Nuremberg, GermanyInfineon Technologies recently expanded its XC800 microcontroller (MCU) portfolio with two powerful 8-bit device seriesthe XC82x and XC83xwhich reduce system cost and allow for improved energy efficiency of a wide range of industrial applications.
Both series combine the market standard 8-bit 8051 CPU and peripherals optimized to enable high energy savings at low implementation costs. In addition, several of the new devices offer special features to improve the design of man-machine interfaces such as touch panels and LED display applications.
The XC82x and XC83x feature a capacitive touch sense and LED matrix controller, EEPROM emulation, 10-bit ADC, Capture Compare Unit (CCU6) 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 features for generation of high resolution PWM signals, fast ADC measurements, autonomous peripherals, and comparators for control loop and for protection. Specifically, the XC82x/XC83x MCUs provide a Capture/Compare unit (CCU6) clocked at 48MHz and a fast 16-MHz ADC with a sample time of only 125ns and a conversion time of about 820ns. The direct hardware link between ADC and CCU6 in the design ensures fast and reliable control loops. In addition, the integrated ADC limit checker realizes a digital comparator with 8-bit resolution.
The portfolio of the XC82x and XC83x series ranges from 2KB to 8KB of programmable flash and from 16-pin to 28-pin package variants, with temperature robustness up to 125°C.
Pricing: Single unit prices range from $0.55 to $1.01 in 100k quantities.
Availability: Engineering samples of the XC82x series are available, while XC83X series devices will start sampling April 2010.
