STMicroelectronics STM32F302x6/x8 ARM-Cortex-M4 32 位 MCU

STMicroelectronics STM32F302x6/x8 ARM®-Cortex®-M4 32 位 MCU 基于高性能 ARM Cortex-M4 32-bit RISC 核心，在高达 72MHz 的频率下工作并嵌入一个浮点运算单元（FPU）。该系列内含高速嵌入式存储器（高达 64 千字节闪存、16 千字节 SRAM），广泛的增强型 I/O，和连接两个 APB 总线的外设。这些器件具有一个快速的 12 位模数转换器（5Msps）、三个比较器、一个运算放大器、多达 18 个电容传感通道、一个数模转换器通道、一个低功耗 RTC、一个通用 32 位定时器、一个电机控制专用定时器、三个通用 16 位定时器以及一个用于驱动数模转换器的定时器。它们还具有标准化的和高级的通信接口：三个 I2C、多达三个 USART、多达两个带多路复用全双工 I2S 的 SPI、一个 USB FS 设备、一个 CAN和有一个红外发射机。

The STMicroelectronics STM32F302x6 and STM32F302x8 MCUs operate in the –40°C to +85°C and –40°C to +105°C temperature ranges from at a 2.0V to 3.6V power supply. A comprehensive set of power-saving mode allows the design of low-power applications. These devices are offeredin 32-pin, 48-pin, 49-pin, and 64-pin packages.
