Enables RF Connectivity with the Lowest Level of Power Consumption in the Industry
DUESSELDORF (Germany), KAWASAKI (Japan), November 11, 2009 — NEC Electronics (TSE: 6723) today introduced its three new 16-bit All Flash™ microcontrollers (MCUs) with embedded IEEE802.15.4-compliant 2.4 gigahertz (GHz) radio frequency (RF) transceiver for ZigBee® RF4CE, an industry standard for remote control in consumer electronics. The new MCUs are ideal for RF remote control and provide the lowest level of power consumption in the industry. The three new MCUs come with 56 pins and 8x8mm quad flat no-leads (QFN) packages, and part numbers differ according to their flash memory capacity: the µPD78F8056 offers 64 kilobytes (KB) of flash memory, the µPD78F8057 has 96 KB, and the µPD78F8058 has 128 KB.
To support development tasks of the ZigBee RF4CE applications, NEC Electronics also provides a ZigBee RF4CE software development kit (SDK), which includes a ZigBee RF4CE stack library and a three-channel real-time sniffer, capable of simultaneously monitoring packets from the three RF4CE frequency channels, as well as an evaluation board with NEC Electronics’ µPD78F8058 MCU.
To align with advanced digital TVs, set-top boxes (STBs), Blu-ray™ disc devices and other audio-visual (AV) home entertainment devices, radio frequency remote controls alleviates several shortcomings of infra-red remote controls, such as unidirectional communication and line-of-sight limitations. The two-way communication in RF4CE remote controls enables advanced home entertainment systems to support sophisticated features. By eliminating line-of-sight problems, AV systems can form networks of their own for command-and-control purpose, thereby enhancing the user’s experience. Security features of the RF4CE standard authenticate legitimate devices and protect data exchanges within its network.
NEC Electronics began providing ZigBee-based solutions in 2004. To meet market expectations for RF remote control based on ZigBee RF4CE specifications, NEC Electronics developed these ultra-low-power MCUs integrated with a low-power IEEE802.15.4-compliant radio transceiver in one package. In addition to the RF4CE application, these MCUs also can be used for 802.14.5 wireless networking.
The primary features of the new MCUs are as follows:
(1) Lowest level of power consumption in the industry
The new MCUs combine NEC Electronics’ ultra-low-power 78K0R/Kx3-L 16-bit CPU and the ultra-low-power IEEE802.15.4 compliant 2.4 GHz RF transceiver with hardware MAC functions, realizing the lowest level of power consumption in the industry. These three offer current consumption of 18 milliamps (mA) during reception and 19 mA during transmission.
(2) Flash EEPROM programmable and erasable at 1.8V
With a built-in voltage booster, NEC Electronics’ new MCUs with radio connectivity allow applications to program and erase flash EEPROM at 1.8 V, offering longer lifetime with two dry batteries while counting frames and storing the non-volatile count values, which are key elements for security.
(3) Development support
NEC Electronics’ ZigBee RF4CE SDK includes a ZigBee RF4CE library, automatic transmission (AT) commands and its interpreter, and a three-channel real-time sniffer that can simultaneously observe packets in the three RF4CE frequency channels. An evaluation kit, which is comprised of an RF module board with an NEC Electronics µPD78F8058 MCU and a flash programming and debugging board, is also available for evaluation and prototyping.
NEC Electronics believes these new MCUs will contribute to the evolution of the next-generation remote-control functionality in consumer electronics.
Availability
Samples of the new chips are currently available. Mass production is scheduled to begin in the first half of 2010, and is expected to reach a monthly production of 1,200,000 units by 2011. A ZigBee RF4CE SDK and evaluation kit are also available now.
