Product details
Overview
CY8C4147AZE-S475 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and body electronics.
For engineers reviewing the CY8C4147AZE-S475 datasheet, CY8C4147AZE-S475 pinout, CY8C4147AZE-S475 application, or CY8C4147AZE-S475 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and programmable analog/digital routing for mixed-signal system integration.
Technical Context
The device implements a tightly coupled MCU subsystem with dual-clock domain operation: the IMO (±2%) and PLL-derived 48-MHz core clock feed CPU and digital peripherals, while independent WCO (32 kHz) and ILO (32 kHz) clocks enable low-power timing and RTC functions. All analog blocks-including two opamps, 12-bit SAR ADC (1 Msps), and two IDACs-are fully operational in Deep Sleep mode.
Its programmable architecture uses Smart I/O logic blocks for Boolean port-level signal conditioning and SCBs that dynamically switch between I²C/SPI/UART/LIN slave modes at runtime. The CAN block supports time-triggered operation with configurable message objects and hardware timestamping, meeting ASAM MCD-2 MC and ISO 11898-1 requirements for deterministic automotive networks.

FAQ
What is the maximum operating temperature grade for CY8C4147AZE-S475?
CY8C4147AZE-S475 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per stress test conditions defined in AEC-Q100-002 and validated across all silicon lots and package variants, making it suitable for under-hood and cabin-mounted automotive ECUs.
Does CY8C4147AZE-S475 support CAN FD or only classical CAN?
CY8C4147AZE-S475 implements a CAN 2.0B controller with time-triggered CAN (TTCAN) support, but does not support CAN FD data rates or frame formats. It complies fully with ISO 11898-1:2015 for classical CAN at up to 1 Mbps, including hardware message filtering, transmit buffering, and error confinement.
Can the on-chip CAPSENSE™ replace mechanical buttons in automotive interior applications?
Yes-CY8C4147AZE-S475's CAPSENSE™ CSD engine delivers >5:1 SNR with hardware-based water tolerance and SmartSense auto-tuning, enabling reliable detection through laminated glass, plastic overlays, and wet surfaces. It has been deployed in production automotive HVAC and infotainment panels certified to ISO 10605 ESD and IEC 61000-4-3 radiated immunity.
Is ModusToolbox™ required to develop firmware for this device?
No-ModusToolbox™ is optional. Firmware can be developed using PSoC™ Creator (legacy Windows IDE) or standard Arm® GCC toolchains with Infineon's Peripheral Driver Library (PDL). ModusToolbox™ adds CI/CD integration, BSPs for evaluation kits, and middleware like CAPSENSE™ Tuner, but is not mandatory for basic firmware builds or production programming.
