Details information

 Features 

CPU and Storage Performance

Hisilicon Hi3921E high-performance Cortex-M3 processor, working frequency 200MHz.

Embedded SRAM 256KB.

Plug-in 2MB Flash.

PLC Physical Layer Features

Realize a subset of the IEEE 1901.1 standard. For chips that also use this subset, they can achieve interconnection and interoperability.

Supports two frequency bands of 0.5-3.7MHZ and 2.5-5.7MHZ. The frequency bands can be configured by software.

Adopt OFDM technology; support BPSK, QPSK modulation mode.

Support FEC and CRC functions, powerful denoising and error correction capabilities.

PLC MAC Features

Support TDMA and CSMA/CA, and provide conflict avoidance mechanism.

Support data segmentation and reorganization to improve transmission efficiency.

Support data retransmission mechanism.

Support 4-level QoS to meet different business service quality requirements.

PLC Networking Features

Supports automatic and fast networking, typical 200-scale, 2-level network scenarios, complete fast networking in 10s, and support fast communication.

Support dynamic routing, multi-path addressing.

Other interfaces

UART

Communication indicators
