Product details
Overview
CY8C4147LQA-S293 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 >5:1 SNR. It includes five reconfigurable SCBs (I²C/SPI/UART/LIN), a CAN 2.0B block with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and body electronics.
For engineers reviewing the CY8C4147LQA-S293 datasheet, CY8C4147LQA-S293 pinout, CY8C4147LQA-S293 application, or CY8C4147LQA-S293 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and 54 GPIO with programmable drive strength and slew rate.
Technical Context
This device implements a mixed-signal SoC architecture where analog and digital resources-including two continuous-time opamps, a 12-bit 1-Msps SAR ADC, dual low-power comparators, and two IDACs-are fully reconfigurable via hardware routing. Its programmable Smart I/O blocks enable Boolean logic directly at the GPIO level without CPU intervention.
The CAN block supports time-triggered communication with deterministic latency and synchronized sampling across multiple nodes, while the TCPWM blocks provide comparator-triggered kill signals for functional safety in motor drive applications. Clocking is managed by a 4–33 MHz ECO, PLL, WCO, and ±2% IMO.

FAQ
Does CY8C4147LQA-S293 support CAN FD?
No. CY8C4147LQA-S293 integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability but does not support CAN FD data rates or frame formats. It complies 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 existing CAN TX/RX pins.
What development tools are officially supported for CY8C4147LQA-S293?
Infineon officially supports ModusToolbox™ (v3.x+) and PSoC™ Creator (v4.4) for firmware development. Hardware debugging uses KitProg3 or MiniProg3 programmers. The CY8CKIT-149 prototyping kit provides direct socket support for CY8C4147LQA-S293 in 48-pin QFN format, including onboard CAN transceiver and CAPSENSE™ slider.
Is the TRNG in CY8C4147LQA-S293 certified to any cryptographic standards?
The TRNG meets NIST SP 800-90B entropy requirements and is validated for use in Infineon's Secure Boot implementation. It is not FIPS 140-3 or Common Criteria certified as a standalone module, but its output feeds into the device's hardware AES engine for key derivation in secure firmware update and authentication flows.
Can all 54 GPIO pins be used simultaneously as CAPSENSE™ sensors?
No. While all GPIO pins are CAPSENSE™-capable, simultaneous use is constrained by shared analog routing resources and CSD block limitations. Maximum supported sensors depend on scan method: up to 32 self-capacitance or 16 mutual-capacitance sensors per CSD block. Dual CSD instances (if present in variant) may increase total count, but CY8C4147LQA-S293 implements one CSD block.
