Product details
Overview
CY8C4147LQA-S273 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus programmable system-on-chip 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 dual opamps, 12-bit 1-Msps SAR ADC, CAN 2.0B with TTCAN support, and five reconfigurable serial communication blocks (SCBs), enabling embedded control in automotive body electronics and infotainment interfaces.
For engineers reviewing the CY8C4147LQA-S273 datasheet, CY8C4147LQA-S273 pinout, CY8C4147LQA-S273 application, or CY8C4147LQA-S273 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, Deep Sleep current of 2.5 µA, 54 GPIO with full CAPSENSE™/analog/digital reconfiguration, and hardware-accelerated sigma-delta capacitive sensing with >5:1 SNR.
Technical Context
This 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 logic (TCPWM, SCB, CAN) operate concurrently under hardware routing control. Its clock system includes ECO (4–33 MHz), PLL (48 MHz output), WCO (32 kHz), IMO (±2%), and ILO - all supporting dynamic low-power mode transitions.
The CAPSENSE™ subsystem uses capacitance-sigma-delta (CSD) modulation with hardware-based SmartSense tuning, delivering water-tolerant touch performance without host CPU intervention. The CAN block supports time-triggered operation (TTCAN) with dedicated message RAM and error counters compliant with ISO 11898-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM - supports complex automotive firmware with fast code execution and data buffering. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with signal averaging - enables high-fidelity sensor acquisition in motor control or battery monitoring. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with >5:1 SNR and automatic SmartSense tuning - delivers robust touch detection under moisture or EMI without firmware calibration. |
| CAN Interface | CAN 2.0B with TTCAN support, 32-message object RAM - meets automotive network timing determinism and fault confinement requirements. |
| Power Range | 1.71 V to 5.5 V supply; Deep Sleep current = 2.5 µA - allows direct connection to automotive battery rails with ultra-low standby power. |
| GPIO Count | 54 programmable pins across QFN/TQFP packages; any pin supports CAPSENSE™, analog, or digital functions - eliminates fixed-peripheral pin constraints in layout. |
Pinout & Package
CY8C4147LQA-S273 is packaged in a 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch) with wettable flank terminations for automotive-grade solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Four independent 1.71–5.5 V supplies enable mixed-voltage interface (e.g., 3.3 V MCU core + 5 V analog sensors). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | All 54 pins support configurable drive modes (open-drain, push-pull), slew rate, and CAPSENSE™/analog/digital assignment at runtime. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for precise timing; required for CAN bit timing accuracy and clock redundancy. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Hardwired to internal CAN controller; isolated from GPIO mux to guarantee signal integrity and EMC compliance. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC operation and low-power wake-up events during Deep Sleep without waking CPU. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CAPSENSE™ CSD engine | Offloads touch scanning and noise rejection to dedicated analog/digital hardware, freeing CPU cycles for safety-critical tasks. |
| SmartSense auto-tuning | Adjusts sensor parameters (IDAC, resolution, scan time) in real time based on environmental drift - eliminates factory calibration per unit. |
| Reconfigurable SCBs | Five serial blocks can be independently assigned as I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count vs. discrete protocol ICs. |
| TTCAN support | Time-triggered scheduling with guaranteed message transmission windows - satisfies ASAM MCD-2 MC and AUTOSAR COM timing requirements. |
| Deep Sleep with active analog | Opamps, comparators, and CAPSENSE™ remain operational at 2.5 µA system current - enables always-on touch wake-up in door handle or center console applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, 112 MHz; no integrated CAPSENSE™; requires external touch controller for capacitive sensing. | Better floating-point performance for motor control math; lacks hardware-accelerated touch, increasing BOM and firmware complexity for HMI. | Select when high-precision motor control dominates over touch interface needs. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; integrated touch I/O but no sigma-delta CSD; lower SNR (<3:1) and no SmartSense. | Suitable for cost-sensitive non-safety touch applications; lacks TTCAN and fails ASIL-B diagnostic coverage for EPB. | Select only for non-safety-critical interior switches with dry-environment operation. |
Compared with NXP S32K144 and Renesas RL78/F14, CY8C4147LQA-S273 uniquely combines AEC-Q100 Grade-S qualification, hardware CAPSENSE™ with SmartSense, TTCAN, and Deep Sleep analog retention - making it optimal for integrated automotive HMI and distributed control nodes where touch reliability and low-power responsiveness are critical.

FAQ
What is the maximum operating temperature grade for CY8C4147LQA-S273?
CY8C4147LQA-S273 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition Tc = +105°C and applies to all functional blocks including CPU, CAPSENSE™, CAN, and analog peripherals - confirmed in Infineon's official qualification report 002-20072 Rev. *S.
Does CY8C4147LQA-S273 support CAN FD?
No, CY8C4147LQA-S273 implements CAN 2.0B only, with TTCAN extensions for time-triggered scheduling. It does not support CAN FD data rates or flexible data-length frames. For CAN FD capability, Infineon's TRAVEO™ T2G or AURIX™ TC3xx families are recommended alternatives.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes - CAPSENSE™ CSD hardware remains fully active in Deep Sleep mode with only 2.5 µA total system current. Electrode scanning, baseline tracking, and SmartSense auto-tuning continue autonomously without CPU involvement, enabling instant wake-up on touch event detection.
Which development tools are officially supported for CY8C4147LQA-S273?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4) for firmware development.
