Product details

This is the high-density tier of the F4 line, sized for applications that need both compute throughput and a large firmware image — think motor-drive control loops with embedded EtherCAT stacks, or a display-centric HMI running a GUI library alongside real-time fieldbus communication.

Connectivity and peripherals — what the pin count buys you

For a board that needs to talk to a plant network, log data to an external SRAM or NAND Flash, and drive a local display, this part covers all three domains without glue logic.

The base product number is STM32F427, so PCN and errata tracking should be done against that root.

Frequently asked questions

What is the difference between STM32F427ZIT6TR and STM32F427ZIT6?

The STM32F427ZIT6TR is the Tape & Reel (TR) packaged variant of the STM32F427ZIT6. The silicon and the 144-LQFP package are identical; the suffix only changes the shipping medium for automated pick-and-place assembly.

Can the STM32F427ZIT6TR be programmed with ST-Link?

Yes. The STM32F427ZIT6TR uses the standard ARM Serial Wire Debug (SWD) interface, which is supported by all ST-Link programmers and debuggers. The SWD pins (SWDIO, SWCLK) are available on the 144-LQFP package.

What is the closest functional second-source to the STM32F427ZIT6TR?

The STM32L151CBU6A is a lower-power Cortex-M3 part from the STM32L1 series, but it runs at 32 MHz with 37 I/O and no Ethernet or external memory bus — it is not a pin-compatible or performance-equivalent replacement. For a true functional match within the STM32F4 family, look at the STM32F427VIT6 (100-pin LQFP) if you can reduce the I/O count, or the STM32F429ZIT6 which adds a TFT LCD controller in the same 144-pin footprint.
