Infineon PSOC™ 4 HVMS-64K

The PSOC™ 4 HVMS-64K, part of the PSOC™ 4 HV mixed-signal (MS) series, is a fully integrated, programmable embedded system designed for automotive HMI, body, and powertrain applications. It combines an Arm^® Cortex^®-M0+ processor with programmable analog and digital blocks, featuring a 12-bit SAR ADC, 5th-gen CAPSENSE™ for capacitive sensing, digital peripherals like PWMs, serial communication interfaces, and an integrated LIN PHY. Its high-voltage subsystem enables direct operation from a 12 V car battery, making it ideal for robust automotive solutions. This is also available with 128K
