The 22 new 16-bit All FlashTM microcontrollers of the 78K0R/Kx3-L series from NEC Electronics (Distribution: Gleichmann Electronics) feature ultra-low power and high performance. First samples will be available at the end of September 2008.
Recent measurements resulted in a current consumption of just 0.52 mA/MIPS at 20 MHz clock frequency. The dedicated real-time clock function requires only 1.0 µA in standby operation. At the same time, a performance of 0.65 DMIPS/MHz (Dhrystone 1.1) was determined. According to NEC Electronics, with a power consumption of 1.5 mW/MIPS the 78K0R/Kx3-L series thereby offers the industry's leading power / performance ratio.
Regarding peripherals, the 16-bit microcontrollers of the 78K0R/Kx3-L series with - depending on the version - 16 to 60 Kbytes of Flash memory feature: high-speed A/D converters that work across the entire supply voltage range of 1.8V to 5.5V, programmable operational amplifiers, two comparator channels, flexible 16-bit timer serial interface arrays, standard units such as real-time clock, DMA controller, window watchdog timer and other safety functions. Furthermore, three integrated oscillator circuits generating 1MHz, 8MHz or 20MHz clock at +/-1% accuracy are available to the user.
In common with all NEC Electronics' microcontrollers, the 78K0R/Kx3-L series is specified across the whole temperature and supply voltage ranges.
