Product details

180 MHz Cortex-M4 — throughput for display and control

The STM32F437IGH6 is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics, clocked at 180 MHz with 1 MB of Flash and 256 KB of SRAM. It carries a rich peripheral set including Ethernet, CAN, USB OTG, LCD controller, and multiple I²S and SPI interfaces, making it suited for HMI panels, industrial gateways, and motor-drive control boards where a single chip handles both the user interface and real-time fieldbus traffic.

1 MB of Flash is enough for a full graphics stack plus a Modbus or CANopen firmware image without external memory. The 256 KB SRAM supports double-buffered frame data for a small TFT display and still leaves headroom for communication stacks. With 140 I/O lines and interfaces for Ethernet, CAN, and USB OTG, this part can serve as the central node in a multi-protocol control network, reducing the need for separate bridge ICs.

EOL hot — sourcing reality for this BOM line

The lifecycle status for the STM32F437IGH6 is marked EOL hot, meaning the last-time-buy window is active and closing. If the design can accommodate a package or memory variant, qualifying a pin-compatible sibling within the STM32F437 family before the LTB closes is the lower-risk move.

Housed in a 176+25 UFBGA (10x10 mm) package, this MCU requires fine-pitch PCB routing and X-ray inspection for reliable solder joints.

Frequently asked questions

Is STM32F437IGH6 obsolete?

The STM32F437IGH6 is marked EOL hot, meaning the last-time-buy window is active. It is not yet discontinued but the phase-out is underway — order against an RFQ for current availability.

What is the maximum clock speed of STM32F437IGH6?

The core runs at 180 MHz, which is the maximum clock speed for this STM32F4 series device.

Is STM32F437IGH6 compatible with STM32F437VGT6?

Both parts share the same STM32F437 base product number and core architecture, but they differ in package and I/O count — the VGT6 uses an LQFP100 footprint while the IGH6 is a 176+25 UFBGA. Pin compatibility is not guaranteed without a layout review.
