ATT7027 user manual is a user manual of ATT7027 released by HiTrendtech Co., Ltd. It mainly introduces the features, structure, electrical characteristics, instruction system, interrupt system, clock and other contents of ATT7027.
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.
| Operating voltage range | 2.7 V‑3.6 V |
|---|---|
| Operating temperature range | -40 °C to 85 °C |
| Package | Lead‑free LQFP64 |
| Typical active current | < 6 mA |
| Low‑speed current consumption | < 80 µA |
The baud rate can be set to other values such as 4800 or 19200 in the super‑terminal configuration.
Enter “M0000”, then “M8000”, then “E”, and finally “L” to send the HEX file; all commands must be uppercase.
After resetting, change the mode to normal (UAM) and the program will start running from address 0x0000.
