STM32G4 Series of mixed-signal MCUs with DSP and FPU instructions
The STM32G4 Series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz combined with 3 different hardware accelerators: ART Accelerator™, CCM-SRAM routine booster and mathematical accelerators. The STM32G4 Series also offers:
Rich advanced analog peripherals (comparator, op-amps, DAC)
ADC with hardware oversampling (16-bit resolution)
Dual-bank Flash memory with error-correcting code (ECC) (supports in-field firmware upgrades)
Securable memory area
High-resolution timer version 2
USB Type-C interface with Power Delivery including physical layer (PHY)
AES hardware encryption
Cortex-M4F内核,170M主频,Flash ART加速器,CCM 内核耦合存储器,数学加速器
数学加速器包括一个CORDIC协处理器,可以进行三角函数、开方、对数等运算;并且还有一个硬件的滤波器单元,可以运行FIR和IIR滤波器;
非常丰富的模拟外设,5个12位ADC,7个DAC,6个运放,7个比较器
ADC具有硬件过采样功能
定时器功能得到很大加强,不对称PWM模式,复合PWM模式,新的单脉冲模式,新的Pulse on compare mode,新的编码器输入模式
3个FDCAN
......
值得一提的是,G4系列的Nucleo 评估板采用了新设计的硬件,板载的是STLINK-V3
