week.

Frequently Asked Questions

Why choose STM32H723 over STM32H743 for a drone flight controller?

The H723 offers three key advantages for flight controller designs: (1) Higher clock — 550 MHz vs 480 MHz, giving 15% more headroom for gyro/PID loops. (2) Built-in USB HS PHY — eliminates the external ULPI PHY IC required by H743 for USB High-Speed, reducing BOM cost and board area. (3) Lower cost — the H723 omits Chrom-ART DMA2D (OSD acceleration) and Ethernet MAC, peripherals that are rarely used on Betaflight FCs. For pure flight controller applications, the H723 is the better value. Choose H743 if you need Ethernet, hardware OSD acceleration, or >1 MB Flash.

Can the STM32H723 run Betaflight 4.5+?

Yes. Betaflight 4.4+ H7 unified targets fully support the STM32H723. Flash using the STM32H723 target in Betaflight Configurator. With 550 MHz and 564 KB RAM, the H723 runs 8 kHz gyro loops with bidirectional DShot, RPM filtering, GPS Rescue, HD OSD, and Blackbox logging to SD card simultaneously. The 1 MB Flash variant (VGT6/VGH6) provides ample room; the 512 KB variant (VET6/VEH6) may require disabling optional features like GPS Rescue or HD OSD fonts for the largest builds.

Does the H723 support ArduPilot and PX4?

ArduPilot: Yes. The H723 is a fully supported ArduPilot target (ChibiOS HAL) for copter, plane, and rover. With 564 KB RAM, it runs EKF3, terrain following, and Lua scripting with careful feature selection. PX4: Limited. PX4's NuttX RTOS and uORB overhead push the H723's RAM budget; the H743 is officially recommended for PX4. For PX4 development, consider the H743 or H753.

How does the H723 compare to F722 and F745 for Betaflight?

The H723 delivers 2.5× the clock speed of the F722 (216 MHz → 550 MHz) and roughly 1.5× of the F745 (460 MHz → 550 MHz), while providing double-precision FPU (both F7s have single-precision only). The built-in USB HS PHY means faster firmware flashing and configuration access vs F7 designs that require external PHY or fall back to FS. For new Betaflight FC designs in 2025–2026, the H723 is the superior choice over any F7 variant.
