Product details

550 MHz Cortex-M7 — what it means for the BOM

The STMicroelectronics STM32H733ZGT6 is a single-core ARM Cortex-M7 MCU from the STM32H7 series, clocked at 550 MHz. That core speed, paired with 1 MB dual-bank Flash and 564 KB SRAM, targets applications needing real-time DSP or motor-control loops without stepping to a dual-core part. The 112 I/O and connectivity set — Ethernet MAC with MDIO, CAN, USB OTG, QSPI, multiple SPI and I²C — make it a fit for industrial gateways, PLC I/O modules, and motor-drive control boards where the processor handles both the control algorithm and the fieldbus stack.

Memory and peripheral allocation

The 1 MB Flash is dual-bank, which allows live firmware updates over Ethernet or CAN while the application continues running from the other bank. The 564 KB SRAM is split across multiple blocks — enough for a real-time OS heap plus several large DMA buffers. The 18-channel 16-bit ADC array and two 12-bit DACs handle multi-axis current sensing and analog output without external converters. Brown-out detect and POR are integrated, so the external supervisor can be a simple resistor-capacitor pair.

Supply range and temperature grade

Runs from 1.62 V to 3.6 V supply. The -40°C to 85°C industrial temperature range covers factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics without needing a mil-grade part. The 144-LQFP (20×20 mm) footprint is a standard hand-solderable QFP; no BGA reflow required for prototyping or low-volume production.

Frequently asked questions

Where can I buy STM32H733ZGT6 and what is the lead time?

The STM32H733ZGT6 is available to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ — no stock or lead-time figures are published here, but the part is actively sourced.

What is the closest pin-compatible alternative to STM32H733ZGT6?

Within the STM32H7 series, the STM32H742 and STM32H743 variants in the same 144-LQFP package share the same pinout and peripheral mapping, offering higher Flash or SRAM densities. A direct pin-compatible swap requires checking the specific memory and feature differences against the application firmware.

What is STM32H733ZGT6's core speed?

The ARM Cortex-M7 core runs at 550 MHz, which is the highest single-core clock in the STM32H7 value line and provides headroom for real-time control loops and DSP workloads.

What compliance documentation does ST provide for STM32H733ZGT6?

STMicroelectronics provides RoHS and REACH compliance declarations for this part. The 144-LQFP package is lead-free and halogen-free per ST's standard material disclosure. UL and IEC certifications are not listed on the component-level documentation.
