FAQ

What is the maximum operating frequency and core architecture of the STM32H730VBT6?

The STM32H730VBT6 features an Arm Cortex-M7 core with double-precision FPU, capable of running at up to 550 MHz. It includes 32 KB instruction and 32 KB data caches, enabling zero-wait-state execution from flash or external memory. The core achieves 2778 CoreMark and supports DSP instructions for signal processing workloads.

Does the STM32H730VBT6 support hardware cryptographic acceleration?

Yes, it integrates dedicated crypto peripherals including AES-128/192/256, TDES, HASH (MD5, SHA-1, SHA-2), HMAC, a true random number generator (RNG), and two OTFDEC engines for on-the-fly AES-128 decryption of Octo-SPI memory. These accelerate secure boot, encrypted firmware updates, and TLS stack operations without CPU overhead.

What package type and pin count does the STM32H730VBT6 use?

The STM32H730VBT6 uses a 100-pin LQFP package (14 × 14 mm, pitch 0.5 mm), designated as LQFP100 in ST's documentation. It provides 80 general-purpose I/O pins with interrupt capability, along with dedicated power, reset, clock, and debug signals. This package is ECOPACK2-compliant and rated for –40°C to +105°C operation.

How does the STM32H730VBT6 manage power efficiency in low-power modes?

It supports Sleep, Stop, and Standby modes with selective peripheral gating. Five low-power timers remain active in Stop mode for wake-up scheduling. The integrated SMPS (switched-mode power supply) replaces traditional LDOs, reducing quiescent current by up to 40% in active operation and enabling dynamic voltage scaling across performance states.
