Product details
Overview
CY8C4147LQE-S263 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 a CAN 2.0B block with time-triggered support, five reconfigurable serial communication blocks (SCBs), and eight TCPWM modules-enabling use in motor control, body electronics, and touch-enabled cockpit interfaces.
For engineers reviewing the CY8C4147LQE-S263 datasheet, CY8C4147LQE-S263 pinout, CY8C4147LQE-S263 application, or CY8C4147LQE-S263 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-chip CAN 2.0B with TTCAN, Deep Sleep current of 2.5 µA, 12-bit 1-Msps SAR ADC, and programmable analog/digital routing for mixed-signal system integration.
Technical Context
The device implements a tightly coupled MCU subsystem with configurable clock sources including a 4–33 MHz ECO, PLL-based 48-MHz core clock, and low-power ILO/WCO oscillators. Its analog subsystem integrates two opamps with Deep Sleep operation, dual low-power comparators, and a dedicated capacitance-sensing sigma-delta (CSD) block delivering >5:1 SNR and water tolerance.
Digital resources include eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, five SCBs individually configurable as I²C/SPI/UART/LIN, and a dedicated CAN 2.0B controller with TTCAN compliance-enabling deterministic timing for automotive networked control loops.

FAQ
Does CY8C4147LQE-S263 support CAN FD?
No. CY8C4147LQE-S263 integrates a CAN 2.0B controller with time-triggered CAN (TTCAN) capability but does not support CAN FD data rates or extended frame formats. It is compliant with ISO 11898-1:2015 for classical CAN only. For CAN FD, consider Infineon's AURIX™ TC3xx family or external CAN FD transceivers paired with this device's SCB UART mode for bridging.
What development tools are officially supported for CY8C4147LQE-S263?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4) for firmware development. Hardware debugging and programming require MiniProg3 or KitProg3 programmers. The CY8CKIT-149 prototyping kit provides direct socket support for CY8C4147LQE-S263 in 48-pin QFN format, including CAN transceiver and CAPSENSE™ evaluation headers.
Is the TRNG in CY8C4147LQE-S263 certified to NIST SP 800-90A or AIS-31?
The TRNG meets the statistical randomness requirements defined in NIST SP 800-22 and is implemented per Infineon's proprietary entropy source architecture. While not individually certified to NIST SP 800-90A or AIS-31, it is qualified for use in secure boot and key derivation within Infineon's PSoC™ Secure Boot framework, which aligns with ISO/SAE 21434 cybersecurity development practices.
Can all GPIO pins be used simultaneously for CAPSENSE™ and analog functions?
Yes-up to 54 GPIO pins support CAPSENSE™, analog input/output, and digital functions concurrently. However, shared analog resources (e.g., opamp inputs, SAR ADC channels) impose functional limits: only two opamps and one SAR ADC are available, so simultaneous use of all pins for high-speed analog acquisition or concurrent CAPSENSE™ + opamp buffering requires careful resource allocation in PSoC™ Creator or ModusToolbox™ configurators.
