Product details
Overview
CY8C4147LQS-S253 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 (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks-enabling motor control and human-machine interface in automotive body electronics.
For engineers reviewing the CY8C4147LQS-S253 datasheet, CY8C4147LQS-S253 pinout, CY8C4147LQS-S253 application, or CY8C4147LQS-S253 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR > 5:1, Deep Sleep current of 2.5 µA, CAN 2.0B + TTCAN capability, and 54 GPIO with programmable drive strength and slew rate.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital blocks (Smart I/O, TCPWM, SCBs) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.
Its clock system integrates a 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO, with a PLL generating the 48-MHz CPU clock. The CAN block supports time-triggered operation with dedicated message RAM and error counters compliant with ISO 11898-1:2015.

FAQ
What is the maximum operating temperature grade for CY8C4147LQS-S253?
CY8C4147LQS-S253 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition Tc = +105°C and applies to the full 48-pin QFN package variant, making it suitable for under-hood and dashboard-mounted automotive modules where thermal margins are critical.
Does CY8C4147LQS-S253 support CAN FD or only classical CAN?
CY8C4147LQS-S253 implements a CAN 2.0B controller compliant with ISO 11898-1:2015 and supports Time-Triggered CAN (TTCAN), but does not support CAN FD data rates or frame formats. Its CAN block operates at up to 1 Mbps with hardware message filtering, FIFO buffering, and error confinement-meeting requirements for most body electronics networks.
Can the CAPSENSE™ subsystem operate independently during Deep Sleep mode?
Yes-the CAPSENSE™ sigma-delta sensing engine remains fully operational in Deep Sleep mode with only 2.5 µA total system current. It can autonomously scan up to 32 sensors, detect touch events, and generate interrupts or wake the CPU, enabling zero-power HMI monitoring in battery-sensitive automotive applications like keyless entry systems.
Is ModusToolbox™ required to develop firmware for this device?
No-ModusToolbox™ is optional. Firmware development is fully supported by both ModusToolbox™ (Linux/Windows/macOS) and the legacy PSoC™ Creator IDE (Windows-only). Both provide identical peripheral drivers, CAPSENSE™ configuration tools, and TCPWM APIs; ModusToolbox™ adds CI/CD integration and GitHub-hosted BSPs, while PSoC™ Creator offers schematic-based hardware design entry.
