Product details
Overview
CY8C4147AZE-S265T 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 touch-sensing with SmartSense auto-tuning. It delivers programmable analog (2 opamps, 12-bit 1-Msps SAR ADC, 2 IDACs), digital logic (TCPWM, SCB, CAN 2.0B), and GPIO flexibility for embedded control in body electronics and human-machine interface systems.
For engineers reviewing the CY8C4147AZE-S265T datasheet, CY8C4147AZE-S265T pinout, CY8C4147AZE-S265T application, or CY8C4147AZE-S265T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN support, Deep Sleep current of 2.5 µA, and reconfigurable SCBs for I²C/SPI/UART/LIN.
Technical Context
This device implements a mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable analog blocks (CTB, SAR ADC, LPC) and digital peripherals (TCPWM, SCB, CAN) via a flexible interconnect matrix. Its clock system integrates ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO for precise timing across operating modes.
The CAPSENSE™ subsystem uses capacitive sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, enabling robust touch detection without manual calibration. The CAN block supports time-triggered communication (TTCAN) and message filtering, while five SCBs allow runtime reconfiguration between I²C, SPI, UART, and LIN slave protocols.

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 but no integrated CAPSENSE™; requires external touch controller | Better for gateway/communication-heavy nodes; lacks on-chip capacitive sensing capability | Select when CAN FD, Ethernet, or floating-point math is prioritized over integrated HMI sensing |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or CAPSENSE™; lower flash density (512 KB max) | Suitable for cost-sensitive body control units without advanced HMI; limited analog performance | Select for legacy 16-bit migration paths where toolchain continuity outweighs mixed-signal integration needs |
Compared with S32K144W and RL78/F14, CY8C4147AZE-S265T uniquely combines automotive-grade CAPSENSE™, TTCAN, and Deep Sleep analog retention in a single die-enabling compact, low-BOM HMI nodes without compromising functional safety or signal integrity.

FAQ
What is the maximum operating temperature range for CY8C4147AZE-S265T?
CY8C4147AZE-S265T is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per stress test conditions defined in the AEC-Q100 standard and applies to the full 48-pin QFN package variant under specified voltage and load conditions.
Does CY8C4147AZE-S265T support CAN FD?
No. CY8C4147AZE-S265T integrates a CAN 2.0B controller with time-triggered CAN (TTCAN) support but does not implement CAN FD physical layer or protocol extensions. It complies fully with ISO 11898-1:2015 for classical CAN at up to 1 Mbps, with TTCAN scheduling meeting ASAM MCD-2 MC timing constraints.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD sensing remains fully functional in Deep Sleep mode with only 2.5 µA total system current. The analog front-end (CTB, IDACs, CSD modulator) and dedicated low-power clock domain remain active, enabling wake-on-touch with sub-100 ms latency and no firmware intervention required.
Is ModusToolbox™ required for development with this device?
No. While ModusToolbox™ is Infineon's recommended modern IDE with PDL and middleware support, CY8C4147AZE-S265T is fully supported in the legacy PSoC™ Creator IDE (Windows-only), which provides schematic-based design entry, automatic routing, and CAPSENSE™ component configuration. Both environments generate identical binary output.
