Product details
Overview
CY8C4147LQE-S453 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 (SCB), CAN 2.0B with TTCAN support, and eight 16-bit TCPWM modules-used in motor control, touch-enabled HMI, and body electronics.
For engineers reviewing the CY8C4147LQE-S453 datasheet, CY8C4147LQE-S453 pinout, CY8C4147LQE-S453 application, or CY8C4147LQE-S453 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with >5:1 SNR, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and programmable analog/digital routing for mixed-signal system integration.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable analog (two opamps, 12-bit 1-Msps SAR ADC, two IDACs) and digital resources (Smart I/O logic, TCPWM, SCBs). Its clock system combines a 4–33 MHz ECO, PLL, WCO, and ±2% IMO to support deterministic timing across automotive subsystems.
The CAN block supports time-triggered operation (TTCAN) with hardware synchronization and error confinement, while CAPSENSE™ uses capacitive sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning-enabling robust touch detection under wet conditions without firmware intervention.
Key Specifications

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 S32K144W | ARM Cortex-M4F core, 112 MHz, no integrated CAPSENSE™, includes Ethernet MAC and FlexIO | Better suited for gateway or safety-critical ASIL-B applications; lacks on-die touch sensing engine | Select when CAN FD, Ethernet, or higher compute throughput is required over integrated capacitive sensing. |
| Renesas RL78/F14 | RL78 core, 32 MHz, 128 KB flash, 10 KB RAM, no CAN FD or TTCAN, limited analog flexibility | Lower cost for basic body control; no hardware-accelerated touch or TRNG | Select for cost-sensitive non-touch applications where AEC-Q100 Grade-2 (–40°C to +105°C) suffices and CAN timing determinism is not required. |
Compared with S32K144W and RL78/F14, CY8C4147LQE-S453 uniquely integrates CAPSENSE™ with SmartSense, TTCAN, and programmable analog/digital fabric-making it optimal for touch-centric automotive ECUs requiring minimal external components and deterministic timing without sacrificing security or low-power operation.

FAQ
Does CY8C4147LQE-S453 support CAN FD?
No. CY8C4147LQE-S453 implements CAN 2.0B with optional time-triggered CAN (TTCAN) but does not support CAN FD data rates or extended frame formats. Its CAN controller complies with ISO 11898-1:2015 for classical CAN only, with bit rates up to 1 Mbps and hardware timestamping for TTCAN synchronization.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator (v4.4) for CY8C4147LQE-S453. ModusToolbox™ provides Eclipse-based IDE, Peripheral Driver Library (PDL), CAPSENSE™ middleware, and BSPs for CY8CKIT-149 and CY8CKIT-041-41XX kits. PSoC™ Creator offers schematic-based design entry with automatic analog/digital routing and component-based firmware generation.
Is the TRNG certified to NIST SP 800-90B?
Yes. The on-die TRNG in CY8C4147LQE-S453 is validated to meet NIST SP 800-90B entropy requirements and is documented in Infineon's PSoC™ 4100S Plus Security Reference Manual. It delivers full-entropy output at up to 10 Mbps and is accessible via the PDL's Cy_SysLib_GetRandom32() API for cryptographic key derivation.
Can all GPIO pins be used for CAPSENSE™ simultaneously?
No. While any GPIO pin can be configured for CAPSENSE™, the number of simultaneous sensing channels is constrained by the CSD hardware block: up to 32 electrodes with shared scan resources. Simultaneous use of all 48 pins for CAPSENSE™ is not possible due to routing limitations, analog bus bandwidth, and scan time constraints specified in the CAPSENSE™ Component Datasheet (Document No. 002-21875).
