Product details
Overview
CY8C4147LQA-S453 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 delivers programmable analog (2 opamps, 12-bit 1-Msps SAR ADC, 2 IDACs), digital logic (8 TCPWM, 5 SCBs), CAN 2.0B with TTCAN support, and LCD segment drive - deployed in automotive body control modules requiring robust touch interfaces and real-time motor timing.
For engineers reviewing the CY8C4147LQA-S453 datasheet, CY8C4147LQA-S453 pinout, CY8C4147LQA-S453 application, or CY8C4147LQA-S453 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN compliance, Deep Sleep current of 2.5 µA, and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN in runtime.
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, LPC) and digital blocks (TCPWM, SCB, CAN) operate concurrently under hardware routing control. Its clock system integrates ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO for deterministic timing across sleep/wake transitions.
CAPSENSE™ uses capacitance-sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, enabling self-calibrating touch buttons/sliders in harsh environments. The CAN block supports time-triggered operation 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 - enables deterministic real-time control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM - supports secure bootloader storage, firmware updates, and real-time data buffering without external memory. |
| ADC | 12-bit SAR ADC, 1 Msps, differential/single-ended, channel sequencer with signal averaging - provides high-resolution sensor acquisition for temperature, pressure, or position feedback. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with SNR >5:1 and water tolerance - enables reliable touch interface operation in humid or wet automotive cabin environments. |
| CAN Interface | CAN 2.0B + TTCAN support - delivers time-synchronized messaging for distributed chassis control networks meeting AUTOSAR timing constraints. |
| 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-touch or CAN activity. |
| GPIO Count | Up to 54 programmable pins in 48-pin QFN package - supports mixed-signal routing with configurable drive strength, slew rate, and CAPSENSE™/analog/digital assignment per pin. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| 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 logic + 5 V analog sensors). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | Each pin supports CAPSENSE™, analog input/output, digital logic, or SCB function - configured via PSoC™ Creator or ModusToolbox™. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Hardwired to internal CAN controller; requires external CAN transceiver (e.g., TJA1042) for bus physical layer compliance. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for precise timing; used for PLL reference or high-accuracy UART baud generation. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC operation 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 threshold tuning and maintains stable button response across temperature/humidity drift. |
| Reconfigurable SCBs | Five serial communication blocks dynamically switch between I²C master/slave, SPI master/slave, UART, or LIN slave - reducing BOM count and PCB footprint. |
| Deep Sleep Analog Operation | Opamps and comparators remain active in Deep Sleep mode at 2.5 µA system current - enables always-on touch wake-up or analog monitoring without full MCU wake. |
| TTCAN Support | Time-triggered CAN scheduling with guaranteed message latency and synchronization to global time base - critical for safety-critical chassis control loops. |
| True Random Number Generator | TRNG compliant with NIST SP 800-90B - provides entropy source for cryptographic key generation in secure boot or OTA update authentication. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S433 | Same PSoC™ 4100S Plus core but in 48-pin TQFP package; no CAN block; Grade-A (–40°C to +85°C) | Lacks CAN and TTCAN; limited to non-networked interior modules like ambient lighting or simple switches | Select only if CAN is unnecessary and TQFP assembly is preferred over QFN. |
| SPC560B50L5 | 32-bit Power Architecture e200z0h core; 512 KB flash; includes CAN FD, Ethernet, and ASIL-B safety features | Higher functional safety certification (ISO 26262 ASIL-B); targets gateway or domain controller roles, not touch-peripheral nodes | Choose when system-level safety compliance or CAN FD bandwidth exceeds CY8C4147LQA-S453 capability. |
Compared with CY8C4147AZI-S433 and SPC560B50L5, the CY8C4147LQA-S453 uniquely balances AEC-Q100 Grade-S operation, integrated CAPSENSE™ with water tolerance, and TTCAN in a compact QFN package - making it optimal for cost-sensitive, space-constrained automotive HMI edge nodes.

FAQ
What is the maximum operating temperature for CY8C4147LQA-S453?
The CY8C4147LQA-S453 is qualified to AEC-Q100 Grade-S, with a specified operating junction temperature range of –40°C to +105°C. This rating applies to continuous operation under full peripheral load and 48-MHz CPU execution, validated per stress test conditions in the official Infineon qualification report.
Does CY8C4147LQA-S453 support CAN FD?
No, CY8C4147LQA-S453 implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD data rates or flexible data-length frames. For CAN FD, Infineon recommends the TRAVEO™ T2G or AURIX™ TC3xx families, which include native CAN FD controllers.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes - CAPSENSE™ CSD scanning can run autonomously in Deep Sleep mode using the low-power comparator and IDAC blocks, with results stored in dedicated registers. The CPU remains powered down until a touch event triggers a wakeup interrupt, achieving 2.5 µA total system current during idle.
Is ModusToolbox™ required for development with this device?
No - both ModusToolbox™ and the legacy PSoC™ Creator IDE fully support CY8C4147LQA-S453. ModusToolbox™ offers modern CI/CD integration and GitHub-based libraries, while PSoC™ Creator provides schematic-based design entry and automatic analog/digital routing - choice depends on team workflow preference and project maturity.
