[原创] ST STM32F334C8 500W全数字电源解决方案

ST公司的STM32F334x4/6/8系列产品是高性能32位ARM Cortex-M4 MCU,工作频率高达72MHz,并嵌入了浮点单元(FPU),集成了高速嵌入存储器(多达64KB闪存和多达12KB SRAM)以及连接于两条APB总线的各种增强I/O和外设.本文介绍了STM32F334x4/6/8系列产品,框图,以及采用STM32F334C8 MCU的500W 全数字AC/DC电源STEVAL-ISA147V2主要指标,框图,电路图,材料清单和PCB元件布局和走线图.

The STM32F334x4/6/8 family is based on the high-performance ARMR32-bit CortexR-M4 RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU). The STM32F334x4/6/8 family incorporates high-speed embedded memories (up to 64 Kbytes of Flash memory, up to 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32F334x4/6/8 devices offer a High resolution timer, two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a lowpower RTC, one high-resolution timer, one general-purpose 32-bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers. They also feature standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.
