STM32 F3 series mixed signal MCU with DSP and FPU instructions

STM32 F3 series single-chip microcomputer has run on 72 MHz 32-bit ARM ® architecture ® - M4 kernel (with FPU and DSP instructions) and integration of a variety of analog peripherals, thereby reducing costs and simplify application design, it includes:

• super fast comparator (25 ns)

• operational amplifier with programmable gain

• 12 DAC

• super fast 12-bit ADC, single channel 5 M samples per second (5 million samples per second), 18 M samples per second in alternating mode

• exact 16-bit sigma-delta ADC (21 channels)

• kernel-coupled memory SRAM (program accelerator) is a dedicated memory architecture for improving time-critical program performance by 43%

• 144mhz advanced 16-bit pulse width modulation timer (resolution < 7ns) for control applications

• high resolution timer (217 ps), self-compensation for power supply and temperature drift

Flexible interconnection matrix can communicate autonomously between peripherals, saving CPU resources and power consumption.

It is highly compatible with STM32 F0 series MCU and ensures excellent efficiency in the design of subsequent applications with different performance levels.
