Peripheral Highlights Direct hardware link between Analog-Digital Converter (ADC) and Capture/Compare Unit (CCU6) The Infineon CCU6 units consist of a T12 timer block with three capture/compare channels and a T13 timer block with one compare channel. The T12 channels can generate up to six PWM signals or accept up to six capture triggers. The T12 channels can be used to control up to three half-bridges with automatic dead-time generation. They can jointly generate control signal patterns to drive AC motors or inverters. Sinusoidal or space vector modulation can be easily implemented....

T2CCU Capture/Compare Unit The T2CCU (Timer 2 Capture/Compare Unit) is an add-on block to the standard timer two unit. Control is available in the T2CCU to individually select either the timer 2 or its own Capture/Compare Timer (CCT) as the time base for each of its 16-bit capture/compare channels. The T2CCU can be used for various digital signal generation and event capturing operations such as pulse generation, pulse width modulation, pulse width measurement etc. Target applications include various automotive control as well as industrial applications like frequency generation,...

Peripheral Highlights LED Touch Sense Unit The LED Touch Sense Unit is featured with the Xc82x and XC83x series. This unit integrates capacitive touch control and the operation of an LED matrix used for displays in low pin-count devices via time-multiplexed operation. It encompasses a combination of features often demanded – e.g. by home appliance, automotive or consumer HMI designs. Touch Control Unit External or internal pull-up resistor Automatic pad selection logic for auto-scan function Adjustable discharge time Adjustable saturation/overflow behavior of oscillation pulse counter...

Math and Control ROM-Library The math and control code ROM library featured with the XC82x and XC83x series offers various DSP functionalities, such as the PI-controller, SIN and COS or Cartesian-to-polar transformation. It contains all algorithms required to perform one of the most ambitious control schemes – field-oriented motor control – with an 8-bit microcontroller. yamax. yamin.

XC800 Safety Solutions IEC 60730/Class B Certification Infineon offers SafeDrive, a flexible and cost-sensitive approach to class B compliance using single-channel architecture with a periodic self-test. SafeDrive consists of a VDE-certified free software library containing self-test routines that covers six of the ten components required by class B. The remaining four are application-specific and have to be implemented in the application code. Thanks to the safety features of XC800, compliance is possible with minimal CPU/ memory overhead. Class B compliance is mandatory in Europe. Voltage...

Safety Watchdog CIC61508 Safety Systems require an independent watchdog which implements a robust monitoring channel for main MCU supervision in ISO26262 and IEC61508 compliant safety applications. With its small footprint the CIC61508 is a space/cost effective choice to support applications like airbag, steering, braking, etc. SIL Supporting Key Features Internal Test Scheduler / Sequencer ––Generates a sequence of test requests with specific data and checks the response against a static table Supply Voltage Monitor ––Capable of detecting under- and overvoltage of the supply to the...

XC800 A-Family – Dedicated to Automotive Applications The XC800 A-Family is Infineon’s automotive 8-bit family that addresses low-end body, safety and powertrain applications for 2-/3-/4-wheelers. A set of strong peripheral features along with high quality standards has already positioned the 8-bit microcontroller ahead of the competition in demanding applications such as automotive motor control. This high standard of performance and quality is now further enhanced with the introduction of the 150°C Series; the same high-performance 8051 microcontroller, now “Grade 0” qualified at 150°C...
