XC822/XC836: Smart 8-bit Microcontrollers for Automotive Applications

Block diagram XC836

The XC82x-Series and the XC83x-Series is the advanced entry level for Infineon's 8-bit microcontroller family XC800 running at 24MHz. A comprehensive set of peripherals with 2KB and 8KB Flash memory is now available in low pin count packages.

Communication interfaces and fast control loops with multichannel 10-bit ADCs and PWM signal generation are featured as well as safety and low power modes. The MDU co-processor boosts up standard 8-bit processing performance. This enables more efficient and intelligent designs for low cost motor control or any kind of satellite μC applications.

With the I²C interface and the integrated capacitive touch control functionality the XC82x/XC83x expands the feature set of the XC800 family to address new areas in the automotive and motorcycle market.

XC82x-Series Touch control with advanced ROM-library MDU for additional performance and advanced control like sinusoidal commutation of motors 10-bit ADC with high accuracy over 4 channels. Fast conversion in 1μs Capture/Compare Unit (CCU6) dedicated for flexible PWM signal generation over 4 channels Direct HW-link between ADC and CCU6 for fast control loops Serial interfaces: UART, SPI, I2C Power down / wake up modes Real time clock Background E2PROM emulation XC83x-Series Touch control with advanced ROM-library Vector computer co-processor for field oriented control of sensor less motors 10-bit ADC with high accuracy over 8 channels. Fast conversion in 1μs Capture / Compare Unit (CCU6) dedicated for flexible PWM signal generation over 4 channels Direct HW-link between ADC and CCU6 for fast control loops Serial interfaces: UART, SPI, I2C Power down / wake up modes Real time clock High current pads to directly drive stepper motors or LED-displays (up to 50mA) Background E2PROM emulation The XC82x/XC83x series is fully supported by Infineon’s free tool chain DAVE™ Bench for fast time to market
