Product details

The STM32F429BIT7: This part is aimed at applications that need a single-chip compute engine with rich connectivity — think industrial PLCs, motor drives with display HMIs, and IoT gateways that must juggle Ethernet, CAN, and USB OTG simultaneously.

168 I/O and peripheral set — what fits on the board

With 168 general-purpose I/O and an integrated LCD controller, this MCU can drive a color TFT panel directly while managing a fieldbus network stack. The 24-channel 12-bit ADC and 2-channel 12-bit DAC cover analog sensor acquisition and control outputs without external converters.

The 208-LQFP package (28x28 mm) is a standard fine-pitch QFP that reflows with conventional lead-free profiles and is inspectable under AOI — no X-ray needed. The 168 I/O are all 5 V-tolerant on the digital pins, simplifying level translation when interfacing to legacy 5 V peripherals.

The STM32F4 series has broad ecosystem support, so second-sourcing across density and package variants within the family is straightforward without a PCB respin.

Frequently asked questions

What is the equivalent or replacement for STM32F429BIT7?

The STM32F429BIT7 is part of the STM32F4 series. For a lower-power, lower-performance alternative, the STM32L151CBU6A (Cortex-M3, 32 MHz, 32 KB Flash) is a different class of device and not a direct pin-compatible replacement. Within the STM32F4 family, density and package variants share the same core architecture and peripheral set, allowing a software-compatible migration without a PCB change.

Does STM32F429BIT7 fit into existing STM32F4 designs?

Yes. The STM32F429BIT7 is pin-compatible with other STM32F4 devices in the 208-LQFP package. The same PCB footprint and supply rails work; firmware may need minor adjustments for Flash and RAM size differences. The 180 MHz core and 2 MB Flash are at the high end of the series, so existing designs with lower-density F4 parts can drop in this part for extra headroom.
