Gleichmann Electronics presents 22 new low power 16-bit MCUs from NEC Electronics
78K0R/Kx3-L MCUs with very low power consumption guarantee long battery life
Many features have been optimized. For example, power consumption at 20 MHz operation has been reduced by 20% to 6.5 milliamperes (mA) and at 10 MHz operation by 10 percent to 3.5 mA. Even more significant is the optimization of the power management circuitry, which is reflected in the standby power consumption. When only the real-time clock is active the power consumption of the 78K0R/Kx3-L family reduces to 1.0 microampere (µA). This was previously, an average of 2.4 µA. By reducing the internal supply voltage from 2.4 V to 1.8 V in "low consumption current mode", the overall power consumption can be further reduced.
On-chip oscillator circuits allow the MCUs to be operated at a different clock speeds of 20 MHz, 8 MHz or in a special power-saving mode 1 MHz. Thanks to a guaranteed error rate of less than 1 percent at operating frequencies of 8 and 20 MHz , the need to add an external quartz/resonator, even for asynchronous data transfers, is eliminated.
Especially interesting for sensor applications; an optimized 12-channel, 10-bit A/D converter circuit, which is also integrated on the 78K0R/Kx3-L family, reduces the conversion time of an analog input into a digital output from 6 to 3 microseconds (µs). In addition, one internal operational amplifier and two internal comparators allow a wide range of analog data to be measured.
Because of the low power consumption and the extensive peripheral functions, the 22 new MCUs of the 78K0R/Kx3-L family are ideally suited for use in portable equipment or with sensor-equipped systems such as fire alarms, security devices, meters, industrial sensors, hand-held medical diagnostics devices as well as data acquisition and point-of-sale (POS) terminals.
Samples will be available from the third quarter of 2008. Start of volume production is planned for the end of 2008.
NEC Electronics (Europe) GmbH
NEC Electronics (Europe) GmbH, headquartered in Duesseldorf, Germany, is a leading developer and supplier of semiconductor products in Europe. Committed to meeting customers' cost, performance and time-to-market requirements, the company offers solutions ranging from standard products to system-on-a-chip (SoC) solutions, as well as customized products for next-generation designs. Our customers also benefit from state-of-the-art manufacturing from the global production network of our parent company, NEC Electronics Corporation.

MSC Technologies GmbH
Founded in 1979, Gleichmann & Co. Electronics GmbH, in the same company group with MSC Vertriebs GmbH, has established itself as one of the leading pan-European distributors of electronic assemblies and components. One of the reasons for the high acceptance by customers and suppliers is the company's early focus on comparatively few, highly sophisticated products such as microcontrollers, programmable logic devices, displays and customer specific power supplies. From this, the resulting in-depth technical know-how of our sales engineers and field application engineers today enables us, if required by the customer, even implementation of complete new designs right up to the finished product. With two of its own ASIC design centers, the Gleichmann research laboratory in Austria and one of the largest and most modern programming centers in Europe, Gleichmann Electronics takes a leading role in terms of service and customer support.
