Product details
Overview
CY8C4147LQE-S463 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 a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks-enabling motor control, touch HMI, and body electronics in automotive ECUs.
For engineers reviewing the CY8C4147LQE-S463 datasheet, CY8C4147LQE-S463 pinout, CY8C4147LQE-S463 application, or CY8C4147LQE-S463 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and 54 GPIOs 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 SAR ADC, two IDACs, two low-power comparators) and digital blocks (Smart I/O, TCPWM, SCBs) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode.
Its clock system integrates a 4–33 MHz ECO, PLL for 48-MHz core clock, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-supporting precise timing for CAN bit arbitration, TCPWM dead-time insertion, and CAPSENSE™ sigma-delta modulation at up to 1 MHz sampling rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic execution of automotive control loops and sensor fusion algorithms. |
| Flash / SRAM | 128 KB flash with Read Accelerator / 16 KB SRAM - supports secure bootloader storage, OTA update partitioning, and dual-bank firmware execution. |
| CAN Interface | CAN 2.0B with TTCAN support - provides time-triggered communication for synchronized actuator control and fault-tolerant diagnostics in chassis modules. |
| CAPSENSE™ Performance | Sigma-delta CSD with SNR >5:1 and water tolerance - enables reliable touch buttons/knobs in wet or condensing environments (e.g., center console, door panels). |
| Low-Power Operation | Deep Sleep current = 2.5 µA with analog active - sustains always-on capacitive wake-up detection while meeting automotive quiescent current budgets. |
| GPIO Count & Flexibility | 54 programmable GPIOs - any pin supports CAPSENSE™, analog input/output, or digital logic; drive strength and slew rate configurable per-pin for EMI control. |
| ADC Capability | 12-bit 1-Msps SAR ADC with channel sequencer and signal averaging - acquires multi-sensor analog inputs (e.g., temperature, pressure, battery voltage) with hardware-based noise reduction. |
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–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V supplies per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU logic + 5 V analog sensors). |
| P0.0–P9.7 | Programmable GPIOs | 54 total pins; each supports CAPSENSE™, analog comparator input, IDAC output, or SCB function-mapped via hardware routing matrix. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Differential pair supporting ISO 11898-2 physical layer; internal termination and slew-rate control reduce EMI in high-noise vehicle harnesses. |
| XTAL_IN / XTAL_OUT | External crystal oscillator connection | Supports 4–33 MHz ECO for precise CAN bit timing and clock calibration against WCO or IMO drift. |
| VDDD / VSSD | Digital core power/ground | Separate analog/digital supply domains minimize coupling noise into sensitive CAPSENSE™ and ADC circuits. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning across temperature/humidity/voltage variations. |
| Reconfigurable SCBs | Five serial blocks dynamically switch between I²C master/slave, SPI master/slave, UART, or LIN slave-reducing BOM count in multi-protocol gateways. |
| TCPWM Kill input | Comparator-triggered hardware kill signal disables PWM outputs within <100 ns-critical for safe motor phase shutdown during overcurrent events. |
| True Random Number Generator (TRNG) | Entropy source compliant with NIST SP 800-90B for cryptographic key generation in secure boot and firmware authentication. |
| Upward compatibility | Binary-compatible instruction set and peripheral register map with other PSoC™ 4100S Plus devices-enables scalable design reuse across product variants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and more CAN FD channels; no integrated CAPSENSE™ | Better suited for gateway or ADAS-adjacent functions requiring higher compute or networking; lacks native capacitive touch IP | Select when CAN FD, floating-point math, or Ethernet are required; add external touch controller if CAPSENSE™ needed |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade 2 (–40°C to +105°C); integrated LCD controller but no CAN or CAPSENSE™ | Targeted at cost-sensitive instrument clusters with segment LCD; no automotive network interface or touch capability | Select for simple display + button interfaces without networking or advanced sensing; requires external CAN transceiver and touch IC |
Compared with S32K144W and RL78/F14, CY8C4147LQE-S463 uniquely integrates CAPSENSE™, CAN 2.0B+TTCAN, and Deep Sleep analog operation in a single AEC-Q100 Grade-S package-making it optimal for touch-enabled body electronics where mixed-signal integration and ultra-low standby power are critical.

FAQ
What is the maximum operating temperature grade for CY8C4147LQE-S463?
CY8C4147LQE-S463 is qualified to AEC-Q100 Grade-S, specifying continuous operation from –40°C to +105°C ambient temperature. This rating covers full functionality of all peripherals-including CAPSENSE™, CAN, TCPWM, and ADC-under thermal stress conditions typical of engine bay-adjacent or dashboard-mounted automotive locations.
Does CY8C4147LQE-S463 support CAN FD?
No, CY8C4147LQE-S463 implements a CAN 2.0B controller compliant with ISO 11898-1, supporting data rates up to 1 Mbps and TTCAN features such as time-triggered transmission scheduling and synchronization. It does not support CAN FD frame format, bit rate switching, or extended data length beyond 8 bytes.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes, CAPSENSE™ CSD sensing remains fully operational in Deep Sleep mode with only 2.5 µA system current draw. The hardware sigma-delta modulator, sequencer, and SmartSense auto-calibration logic run autonomously without CPU intervention-enabling reliable wake-on-touch functionality for automotive interior applications.
How many serial communication interfaces can be configured simultaneously?
CY8C4147LQE-S463 contains five Serial Communication Blocks (SCBs), each independently configurable as I²C master/slave, SPI master/slave, UART, or LIN slave. All five can operate concurrently-for example, two CAN-linked SCBs for diagnostics, one I²C for sensor hub, one SPI for flash, and one UART for debug-without resource conflict.
