ht5027's Introduction

sites

HT5027是一颗低功耗、高性能的单相电能计量 SoC 芯片,片内集成 32-bit ARM 内核、256K flash、32K SRAM,支持断相防窃电功能的硬件 EMU 模块,带有温度自补偿功能的高精度 RTC 模块,以及 LCD驱动等功能,为单相多功能、防窃电电能表提供高集成的单芯片解决方案。

相对于传统51核的计量SoC,该系列则具备更为突出的综合性价比及平台化优势,特别是对应到海外的防窃电应用场合,其在低功耗方面的性能表现则更为突出。

HT5023配有79个GPIO、6路UART、7个外部中断,LCD支持4x43/6x41/8x39段,采用LQFP100封装,且向下兼容HT5013。

HT5025配有59个GPIO、5路UART、5个外部中断,LCD支持4x34/6x32/8x30段,采用LQFP80封装,不支持SPI、I2C通讯,且向下兼容HT5015。

HT5027配有43个GPIO、3路UART、4个外部中断,LCD支持4x24/6x22/8x20段,采用LQFP64封装,不支持SPI、I2C通讯,且向下兼容HT5017。
