    • Implements advanced proximity sensing: wake-on-approach, liquid level detection, and IR sensor replacement

  • Reduced system costs

    PSOC™ Automotive 4 reduces system cost with programmable digital blocks, programmable analog blocks, CAPSENSE™ and LIN slave to:

    • Create custom AFEs for sensors and add sophisticated user interfaces

    • Communicate to car network with integrated LIN

    • Slave controllers

    • PSOC™ Creator enables easy integration of multiple ICs and system interfaces into one PSOC™

  • Reliable operation in harsh automotive EM environment

    • Zero false touches reported by the touch sensors in harsh automotive environment

    • Reduces radiated emissions (RE) by easily modifying CAPSENSE™ component parameters in PSOC™ Creator IDE

    • Complies with standard emission and immunity specifications like CISPR 25, ISO 11452, IEC 61967 and IEC 62132

  • Temperature ranges

    • Temperature A-Grade: -40°C to +85°C

    • Temperature S-Grade: -40°C to 105°C

  • Intelligent analog

    PSOC™ 4100 family adds intelligent analog integration through programmable analog blocks. Programmable analog blocks are hardware modules that include analog-to-digital converters (ADCs), digital-to-analog converters (DACs), low-power comparators, and operational amplifiers (opamps). Programmable analog block enable you to customize your analog front end to interface to virtually any analog sensor.
