Product details
Overview
CY8C4146LQS-S453 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 sensing with SmartSense auto-tuning, and a CAN 2.0B block supporting time-triggered CAN (TTCAN). It targets body control modules, smart sensors, and automotive HMI systems requiring robust touch, real-time communication, and functional safety support.
For engineers reviewing the CY8C4146LQS-S453 datasheet, CY8C4146LQS-S453 pinout, CY8C4146LQS-S453 application, or CY8C4146LQS-S453 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA with operational analog, 12-bit 1-Msps SAR ADC with sequencer, and programmable analog/digital blocks enabling hardware reconfiguration without PCB changes.
Technical Context
The device integrates a dedicated CAN 2.0B controller with TTCAN compliance for deterministic timing in distributed automotive networks, alongside eight 16-bit TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals for motor control safety. Its clock system includes a 4–33 MHz ECO, PLL for 48-MHz core clock, and independent 32-kHz WCO/ILO oscillators enabling precise low-power timing.
Capacitive sensing uses a sigma-delta (CSD) architecture delivering >5:1 SNR and water tolerance, managed by hardware-accelerated SmartSense tuning - eliminating manual calibration. The two continuous-time opamps operate in Deep Sleep mode and support ADC input buffering, while dual IDACs enable self-capacitance and mutual-capacitance sensing on any GPIO.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz, 1 MB flash, no integrated CAPSENSE™, includes Ethernet MAC | Better suited for gateway/routing tasks; lacks hardware capacitive sensing acceleration | Select when higher compute throughput or Ethernet connectivity is required over touch integration. |

FAQ
Does CY8C4146LQS-S453 support CAN FD?
No. CY8C4146LQS-S453 implements CAN 2.0B with time-triggered extensions (TTCAN) but does not support CAN FD data rates or flexible data-length frames. Its CAN controller complies with ISO 11898-1:2015 for classical CAN and time-triggered scheduling only.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ (v3.x+) and legacy PSoC™ Creator v4.4 for CY8C4146LQS-S453. ModusToolbox™ provides Peripheral Driver Library (PDL), CAPSENSE™ middleware, and BSPs for kits like CY8CKIT-149. Debug requires KitProg3 or MiniProg3 programmers.
Is the 12-bit SAR ADC capable of simultaneous sampling across multiple channels?
No. The 12-bit SAR ADC features a single conversion core with a channel sequencer and hardware averaging, but lacks true simultaneous sampling. Multi-channel acquisition is performed sequentially with programmable inter-channel delay and up to 16-sample hardware averaging per channel.
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. Wake-up events (e.g., touch detection) trigger interrupt requests without waking the CPU, maintaining system current below 3 µA.
