Fujitsu has introduced two new System-on-Chip solutions for FSK-based Powerline Communication. The MB87S2090 and MB87S2090-F have been developed in association with ADD Semiconductor. Both devices are pin-to-pin compatible with ADD Semiconductor’s designs.
The MB87S2090 is a Powerline Communication SoC, which implements a full Powerline Communication node using A, B and C band FSK modulations and is IEC61334-5-2 compatible. It includes an enhanced 8051 microcontroller, a MAC and a modem circuit. A complete set of peripherals has been developed achieving a high level of versatility and providing a compact, low-cost solution for automated meter reading / automated meter management applications using narrowband Powerline Communications. Based on the MB87S2090 a single-phase smart meter can be realised without the need for additional microcontrollers.
The MB87S2090-F is a full Powerline Communication SoC, which implements a full Powerline Communication node using FSK C-band modulation and is compliant to EHS and Konnex standards for building automation as well as IEC61334-4-32. The device has been designed to target and simplify Powerline-based building automation, safety, security and control applications as well as energy-saving applications such as intelligent street lighting or solar panel management.
Like the MB87S2090, the MB87S2090-F integrates an enhanced 8051 microcontroller, a hardwired MAC and a CENELEC FSK modem on one chip. As the MAC is hardwired, the integrated CPU can be used to perform application tasks. Five serial communication interfaces (3 UARTS, 2 SPI) secure communication to the outside, while integrated PWM timers can be used to switch or dim lights or manage other loads. The device only needs a simple coupling circuit and significantly reduces the number of components required for a Powerline Communication application.
