Product details
Overview
CY8C4147AZE-S275T 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 SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), CAN 2.0B with TTCAN support, and eight TCPWM modules-used in automotive body control modules requiring robust touch interfaces and real-time motor timing.
For engineers reviewing the CY8C4147AZE-S275T datasheet, CY8C4147AZE-S275T pinout, CY8C4147AZE-S275T application, or CY8C4147AZE-S275T equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, 54 GPIO with programmable drive modes, Deep Sleep current of 2.5 µA, integrated TRNG for secure boot, and hardware-accelerated CSD engine delivering >5:1 SNR in wet environments.
Technical Context
This device implements a mixed-signal SoC architecture where analog and digital resources are routed via a programmable interconnect matrix. The CAPSENSE™ subsystem uses a dedicated capacitance-sigma-delta (CSD) block with hardware-based SmartSense tuning, while the CAN 2.0B controller supports time-triggered operation with configurable message buffers and error counters.
The clock system integrates four independent sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-enabling precise timing for TCPWM quadrature decoding, LIN slave emulation, and low-power wake-up events without external components.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147AZE-S275T?
The CPU operates at up to 48 MHz, derived from the internal main oscillator (IMO) or external crystal oscillator (ECO) via a programmable PLL. This frequency is guaranteed across the full Grade-S temperature range (–40°C to +105°C) and supply voltage (1.71 V to 5.5 V), enabling deterministic real-time task scheduling in automotive applications.
Does CY8C4147AZE-S275T support hardware-based capacitive touch sensing without external components?
Yes-it integrates a dedicated capacitance-sigma-delta (CSD) block with on-chip IDACs, sequencer, and SmartSense auto-tuning logic. No external RC networks or calibration firmware are required; touch buttons can be implemented using only PCB traces and a ground plane, meeting IEC 61000-4-6 immunity requirements.
Can the CAN peripheral operate in time-triggered mode (TTCAN)?
Yes-the CAN 2.0B block supports TTCAN functionality including time-triggered transmission scheduling, time synchronization via SYNC messages, and deterministic message timing with configurable time windows. This is validated per ISO 11898-1:2015 Annex D and used in body domain controllers for synchronized window lift or mirror fold sequences.
What debug and programming interfaces are supported?
The device supports SWD (Serial Wire Debug) via dedicated debug pins (SWDIO/SWCLK) and is compatible with Infineon's MiniProg3, KitProg3, and industry-standard Arm® debug probes. Flash programming and real-time debugging are fully supported in ModusToolbox™ and PSoC™ Creator IDEs, including memory dump, breakpoint, and trace capabilities.
