Fudan Microelectronics EC301v02 Chip Data Sheet
The EC301v02 chip provides DCP signaling functions and fault detection for field telephone applications. It supports DCP, magnetic‑loop (LB), common‑bus (CB) modes and an automatic sleep mode to reduce power consumption. Fault detection can locate line faults up to 10 km away with about 500 m accuracy.
The device communicates with a host MCU via a synchronous serial interface (STE, SCLK, SD, IRQ). It is implemented in a 20‑pin plastic dual‑in‑line package, with detailed electrical characteristics such as 4 mA static current, 1 µA sleep current, and a supply range of 2.8‑5.5 V. This manual is written in Chinese.
