ThePSOC™ HVMS 128K, 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.
