Product details
Overview
CY8C4146LQE-S453T 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 >5:1 SNR. It includes five reconfigurable SCBs (I²C/SPI/UART/LIN), a CAN 2.0B block with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and body electronics.
For engineers reviewing the CY8C4146LQE-S453T datasheet, CY8C4146LQE-S453T pinout, CY8C4146LQE-S453T application, or CY8C4146LQE-S453T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and 54 GPIO with programmable drive strength and slew rate.
Technical Context
This device implements a mixed-signal SoC architecture where analog and digital resources-including two continuous-time opamps, a 12-bit 1-Msps SAR ADC, dual IDACs, and low-power comparators-are fully reconfigurable via hardware routing. Its programmable Smart I/O blocks enable Boolean logic on GPIO signals without CPU intervention.
The clock system integrates multiple sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO, with a PLL generating the 48-MHz core clock. The CAN block supports time-triggered operation for deterministic communication in safety-critical automotive subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC; no integrated CAPSENSE™ | Better suited for high-performance motor control with FPU; lacks native capacitive touch IP | Select when floating-point computation or Ethernet connectivity is required over touch integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; 256 KB flash; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or TTCAN | Lower cost for basic body electronics; limited analog flexibility and no sigma-delta CAPSENSE™ | Select for cost-sensitive, non-touch applications where CAN 2.0B suffices and mixed-signal programmability is not needed. |
Compared with S32K144W and RL78/F14, CY8C4146LQE-S453T uniquely combines AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with SmartSense, TTCAN, and reconfigurable analog/digital fabric-making it optimal for touch-enabled, safety-aware automotive nodes where hardware-level flexibility reduces BOM count and design cycle time.

FAQ
Does CY8C4146LQE-S453T support CAN FD?
No. This device implements a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability but does not support CAN FD data rates or extended frame formats. For CAN FD, consider Infineon's AURIX™ TC3xx family or later-generation PSoC™ devices with CAN FD blocks.
What development tools are officially supported for this part?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator v4.4 for CY8C4146LQE-S453T. Hardware debugging requires MiniProg3 or KitProg3; the CY8CKIT-149 prototyping kit provides full pin access and CAPSENSE™ evaluation capability.
Is the 12-bit SAR ADC capable of simultaneous sampling?
Yes. The 12-bit SAR ADC supports hardware channel sequencing with up to 16 channels and includes a built-in signal averaging function. While it uses a single ADC core, the sequencer and DMA enable deterministic multi-channel acquisition with minimal CPU overhead.
How is CAPSENSE™ calibrated across temperature and voltage variations?
CY8C4146LQE-S453T uses SmartSense™-a hardware-accelerated auto-tuning algorithm that dynamically adjusts IDAC current, scan resolution, and baseline tracking parameters in real time, ensuring stable button detection across –40°C to +105°C and 1.71–5.5 V supply range without host firmware intervention.
