Product details
Overview
CY8C4147LQS-S293 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, integrated CAPSENSE™ capacitive touch-sensing with SmartSense auto-tuning, and a CAN 2.0B interface with time-triggered support. It targets body control modules, smart sensors, and automotive HMI systems requiring robust touch and real-time communication.
For engineers reviewing the CY8C4147LQS-S293 datasheet, CY8C4147LQS-S293 pinout, CY8C4147LQS-S293 application, or CY8C4147LQS-S293 equivalent, this device delivers verified automotive-grade mixed-signal programmability-including reconfigurable analog blocks (2 opamps, 12-bit SAR ADC), 5 SCBs for I²C/SPI/UART/LIN, 8 TCPWMs, and Deep Sleep operation at 2.5 µA-enabling rapid development of certified embedded controllers without external timing or sensing ICs.
Technical Context
The CY8C4147LQS-S293 implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable digital logic (Smart I/O, TCPWM, SCB), analog resources (CTB opamps, SAR ADC, IDACs), and system-level peripherals (CAN, WCO, TRNG). Its clock system combines a 4–33 MHz ECO, PLL, 32-kHz WCO, and ±2% IMO to support deterministic real-time execution and low-power wake-up.
Capacitive sensing is implemented via dedicated CSD hardware with >5:1 SNR and water-tolerance capability, managed by hardware-accelerated SmartSense tuning-eliminating manual calibration. The CAN block supports TTCAN for synchronized message scheduling in distributed automotive networks, while GPIOs support configurable drive modes across all 54 pins.

FAQ
What is the maximum operating temperature grade for CY8C4147LQS-S293?
CY8C4147LQS-S293 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is validated across all internal peripherals including the SAR ADC, opamps, CAN block, and CAPSENSE™ hardware-ensuring reliability in under-dash and engine-compartment environments.
Does CY8C4147LQS-S293 support CAN FD or only classical CAN?
CY8C4147LQS-S293 implements a classical CAN 2.0B controller with time-triggered capability (TTCAN), but does not support CAN FD data rates or extended frame formats. Its CAN block operates up to 1 Mbps with hardware timestamping and synchronized message scheduling-sufficient for most body electronics and chassis networks.
Can the CAPSENSE™ subsystem operate during Deep Sleep mode?
Yes-the CAPSENSE™ CSD hardware remains fully functional in Deep Sleep mode with 2.5 µA total system current. It supports low-power wake-up on touch event detection using dedicated hardware scanning logic, eliminating CPU intervention until a valid gesture or press is confirmed.
How many serial communication interfaces can be configured simultaneously on CY8C4147LQS-S293?
CY8C4147LQS-S293 includes five independent Serial Communication Blocks (SCBs), each configurable at runtime as I²C master/slave, SPI master/slave, UART, or LIN slave. All five can operate concurrently with full DMA support-enabling simultaneous communication with sensors, displays, and vehicle networks without CPU polling.
