Product details
Overview
CY8C4146AZS-S265 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 sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks including two opamps and a 12-bit 1-Msps SAR ADC. Used in automotive body control modules requiring robust touch interface and real-time motor timing.
For engineers reviewing the CY8C4146AZS-S265 datasheet, CY8C4146AZS-S265 pinout, CY8C4146AZS-S265 application, or CY8C4146AZS-S265 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN compliance, Deep Sleep current ≤2.5 µA, and GPIO flexibility across 54 pins with programmable drive modes.
Technical Context
The CY8C4146AZS-S265 implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable digital logic (Smart I/O, TCPWM, SCB), configurable analog resources (CTB opamps, SAR ADC, IDACs), and dedicated peripherals (CAN 2.0B, CSD block). Its clock system combines a 4–33 MHz ECO, PLL for 48-MHz core clock, and low-power oscillators (WCO, ILO) enabling precise timing across sleep/wake transitions.
Capacitive sensing is implemented via a dedicated capacitance-sigma-delta (CSD) block delivering >5:1 SNR and water tolerance, supported by hardware-accelerated SmartSense tuning and software APIs in ModusToolbox™ and PSoC™ Creator. The CAN block supports time-triggered operation with dedicated message RAM and error counters compliant with ISO 11898-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables deterministic real-time control with Thumb-2 instruction set and NVIC interrupt handling. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - supports firmware updates, bootloader storage, and real-time data buffering without external memory. |
| Analog ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with signal averaging - delivers high-resolution sensor acquisition with noise suppression for automotive sensors. |
| CAPSENSE™ | Capacitance-sigma-delta (CSD) block with >5:1 SNR and automatic SmartSense tuning - enables reliable touch buttons/sliders under wet conditions and varying environmental noise. |
| CAN Interface | CAN 2.0B with TTCAN support, dedicated message RAM, and hardware timestamping - meets automotive network timing determinism and fault confinement requirements. |
| Power Range | 1.71 V to 5.5 V supply, Deep Sleep current ≤2.5 µA - allows direct battery connection and ultra-low-power wake-on-event operation in always-on nodes. |
| GPIO Count | 54 programmable pins, all support CAPSENSE™, analog, or digital functions with configurable drive strength/slew rate - eliminates external level shifters and simplifies PCB routing. |

Pinout & Package
CY8C4146AZS-S265 is housed in a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully configurable via PSoC™ Creator or ModusToolbox™; no fixed peripheral pin assignments - all 54 GPIOs are multiplexed across physical pins depending on design configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Independent 1.71–5.5 V supplies per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU core + 5 V sensor interface). |
| VDDD / VDDA | Digital/analog core supply | Separate regulated inputs reduce coupling noise between digital switching and precision analog acquisition paths. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for accurate timing; required for CAN bit-rate stability and USB-free clock derivation. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC operation and low-power wake-up timing independent of main clock domain. |
| SWDCK / SWDIO | ARM Serial Wire Debug interface | Two-pin debug interface supports full programming, breakpointing, and real-time trace without dedicated JTAG pins. |
| P0[0]–P9[7] | Programmable GPIO bank terminals | Each pin supports CAPSENSE™, analog input/output, digital logic, or SCB/CAN function - configured at design time, not runtime. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual threshold tuning and maintains button sensitivity across temperature/humidity drift. |
| Reconfigurable SCBs | Five serial blocks dynamically assignable as I²C, SPI, UART, or LIN slave - reduces BOM count and enables protocol migration without hardware change. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed message transmission windows - satisfies ASAM MCD-2 MC and AUTOSAR COM stack timing constraints. |
| Deep Sleep analog retention | Opamps, comparators, and CSD block remain active at ≤2.5 µA system current - enables continuous touch monitoring or sensor wake-up without full MCU restart. |
| Programmable Smart I/O | Boolean logic on port inputs/outputs (AND/OR/XOR) with event chaining - implements hardware-based debounce, edge detection, or state machines without CPU intervention. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz, 1 MB flash, no integrated CAPSENSE™, requires external touch controller | Targeted at higher-performance motor control; lacks on-die capacitive sensing hardware acceleration | Select when floating-point math or larger code footprint dominates over touch integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, 512 KB flash, built-in touch I/O but no sigma-delta CSD block or SmartSense | Lower cost for basic touch + CAN; SNR limited to ~3:1, no water-tolerance certification | Select for non-critical interior panels where cost sensitivity outweighs environmental robustness. |
Compared with NXP S32K144W and Renesas RL78/F14, CY8C4146AZS-S265 uniquely integrates CAPSENSE™ CSD hardware with >5:1 SNR and SmartSense, enabling certified wet-condition touch operation in a single AEC-Q100 Grade-S chip - reducing system BOM, layout complexity, and qualification effort.

FAQ
Does CY8C4146AZS-S265 support CAN FD?
No. CY8C4146AZS-S265 implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD frame format, data rates above 1 Mbps, or flexible data-length payloads. For CAN FD, consider Infineon's AURIX™ TC3xx family or later-generation PSoC™ 6 devices with dual-core CAN FD controllers.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN message setup, and debug via MiniProg3 or KitProg3. Third-party tools like Keil MDK and IAR Embedded Workbench are supported via CMSIS-Pack integration.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The SAR ADC has a single conversion engine with a channel sequencer supporting up to 32 inputs, but it performs conversions sequentially-not simultaneously. True simultaneous sampling requires external parallel ADCs or devices with multiple independent SAR cores, such as Infineon's XMC7000 series.
Can GPIO pins be used for both CAPSENSE™ and analog ADC input at the same time?
No. While any GPIO pin can be assigned to CAPSENSE™ or analog ADC function in a given design, they cannot operate in both roles concurrently on the same pin. The analog multiplexer routes each pin to either the CSD block or the SAR ADC input path-not both-due to shared internal analog bus architecture.
