Product details
Overview
CY8C4147LQE-S443 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 SmartSense auto-tuning. It integrates programmable analog (2 opamps, 12-bit 1-Msps SAR ADC, 2 IDACs), digital logic (TCPWM, SCB, CAN 2.0B), and supports touch-enabled HMI in automotive body control modules.
For engineers reviewing the CY8C4147LQE-S443 datasheet, CY8C4147LQE-S443 pinout, CY8C4147LQE-S443 application, or CY8C4147LQE-S443 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR > 5:1 with water tolerance, CAN 2.0B + TTCAN support, Deep Sleep current of 2.5 µA, and reconfigurable SCB blocks for I²C/SPI/UART/LIN.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (CTB, SAR ADC, IDACs) and digital blocks (TCPWM, SCB, CAN) operate independently under hardware routing control. Its clock system includes ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO - enabling precise timing for motor control and communication.
Capacitive sensing uses 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 CAN (TTCAN) with dedicated message RAM and error counters compliant with ISO 11898-1:2015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic execution for automotive control loops. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - sufficient for OTA-capable firmware with CAPSENSE™ and CAN stack. |
| Analog Peripherals | 2 opamps (Deep Sleep capable), 12-bit 1-Msps SAR ADC, 2 IDACs - supports sensor signal conditioning and self-capacitance measurement. |
| Digital Peripherals | 5 SCBs (I²C/SPI/UART/LIN), 8 TCPWM blocks, CAN 2.0B + TTCAN - enables multi-protocol gateway and motor control with kill-signal triggering. |
| Power & Temp | 1.71–5.5 V supply, Deep Sleep current = 2.5 µA, Grade-S temp range (–40°C to +105°C) - meets automotive interior module requirements. |
| GPIO & Sensing | Up to 54 programmable GPIOs, all CAPSENSE™-capable, CSD SNR > 5:1 with water tolerance - enables scalable touch HMI without external ICs. |
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 |
|---|---|---|
| VDD | Core & I/O power supply | 1.71–5.5 V input; decoupling required per datasheet Section 10.2 for stable Deep Sleep and analog operation. |
| VSS | Ground reference | Common return path for analog/digital domains; separate analog/digital ground routing recommended. |
| P0[0]–P0[7] | Programmable GPIO bank | Support CAPSENSE™, analog input/output, SCB, TCPWM; drive strength/slew rate configurable per pin. |
| XTAL_IN / XTAL_OUT | External crystal oscillator interface | Connects to 4–33 MHz ECO; essential for CAN timing accuracy and USB-free clock calibration. |
| CAN_TX / CAN_RX | Dedicated CAN physical layer interface | Direct connection to CAN transceiver; supports dominant/recessive bit timing per ISO 11898-1. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual threshold tuning and maintains SNR > 5:1 across temperature/humidity. |
| Reconfigurable SCBs | Five independent serial blocks dynamically assignable as I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count in multi-interface nodes. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed latency and synchronized message transmission - critical for distributed chassis control. |
| Deep Sleep with active analog | 2.5 µA system current while opamps and comparators remain operational - enables always-on capacitive wake-up in door handle or seat sensors. |
Applications
| Automotive Door Handle Touch Interface | Body Control Module (BCM) Gateway |
|---|---|

IC Role / Device Role / Timing Role: CAPSENSE™ front-end with LCD segment drive capability and PWM-controlled LED backlight. Use Value: Integrates touch, display, and lighting control - reduces component count from 4 ICs to one PSoC™. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S433 | Same PSoC™ 4100S Plus family, but 40-pin QFN, 64 KB flash, no CAN block, Grade-A (–40°C to +85°C). | Limited to non-CAN interior modules (e.g., ambient light sensor, basic touch panel) without automotive network integration. | Select when CAN is unnecessary and cost-sensitive packaging (40-pin QFN) is preferred. |
| SPC560B50L3 | STMicroelectronics 32-bit Power Architecture MCU, 64 MHz, 512 KB flash, ASIL-B certified, CAN FD, no integrated CAPSENSE™. | Requires external touch controller and analog signal chain; suited for high-integrity powertrain or chassis control. | Select when ASIL-B certification and CAN FD bandwidth are mandatory, and touch is handled separately. |
Compared with CY8C4147AZI-S433, this part adds CAN 2.0B/TTCAN and Grade-S temperature rating for body network nodes; compared with SPC560B50L3, it trades ASIL-B certification for integrated CAPSENSE™ and lower system-level BOM cost in HMI applications.

FAQ
Does CY8C4147LQE-S443 support CAN FD?
No. This device implements CAN 2.0B with time-triggered extensions (TTCAN) per ISO 11898-1:2015, but does not support CAN FD data rates or flexible data-length frames. CAN FD requires dedicated IP blocks found in later-generation Infineon AURIX™ or Traveo™ II devices.
What development tools are officially supported for firmware and CAPSENSE™ tuning?
Infineon officially supports ModusToolbox™ (v3.1+) for firmware development with PDL and CAPSENSE™ middleware, and PSoC™ Creator v4.4 for schematic-based design. Both provide SmartSense auto-tuning configuration, real-time CAPSENSE™ tuning GUI, and debug via MiniProg3 or KitProg3.
Is external flash required for OTA firmware updates?
No. The 128 KB on-chip flash supports dual-bank operation: one bank runs active firmware while the other receives and validates OTA updates. Bootloader implementation is provided in the PDL and validated in AN80717 for automotive use cases.
How is AEC-Q100 Grade-S qualification verified for this part number?
CY8C4147LQE-S443 is qualified per AEC-Q100 Rev-G, including stress tests for temperature cycling (–40°C to +125°C), HTOL (1000 hrs at 125°C), ESD (HBM ±2 kV), and latch-up (±200 mA). Full test reports are available under NDA from Infineon's Automotive Quality portal.
