STM32F103x4和STM32F103x6: Low-density performance line, ARM-based 32-bit MCU with 16 or 32 KB Flash, USB, CAN, 6 timers, 2 ADCs, 6 communication interfaces The STM32F103x4 and STM32F103x6 performance line family incorporates the highperformance ARM Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed embedded memories (Flash memory up to 32 Kbytes and SRAM up to 6 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN. The STM32F103xx low-density performance line family operates from a 2.0 to 3.6 V power supply. It is available in both the –40 to +85 ℃temperature range and the –40 to +105 ℃ extended temperature range. A comprehensive set of power-saving mode allows the design of low-power applications. The STM32F103xx low-density performance line family includes devices in four different package types: from 36 pins to 64 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family.

圖1.STM32F103xx方框圖 STM3210E-EVAL評估板 The STM3210E-EVAL evaluation board is designed as a complete development platform for STMicroelectronic’s ARM Cortex-M3 core-based STM32F103ZGT6 microcontroller with full speed USB2.0, CAN2.0A/B compliant interface, two I2S channels, two I2C channels, five USART channels with smartcard support, three SPI channels, two DAC channels, FSMC interface, SDIO, internal 96 KB SRAM and 1 MB Flash, JTAG and SWD debug support. The STM3210E-EVAL products delivered with the MB672 board versions D-03 or older are based on the STM32F103ZET6 instead of the STM32F103ZGT6 and include 64 KB internal SRAM and 512 KB Flash. The board number and version are on a label on the bottom side of the board. The full range of hardware features on the board helps you to evaluate all peripherals (USB, motor control, CAN, MicroSD Card, smartcard, USART, NOR Flash, NAND Flash, SRAM) and develop your own applications. Extension headers make it easy to connect a daughterboard or wrapping board for your specific application.
