Details Information


Introduction


3121N-ISF is a fully integrated power carrier (PLC) communication module with ultra-miniature size, compact structure and simple wiring. It can be widely used in various PLC instant communication application scenarios such as intelligent street lamp, intelligent home, intelligent parking, central air conditioning and ubiquitous power IoT terminal equipment.

3121N-ISF is based on HiSilicon Hi3921SV100 chipset, which integrates high-speed/low-speed multi-mode power line carrier communication modem and ARM Cortex-M3 processor. The Hi3921SV100 chipset supports P1901.1 and supports OFDM/FSK modulation.

3121N-ISF provides rich peripheral interfaces such as UART, PWM, GPIO, I2C, SPI, ADC, etc., and integrates a built-in Line-Driver. Equipped with Huawei IoT open source operating system LiteOS, it provides a more open development environment and a faster and safer operating system.


 Features 

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.

Peripheral interfaces

I2C interface, UART interface, GPIO interface, PWM output, SPI,ADC input.

Communication indicators

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

The receiving sensitivity is better than 0.2mVpp.

Power consumption and others

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

Dynamic operating power ≤0.7W.

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

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

Package size: LxWxH:22.3*13.0*2.40mm.
