The new members XC82x and XC83x of the XC800 microcontroller (MCU) portfolio are expected to contribute significantly to cost saving potentials; especially on the Asian market. There the market for inductive cooking and air conditioning seems to be very attractive. Hoika’s view is: “Asian people have quite different cooking behaviors compared with Europeans and a less-than-perfect infrastructure (gas!), so inductive cooking is very common”, he explains and adds: “Here we see a cost saving potential of about 25% and even higher are the savings in the air conditioner business when using intelligent compressor controls, they could be about 30 to 40%.” Looking to Europe, lighting and motor controls are also very interesting areas for the company, he affirms. Using electronic ballast with lighting users can amount to cost savings of up to 25% and with inverters the saving potentials climbs to at least 40%.

An example: There are about 100 Mio. heat circulation pumps at private homes in the European Union (EU), with an annual energy consumption of 50TWh. “This equates to about 2% of total annual energy consumption in the EU and more than 30 Mio. t/a. of CO2”, he continues explaining. These figures contribute 5 to 10% to private energy bills. “With the introduction of electronically controlled motors the cut of consumption could be 60% minimum”, he says referring to a 2009 study of Energy+Pumps ”Low cost and easy-to-use microcontrollers like our XC82x and XC83x series will help system designers introduce high efficiency designs with no compromise in the use of sophisticated control methods.”
Better energy efficiency and reduced system costs are key goals in the design of modern motor controllers used in fans, pumps and compressors, in new types of lighting solutions, and in any kind of power converters. That’s the reason why Infineon continues to focus on its 8-bit MCUs to be able to address the growing demands of the implementation of intelligent control concepts and connectivity with various communication interfaces: The XC82x and XC83x series combines a standard 8051 CPU and peripherals optimized to enable high energy savings at very low implementation costs. In addition, these MCU’s feature sets allow for the integration of real time embedded control (for drives, light or power management) with HMI functions like touch-sense or displays and thus minimize the bill of material.

With prices starting below 0.40 Euro (in 100k unit quantities), the two MCUs may enable a cost-effective implementation of energy saving control concepts. The features comprise capacitive touch sense and LED matrix controller, EEPROM emulation, 10-Bit A/D Converter (ADC, 16 MHz, sample time: 125 ns, conversion time: 820 ns), Capture Compare Unit (CCU6, 48 MHz) with hardware link to ADC, window watchdog timer, power down modes, and various communication interfaces such as UART, high speed SPI and I2C. The XC82x series integrates a Multiply-Division-Unit (MDU). The XC83x provides a 16-Bit vector computer and a ROM library for field oriented control functions, and high current pads (30mA to 50mA).
To implement efficient system designs using 8-bit MCUs, both of the new series provide generation of high resolution PWM signals, fast ADC measurements, autonomous peripherals, and comparators for control loop and for protection In addition, the integrated ADC limit checker realizes a digital comparator with 8-bit resolution.
Infineon offers a variety of application kits and tools: With “inDrive800” there is a complete 8-bit solution for drives and automation applications available. “Engineers do not need to start from scratch but can base their design on Infineon’s application kits available in various power classes and functionality schemes”, Hoika clarifies. A free IDE and tool chain supports easy selection and configuration of the right MCU and reuse of application specific source code. The application kit with “inTouch800” provides support for highly integrated human machine interfaces. Capacitive touch control and operation of LED-displays or stepper gauges without further driver-devices is managed with a 24-pin MCU.
Furthermore Infineon’s tool partner Keil is offering a new version of its C51 Compiler. ”The Infineon XC800 series provides efficient capabilities for industrial, automotive and other embedded applications,” said Reinhard Keil, Director of MCU Tools, ARM Germany. ”The Infineon XC82x and XC83x series extend the device range for cost-sensitive embedded applications, we are enhancing the features of the Keil C51 Compiler in order to increase performance and code density.”
The portfolio of the XC82x and XC83x series ranges from 2 KByte to 8 KByte of programmable flash and from 16-pin to 28-pin package variants, with temperature robustness up to +125 °C. Dedicated variants to meet ACQ100 requirements for automotive applications are also part of the portfolio. Single unit prices range from 0.39 Euro (US $0.55) to 0.72 Euro (US $1.01) in 100k quantities. Engineering samples of the XC82x series are already available, samples of the XC83X series come to market in April 2010.

Our team had very unique time at Blog World Los Angeles, there was so much infiamrtoon (all most too much lol) also ePN booth were awesome. we learned so much about ePN in general and they were very helpful (especially Mr Bexelius). Thank you again!!
