Product details
Overview
CY8C4547AZQ-S473 from Infineon is a PSoC™ 4500S-series 32-bit Arm® Cortex®-M0+ microcontroller with 256 KB flash, 32 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It features dual 12-bit 1-Msps SAR ADCs, four reconfigurable opamps, five programmable Serial Communication Blocks (SCBs), and eight TCPWM blocks. Used in industrial HMI touch panels requiring robust water-tolerant sensing and real-time motor control.
For engineers reviewing the CY8C4547AZQ-S473 datasheet, CY8C4547AZQ-S473 pinout, CY8C4547AZQ-S473 application, or CY8C4547AZQ-S473 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), 48-MHz CPU clock, 53 GPIO count, and SCB reconfigurability across I²C/SPI/UART protocols.
Technical Context
The device integrates a single-core Arm Cortex-M0+ CPU with hardware-accelerated divide/square-root units for motor control algorithms. Its analog subsystem includes two simultaneous-sampling SAR ADCs with channel sequencer and signal averaging, plus a dedicated capacitance-sensing sigma-delta ADC for CAPSENSE™.
Digital resources comprise eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, five run-time reconfigurable SCBs, and programmable logic blocks for Boolean operations on GPIOs - all routed via automatic digital interconnect fabric.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4548LQXI-S473 | 64-pin TQFP package; adds 2 extra SCBs and 16 additional GPIOs; same core/peripherals. | Suitable for designs needing more serial interfaces or dense sensor arrays. | Select when pin count or SCB quantity exceeds CY8C4547AZQ-S473 capacity; footprint not pin-compatible. |
| STM32G071KBT6 | No integrated CapSense; single 12-bit ADC (2.5 Msps); no programmable analog blocks; Cortex-M0+ at 64 MHz. | Requires external touch controller and opamp circuitry for comparable HMI functionality. | Choose for cost-sensitive, non-capacitive applications where analog flexibility is secondary to raw compute throughput. |
Compared with CY8C4547AZQ-S473, CY8C4548LQXI-S473 offers scalable I/O but larger footprint, while STM32G071KBT6 trades programmable analog integration for higher CPU speed and lower unit cost - making the former ideal for pin-growth paths and the latter for fixed-function embedded control.

FAQ
What debug interfaces does CY8C4547AZQ-S473 support?
CY8C4547AZQ-S473 uses Arm Serial-Wire Debug (SWD) with SWDCLK and SWDIO pins. It supports full programming, real-time debugging, and trace without JTAG. Debug circuits are enabled by default but can be disabled in firmware; re-enabling requires full chip erase and reprogramming.
Does CY8C4547AZQ-S473 support USB connectivity?
No, CY8C4547AZQ-S473 does not include a USB PHY or USB controller. Connectivity is limited to its five SCBs (I²C/SPI/UART) and optional external USB-to-UART bridge ICs. USB functionality must be implemented externally or via companion wireless SoCs.
Can the opamps operate during Deep Sleep mode?
Yes, all four opamps can remain active in Deep Sleep mode with 2.5 µA total system current. They support comparator mode and ADC input buffering, enabling continuous sensor monitoring and wake-on-event capability without CPU intervention.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only, schematic-driven). Both provide full peripheral configuration, CapSense tuning, and code generation. MiniProg4 is the recommended programmer/debugger; CY8CKIT-045S is the validated Pioneer Kit.
