ELECTRONICS DESIGN FLExIbILITy Cost-effective and highly configurable modules are crtical to widescale adoption of PLC-based command and control systems. To achieve that goal, designers need highly reliable and affordable components. One of the first modem ICs for these applications is the PLM-1, designed by Ariane Controls and available in volume from NEC Electronics America. Utilizing licensed intellectual property from Ariane’s PLC technology. The PLM1 integrated circuit was designed on NEC Electronics’ CMOS-9HD quick-turn, gate-array platform and fabricated on a small, 44-pin, low-profile, quad-flatpack package, allowing for easy integration into the powerline transceivers applications. The PLC modem IP is easily migratable throughout NEC Electronics’ process technologies to provide ASIC customers with a critical PLC building block, as well as added functionality to NEC Electronics’ standard solutions lineup for emerging applications in the smart grid, intelligent lighting control and HAN markets The PLM-1 modem implements a half-duplex transmitter/receiver for PLCs using a frequency shift-key modulation technique. The modem also supports programmable transmission rates ranging from 100 baud to 20,000 baud and communication frequencies ranging from 50 kHz to 500 kHz. The protocolneutral device also features a set of high-level functions designed to simplify the implementation of high-performance PLC networks. To ensure reliable communication, the chip also provides on-chip cyclical redundancy check (CRC), error detection and forward-error detection functions. Operating at 3.3 V, the chip minimizes power consumption by dissipating as little as 24 mW of power. Fig. 2. PLM-1 block diagram. Designers developing complete PLC solutions can complement the PLM-1 with different devices in NEC Electronics’ line of microcontrollers (MCUs) for different applications. For example, a designer could combine the PLM-1 with a lowcost 8-bit 78K0 MCU for simple appliance control functions. For more sophisticated applications, such as network bridging or combination PLC + Zigbee communica- tions, an efficient solution offering more integrated memory support for NEC Electronics’ Zigbee software protocol stack would fall under the 16-bit 78K0R MCU family. Finally, in complex applications, such as a smart meter to manage signals between multiple appliances and the utility, the designer could select one of NEC Electronics’ higher-performance 32-bit V850 MCUs. < LOW COST Variable Speed Controls For Fans, Blowers, Humidiers, Stoves, Heaters, Whole House Ventilators, Range Hoods, Lamps. . .
