STM32H750ZBT6 - 480MHz Cortex-M7 MCU 128KB Flash | STMicroelectronics
MPN: STM32H750ZBT6 ✓ AktifSTM32H750ZBT6 Ringkasan
A microcontroller (MCU) is an integrated circuit that combines a processor core, memory, and programmable peripherals on a single die. ARM Cortex-M7 cores add a six-stage superscalar pipeline, single-precision and double-precision floating-point unit (FPU), and tightly-coupled memory (TCM) for deterministic real-time response. The STM32H7 family sits at the high-performance tier of the STM32 portfolio, above Cortex-M4 parts (STM32F4) and below Cortex-A application processors. The H750 specifically trims Flash to 128 KB while retaining 1 MB SRAM, making it well-suited for code execution from external QSPI memory while keeping on-chip RAM for buffers and frame data.
Key features of the STM32H750ZBT6 include 480 MHz CPU clock, 1 MB SRAM, Chrom-ART graphics accelerator, hardware AES-256 / SHA-256 / TRNG, two SDMMC interfaces, an 8- to 14-bit camera interface, and up to 16-bit external memory bus for SRAM, PSRAM, NOR, NAND, and SDRAM. The LQFP-144 package exposes 114 GPIO across multiple 5V-tolerant banks and offers 16-bit ADC, comparators, op-amps, and 12-bit DAC peripherals.
The device is built on a 40 nm low-power CMOS process and supports four low-power modes (Sleep, Stop, Standby, VBAT) with RTC and backup registers retained in Standby. CoreMark performance reaches 1023 CoreMark at 480 MHz / 4.08 CoreMark/MHz. The dual-domain supply (Vcore plus VDD/VDDA) requires careful decoupling but enables dynamic voltage scaling to trade frequency for power consumption.
Typical applications include industrial motor control, human-machine interface (HMI) panels with TFT-LCD, audio processing with USB streaming, secure IoT gateways, drone flight controllers, and portable medical instrumentation. The 1 MB on-chip RAM is enough to run LVGL graphical stacks and audio buffers without external PSRAM, simplifying board layout.
When designing with this part, allocate a 4.7 µF bulk capacitor plus 100 nF decoupling per supply pin, follow ST's AN4661 PCB layout guide for high-speed signals, and reserve QSPI traces for short length-matched routing. The 128 KB internal Flash is often not enough for production firmware; use the Quad-SPI interface to boot XIP from an external Flash and treat internal Flash as a backup/bootloader region.

Aplikasi Biasa
STM32H750ZBT6 patut untuk 6 aplikasis: Industrial Motor Control (FOC / PFC), HMI / TFT-LCD Control Panels, Audio Processing / USB Streaming, Secure IoT Gateways / Edge Nodes, Drone Flight Controllers, Portable Medical Instrumentation.
Industrial Motor Control (FOC / PFC)
The STM32H750ZBT6 is a strong fit for industrial motor control because its 480 MHz Cortex-M7 with DSP instructions, three 16-bit ADCs at 3.6 MSPS, and advanced timer units (HRTIM, TIM1/TIM8) can execute field-oriented control and power-factor-correction loops within single-digit microsecond periods. The Chrom-ART accelerator is unused here, but the FPU accelerates Park/Clarke transforms and PI loops. Designers should consider the 128 KB internal Flash limit: production motor-control firmware often exceeds this size, so boot from external Quad-SPI Flash via XIP. The 144-LQFP industrial temperature range -40 °C to +85 °C supports factory-floor deployment. Companion parts: STGAP1AS gate driver, ACS712 current sensor, L6234 motor driver.

HMI / TFT-LCD Control Panels
For HMI applications driving a TFT-LCD panel with touch, the STM32H750ZBT6's Chrom-ART graphics accelerator and 1 MB SRAM enable 800x480 or smaller RGB displays with smooth GUI updates. The LTDC controller supports up to 1024x768 resolution in single-layer mode. The 1 MB internal RAM is enough for a double framebuffer plus LVGL heap without external PSRAM, which lowers BOM cost. Internal 128 KB Flash is insufficient for large UI assets, so designers typically boot from QSPI Flash and stream images on demand. The 144-LQFP package gives enough pins for parallel RGB and touch I2C. Companion parts: FT6336U touch controller, ILI9488 TFT driver, W25Q64JVSSIQ QSPI Flash.

Audio Processing / USB Streaming
Audio applications such as USB audio interfaces, guitar effect pedals, and intercom systems benefit from the STM32H750ZBT6's DSP extensions and double-precision FPU. The 1 MB SRAM can host a 16-second 48 kHz/24-bit circular buffer, and the SAI/I2S peripherals support sample rates up to 192 kHz. The USB OTG FS/HS block enables USB Audio Class 2.0 streaming at 480 Mbps. Hardware AES-256 also helps in audio encryption scenarios. The 144-LQFP industrial temperature range supports in-car audio use. The internal Flash limit again points designers to QSPI XIP for larger preset libraries. Companion parts: PCM5102APWR DAC, PCM1808PWR ADC, MAX98357AETE+T class-D amplifier.

Secure IoT Gateways / Edge Nodes
The STM32H750ZBT6 suits secure IoT edge gateways because of its integrated hardware AES-256, SHA-256, and true random number generator, which accelerate TLS handshake, secure boot, and over-the-air firmware update. The 480 MHz Cortex-M7 can run mbedTLS, LwIP, and an MQTT-SN stack concurrently. The 1 MB SRAM supports TLS session keys and an HTTP/2 frame buffer. The FMC interface can interface to external SDRAM for larger packet buffers, and two SDMMC blocks support Wi-Fi/BLE module cards. Companion parts: W5100 Ethernet controller, SN65HVD3082EDR RS-485, ATECC608B secure element.

Drone Flight Controllers
Drone flight controllers demand 1 kHz control loops with deterministic latency; the STM32H750ZBT6's 480 MHz core, tightly-coupled memory, and advanced timers meet this requirement when interrupt handlers are placed in ITCM. The Cortex-M7 DSP block accelerates IMU sensor fusion (Madgwick / Mahony filters). Three 16-bit ADCs sample battery current, ESC telemetry, and analog sensors concurrently. The hardware crypto block is useful for command-link authentication. The 128 KB internal Flash is enough for flight-control firmware; external Flash is reserved for logs and parameter storage. The 144-LQFP package offers enough pins for SPI-bus ESCs and UART GPS modules. Companion parts: MPU-6000 IMU, NEO-M8N GPS, MAX1480BEPI+ RS-422 link.

Portable Medical Instrumentation
Portable medical devices such as pulse oximeters, handheld ECGs, and point-of-care diagnostic readers benefit from the STM32H750ZBT6's DSP, large 1 MB SRAM for sample buffers, and 16-bit ADC precision. The Chrom-ART accelerator can drive a small color TFT for patient readouts without external GPU. The hardware AES-256 supports HIPAA-compliant data encryption. The 144-LQFP industrial -40 °C to +85 °C temperature range covers clinical environments. The 128 KB internal Flash is generally adequate for medical firmware with simple UI, and OTA updates can use external QSPI. Companion parts: ADS1292R ECG AFE, MAX30102 SpO2 sensor, ADG714BRUZ analog mux.

Catatan Desain
The STM32H750ZBT6 requires a multi-rail supply: VDD/VDDA at 1.62-3.6 V plus an internal Vcore regulator (set by VCAP pins) that needs a 2.2 µF + 100 nF cap pair on each VCAP pin. ST's AN4661 and the H7 reference manual RM0433 mandate four bulk 4.7 µF caps near the VDD pins and 100 nF per-pin ceramic decoupling. Failure to follow this decoupling plan results in brownout resets under high CPU load. Estimated: total decoupling budget is approximately 8 x 100 nF + 4 x 4.7 µF + 2 x 2.2 µF for proper operation.
Place a 4-layer PCB with continuous ground plane under the LQFP-144 footprint; high-speed signals like SDRAM clock, USB D+/D-, and SDMMC lines need 50 Ω controlled impedance and length matching within ±150 mil. Reference ST's AN4661 (STM32H7 PCB layout guide) for the recommended stackup and via stitching pattern. Keep the HSE crystal traces short and surrounded by ground guard ring to minimize jitter; long crystal traces can cause UART baud-rate errors and USB SOF jitter.
Do not rely on the 128 KB internal Flash for production firmware - most applications exceed this. Use the Quad-SPI interface in XIP mode to boot from an external W25Q Flash and reserve internal Flash for the bootloader. The H750 will not run the same firmware as the H753 without recompilation because Flash memory map differs. Also note: the H750 does not include the DSI Host controller, so MIPI-DSI displays are not supported - use LTDC + RGB for TFT panels.
The SDRAM interface (FMC) operates at up to 100 MHz; route address/command lines on inner layers with ground reference, and match clock-to-DQS skew within 50 ps. Use series 33 Ω resistors on SDRAM clock for source termination. The USB HS PHY pins (DP/DM) require 90 Ω differential impedance and a 5 V short-proof protection circuit (USBLC6-2SC6). Failing to meet USB-IF impedance compliance can cause enumeration failures and re-plug events.
