Product details
Overview
CY8C4146PVS-S432T from Infineon is an AEC-Q100 Grade 2 automotive-qualified 32-bit PSoC™ Automotive 4100S microcontroller featuring a 48 MHz Arm® Cortex®-M0+ CPU, 64 KB flash, 8 KB SRAM, integrated CAPSENSE™ capacitive sensing, and three reconfigurable serial communication blocks (SCB) supporting I²C/SPI/UART/LIN slave modes. It operates from 1.71 V to 5.5 V and supports Deep Sleep mode with 2.5 µA system current.
For engineers reviewing the CY8C4146PVS-S432T datasheet, CY8C4146PVS-S432T pinout, CY8C4146PVS-S432T application, or CY8C4146PVS-S432T equivalent, key selection criteria include AEC-Q100 S-grade (–40°C to +105°C) qualification, on-chip 12-bit 1-Msps SAR ADC with sequencer, dual opamps with Deep Sleep operation, programmable TCPWM blocks for motor control kill signals, and CAPSENSE™ CSD with >5:1 SNR and water tolerance.
Technical Context
The device implements a tightly coupled mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTBm opamps, SAR ADC, IDACs, comparators) and digital (TCPWM, SCB, PLD) resources are configured via hardware routing and ModusToolbox™ PDL APIs. All analog peripherals retain functionality in Deep Sleep mode.
Its clock system integrates IMO (48 MHz), ILO (32.768 kHz), and WCO support; five TCPWM blocks provide center-aligned PWM with comparator-triggered kill inputs for functional safety-critical motor drive timing; three SCBs enable concurrent I²C master, SPI slave, and UART debug interfaces without resource conflict.
