Product details

The 2 MB Flash (2M x 8) and 256K x 8 SRAM give enough room for a full Ethernet stack, a CANopen node, and a USB host stack without external memory. The 130 I/O lines in the 169-UFBGA package let you bring out the EBI/EMI bus for an external display or SRAM expansion while keeping sensor and actuator channels available.

Connectivity peripherals — single-chip gateway capability

That peripheral set lets a single STM32F427AIH6TR serve as a protocol gateway between an industrial Ethernet fieldbus, a CAN-based actuator network, and a USB-connected HMI — no external bridge chip needed.

169-UFBGA package — layout considerations

For designs that only need 80–100 signals, a 2-layer board with through-hole vias is feasible if the decoupling caps sit close to the BGA perimeter.

Frequently asked questions

What is the core of STM32F427AIH6TR?

The core is an ARM Cortex-M4 running at 180 MHz, with a 32-bit single-core architecture and hardware floating-point unit for DSP tasks.

What are the alternatives to STM32F427AIH6TR?

Within the STM32F4 family, pin-compatible alternatives exist across the density and package options — for example, the STM32F429 variant adds a TFT LCD controller but shares the same 169-UFBGA footprint. The exact alternative depends on whether you need the LCD controller or can trade Flash density for a lower-cost sibling.
