Product details
Overview
CY8C4147AZE-S245T 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 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.
For engineers reviewing the CY8C4147AZE-S245T datasheet, CY8C4147AZE-S245T pinout, CY8C4147AZE-S245T application, or CY8C4147AZE-S245T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAN 2.0B with time-triggered capability, Deep Sleep current of 2.5 µA, 54 GPIO with programmable drive modes, and hardware-accelerated CAPSENSE™ with SmartSense auto-tuning.
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 firmware. The programmable Smart I/O block enables Boolean logic on GPIOs without CPU intervention.
The clock system integrates multiple sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-with PLL-based 48-MHz core clock generation. The CAN block supports TTCAN for deterministic timing-critical automotive networks, and TCPWM blocks provide comparator-triggered kill signals for functional safety in motor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and FlexCAN FD-but lacks integrated CAPSENSE™ and programmable analog blocks. | Better suited for gateway or ADAS domain controllers requiring CAN FD and higher compute throughput; not optimized for capacitive HMI. | Select when CAN FD bandwidth or floating-point math acceleration is required; avoid if touch sensing integration and analog configurability are primary needs. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); includes on-chip LCD driver and 10-bit ADC-but no CAN or CAPSENSE™ hardware accelerator. | Targeted at cost-sensitive instrument clusters and simple body control units without advanced HMI or networked diagnostics. | Choose for legacy 16-bit migration or ultra-low-cost entry-level modules; not viable for CAN-based EPS or touch-enabled door modules. |
Compared with S32K144W and RL78/F14, CY8C4147AZE-S245T uniquely combines AEC-Q100 Grade-S operation, hardware CAPSENSE™, TTCAN, and reconfigurable analog/digital blocks in a single die-making it optimal for integrated automotive HMI and distributed control nodes where mixed-signal flexibility and functional safety coexist.

FAQ
Does CY8C4147AZE-S245T support CAN FD?
No. This device integrates a CAN 2.0B controller with time-triggered capability (TTCAN), but does not support CAN FD data rates or extended frame formats. For CAN FD, consider Infineon's AURIX™ TC3xx family or NXP S32K3xx devices.
What development tools are officially supported for this part?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator v4.4 for firmware development, along with CY8CKIT-149 prototyping kit and MiniProg3 programmer/debugger. Both IDEs provide full register-level access, CAPSENSE™ Tuner, and TCPWM configuration GUIs.
Is the TRNG certified to NIST SP 800-90B?
Yes. The on-chip TRNG meets NIST SP 800-90B entropy requirements and is validated for use in cryptographic key generation per Infineon's Common Criteria certification report (CC EAL5+ for PSoC™ 4100S Plus).
Can all 54 GPIO pins be used simultaneously as CAPSENSE™ inputs?
No. While all GPIOs are CAPSENSE™-capable, the CSD block supports up to 32 sensing channels per design. Simultaneous use of all 54 pins requires multiplexing or segmentation-verified in AN85951 and CAPSENSE™ Component Datasheet Rev.*E.
