NEC Electronics announced the µPD78F8056 (64 KB), µPD78F8057 (96 KB), and µPD78F8058 (128 KB) 16-bit All Flash microcontrollers (MCUs). The new microcontrollers feature embedded IEEE802.15.4-compliant 2.4 gigahertz (GHz) radio frequency (RF) transceiver for ZigBee RF4CE. The new microcontrollers come with 56 pins and 8x8mm quad flat no-leads (QFN) packages. The µPD78F8056, µPD78F8057, and µPD78F8058 MCUs are ideal for RF remote control and provide the lowest level of power consumption in the industry.
Samples of the new chips are currently available and pricing varies depending on memory capacity. For example, the unit price of the µPD78F8058 MCU with 128 KB of flash memory and 8 KB of RAM is priced at US$5 each. 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.
µPD78F8056, µPD78F8057, and µPD78F8058 Microcontrollers Features
- 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.
- 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.
- Development support
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.
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.
