Product details

The STM32F429NIH7: The 216-ball TFBGA (13x13 mm) package keeps the footprint compact while routing all those signals.

168 I/O and a full connectivity suite — peripheral fit for system architects

With 168 I/O and peripherals like Ethernet, CAN, USB OTG, and an external bus interface, this MCU can serve as the main controller in a distributed automation node or a display-centric HMI. The 2 MB Flash leaves headroom for a TCP/IP stack, a GUI library, and application code without external memory in many cases. The 256K x 8 SRAM supports moderate frame buffers or data logging. The 12-bit ADC bank (24 channels) and dual 12-bit DACs handle analog sensor acquisition and control outputs directly.

Frequently asked questions

What is the difference between STM32F429NIH7 and STM32F429NIH6?

The primary difference is the temperature grade. Both share the same 216-TFBGA package, 180 MHz core, 2 MB Flash, and 256K x 8 RAM. The 'H7' variant is the better choice for environments that see sustained heat, such as enclosed motor drives or outdoor telecom cabinets.

Is STM32F429NIH7 RoHS compliant?

Yes. The STM32F429NIH7 is RoHS compliant by design, as standard for ST's STM32F4 series in TFBGA packaging. No exemption flags are noted on the product listing.
