Product details

The STM32F437ZIT7TR: ARM Cortex-M4 core with single-precision FPU and DSP instruction set at 180 MHz. 2 MB Flash and 256 KB RAM support LCD controller, Ethernet, and USB OTG.

Temperature range and package — rework and environment

144-LQFP (20×20 mm) package.

Listed as Active by STMicroelectronics. No last-time-buy notice, no end-of-life announcement.

Peripheral set — what connects where

Brown-out detect, POR, PWM timers, and a watchdog are on-chip. 114 I/O pins in the 144-LQFP give you enough GPIO for a parallel LCD data bus plus a handful of sensors and actuators.

Frequently asked questions

What is the maximum operating frequency of STM32F437ZIT7TR?

180 MHz, from the ARM Cortex-M4 core with FPU. That's the top speed for the STM32F437 series; lower STM32F4 parts (e.g., STM32F405) top out at 168 MHz.

Can I replace STM32F437ZIT7TR with STM32F437ZIT7?

The order codes differ only by the 'TR' suffix, which indicates tape-and-reel packaging. The STM32F437ZIT7 (without TR) is the same silicon in the same 144-LQFP package, shipped in tray or tube. They are electrically identical and footprint-compatible. The TR suffix is purely a packaging code — if your pick-and-place handles trays, you can use either.
