Product details

With 114 general-purpose I/Os and a 24-channel 12-bit ADC plus a 2-channel 12-bit DAC, it is designed for advanced industrial control, human-machine interfaces (HMI), motor drives, and networked embedded systems that require real-time processing and mixed-signal acquisition.

Ethernet, CAN, and USB OTG — industrial networking ready

This MCU includes an Ethernet MAC (with MII/RMII interface), two CAN 2.0B controllers, and a USB OTG port with on-chip PHY. The Ethernet controller supports TCP/IP offload, while the CAN controllers handle real-time control messages without CPU intervention. The 180 MHz core and DMA engine keep packet processing overhead low.

Mixed-signal acquisition — 24-channel ADC and 2-channel DAC

The STM32F429ZIT6E packs a 24-channel 12-bit successive-approximation ADC and a separate 2-channel 12-bit DAC. For a motor-drive or sensor-fusion design, the ADC can sample multiple analog inputs (current sense, voltage, temperature) sequentially or in injected mode, while the DAC generates analog setpoints or reference voltages. The ADC conversion rate and resolution are sufficient for most industrial control loops without an external ADC.

Frequently asked questions

What is the difference between STM32F429ZIT6E and STM32F429ZIT6?

The STM32F429ZIT6E is the tray-pack variant of the base STM32F429ZIT6. The 'E' suffix typically denotes a specific packaging option (tray vs. tape-and-reel) or a minor revision. Functionally the two share the same core, memory, peripherals, and 144-LQFP package. For a BOM line, verify the preferred packing medium with your assembly house; the silicon is identical.

Can STM32F429ZIT6E be used for Ethernet applications?

Yes. The STM32F429ZIT6E includes an Ethernet MAC with MII and RMII interfaces, enabling 10/100 Mbps Ethernet connectivity. It requires an external PHY chip and magnetics, but the MAC is integrated, reducing BOM cost and board space for networked designs.

What is the closest pin-compatible alternative to STM32F429ZIT6E?

Within the STM32F429 series, the STM32F429ZIT6 (without the 'E' suffix) is pin-compatible and functionally identical, differing only in packing (tray vs. reel). For higher Flash or SRAM, the STM32F439 series offers 2 MB Flash and 256 KB SRAM with additional crypto/hash peripherals, but verify pin compatibility against the specific package variant.
