Infineon Technologies PSOC™ 4 HV MS-64K/128K Automotive Microcontrollers
Infineon Technologies PSOC™ 4 HV MS-64K/128K Automotive Microcontrollers (MCUs) belong to the PSOC 4 HV Mixed Signal (MS) series. These MCUs are a combination of a microcontroller with a 12-bit SAR ADC, a 5th-generation Multi-Sense Converter (MSC) block supporting capacitive sensing (CAPSENSE™). The PSOC™ 4 HV MS-64K/128K MCUs feature an Arm® Cortex®-M0+ processor with programmable and reconfigurable analog and digital blocks. These MCUs support functional safety levels of ASIL-B according to ISO 26262 and are AEC-Q100 qualified.
The PSoC™ 4 HV MS-64K/128K MCUs feature up to 60mA regulator current, thermal shutdown function, and two low-power comparators that operate in deep sleep low-power mode. These MCUs are used in applications such as PTC heaters, liquid level sensing, car access, automotive HMI, and Wheatstone bridge sensors.
