Product details
Overview
CY8C4547AZI-S465 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 programmable opamps, five reconfigurable Serial Communication Blocks (SCBs), and eight TCPWM blocks. Used in industrial HMI, smart appliance touch interfaces, and motor control edge nodes where analog-digital co-processing and low-power operation are critical.
For engineers reviewing the CY8C4547AZI-S465 datasheet, CY8C4547AZI-S465 pinout, CY8C4547AZI-S465 application, or CY8C4547AZI-S465 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), 48-MHz CPU clock with single-cycle multiply, and GPIO flexibility (up to 53 pins with configurable drive modes and CapSense capability on any pin).
Technical Context
The device integrates a tightly coupled Arm Cortex-M0+ core with programmable analog (opamps, SAR ADCs, IDACs, comparators) and digital (PLD, TCPWM, SCB) subsystems, all routed via automatic interconnect fabric. Its CAPSENSE™ sigma-delta engine delivers hardware-accelerated capacitive sensing with SmartSense auto-tuning and water tolerance-enabling robust touch interfaces without external components.
Timing and control are enhanced by eight TCPWM blocks supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals for motor safety. The MCA (Motor Control Accelerator) includes dedicated hardware for square root and division, accelerating FOC and PFC algorithms directly in silicon.

| Capacitive Sensing Engine | Sigma-delta CAPSENSE™ with automatic SmartSense tuning - achieves production-ready touch performance without firmware calibration effort. |
| Reconfigurable Digital Logic | PLD-based Boolean logic on port I/O - implements custom glue logic (e.g., interrupt arbitration, status encoding) in hardware, not software. |
| Flexible Clock System | Multiple sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, 40-kHz ILO - enables precise timing for RTC, USB, and low-power wake-up with no external oscillators required. |
Applications
| Industrial HMI Panels | Smart Appliance Touch Interfaces |
|---|---|
Use Scenario: Touch-enabled control panels for PLCs, HMIs, and factory-floor displays operating in noisy EMI environments with humidity exposure. IC Role / Device Role / Timing Role: Primary MCU handling CapSense scanning, display interface (SPI/I²C), and real-time process control via TCPWM-driven indicators and relays. Use Value: Sigma-delta CAPSENSE™ delivers >5:1 SNR and water tolerance, eliminating false triggers during washdown cycles without shielded overlays or firmware recalibration. | Use Scenario: Touch controls on refrigerators, ovens, and washing machines requiring reliable operation across wide temperature ranges and mechanical stress. IC Role / Device Role / Timing Role: Single-chip solution managing capacitive buttons, LED backlight dimming (via TCPWM), and sensor data acquisition (temperature, door switch, current sense). Use Value: Deep Sleep mode draws only 2.5 µA while maintaining CapSense wake capability - extends battery life in cordless accessories and enables instant-on responsiveness. |
| Motor Control Edge Nodes | IoT Sensor Aggregation Gateways |
Use Scenario: Compact BLDC/PMSM motor drivers for fans, pumps, and compressors needing field-oriented control and overcurrent protection. IC Role / Device Role / Timing Role: Real-time controller executing FOC algorithm using MCA hardware acceleration, sampling dual ADC channels synchronously, and generating six-phase PWM with kill-signal safety. Use Value: Hardware sqrt/divide blocks reduce FOC loop execution time from ~12 µs (software) to <1.8 µs - enabling 20 kHz PWM switching with margin for communication overhead. | Use Scenario: Battery-powered environmental sensor hubs aggregating data from analog (temp/humidity), digital (I²C gas sensors), and pulse-input (flow meters) sources. IC Role / Device Role / Timing Role: Central aggregator running ModusToolbox™ middleware, managing low-power scheduling, secure OTA updates, and encrypted BLE/Wi-Fi offload via SCB peripherals. Use Value: Five independent SCBs allow concurrent I²C (sensor bus), UART (debug/log), and SPI (flash storage) - eliminating external bus expanders and reducing BOM count. |
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 |
|---|---|---|---|
| CY8C4548AZI-S475 | Same die, 64-pin TQFP package (0.5-mm pitch), 53 GPIOs retained - adds two extra SCBs and one additional TCPWM block. | Required when board layout needs more routing flexibility or additional serial interfaces beyond five SCBs. | Select for designs needing higher peripheral count or future-proofing with unused SCB/TCPWM resources. |
| CY8C4247LQI-BL483 | Lower-cost PSoC™ 4200L variant: 128 KB flash, 16 KB SRAM, no MCA, single SAR ADC, 32 GPIOs - lacks SmartSense and hardware sqrt/divide. | Suitable for basic touch + sensor readout where FOC or high-speed ADC is unnecessary. | Choose for cost-sensitive, non-motor applications where CAPSENSE™ and dual ADC are sufficient but MCA and extra memory are not needed. |
Compared with CY8C4548AZI-S475, this part offers identical core functionality in a smaller 48-pin footprint - ideal for space-constrained designs. Against CY8C4247LQI-BL483, it delivers 2× flash/SRAM, dual ADCs, MCA acceleration, and SmartSense tuning - justifying premium cost in motor control and advanced HMI use cases.

FAQ
What development tools are officially supported for CY8C4547AZI-S465?
Infineon officially supports both ModusToolbox™ (cross-platform, Eclipse-based, GitHub-integrated) and PSoC™ Creator (Windows-only, schematic-driven IDE). The CY8CKIT-045S Pioneer Kit provides hardware validation, while MiniProg4 enables programming/debugging via SWD. Both toolchains include full peripheral driver libraries (PDL), CapSense middleware, and FOC code examples aligned to this device's MCA and TCPWM blocks.
Does CY8C4547AZI-S465 support USB connectivity?
No, CY8C4547AZI-S465 does not include a USB PHY or dedicated USB controller. It relies on external USB-UART bridges (e.g., CP2102) or wireless co-processors (e.g., CYW20735) for host connectivity. Its five SCBs support UART, I²C, and SPI - making it compatible with USB bridge ICs via UART, but native USB device/host functionality is absent per the 002-26354 Rev. *E datasheet Section 2.5.
Can all 53 GPIOs be used simultaneously for CapSense™ sensing?
Yes, all GPIOs support CapSense™ functionality, but practical simultaneous sensing is limited by shared analog routing resources and sigma-delta modulator bandwidth. The datasheet confirms up to 64-capacitive-button scanning with SmartSense tuning, but full 53-pin concurrent sensing requires careful layout (guard traces, ground shielding) and firmware optimization to maintain >5:1 SNR - typical production deployments use 16–32 buttons with oversampling for noise immunity.
What is the maximum operating temperature for industrial use?
CY8C4547AZI-S465 is rated for –40°C to +85°C ambient operating temperature (industrial grade), verified per JEDEC JESD22-A104. This range applies to continuous operation with VDD = 1.71–5.5 V and all peripherals active. Thermal derating is not required within this range, and the device maintains full specification compliance including Deep Sleep current (2.5 µA) and CapSense SNR (>5:1) across the full span.
