Product details
Overview
CY8C4147LQS-S295 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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), CAN 2.0B with TTCAN support, and eight 16-bit TCPWM modules - deployed in automotive body control modules for touch-enabled door handles and climate interfaces.
For engineers reviewing the CY8C4147LQS-S295 datasheet, CY8C4147LQS-S295 pinout, CY8C4147LQS-S295 application, or CY8C4147LQS-S295 equivalent, key selection criteria include its AEC-Q100 qualification, Deep Sleep current of 2.5 µA with operational analog, 12-bit 1-Msps SAR ADC, programmable opamps supporting ADC input buffering, and CAN/TTCAN timing compliance for distributed vehicle networks.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (CTB opamps, SAR ADC, IDACs) and digital logic (Smart I/O, TCPWM, SCB) operate concurrently under shared clock domains. Its clock system integrates ECO (4–33 MHz), PLL (48 MHz output), WCO (32 kHz), IMO (±2%), and ILO for low-power timing.
Capacitive sensing uses sigma-delta (CSD) modulation with >5:1 SNR and hardware-accelerated SmartSense tuning - enabling robust operation under moisture and EMI without host CPU intervention. The CAN block supports time-triggered communication with configurable message objects and error counters compliant with ISO 11898-1:2015.
Key Specifications

FAQ
Does CY8C4147LQS-S295 support CAN FD?
No. CY8C4147LQS-S295 integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability but does not support CAN FD data rates or extended frame formats. Its CAN block complies with ISO 11898-1:2015 for classic CAN at up to 1 Mbps, with hardware timestamping and message object filtering essential for deterministic chassis networks.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ 3.x and PSoC™ Creator 4.4 for CY8C4147LQS-S295. ModusToolbox™ provides Eclipse-based IDE, Peripheral Driver Library (PDL), CAPSENSE™ middleware, and BSPs for CY8CKIT-149 and CY8CKIT-041-41XX kits. PSoC™ Creator remains available for legacy schematic-driven design with automatic analog/digital routing.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The 12-bit SAR ADC has a single conversion core with a channel sequencer that supports automated scanning across up to 16 inputs, but it does not provide true simultaneous sampling. Each channel conversion occurs sequentially with programmable inter-channel delay, and signal averaging is applied per-channel to improve effective resolution in noisy environments.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD sensing can run autonomously in Deep Sleep mode using the internal ILO clock and dedicated low-power analog resources. The device achieves 2.5 µA system current while continuously scanning up to 16 buttons, with interrupt generation upon touch detection - enabling zero-power wake-up for automotive entry systems.
