STM32 F3 series of mixed-signal MCUs with DSP and FPU instructions

The STM32 F3 series of microcontrollers combines a 32-bit ARM Cortex-M4 core with a DSP and FPU instructions running at 72 MHz with advanced analog peripherals for more flexibility. This series innovates in embedded DSC design by combining a Cortex-M4 core with fast 12-bit 5 MSPS and precise 16-bit sigma-delta ADCs, programmable gain amplifiers (4 gains, 1% accuracy), fast 50 ns comparators and versatile time control units running at 144 MHz, giving optimum integration.

The STM32 F3 series allows designers to tackle mixed-signal control applications. The devices are optimized for efficient handling and processing of mixed signals in circuits such as 3-phase motor controllers, biometrics and industrial sensor outputs or audio filters. They help simplify design, cut power consumption and reduce PCB size in consumer, medical, portable fitness, system monitoring and metering applications. 

Pin compatible with the STM32 F1 series, the new STM32 F3 series enlarges the STM32’s Cortex-M4 portfolio which now offers both entry-level cost with the F3 series and highest performance with the F4 series.
The STM32 F3 series includes devices with 64 to 256 Kbytes of on-chip Flash memory, up to 48 Kbytes of SRAM and is available in WLCSP66 (less than 4.3 x 4.3 mm), LQPF48, LQFP64, LQFP100 and UFBGA100 packages.

从官网考过来的,新的芯片,中文要自己翻译,,并且词汇语法都不复杂,就偷个懒了

是的,新出的stm32的一个系列,偏重模拟并具有相对较好的处理功能,如果价格还那么给力,应该会火

其实这种文章语法和词汇都比较简单,还是直接读好

应该说各有特点
另外TI和ST的销售策略不一样,
如果你的量非常大,据说价格会比较惊人

两个系列的定位不太一样,F3的外设强调模拟功能,而DSP单元应该是与之相配合的

哈哈,高端的DSP用的太多了吧

所谓集成DSP,在这种级别的微控制器中,一般是硬件集成一个乘-累加单元,较少的周期甚至一个周期里面完成进行FFT最核心的乘-累加过程,可能还有一些其他的辅助的硬件优化措施,TI的C2000,MICROCHIP的DSPIC,INFINEON的XE16x,XC16x都是这样的……

现在各家比较默契,不管原来叫DSP,还是单片机,现在都叫DSC
