Product details
Overview
CY8C4147LQS-S293T 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 >5:1 SNR. It includes five reconfigurable serial communication blocks (SCB), eight 16-bit TCPWM units, CAN 2.0B with TTCAN support, and operates from 1.71 V to 5.5 V. Used in automotive body control modules requiring robust touch HMI and real-time motor timing.
For engineers reviewing the CY8C4147LQS-S293T datasheet, CY8C4147LQS-S293T pinout, CY8C4147LQS-S293T application, or CY8C4147LQS-S293T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins 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 (CTB opamps, SAR ADC, IDACs) and digital logic (Smart I/O, TCPWM, SCB) operate independently under hardware routing control. Its clock system integrates ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO for precise timing across sleep/wake transitions.
Capacitive sensing uses a dedicated CSD block with sigma-delta modulation and hardware-accelerated SmartSense tuning-enabling water-tolerant touch interfaces without host CPU intervention. The CAN block supports time-triggered operation with configurable message objects 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 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 complex automotive firmware with fast code execution and data buffering. |
| Operating Voltage | 1.71 V to 5.5 V - allows direct interface with 3.3 V and 5 V automotive subsystems without level-shifting. |
| Deep Sleep Current | 2.5 µA digital system current - sustains low-power wake-on-touch or CAN bus activity in battery-sensitive applications. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - delivers reliable touch detection under condensation, glove use, or EMI-rich vehicle cabins. |
| CAN Interface | CAN 2.0B with TTCAN support - enables synchronized messaging for distributed chassis control and diagnostics. |
| GPIO Count | 54 programmable pins - all support CAPSENSE™, analog input, or digital I/O with configurable drive modes and slew rates. |
Pinout & Package
Package: 64-pin QFN (9 mm × 9 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Independent 1.71–5.5 V supply rails per port group - enables mixed-voltage interfacing (e.g., 3.3 V MCU core + 5 V sensor I/O). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | Each pin supports CAPSENSE™, analog input/output, digital logic, or SCB/CAN functions - routed automatically via PSoC™ Creator. |

| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Direct connection to external CAN PHY - supports 1 Mbps operation and TTCAN timestamping via internal synchronization. |
| VREF / VSSA | Analog reference and ground | Separate analog supply/ground pins reduce noise coupling into SAR ADC and opamp circuits - critical for <1 LSB INL performance. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware SmartSense tuning | Automatic CAPSENSE™ baseline and sensitivity calibration at runtime - eliminates manual firmware compensation for temperature/humidity drift. |
| Reconfigurable SCBs | Five independent serial blocks each configurable as I²C, SPI, UART, or LIN slave - reduces BOM count by consolidating protocol interfaces into one silicon resource. |
| Deep Sleep analog retention | Opamps, comparators, and CSD block remain active during 2.5 µA Deep Sleep - enables always-on touch wake-up and CAN bus monitoring without full wake. |
| TCPWM kill-input triggering | Comparator outputs directly assert hardware kill signals to TCPWM - ensures sub-microsecond motor fault shutdown for functional safety compliance. |
| True Random Number Generator | On-die TRNG certified per NIST SP 800-90B - provides entropy source for secure boot key generation and cryptographic session keys. |

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 S32K144W | ARM Cortex-M4F core, 112 MHz; no integrated CAPSENSE™; requires external touch controller. | Better floating-point math for motor FOC; lacks on-die touch sensing - adds BOM cost and layout complexity. | Select when advanced motor control algorithms dominate over HMI integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; built-in touch I/O but no sigma-delta CSD; no CAN FD or TTCAN. | Lower cost for basic body electronics; limited SNR (<3:1) and no time-triggered CAN - insufficient for synchronized chassis networks. | Select only for non-safety-critical, cost-sensitive interior switches without water tolerance needs. |
Compared with S32K144W and RL78/F14, CY8C4147LQS-S293T uniquely combines AEC-Q100 Grade-S qualification, hardware-accelerated CAPSENSE™, TTCAN, and Deep Sleep analog retention - making it optimal for integrated automotive HMI + control nodes where BOM consolidation and environmental robustness are primary design drivers.

FAQ
Does CY8C4147LQS-S293T support CAN FD?
No. This device implements CAN 2.0B with time-triggered extension (TTCAN) per ISO 11898-1, but does not support CAN FD's higher data rates or flexible data-length frames. It is intended for classic automotive chassis and body networks where TTCAN synchronization suffices, not for high-bandwidth ADAS backbones.
What development tools are officially supported?
Infineon officially supports ModusToolbox™ (Eclipse-based, cross-platform) and legacy PSoC™ Creator (Windows-only). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, TCPWM waveform visualization, and debug via MiniProg3 or KitProg3. Third-party IDEs like Keil MDK and IAR Embedded Workbench are supported via PDL libraries.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The SAR ADC has a single conversion engine with a channel sequencer supporting up to 32 inputs, but no true simultaneous sampling across multiple channels. For multi-channel phase-aligned acquisition, external analog multiplexing or external ADCs with parallel output are required.
How is AEC-Q100 Grade-S qualification verified?
Grade-S qualification was validated per AEC-Q100 Rev-H stress test plan, including HTOL (1000 hrs at 125°C junction), TC (1000 cycles -40°C to +125°C), ESD (HBM ±2 kV), and AC/DC parametric testing across –40°C to +105°C ambient. Full qualification reports are available under NDA from Infineon's automotive support portal.
