Microchip Launches Platform Compliant with ZigBee RF4CE Protocol and XLP
Microchip Technology Inc. announced that its ZigBee RF4CE-compliant platform has been certified to enable a new generation of RF remote controls and consumer electronics products. The platform includes Microchip's nanoWatt XLP ultra-low-power PIC® microcontroller, MRF24J40 IEEE 802.15.4 transceiver and modules that have been certified by the US Federal Communications Commission (FCC), and the ZigBee RF4CE certification protocol stack that occupies the smallest storage space in the industry.
The consumer electronics industry is rapidly shifting from infrared remote controls that require line-of-sight operation and have limited range to more powerful and versatile radio frequency (RF) wireless technologies. The ZigBee RF4CE protocol provides an industry standard for this transition, ensuring interoperability between OEM or aftermarket remote controls and consumer electronics products, while facilitating the communication between audio / video entertainment devices and improving the user experience.
Steve Caldwell, Director of Microchip RF Product Division, said: "Microchip's RF4CE-compliant platform provides a leading ZigBee Alliance RF4CE protocol stack implementation solution for the consumer electronics industry. The RF4CE protocol running on the Microchip XLP PIC microcontroller family provides device designers with a global The lowest sleep current maximizes the battery life of its products. "
In addition to low power consumption, compatible PIC XLP microcontrollers also provide a wide range of integrated peripherals to implement capacitive touch sensing, USB, and multiple analog functions. And free software is available to support these peripherals, including Microchip's USB protocol stack and libraries, and mTouch â„¢ touch sensing software. To complement its 2.4 GHz MRF24J40 transceiver that complies with IEEE 802.15.4 and institutionally approved transceiver modules, Microchip also provides an efficient and cost-effective platform that facilitates the implementation of the new RF4CE protocol in RF remote controls and devices .
Microchip provides various development tools for PIC XLP microcontrollers, including the free MPLAB® IDE, MPLAB REAL ICE ™ emulation system, MPLAB ICD 3 in-circuit debugger, PICkit ™ 3 low-cost debugger / programmer, and Microchip's free C compiler.
Availability
Microchip's certified RF4CE protocol stack is currently available to test users and is scheduled to be fully listed in March. MRF24J40 transceivers and FCC-certified modules, as well as compatible PIC XLP microcontroller series have been available.
The short wave pass filter is a cut-off filter in the interference filter. The cut-off filter is divided into long wave pass filter and short wave pass filter, that is, the beam in a certain wavelength range is required to be transmitted, and the beam deviating from this wavelength changes to cut-off, Usually, we call the filter in the reflection (cut-off) short wave area and transmission long wave area as long wave pass filter. On the contrary, the short wave direction is transmitted, while the long wave direction is cut-off. What plays the role of isolating long waves is called short wave pass filter.
