HiTrendtech ATT7027 User Manual
This manual describes the ATT7027 system‑on‑chip, a low‑power, high‑performance single‑phase energy‑metering solution that integrates measurement, processor, LCD driver, and real‑time clock functions. It includes a detailed description of the chip architecture, pin layout, and functional blocks such as ADC, UART, GPIO, PWM, and power‑saving modes.
The document also covers the interrupt system, reset behavior, programming modes, on‑chip ICE support, and mechanical specifications. Appendices provide step‑by‑step instructions for using a super‑terminal to configure baud rates, load HEX files, and switch between user‑application and flash‑programming modes. This manual is written in Chinese.
