Product details
Overview
CY8C4147LQA-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 SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks-used in automotive body control modules requiring robust touch interfaces and real-time motor timing.
For engineers reviewing the CY8C4147LQA-S293T datasheet, CY8C4147LQA-S293T pinout, CY8C4147LQA-S293T application, or CY8C4147LQA-S293T equivalent, this device delivers verified automotive-grade mixed-signal integration, deterministic low-latency CAPSENSE™ response (<10 ms full-scan), CAN bus synchronization via hardware-triggered Kill signals, and Deep Sleep operation at 2.5 µA system current with active analog monitoring.
Technical Context
The CY8C4147LQA-S293T implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable digital logic (Smart I/O) and analog blocks (CTB opamps, SAR ADC, IDACs) operate independently under hardware routing control. Its CAN 2.0B block supports time-triggered scheduling with dedicated message RAM and error counters compliant with ISO 11898-1:2015.
Capacitive sensing uses sigma-delta (CSD) modulation with >5:1 SNR and water-tolerant scanning, enabled by on-chip CSD block and automatic SmartSense tuning that adjusts baseline, threshold, and scan parameters without host CPU intervention. Clocking includes PLL-synthesized 48 MHz, 32-kHz WCO for RTC, and ±2% IMO for fast wake-up from Deep Sleep.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz, 1 MB flash, CAN FD, no integrated CAPSENSE™ - requires external touch controller. | Better for high-speed motor control with FPU and CAN FD, but adds BOM cost and layout complexity for touch interfaces. | Select when floating-point math, CAN FD bandwidth (>5 Mbps), or ASIL-D decomposition is required; not drop-in for CAPSENSE™-centric designs. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, 512 KB flash, built-in touch I/O (no SmartSense), no CAN - supports LIN only. | Limited to cost-sensitive LIN-only body nodes without real-time touch or CAN connectivity. | Choose for legacy LIN-based modules where touch is secondary and CAN is unnecessary; lacks automotive-grade CAPSENSE™ SNR and water tolerance. |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4147LQA-S293T uniquely integrates certified automotive touch sensing, TTCAN, and Deep Sleep analog monitoring in a single 48-pin QFN - enabling compact, low-power, ASIL-B-compliant body electronics without external analog or timing components.

FAQ
Is CY8C4147LQA-S293T qualified for automotive use?
Yes. It is AEC-Q100 Grade-S qualified (–40°C to +105°C), with full documentation including stress test reports, failure-in-time (FIT) data, and PPAP-ready manufacturing records. All qualification testing was performed per AEC-Q100 Rev-G standards at Infineon's certified automotive labs.
Does it support CAN FD or only classical CAN?
CY8C4147LQA-S293T supports only classical CAN 2.0B with TTCAN extensions - not CAN FD. Its CAN block implements ISO 11898-1:2015 compliant bit timing, message filtering, and hardware time-triggered scheduling, but lacks the 64-byte payload and variable bit rate capabilities of CAN FD.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD scanning can run autonomously in Deep Sleep using the ILO clock source, with results stored in dedicated registers. The CPU remains powered off while the CSD block performs full-button scans at user-defined intervals, consuming only 2.5 µA total system current.
What development tools are officially supported?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide validated CAPSENSE™ tuning utilities, CAN configuration wizards, TCPWM code generators, and debug support via MiniProg3 or KitProg3 programmers - no third-party toolchain required.
