Product details
Overview
CY8C4147AZI-S453T 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 includes five reconfigurable serial communication blocks (SCB), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and operates from 1.71 V to 5.5 V. Used in automotive body control modules requiring robust touch HMI and real-time motor timing.
For engineers reviewing the CY8C4147AZI-S453T datasheet, CY8C4147AZI-S453T pinout, CY8C4147AZI-S453T application, or CY8C4147AZI-S453T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR > 5:1, CAN 2.0B + TTCAN compliance, Deep Sleep current ≤ 2.5 µA, and 54-GPIO flexibility with programmable drive modes.
Technical Context
This device implements a mixed-signal SoC architecture integrating fixed-function peripherals (CAN, SCB, TCPWM) with programmable analog (CTB opamps, SAR ADC, IDACs) and digital (Smart I/O, PLD) resources routed via automatic interconnect fabric. Its clock system combines ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO for precise timing across sleep/wake states.
The CAPSENSE™ subsystem uses capacitive sigma-delta (CSD) sensing with hardware-accelerated SmartSense tuning and supports water-tolerant HMI designs. The CAN block supports time-triggered operation with dedicated message RAM and error counters compliant with ISO 11898-1:2015.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147AZI-S453T?
The CY8C4147AZI-S453T runs its Arm® Cortex®-M0+ CPU at a maximum frequency of 48 MHz, achieved via internal PLL multiplication of the 4–33 MHz external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and voltage range (1.71 V to 5.5 V).
Does CY8C4147AZI-S453T support CAN FD or only classical CAN 2.0B?
CY8C4147AZI-S453T implements a CAN 2.0B controller compliant with ISO 11898-1:2015 and supports time-triggered CAN (TTCAN), but does not support CAN FD data rates or frame formats. Its CAN block includes dedicated message RAM, transmit/receive buffers, and error counters, optimized for deterministic communication in body domain networks-not high-bandwidth powertrain applications.
How many GPIO pins support CAPSENSE™ functionality, and what is the minimum detectable capacitance change?
All 54 GPIO pins on CY8C4147AZI-S453T can be configured for CAPSENSE™ CSD operation. The subsystem achieves >5:1 signal-to-noise ratio and detects capacitance changes down to 1 fF typical, enabled by hardware-accelerated SmartSense auto-tuning and programmable IDAC current sources. Sensitivity is validated under AEC-Q100 Grade-S conditions including humidity and temperature cycling.
Is ModusToolbox™ software required to develop firmware for this device, or is PSoC™ Creator still supported?
Both ModusToolbox™ and PSoC™ Creator are officially supported for CY8C4147AZI-S453T. PSoC™ Creator remains fully functional for schematic-based design and legacy projects, while ModusToolbox™ is Infineon's strategic IDE-neutral platform offering GitHub-hosted BSPs, PDL, CAPSENSE™ middleware, and Eclipse-based project creation. Migration paths and interoperability between both tools are documented in AN79953 and the PSoC™ 4100S Plus TRM.
