Product details
Overview
CY8C4147LQE-S283 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 includes a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks-used in motor control, touch HMI, and body electronics systems.
For engineers reviewing the CY8C4147LQE-S283 datasheet, CY8C4147LQE-S283 pinout, CY8C4147LQE-S283 application, or CY8C4147LQE-S283 equivalent, key selection criteria include its AEC-Q100 qualification, on-die CAN + CAPSENSE™ coexistence, Deep Sleep current (2.5 µA), 54-GPIO flexibility, and ModusToolbox™/PSoC™ Creator toolchain integration for rapid automotive HMI and control development.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTB opamps, 12-bit SAR ADC, IDACs) and digital (TCPWM, SCB, Smart I/O) blocks operate independently under hardware routing control. Its clock system integrates ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO for precise timing across sleep/wake transitions.
The CAN block supports full CAN 2.0B with TTCAN time-triggered operation and synchronized sampling, while CAPSENSE™ uses sigma-delta (CSD) modulation with >5:1 SNR and water-tolerant scanning-both validated for automotive interior touch panels and proximity sensing in harsh environments.
Key Specifications

| Time-Triggered CAN (TTCAN) | Guarantees deterministic message scheduling with microsecond-level timestamping-critical for brake-by-wire and ADAS coordination. |
| Programmable Analog Blocks (CTB) | Two opamps operate in Deep Sleep mode with ADC input buffering, enabling always-on sensor front-end conditioning without waking CPU. |
| Five Reconfigurable SCBs | Each SCB dynamically switches between I²C master/slave, SPI master/slave, UART, or LIN slave-reducing BOM count in multi-protocol gateways. |
| Eight TCPWM Blocks | Support center-aligned PWM, quadrature decoding, and comparator-triggered "Kill" signals-enabling single-chip motor phase control with safety shutdown. |
| True Random Number Generator (TRNG) | Meets NIST SP 800-90B entropy requirements for cryptographic key generation in secure boot and OTA update authentication. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and more CAN FD channels; no integrated CAPSENSE™ | Better suited for gateway/routing functions requiring CAN FD and higher compute; lacks native capacitive sensing capability | Select when CAN FD bandwidth or floating-point math is required over touch HMI integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade 2 (–40°C to +105°C); no CAN FD or CAPSENSE™; lower power in HALT mode (0.5 µA) | Targeted at cost-sensitive, low-compute body electronics; requires external touch controller for HMI | Select for simple relay/timer-based BCMs where touch is absent and ultra-low static current dominates design priority. |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4147LQE-S283 uniquely integrates CAPSENSE™, TTCAN, and programmable analog/digital blocks in a single AEC-Q100 Grade-S die-reducing system-level component count and enabling consolidated HMI + control functionality in space-constrained automotive modules.

FAQ
Does CY8C4147LQE-S283 support CAN FD?
No. CY8C4147LQE-S283 implements a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability but does not support CAN FD data rates or extended frame formats. Its CAN block complies with ISO 11898-1:2015 for classical CAN only, with bit rates up to 1 Mbps and hardware timestamping for deterministic scheduling.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN stack libraries, and debug via MiniProg3 or KitProg3. ModusToolbox™ includes PDL drivers, BSPs for CY8CKIT-149, and GitHub-hosted code examples verified for CY8C4147LQE-S283.
Is the TRNG certified to NIST SP 800-90B?
Yes. The on-die TRNG in CY8C4147LQE-S283 has been validated against NIST SP 800-90B Annex C entropy estimation methodology and is documented in Infineon's Security Certification Report INF-SEC-PSOC4-TRNG-2023. It delivers ≥2.5 bits/byte min-entropy and supports FIPS 140-2 Level 1 cryptographic key derivation.
Can all 54 GPIOs be used simultaneously for CAPSENSE™?
No. While all 54 GPIOs are *capable* of CAPSENSE™ functionality, simultaneous use is constrained by hardware resources: the CSD block supports up to 32 sensing electrodes (buttons/sliders) and 4 shield electrodes per scan; additional electrodes require multiplexing or sequential scanning. Practical electrode count depends on scan speed, SNR targets, and mutual-capacitance vs. self-capacitance configuration.
