Guangzhou ZLG MCU Development Co., Ltd. is a company engaged in the sales and services of microcontroller products. The company is based in Guangzhou and has a sales and service network throughout the country.
The AMIS-49587 is a power‑line carrier modem designed for 50 Hz and 60 Hz electric grids. It uses spread‑frequency shift keying (S‑FSK) modulation and integrates an ARM7TDMI core with a MAC layer, providing robust low‑speed communication over power lines.
Key features include programmable carrier frequency, selectable data rates, RoHS‑compliant lead‑free packaging, and a serial SCI interface for microcontroller integration. Typical applications cover automatic remote meter reading, street‑lighting control, and alarm transmission. This manual is written in Chinese.
