Product details

Connectivity and peripherals for HMI and industrial control

The peripheral set also features I²S audio interfaces, a built-in LCD parallel interface, and a full set of 24 12-bit ADC channels plus two 12-bit DACs. For a system architect, the Ethernet and CAN combination covers both factory-floor fieldbus and IP-based connectivity without an external controller chip.

The supply range of 1.8V to 3.6V allows operation from a single 3.3V rail or a dual 1.8V core / 3.3V I/O scheme, which simplifies power-tree design when the MCU shares a regulator with other 3.3V peripherals.

Frequently asked questions

What is the difference between STM32F439 and STM32F429?

The STM32F439 adds a hardware cryptographic accelerator and a true random number generator (TRNG) that the STM32F429 lacks. The core, memory, and peripheral sets are otherwise identical between the two.

Is STM32F439ZGT6 compatible with STM32F407?

The STM32F439ZGT6 is pin-compatible with the STM32F407 in the same 144-LQFP package, but the F439 adds the LCD parallel interface, Ethernet MAC, and cryptographic accelerator. Firmware and peripheral driver changes are required when migrating from the F407.
