【选型】可替换NXP LPC4074的32位国产MCU AT32F403A,片上资源更丰富
当今,随着科技的飞速发展,MCU产业较40年前也发生了深刻的变化。不同领域的产品功能越来越全面,相应地,对MCU的要求也越来越高。传统的8位MCU处理能力已经不太能满足要求,32位MCU已经成为未来市场主流。在过去的十多年里,移动市场的快速兴起、Arm Cortex-M系列的横空出世,加上ST、NXP、TI和瑞萨等厂商的助力,MCU从早期的百家争鸣,转向了以Arm Cortex-M为主导的市场。在Arm内核和生态的助推下,国内的MCU厂商也如雨后春笋般冒起,以更低的价格和良好的兼容性迅速在市场占据了一席之地。雅特力就是其中一位。
众所周知NXP的LPC4000系列是其为LPC177x/8x系列设计的内核升级版芯片(Cortex-M4内核),那么它的性能和雅特力的产品比较如何呢?我们以LPC4074和雅特力国产MCU AT32F403A为例来看一下参数对比。
如上表所示,LPC4074与AT32F403A算是同级别的产品,不存在降维打击。二者虽然都是Cortex-M4的内核,但是AT32F403A主频高达240MHz,性能更好,处理速度更快。在存储容量上,AT32F403A比LPC4074更大。在接口上,AT32F403A相较于LPC4074拥有更多的UART、SPI和I2S。并且,AT32F403A拥有更多的定时器,更高精度的DAC以及更多通道的ADC。另外,AT32F403A的工作温度高达105℃,相较于LPC4074的85℃,可以更好的应用于工业领域。额外地,AT32F403A还拥有sLib安全库,可以用来做核心算法加密保护。
根据以上分析可知,在功能上AT32F403A可以完全替代LPC4074,在封装上,虽然AT32F403A没有LPC4074类似的封装,但是AT32F403A拥有QFN48的小封装,具有更小的体积和占用面积。另外,雅特力作为国产芯片公司,在价格上也具有不可磨灭的优势。
综上所述,AT32F403A凭借其丰富的片上资源分配、高集成及高性价比的一流市场竞争力,适用于工业自动化、电机控制、IoT以及消费电子等各种成本敏感及高运算需求的设计。
