ST STM32F20x系列家庭能量管理网关解决方案

ST公司的STM32F20x系列是基于高性能ARM®Cortex™-M3 32位RISC内核的微控制器,工作频率高达120MHz,具有高速嵌入存储器(闪存高达1MB,128KB系统SRAM), 4KB备份SRAM以及各种增强I/O和外设,主要用在马达驱动和应用控制,医疗设备,家用音频设备,PLC,逆变器和电路中断器,打印机和扫描仪,告警系统,视频互连和HVAC等.本文介绍了STM32F20x系列主要特性,框图,以及评估板STM3220G-EV主要特性,框图,电路图和家庭能量管理网关框图.

The STM32F20x family is based on the high-performance ARM®Cortex™-M3 32-bit RISC core operating at a frequency of up to 120 MHz. The family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

The devices also feature an adaptive real-time memory accelerator (ART Accelerator™) which allows to achieve a performance equivalent to 0 wait state program execution from Flash memory at a CPU frequency up to 120 MHz. This performance has been validated using the CoreMark benchmark.
