Product details

The 2 MB of program Flash (2M x 8) and 256K x 8 of SRAM give enough headroom for a real-time operating system, a TCP/IP stack, and a local GUI frame buffer without external memory.

Connectivity and peripheral set — Ethernet, CAN, USB OTG on one die

This MCU carries Ethernet MAC, two CAN interfaces, USB OTG (host and device), plus a full complement of I2C, SPI, UART/USART, and I2S serial interfaces. The EBI/EMI bus can gluelessly connect to external SRAM, NOR Flash, or NAND Flash. For a system architect, this means a single STM32F429IIH6TR can serve as the main application processor handling Ethernet connectivity, CAN bus for industrial fieldbus, and a local display — no separate network coprocessor or graphics controller needed. The 140 general-purpose I/O lines in the 176+25 UFBGA package give plenty of pins for parallel buses and sensor arrays.

Package and layout — 176+25 UFBGA (10x10 mm)

For a BOM manager, this means no near-term last-time-buy risk and continued manufacturer support for new designs.

Frequently asked questions

What is the difference between STM32F429IIH6TR and STM32F429IIH6?

The STM32F429IIH6TR is the Tape & Reel (TR) packaged variant of the STM32F429IIH6. The die, the 176+25 UFBGA package, the 180 MHz speed, 2 MB Flash, and all peripherals are identical. The TR suffix only changes the shipping medium — Tape & Reel for pick-and-place machines versus tray or tube for the base part number. If your assembly line feeds from reels, order the TR variant; if you hand-place prototypes or use a tray feeder, the base STM32F429IIH6 works the same.

Does STM32F429IIH6TR have Ethernet and LCD support?

Yes. The STM32F429IIH6TR includes an Ethernet MAC peripheral and an integrated LCD controller with DMA support, as listed in the connectivity and peripherals set. This allows direct drive of parallel RGB LCD panels up to a certain resolution without an external display controller.
