Product details
Overview
CY8C4146LQS-S453T 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, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It delivers reconfigurable analog (2 opamps, 12-bit 1-Msps SAR ADC, 2 IDACs) and digital blocks (5 SCBs, 8 TCPWMs, CAN 2.0B with TTCAN), targeting automotive body electronics and smart sensor nodes.
For engineers reviewing the CY8C4146LQS-S453T datasheet, CY8C4146LQS-S453T pinout, CY8C4146LQS-S453T application, or CY8C4146LQS-S453T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN support, Deep Sleep current of 2.5 µA, and 54 GPIO with programmable drive modes.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable analog (CTB, SAR ADC, IDACs) and digital resources (TCPWM, SCB, CAN) via a flexible interconnect matrix. Its clock system includes ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO for multi-domain timing control.
The CAPSENSE™ subsystem uses capacitive sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, enabling robust touch operation under wet conditions. The CAN block supports time-triggered communication (TTCAN) with dedicated message RAM and error counters compliant with ISO 11898-1.

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, higher performance (112 MHz), no integrated CAPSENSE™, requires external touch controller. | Better suited for motor control or ASIL-B safety tasks; lacks native capacitive sensing capability. | Select when floating-point math or AUTOSAR stack support is required over integrated touch. |
| Renesas RL78/F14 | 16-bit RL78 core, lower power (0.6 µA Deep Sleep), limited analog (10-bit ADC, no IDACs), no CAN FD or TTCAN. | Targeted at cost-sensitive, low-complexity body nodes without advanced touch or time-triggered comms. | Select for simple relay control or basic sensor aggregation where CAPSENSE™ and TTCAN are unnecessary. |
Compared with S32K144W and RL78/F14, CY8C4146LQS-S453T uniquely combines AEC-Q100 Grade-S qualification, hardware-accelerated CAPSENSE™, TTCAN, and Deep Sleep analog retention-making it optimal for compact, touch-centric automotive human-machine interfaces requiring minimal external components.

FAQ
What is the maximum operating temperature range for CY8C4146LQS-S453T?
CY8C4146LQS-S453T is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is validated across all electrical parameters including flash endurance, analog performance, and CAN timing margins, making it suitable for under-hood and cabin-mounted automotive applications.
Does CY8C4146LQS-S453T support CAN FD or only classical CAN?
CY8C4146LQS-S453T integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) support but does not implement CAN FD. It supports bit rates up to 1 Mbps with full ISO 11898-1 compliance, message RAM, and hardware timestamping-sufficient for most body domain networks where deterministic scheduling is prioritized over bandwidth.
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 comparators. The device achieves 2.5 µA system current while maintaining touch detection capability, with wake-up interrupts generated upon threshold crossing without CPU intervention.
Is ModusToolbox™ required to develop firmware for this device?
No-ModusToolbox™ is optional and recommended for modern development, but legacy PSoC™ Creator IDE (Windows-only) fully supports CY8C4146LQS-S453T with schematic-based design, component APIs, and CAPSENSE™ tuning tools. Both environments generate identical binary output compatible with MiniProg3 and KitProg2 debuggers.
