Product details
Overview
CY8C4146AZE-S455 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, 64 KB flash, 8 KB SRAM, integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning, and a CAN 2.0B interface with TTCAN support - deployed in body control modules for touch-enabled vehicle access systems.
For engineers reviewing the CY8C4146AZE-S455 datasheet, CY8C4146AZE-S455 pinout, CY8C4146AZE-S455 application, or CY8C4146AZE-S455 equivalent, key selection criteria include its 54-GPIO count with full CAPSENSE™/analog/digital reconfigurability, Deep Sleep current of 2.5 µA with operational analog, and hardware-accelerated sigma-delta CSD engine delivering >5:1 SNR in wet environments.
Technical Context
This device integrates fixed-function and programmable digital logic-including eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals-alongside dual continuous-time opamps that operate in Deep Sleep mode and support ADC input buffering and high-drive external configurations.
The analog subsystem includes a 12-bit 1-Msps SAR ADC with channel sequencer and signal averaging, two low-power comparators, two IDACs usable on any GPIO, and a dedicated capacitance-sensing block implementing single-slope 10-bit conversion for CAPSENSE™.

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; no integrated CAPSENSE™; requires external touch controller. | Better floating-point performance for motor control algorithms; lacks hardware-accelerated capacitive sensing. | Select when real-time motor control dominates over touch interface requirements. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; integrated touch I/O but no sigma-delta CSD; no CAN FD or TTCAN. | Lower cost for basic body electronics; limited SNR (<3:1) in wet conditions; no time-triggered CAN capability. | Select for cost-sensitive entry-level modules where advanced touch robustness and TTCAN are not required. |
Compared with S32K144W and RL78/F14, CY8C4146AZE-S455 uniquely delivers certified automotive touch sensing, ultra-low deep-sleep current with active analog, and TTCAN in a single die - reducing system-level validation effort and PCB area by eliminating companion ICs.

FAQ
Is CY8C4146AZE-S455 qualified for automotive under AEC-Q100?
Yes. CY8C4146AZE-S455 is AEC-Q100 qualified for Grade-S (–40°C to +105°C), including stress testing for HTOL, TC, UHAST, and ESD per Rev G requirements. Full qualification report documentation is available upon request for OEM release sign-off.
Does this part support CAN FD or only classical CAN?
CY8C4146AZE-S455 implements CAN 2.0B only, with full support for time-triggered CAN (TTCAN) for deterministic scheduling. It does not support CAN FD data rates or extended frame formats - use Infineon's TC3xx series for CAN FD requirements.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The CSD block remains fully functional in Deep Sleep mode with 2.5 µA system current, enabling capacitive wake-up events without CPU intervention. SmartSense auto-tuning continues to adapt baseline and thresholds in real time using hardware state machines.
What development tools are officially supported?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4) IDEs. Hardware debugging uses KitProg3 or MiniProg3 programmers. CAPSENSE™ Tuner and PSoC™ Programmer CLI tools are included for production programming and factory calibration.
