Product details
Overview
CY8C4147AZS-S548 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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, two programmable opamps, and multi-sense capacitive sensing (MSC) with >5:1 SNR. It targets body control modules requiring robust capacitive touch, motor PWM control, and in-vehicle networking.
For engineers reviewing the CY8C4147AZS-S548 datasheet, CY8C4147AZS-S548 pinout, CY8C4147AZS-S548 application, or CY8C4147AZS-S548 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, hardware crypto acceleration (AES/SHA/TRNG), and five SCBs for concurrent I²C/SPI/UART/LIN operation - critical for automotive ECU consolidation and functional safety-aware designs.
Technical Context
The CY8C4147AZS-S548 implements a tightly coupled system-on-chip architecture where the Cortex-M0+ core interfaces via single-layer AHB-Lite to programmable analog (CTBm, SAR ADC, LP comparators), digital (TCPWM, Smart I/O), and connectivity (CAN FD, 5× SCB, I2S TX) peripherals. Its clock system integrates ECO+PLL (48 MHz), WCO, IMO (±2%), and ILO for precise timing across sleep/wake transitions.
Capacitive sensing is handled by the dedicated Multi-Sensing Converter (MSC) block with hardware-accelerated SmartSense auto-tuning and water-tolerant operation, while CAN FD enables high-bandwidth diagnostics and firmware updates at up to 5 Mbps - meeting ASAM MCD-2 MC and UDS over CAN FD requirements.
