 Merkmale 

CPU and Storage Performance

High-performance Cortex-M3 processor, working frequency 200MHz.

Embedded SRAM 256KB.

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.

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.

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, and support unicast, multicast and broadcast command propagation methods.

Peripheral interfaces

I2C interface, UART interface, GPIO interface, PWM output.

Communication indicators

The peak rate of the physical layer is 0.507Mbit/s, and the rate of the application layer is 80Kbps.

Built-in Line Driver, transmitting power -51dBm/Hz (software supports configuring the transmitting power to -45dBm/Hz).

The receiving sensitivity is better than 0.2mVpp, and the receiving sensitivity can reach -98dbm (transmitting power -51dBm/Hz, under laboratory conditions, the 30% packet receiving success rate is the benchmark).

Software

The open operating system LiteOS provides an open, efficient and safe system development and operating environment. Flexible protocol support and expansion capabilities.

The software supports whitelist recognition, the hardware implements AES128/256 encryption and decryption algorithms, RSA signature verification algorithms, and HASH anti-tampering algorithms. EFUSE is integrated internally, which supports key storage, secure boot, and meets Huawei's security requirements.

Power consumption and others

Static power consumption ≤0.15W (networking does not send packets).

Dynamic operating power ≤0.5W.

Operating temperature range: -40°C to +85°C.

Storage temperature range: -40°C to 125°C.

Package size: 28.12*18.00*5.80mm (the height does not include the height of the 2.54mm pitch pin header).
