Carry out Hybrid Powerline And Wi-fi Communication With This Chipset

Flip-key resolution based mostly on programmable multi-protocol SoC and ultra-low-power sub-GHz S2-LP RF transceiver

STMicroelectronics has introduced that the ST8500 and S2-LP chipset has been licensed in keeping with the G3-PLC Hybrid communication customary that defines seamless connectivity over powerline and wi-fi media. The G3-PLC Hybrid specification permits smart-grid, smart-city, industrial and IoT tools to pick out one of the best out there wi-fi or powerline channel at any time, robotically and dynamically, in keeping with community circumstances. This permits superior protection, reliability and scalability, whereas additionally permitting cost-efficient system operation that permits new use instances.

Broadly utilized in smart-metering, good industrial and infrastructure purposes, the ST8500 powerline communication SoC platform is most popular by key stakeholders within the smart-grid market. On the identical time, the {hardware} and firmware resolution has been chosen to energy the official G3-PLC Alliance RF certification-testing tools.

Primarily based on 6LowPAN and IPv6 and mixing RF connectivity with the native G3-PLC protocol stack, lower than 100mW is consumed by ST8500 SoC in obtain mode, making certain ultra-low-power efficiency for minimising the grid load imposed by new good meters. It incorporates a high-performance DSP for real-time protocol processing and an ARM Cortex-M4F core for upper-layer processing and system administration. Each the DSP and ARM core have their code and knowledge SRAM on-chip, whereas peripherals together with a 128/256-bit AES cryptographic engine are built-in to fulfill the wants of smart-energy purposes. The Analogue Entrance Finish (AFE) for connecting to the STLD1 line driver can be built-in. The STLD1 communicates reliably, even throughout noisy energy cables and with low impedance, with excessive drive functionality and excessive linearity.

The S2-LP is a high-performance ultra-low-power RF transceiver, supposed for RF wi-fi purposes within the sub-1GHz band. It operates in each the license-free ISM and SRD frequency bands at 433, 512, 868, and 920 MHz, and could be programmed to function at further frequencies within the 413-479 MHz, 452-527 MHz, 826-958 MHz, and 904-1055 MHz bands. The transceiver permits an RF-link finances better than 140dB for lengthy communication ranges and meets radio-equipment laws in territories worldwide together with Europe, North America, China and Japan. ST gives companion built-in balun/filter chips for the S2-LP that simplify antenna-connection circuitry and save PCB space in space-constrained purposes.

The licensed chipset combines the ST8500 programmable multi-protocol powerline communication system-on-chip (SoC) and STLD1 line driver with ST’s S2-LP ultra-low-power sub-GHz radio transceiver. The SoC’s programmability permits a software-defined implementation able to supporting a broad portfolio of powerline protocol stacks in worldwide frequency bands comparable to CENELEC and FCC.

The ST8500 SoC is packaged as a 7mm x 7mm x 1mm QFN56. The STLD1 and S2-LP are every packaged as 4mm x 4mm x 1mm QFN24. All gadgets are in full manufacturing and out there from STMicroelectronics.
