Product details
Overview
CY8C4147LQE-S473T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with >5:1 SNR. It includes five reconfigurable SCBs (I²C/SPI/UART/LIN), a CAN 2.0B block with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and body electronics.
For engineers reviewing the CY8C4147LQE-S473T datasheet, CY8C4147LQE-S473T pinout, CY8C4147LQE-S473T application, or CY8C4147LQE-S473T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and 54 GPIO with programmable drive strength and slew rate.
Technical Context
The device implements a tightly integrated mixed-signal SoC architecture: the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit 1-Msps SAR ADC, two IDACs, two low-power comparators) and digital resources (TCPWM, SCB, CAN, Smart I/O) operate concurrently under shared clock and power domains. All analog peripherals remain functional in Deep Sleep mode.
Its clock system combines a 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO, with a PLL generating the 48-MHz system clock. The CAN block supports time-triggered communication via TTCAN, enabling deterministic message scheduling for safety-critical automotive subsystems.
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. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - supports complex firmware with bootloader, diagnostics, and CAPSENSE™ tuning data storage. |
| Capacitive Sensing | CAPSENSE™ CSD with >5:1 SNR and SmartSense auto-tuning - delivers robust touch performance under moisture, gloves, and EMI without manual calibration. |

| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for high-accuracy timing - used for CAN bit timing, TCPWM synchronization, and clock redundancy. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC, low-power wake-up, and CAN timestamping independent of main clock domain. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates factory tuning and field recalibration - reduces BOM cost and production test time. |
| Deep Sleep with active analog | 2.5 µA system current while opamps, comparators, and SAR ADC remain operational - enables ultra-low-power capacitive wake-up and battery voltage monitoring. |
| Reconfigurable SCBs | Five serial blocks dynamically assignable as I²C master/slave, SPI master/slave, UART, or LIN slave - simplifies multi-protocol gateway design without additional ICs. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed message latency and jitter <1 µs - satisfies ASIL-B timing requirements in lighting and seat control modules. |
| Programmable drive strength & slew rate | Configurable per-pin output drive (2–20 mA) and edge rate - mitigates EMI in noisy automotive environments and matches legacy load requirements. |
Applications
| Automotive Door Module | 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 |
|---|---|---|---|
| CY8C4147AZI-S433 | Same PSoC™ 4100S Plus family, but 40-pin QFN, 64 KB flash, 8 KB SRAM, no CAN block. | Lacks CAN 2.0B/TTCAN; suitable only for non-networked touch HMI or standalone motor control. | Select when CAN is unnecessary and footprint/cost reduction outweighs memory and peripheral scalability. |
| SPC560B50L5 | 32-bit Power Architecture MCU, 64 MHz, 512 KB flash, 48 KB RAM, dual CAN, but no integrated CAPSENSE™ or programmable analog. | Requires external touch controller and signal-conditioning circuitry; higher power in sleep modes (≥15 µA). | Choose for high-speed engine management where CAN bandwidth and deterministic interrupt latency exceed PSoC™ 4100S Plus capabilities. |
Compared with CY8C4147AZI-S433, this part adds CAN and doubles memory; versus SPC560B50L5, it trades raw compute for integrated analog/touch and ultra-low Deep Sleep current - ideal for cost-sensitive, space-constrained automotive body electronics.

FAQ
Does CY8C4147LQE-S473T support CAN FD?
No. This device implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD data rates or extended frame formats. For CAN FD applications, consider Infineon's AURIX™ TC3xx family or later-generation PSoC™ 6 devices with CAN FD controllers.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD scanning can run autonomously in Deep Sleep mode using the internal ILO clock and dedicated low-power hardware blocks. Wake-up events trigger CPU exit from Deep Sleep with full context retention in SRAM.
What development tools are officially supported?
Infineon officially supports ModusToolbox™ (Eclipse-based IDE with PDL and CAPSENSE™ middleware) and legacy PSoC™ Creator. Both provide full register-level access, component configurators, and debug via KitProg3 or MiniProg3 programmers compatible with CY8CKIT-149 and CY8CKIT-041-41XX kits.
Is external flash required for firmware updates?
No. The device includes 128 KB on-chip flash with dual-bank capability and bootloader support, enabling secure over-the-air (OTA) or CAN-based firmware updates without external memory. Bootloader configuration is handled via PSoC™ Creator or ModusToolbox™.
