The STM32F407ZGT6TR is a 32-bit ARM Cortex-M4 MCU from the STM32F4 series, clocked at 168 MHz. The 1 MB Flash and 192 KB RAM suit a modest embedded GUI or a CANopen stack with TCP/IP.
Peripheral set for industrial and communications gateways
This MCU carries an Ethernet MAC with dedicated DMA, two CAN 2.0B interfaces, USB OTG FS/HS, and a camera interface (DCMI). The EBI/EMI bus can glue an external SRAM or NOR Flash for a framebuffer or a large data log. 114 GPIOs in the 144-LQFP package leave plenty of headroom for a parallel LCD, a keypad matrix, and a handful of encoder inputs without needing a port expander.
Package and temperature grade — board-fit constraints
The 144-LQFP body is 20x20 mm. The -40 to 85 °C rating covers factory-floor cabinets and outdoor telecom shelters.
