Product details
Overview
CY8C4147AZE-S465T 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 systems.
For engineers reviewing the CY8C4147AZE-S465T datasheet, CY8C4147AZE-S465T pinout, CY8C4147AZE-S465T application, or CY8C4147AZE-S465T 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 CAPSENSE™ SmartSense auto-tuning for wet-environment touch interfaces.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital resources (TCPWM, SCB, CAN, Smart I/O) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.
Its clock system integrates multiple sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-with PLL enabling precise 48-MHz CPU operation. The CAN block supports TTCAN for deterministic timing-critical automotive networks, and CAPSENSE™ uses sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max-enables real-time deterministic execution for automotive control loops. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM-supports complex firmware with CAPSENSE™ and CAN stack. |

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 @ 112 MHz; includes Ethernet MAC and FlexIO; no integrated CAPSENSE™; larger 100-pin LQFP package. | Better suited for high-speed gateway or ADAS sensor fusion; lacks native capacitive touch IP-requires external touch controller. | Select when Ethernet connectivity or floating-point math performance is mandatory; avoid if CAPSENSE™ integration and compact QFN are design priorities. |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz; 512 KB flash; CAN 2.0B only (no TTCAN); no TRNG or hardware CAPSENSE™. | Targeted at cost-sensitive body electronics; limited analog capability-requires external ADC/opamp for sensor conditioning. | Choose for simple relay control or LIN-only modules where AEC-Q100 Grade-S and CAN are sufficient but advanced mixed-signal features are unnecessary. |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4147AZE-S465T uniquely combines AEC-Q100 Grade-S qualification, on-die TTCAN, CAPSENSE™ with SmartSense, and Deep Sleep analog operation in a 48-pin QFN-making it optimal for space-constrained, touch-enabled automotive ECUs requiring deterministic timing and low-power always-on sensing.

FAQ
Does CY8C4147AZE-S465T support CAN FD?
No. This device implements CAN 2.0B with optional time-triggered CAN (TTCAN) functionality only. It does not support CAN FD data rates or extended frame formats. For CAN FD requirements, consider Infineon's AURIX™ TC3xx family or evaluate external CAN FD transceivers paired with protocol software stacks.
What development tools are officially supported for this part?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator (v4.4) IDEs. Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN stack libraries, and debug support via KitProg3 or MiniProg4. Third-party tools like Keil MDK and IAR Embedded Workbench are compatible via Arm® CMSIS-Pack integration.
Is the TRNG certified to NIST SP 800-90B?
Yes. The on-chip TRNG meets NIST SP 800-90B entropy requirements and is validated per Infineon's Common Criteria certification (EAL5+ for PSoC™ 4100S Plus). It delivers certified random bits at up to 10 Mbps and is accessible via PDL APIs for cryptographic key derivation and nonce generation.
Can all 54 GPIO pins be used simultaneously for CAPSENSE™?
No. While all GPIOs are CAPSENSE™-capable, practical implementation is limited by mutual capacitance coupling and scan time constraints. The datasheet specifies up to 32 self-capacitance or 16 mutual-capacitance sensors per device, depending on resolution and SNR targets. Layout and firmware tuning determine actual usable count.
