Product details
Overview
CY8C4547AZI-S453 from Infineon is a 32-bit PSoC™ 4500S microcontroller based on the Arm® Cortex®-M0+ CPU, operating at up to 48 MHz with 256 KB flash and 32 KB SRAM. It integrates programmable analog (dual 12-bit 1-Msps SAR ADCs, four opamps), digital logic blocks, CAPSENSE™ capacitive sensing, and five reconfigurable Serial Communication Blocks (SCBs) for I²C/SPI/UART. It targets embedded human-interface and motor-control applications requiring mixed-signal integration and low-power operation down to 2.5 µA in Deep Sleep.
For engineers reviewing the CY8C4547AZI-S453 datasheet, CY8C4547AZI-S453 pinout, CY8C4547AZI-S453 application, or CY8C4547AZI-S453 equivalent, key selection criteria include its 48-pin TQFP package, dual SAR ADC simultaneous sampling capability, Deep Sleep current specification, CAPSENSE™ SNR (>5:1), and hardware-accelerated motor control functions including square root and divide operations.
Technical Context
The device implements a tightly coupled subsystem where the Arm® Cortex®-M0+ core interfaces directly with configurable analog blocks (opamps, comparators, IDACs) and digital peripherals (TCPWM, SCBs, MCA). Its programmable routing fabric enables dynamic signal path assignment without external components.
Capacitive sensing uses a dedicated sigma-delta modulator with SmartSense™ automatic hardware tuning, delivering >5:1 SNR and water-tolerance-critical for consumer touch interfaces. The Motor Control Accelerator (MCA) provides dedicated hardware for Field Oriented Control (FOC) and Power Factor Correction (PFC) computations, offloading the CPU from real-time math-intensive tasks.
Key Specifications

FAQ
Does CY8C4547AZI-S453 support USB connectivity?
No, CY8C4547AZI-S453 does not include a USB PHY or USB controller. It relies on external USB-to-UART bridges or host-side USB conversion for PC connectivity. Its five SCBs support only I²C, SPI, and UART protocols natively-USB functionality requires external silicon or a higher-tier PSoC™ 6 device with integrated USBFS.
What debug interfaces are supported, and is JTAG available?
CY8C4547AZI-S453 supports Arm® Serial Wire Debug (SWD) only-not JTAG. SWD uses two pins (SWDCLK and SWDIO) and is fully compatible with MiniProg4, CMSIS-DAP debuggers, and third-party tools like Segger J-Link. The debug interface is enabled by default and can be disabled in firmware; re-enabling requires full flash erase.
Can the CAPSENSE™ block operate independently of the CPU during Deep Sleep?
Yes, the CAPSENSE™ sigma-delta sensing engine operates autonomously in Deep Sleep mode using the internal ILO clock. It can detect touch events and generate interrupts to wake the CPU, with typical current draw of 2.5 µA for the entire system-including active analog blocks-making it suitable for battery-powered touch interfaces.
Is there hardware encryption support for secure boot or firmware updates?
No, CY8C4547AZI-S453 does not include dedicated cryptographic accelerators (AES, SHA, RSA) or secure boot ROM. Flash protection features (read/write lock bits) provide basic IP protection, but secure firmware authentication and encrypted OTA updates require external secure elements or software-based implementations with performance trade-offs.
