M0 Kernel/512K Flash MCU

Product overview
      HT603X series MCU is designed for the new generation of smart meter applications in the country. The kernel uses a ARM Cortex-M0 processor which was highly optimized in size, power consumption, and energy efficiency. The chip is also equipped with 512K Flash, 64K SRAM, power and reset management, clock management, temperature sensor, automatic temperature compensation RTC, LCD driver, AES/GHASH/ECC hardware encryption and decryption and other rich IP. Products meet the requirements of the high requirement of State Grid for the MCU device in the function, performance and reliability of the meter. 
      The MCU series is particularly suitable for the national grid meter system, is also suitable for other types of integration, reliability, and accuracy of RTC standby power consumption of high requirements of the industrial control, consumer electronics and other terminal applications. Compared with the traditional 8bit/16bit industrial control MCU, this series has more prominent comprehensive cost performance and platform advantages.
