Product details
Overview
CY8C4146LQE-S263 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 (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks - deployed in automotive body control modules for touch-enabled door handles and climate interface panels.
For engineers reviewing the CY8C4146LQE-S263 datasheet, CY8C4146LQE-S263 pinout, CY8C4146LQE-S263 application, or CY8C4146LQE-S263 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR >5:1 with water tolerance, 2.5 µA Deep Sleep current, CAN 2.0B + TTCAN compliance, and 54 GPIO with programmable drive strength and slew rate.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit 1-Msps SAR ADC, two IDACs) and digital logic (Smart I/O, TCPWM, SCBs) operate under hardware-configured routing. Its clock system integrates a 4–33 MHz ECO, PLL for 48-MHz core clock, 32-kHz WCO, and ±2% IMO - enabling deterministic timing for motor control PWM and LIN slave response.
The CAPSENSE™ subsystem uses capacitance-sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, delivering >5:1 SNR and robust operation under wet conditions. The CAN block supports time-triggered communication with dedicated message RAM and error counters, meeting ISO 11898-1 requirements for body electronics messaging integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - enables real-time execution of sensor fusion and LIN/CAN protocol stacks without external co-processors. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - sufficient for dual-bank firmware updates and CAPSENSE™ calibration data storage. |
| Capacitive Sensing | CAPSENSE™ CSD with SmartSense auto-tuning, SNR >5:1 - eliminates manual electrode tuning and maintains reliability during condensation or splash exposure. |
| CAN Interface | CAN 2.0B compliant with TTCAN support - provides deterministic scheduling for safety-critical body control messages (e.g., seat position, mirror fold). |
| Power Modes | Deep Sleep at 2.5 µA (digital) with active analog - sustains touch wake-up detection and CAN bus monitoring without battery drain in parked vehicle state. |
| GPIO | 54 pins, all CAPSENSE™/analog/digital configurable, programmable drive/slew - enables single-chip integration of touch buttons, LED drivers, and LIN transceiver interface. |
| Temperature Range | AEC-Q100 Grade-S: –40°C to +105°C - qualified for under-hood and cabin-mounted automotive control units. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0 | I/O power supply | Supplies 1.71–5.5 V to Port 0–3 GPIOs; independent regulation allows mixed-voltage interface (e.g., 3.3 V MCU logic + 5 V analog sensors). |
| P0[0]–P0[7] | Programmable GPIO | Support CAPSENSE™ CSD, analog input, UART TX/RX, or TCPWM output - configured per-pin in PSoC™ Creator without hardware change. |
| CAN_TX / CAN_RX | Dedicated CAN physical layer interface | Direct connection to external CAN transceiver (e.g., TJA1042); internal termination and filtering reduce BOM count and PCB area. |
| XTAL_IN / XTAL_OUT | External crystal oscillator terminals | Support 4–33 MHz ECO for precise clock source; required for CAN bit timing accuracy and LIN baud rate stability. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC functionality and low-power wake-up timing independent of main clock domain. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual electrode parameter adjustment and ensures consistent button response across temperature/humidity variations. |
| Reconfigurable SCBs | Five serial blocks dynamically switch between I²C master/slave, SPI master/slave, UART, or LIN slave - enabling flexible peripheral expansion without pin remapping or firmware rewrite. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed message latency and deterministic bandwidth allocation - critical for synchronized actuator control in body domain ECUs. |
| Deep Sleep with active analog | 2.5 µA system current while maintaining CAPSENSE™ wake-up detection and CAN bus monitoring - extends battery life in always-on vehicle entry systems. |
| Programmable Smart I/O | Boolean logic applied directly to GPIO inputs/outputs without CPU intervention - offloads debouncing, edge detection, and signal conditioning from firmware. |
Applications
| Automotive Door Handle Interface | Climate Control Panel |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147LQE-S473 | Same PSoC™ 4100S Plus family, but with 256 KB flash and 32 KB SRAM; identical pinout and peripheral set. | Required when firmware image size exceeds 128 KB or runtime data buffers exceed 16 KB - e.g., OTA update stack + secure boot + logging. | Select for future-proofing firmware growth or adding cryptographic libraries without changing PCB layout. |
| SPC560B50L5 | 32-bit Power Architecture SPC560B MCU; no integrated CAPSENSE™; requires external touch controller; CAN FD capable. | Suitable for high-speed chassis networks requiring CAN FD bandwidth (>1 Mbps), but adds BOM cost and design complexity for touch interfaces. | Choose only if CAN FD is mandatory and touch sensing is implemented externally via dedicated IC or overlay. |
Compared with CY8C4146LQE-S263, CY8C4147LQE-S473 offers scalable memory headroom within identical footprint and qualification, while SPC560B50L5 trades integrated capacitive sensing for CAN FD throughput - making the former ideal for cost-sensitive body electronics and the latter for chassis-domain gateways.

FAQ
Is CY8C4146LQE-S263 qualified for automotive use?
Yes. CY8C4146LQE-S263 is AEC-Q100 qualified to Grade-S (–40°C to +105°C), with full documentation including stress test reports, failure analysis summaries, and qualification certificates available through Infineon's official support portal. It meets automotive reliability standards for humidity, thermal cycling, and ESD immunity.
Does it support CAN FD or only classical CAN?
CY8C4146LQE-S263 implements CAN 2.0B only, with full TTCAN support for time-triggered scheduling. It does not support CAN FD data rates or extended frame formats. For CAN FD requirements, consider Infineon's AURIX™ TC3xx series or external CAN FD controller interfacing via SPI.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD sensing remains fully active in Deep Sleep mode with 2.5 µA total system current. Hardware-accelerated SmartSense continues automatic recalibration, and wake-up interrupts trigger on touch events without CPU involvement - essential for low-power vehicle entry systems.
What development tools are officially supported?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN register setup, and debug via MiniProg3 or KitProg3. Third-party tools like Keil MDK and IAR Embedded Workbench are supported via PDL-based projects.
