Product details
Overview
CY8C4146AZE-S275 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, and integrated CAPSENSE™ capacitive touch-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 proximity-sensing door handles and interior touch interfaces.
For engineers reviewing the CY8C4146AZE-S275 datasheet, CY8C4146AZE-S275 pinout, CY8C4146AZE-S275 application, or CY8C4146AZE-S275 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR >5:1, Deep Sleep current of 2.5 µA, and CAN 2.0B/TTCAN compliance for safety-critical vehicle subsystems.
Technical Context
This device implements a mixed-signal SoC architecture where analog and digital resources are programmable and automatically routed. Its dual opamp blocks support ADC input buffering and comparator modes while operating in Deep Sleep; the 12-bit SAR ADC delivers 1-Msps sampling with channel sequencing and signal averaging.
The CAN block supports time-triggered operation with dedicated message RAM and error counters, and the TCPWM blocks provide quadrature decoding, kill-signal triggering via comparators, and center-aligned PWM - enabling motor control and timing-critical actuation in automotive ECUs.

Use Value: On-die CSD hardware processes 20+ electrodes simultaneously at <10 ms scan rate - eliminates external touch controller IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and FlexCAN FD; lacks integrated CAPSENSE™ | Targets gateway and ADAS domain controllers requiring higher compute and FD bandwidth; not optimized for touch-centric nodes | Select when CAN FD, floating-point math, or Ethernet are mandatory; avoid if CAPSENSE™ integration and cost-sensitive BOM are priorities |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or CAPSENSE™ | Suitable for basic lighting or relay control; limited analog capability and no hardware touch engine | Choose for ultra-low-cost, low-complexity body electronics where touch is absent and CAN speed ≤1 Mbps suffices |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4146AZE-S275 uniquely integrates CAPSENSE™ with automotive CAN and Deep Sleep analog operation - delivering lowest BOM count and fastest development cycle for touch-enabled ECU nodes.

FAQ
What is the maximum operating temperature grade for CY8C4146AZE-S275?
CY8C4146AZE-S275 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per stress-test conditions defined in the AEC-Q100 standard and applies to the full 48-pin QFN package variant. Thermal derating is not required within this range when PCB layout follows Infineon's recommended copper pour and thermal pad guidelines.
Does CY8C4146AZE-S275 support CAN FD?
No, CY8C4146AZE-S275 implements a classical CAN 2.0B controller with TTCAN extensions but does not support CAN FD data rates or frame formats. Its CAN block operates up to 1 Mbps with time-triggered scheduling, message RAM, and hardware error counters - sufficient for body domain networks but not for high-bandwidth ADAS or gateway applications requiring FD throughput.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes, CAPSENSE™ CSD sensing can execute in Deep Sleep mode using the internal ILO clock and dedicated low-power analog resources. The device maintains 2.5 µA system current while scanning up to 16 electrodes, with wake-up interrupt generation upon threshold crossing - enabling battery-powered proximity detection without full MCU wake.
Is ModusToolbox™ required for development with CY8C4146AZE-S275?
No, ModusToolbox™ is optional. CY8C4146AZE-S275 is fully supported by both ModusToolbox™ (for modern, IDE-neutral workflows) and the legacy PSoC™ Creator IDE (Windows-only, schematic-based design). Both environments provide identical peripheral drivers, CAPSENSE™ configuration tools, and debug capabilities via MiniProg3 or KitProg3 programmers.
