AN0021 - AURIX™ TC4xx SMPS regulator

This application note provides guidelines and recommendations for the embedded Switched-Mode Power Supply (SMPS) of Infineon's AURIX™ TC4xx devices to ensure best efficiency and reliability. The AURIX™ TC4xx microcontroller family integrates an embedded voltage regulator for core domain voltage (EVRC). The voltage generation scheme using the EVRC regulator of AURIX™ TC4x is described in Section Core regulator operation. The parameters of the digital control block are configurable and need to be set during the start-up phase depending on application requirements. Chapter Recommended settings describe TC4xx specific parameter settings for the EVRC.

AN0049 - AURIX™ MCU: ADC accuracy assessment

This document describes the ADC accuracy testing approach for AURIX™ TC3x and TC4x microcontrollers (MCU). Infineon’s AURIX™ TC3x MCUs have EVADC and EDSADC and TC4x MCUs have TMADC and DSADC (check in a datasheet for availability in particular devices) with excellent accuracy characteristics. Although all accuracy parameters of ADCs are specified in their datasheet, sometimes they need to be checked for specific customer applications. This document describes an approach to check ADC accuracy using an arbitrary signal generator and a precise digital multimeter, widely available in every electronic laboratory.
