Product details
Overview
CY8C4147AZE-S265 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 >5:1 SNR. It includes five reconfigurable serial communication blocks (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and body electronics.
For engineers reviewing the CY8C4147AZE-S265 datasheet, CY8C4147AZE-S265 pinout, CY8C4147AZE-S265 application, or CY8C4147AZE-S265 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive modes.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where analog resources-including two opamps, a 12-bit 1-Msps SAR ADC, dual IDACs, and low-power comparators-are directly routable to programmable digital logic and TCPWM peripherals. The CAN block supports time-triggered operation with hardware synchronization to system clocks and configurable message buffers.
The clock system combines a 4–33 MHz ECO, PLL for 48-MHz core generation, 32-kHz WCO, and ±2% IMO, enabling precise timing for CAN bit timing, PWM dead-time insertion, and CAPSENSE™ sigma-delta modulation-all while maintaining Deep Sleep operation with active analog monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control for automotive body modules and sensor fusion. |
| Flash / SRAM | 128 KB flash with Read Accelerator / 16 KB SRAM - supports secure bootloader, OTA updates, and multi-tasking firmware without external memory. |
| CAN Interface | CAN 2.0B with TTCAN support - provides synchronized, deterministic messaging for chassis control and gateway applications. |
| CAPSENSE™ Performance | Sigma-delta CSD with >5:1 SNR and water tolerance - delivers robust touch detection in automotive interior panels under condensation or glove use. |
| Power Modes | Deep Sleep at 2.5 µA with active analog - allows always-on capacitive wake-up and low-power sensor monitoring in battery-constrained ECUs. |

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, 1 MB flash, no integrated CAPSENSE™; requires external touch controller. | Better floating-point performance for motor control math, but higher BOM cost and larger footprint for touch HMI. | Select when advanced motor control algorithms dominate over capacitive interface needs. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, 512 KB flash, AEC-Q100 Grade-2 (–40°C to +105°C), no CAN FD or TTCAN. | Lower cost for simple LIN/CAN nodes, but lacks sigma-delta CAPSENSE™ and Deep Sleep analog retention. | Select for cost-sensitive body electronics where touch is implemented externally or omitted. |
Compared with S32K144W and RL78/F14, CY8C4147AZE-S265 uniquely integrates high-SNR CAPSENSE™, TTCAN, and sub-3 µA Deep Sleep with active analog-making it optimal for compact, touch-enabled automotive ECUs requiring functional safety readiness and low-power always-on capability.

FAQ
Does CY8C4147AZE-S265 support CAN FD?
No. CY8C4147AZE-S265 implements CAN 2.0B with optional time-triggered CAN (TTCAN) functionality, but does not support CAN FD data rates or extended frame formats. Its CAN controller complies with ISO 11898-1:2015 for classical CAN only.
What is the maximum operating frequency of the internal main oscillator (IMO)?
The internal main oscillator (IMO) operates at a factory-trimmed 48 MHz with ±2% accuracy across temperature and voltage. It serves as the default clock source for the CPU and peripherals unless replaced by the PLL-fed ECO or WCO-derived clocks.
Can all 54 GPIO pins be used simultaneously for CAPSENSE™?
No. While all 54 pins are CAPSENSE™-capable, practical implementation is limited by mutual capacitance coupling and scan time. The datasheet specifies up to 32 self-capacitance or 16 mutual-capacitance sensors per device, depending on resolution and SNR requirements.
Is ModusToolbox™ required for development with this device?
No. ModusToolbox™ is recommended for modern projects due to its PDL, middleware, and Eclipse IDE integration, but legacy PSoC™ Creator (Windows-only) remains fully supported and provides schematic-based design entry, automatic routing, and CAPSENSE™ component configuration.
