Product details
Overview
CY8C4147LQS-S463 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 (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks including two opamps and a 12-bit 1-Msps SAR ADC - deployed in automotive body control modules, smart sensors, and touch-enabled cockpit interfaces.
For engineers reviewing the CY8C4147LQS-S463 datasheet, CY8C4147LQS-S463 pinout, CY8C4147LQS-S463 application, or CY8C4147LQS-S463 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive strength and slew rate.
Technical Context
The CY8C4147LQS-S463 implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTB, SAR ADC, IDACs) and digital (TCPWM, SCB, Smart I/O) resources are configured at runtime via PSoC™ Creator or ModusToolbox™. Its clock system combines a 4–33 MHz ECO, PLL for 48-MHz system clock, 32-kHz WCO, and ±2% IMO - enabling precise timing for CAN bus synchronization and capacitive sensing acquisition.
Capacitive sensing is implemented via dedicated CSD hardware with sigma-delta modulation, delivering >5:1 SNR and hardware-accelerated SmartSense tuning - eliminating manual calibration. The CAN block supports time-triggered operation with configurable message objects, error counters, and loopback mode, meeting ISO 11898-1 requirements for deterministic automotive networking.

FAQ
Does CY8C4147LQS-S463 support CAN FD?
No. CY8C4147LQS-S463 integrates a CAN 2.0B controller with TTCAN capability but does not support CAN FD data rates or extended frame formats. Its CAN block complies with ISO 11898-1:2015 for classical CAN up to 1 Mbps, with hardware timestamping and message object filtering essential for ASIL-B–compliant systems.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN stack integration, and debug via MiniProg3 or KitProg3. ModusToolbox™ includes BSPs for CY8CKIT-149 and CY8CKIT-041-41XX kits.
Is the TRNG certified to NIST SP 800-90A/B standards?
The on-chip TRNG is implemented using analog entropy sources and digital post-processing, and is qualified for cryptographic key generation per Infineon's internal security certification process. While not individually NIST-certified, it meets the entropy and unpredictability requirements specified in SP 800-90A for DRBG seeding in automotive secure boot implementations.
Can all 54 GPIO pins be used simultaneously for CAPSENSE™?
No. CAPSENSE™ requires dedicated routing resources and shared analog buses; maximum simultaneous sensors is 32 electrodes (per datasheet Section 1.7.1). However, all 54 pins are individually configurable as CAPSENSE™ electrodes, analog inputs, or digital I/O - with dynamic reconfiguration enabled via firmware-controlled HSIOM register settings.
