STM32F103VET7

The STM32F103xC, STM32F103xD, and STM32F103xE MCUs support various types of memories, including Flash memory ranging from 256 to 512 Kbytes, SRAM up to 64 Kbytes, and a Flexible Static Memory Controller (FSMC) with four Chip Select outputs that support Compact Flash, SRAM, PSRAM, NOR, and NAND memories. Additionally, they also have an LCD parallel interface in 8080/6800 modes.

The STM32F103xC, STM32F103xD, and STM32F103xE MCUs have a total of five communication interfaces available. These include three universal synchronous/asynchronous receiver transmitters (USART1, USART2, and USART3) and two universal asynchronous receiver transmitters (UART4 and UART5) .

The maximum frequency of the ARM 32-bit Cortex-M3 CPU in the STM32F103xC, STM32F103xD, and STM32F103xE MCUs is 72 MHz.
