Product details

216MHz Cortex-M7 with 2MB Flash — the headroom decision

The STM32F779NIH6TR: It carries 159 I/O lines, Ethernet MAC, USB OTG, a LCD parallel interface, QSPI, CAN, and LIN — enough peripheral set to serve as the main controller in an industrial HMI, a networked gateway, or a motor-drive control board without external bridge chips.

Memory budget for GUI and comms stacks

The 2MB Flash and 512KB RAM are the sizing tier that determines whether a design fits in this package or needs to step up to an external memory bus.

216-TFBGA — layout and assembly planning

The 216-TFBGA (13x13 mm) package requires a four-layer PCB minimum for fanout — the 159 I/O signals plus supply and ground need at least two signal layers under the ball array.

The tape-and-reel suffix (TR) is the standard shipping format for volume assembly — no reel-conversion step needed.

Frequently asked questions

What is the maximum clock speed of STM32F779NIH6TR and does it support Ethernet?

The STM32F779NIH6TR runs at a maximum core speed of 216MHz. It includes an Ethernet MAC interface (MII/RMII) plus USB OTG, so it can serve as a networked controller without an external Ethernet bridge chip.

What are the differences between STM32F779NIH6TR and STM32F779NIH6?

The STM32F779NIH6TR and STM32F779NIH6 are functionally identical — same 216MHz Cortex-M7 core, same 2MB Flash and 512KB RAM, same peripheral set. The difference is the shipping format: the TR suffix denotes Tape & Reel packaging for automated pick-and-place assembly, while the base part number ships in tray format. The silicon and package are the same 216-TFBGA device.
