Infineon Technologies AG has launched a low-cost evaluation kit for the company's XC800 8bit embedded flash MCU family. The new XC800 USCALE kit is contained in a USB stick that provides full evaluation capabilities for the XC866, XC886 and XC888 MCUs on a single platform.

The USCALE kit offers access to the key featuressuch as CAN, ADC, capture compare unit, timers and vector computer for field oriented controland to the hardware signals of each of the three MCUs for extensive benchmarking and evaluation. It ensures quick installation and ease-of-use due to its development tool chains, demos and tutorials, said Infineon.

The high-performance XC800 series of MCUs combine an enhanced 8051 core with embedded flash memory and powerful on-chip peripherals. The three MCUs supported in the USCALE kit are well-suited for different applications including motor control, automotive body and white goods. They are also claimed to add networking functionality to industrial and building automation systems.

Technical specifications
Performance and cost-saving features of the XC866 MCU series include a 26.67MHz system frequency, 4Kbytes up to 16Kbytes of flash memory, an on-chip oscillator and PLL for clock generation, an embedded voltage regulator supporting single voltage supply of 3.3V or 5V and EEPROM support. The enhanced PWM unit offers advanced features including integrated dead-time control, emergency-OFF control, direct Hall-sensor inputs and a tight coupling with ADC for automatic triggering. The 10bit ADC with a conversion time of only 1.5?s offers advanced features like auto-scan and comparator modes. The Infineon XC866 also offers a set of communication interfaces including LIN, SSC and UART. The XC866 is available in an RoHS compatible TSSOP-38 package with a temperature range of up to 140C to offer 27 GPIOs with an extremely small footprint of 9.7mm x 4.4mm.

The XC886 and XC888 MCUs, both with up to 32Kbytes flash memory, provide advanced networking capabilities, based on integration of both a full CAN controller and LIN support on a single chip. The on-chip CAN module offloads the CPU handling most of the networking functions. Advanced features of the XC886 and XC888 MCUs include high compute power supported by a 16bit multiply and divide unit (MDU) for fast mathematical computation and a CORDIC or COrdinate Rotation Digital Computer unit at a 16bit coprocessor dedicated for vector rotation angular calculations (for field oriented motor control). Additional key features are an intelligent PWM unit, a highly accurate 8-channel, 10bit ADC with fast conversion speed and a high-performance capture compare unit with two independent 16bit timers dedicated to PWM generation offering 16bit motor control performance at 8bit costs.

The XC800 USCALE evaluation and development kit features a single evaluation platform on low-cost USB stick for XC866, XC886 and XC888 8bit MCUs, a complete tool chain support for the XC800 high-performance 8051 family of products and access to hardware signals through a 16-pin connector. It also includes a compiler and debugger and provides easy installation with demos and tutorials.

The XC800 USCALE starter kit is available for $53.73 each.
