Product details
Overview
CY8C4147LQSS285XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus programmable system-on-chip featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning, and a CAN 2.0B controller. It serves as a reconfigurable embedded controller for body electronics, door modules, and touch-enabled human-machine interfaces.
For engineers reviewing the CY8C4147LQSS285XQLA1 datasheet, CY8C4147LQSS285XQLA1 pinout, CY8C4147LQSS285XQLA1 application, or CY8C4147LQSS285XQLA1 equivalent, this device supports concurrent analog/digital configuration, deep-sleep operation at 2.5 µA, and hardware-accelerated capacitive sensing with >5:1 SNR-critical for automotive interior touch panels and proximity detection systems.
Technical Context
The CY8C4147LQSS285XQLA1 integrates a fixed-function CAN 2.0B block supporting time-triggered CAN (TTCAN), eight 16-bit TCPWM blocks with comparator-based kill signal triggering for motor control safety, and five reconfigurable serial communication blocks (SCBs) supporting I²C/SPI/UART/LIN slave modes. Its analog subsystem includes two continuous-time opamps with Deep Sleep operation, a 12-bit 1-Msps SAR ADC with channel sequencer and averaging, and dual IDACs for CAPSENSE™ or current-source applications.
Timing is managed by multiple clock sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-with PLL enabling precise 48-MHz system clock generation. The device implements true random number generation (TRNG) for cryptographic key derivation and supports LCD segment drive on GPIOs without external drivers.

FAQ
What is the maximum operating temperature grade for CY8C4147LQSS285XQLA1?
This device is rated Grade-S per AEC-Q100, supporting continuous operation from –40°C to +105°C ambient temperature. It is validated for use in passenger compartment applications such as center consoles and door panels where thermal stress exceeds standard commercial-grade limits.
Does CY8C4147LQSS285XQLA1 support CAN FD?
No. This part implements CAN 2.0B only, with TTCAN support for time-triggered messaging. It does not include CAN FD physical layer or protocol enhancements such as variable bit rates or extended data length. For CAN FD, consider Infineon's AURIX™ or SAK-TC3xx families.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The CSD block remains active in Deep Sleep mode with analog subsystem powered, enabling low-power wake-on-touch functionality. Current consumption is typically 15–25 µA depending on scan rate and electrode count, while digital logic remains halted until interrupt assertion.
Is PSoC™ Creator still supported for this device?
Yes. Infineon continues to provide full PSoC™ Creator 4.x toolchain support-including component libraries, debug probe integration (MiniProg3/KitProg2), and CAPSENSE™ Tuner-for CY8C4147LQSS285XQLA1. Migration paths to ModusToolbox™ are documented but optional.
