The STM32F437VGT7 ARM Cortex-M4 single-core runs at 180 MHz with 1 MB Flash and 256 KB RAM in a 100-LQFP tray package.
On-chip peripherals include Ethernet MAC, CAN 2.0B, USB OTG (host/device), multiple SPI, I²C, and UART/USART interfaces, plus an EBI/EMI bus for external SRAM or NOR Flash.
The core runs at 180 MHz, which is the maximum clock speed for this part. At that frequency the Flash requires one wait state for zero-wait access; the reference manual details the clock-configuration sequence.
Within the STM32F4 family, pin-compatible alternatives exist with different Flash/RAM densities (e.g., STM32F427VGT6 with 1 MB Flash / 256 KB RAM at 180 MHz, or STM32F407VGT6 with 1 MB Flash / 192 KB RAM at 168 MHz). These share the same 100-LQFP footprint but differ in peripheral set and memory size — verify the specific feature differences against your firmware requirements before substituting.
