Product details
Overview
CY8C4147AZES578XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), 12-bit 1-Msps SAR ADC, and multi-sense capacitive sensing (MSC) with >5:1 SNR-used in automotive body control modules for touch-sensitive door handles and climate panels.
For engineers reviewing the CY8C4147AZES578XQLA1 datasheet, CY8C4147AZES578XQLA1 pinout, CY8C4147AZES578XQLA1 application, or CY8C4147AZES578XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), CAPSENSE™ water tolerance, and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN in shared pins.
Technical Context
The device implements a single-layer AHB-Lite interconnect between CPU, peripherals, and memory subsystems, enabling deterministic latency for real-time automotive control. Its programmable analog includes two CTBm opamps with Deep Sleep operation and ADC input buffering, plus two low-power comparators active in Deep Sleep mode.
Digital flexibility is delivered via eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, five reconfigurable Serial Communication Blocks (SCBs), and Smart I/O logic for Boolean port-level signal conditioning-all supported by ModusToolbox™ PDL APIs and hardware-accelerated AES/SHA/TRNG cryptography.
