CY8C4247AZI-M485 Overview
What is a PSoC 4 microcontroller? A PSoC (Programmable System-on-Chip) 4 is a low-power mixed-signal MCU family that pairs an ARM Cortex-M0 CPU core with a fabric of programmable analog blocks (opamps, comparators, ADCs, DACs) and universal digital blocks (UDBs). Within the PSoC 4 taxonomy it sits under PSoC 4200M -> PSoC 4 -> PSoC family -> 32-bit MCU -> microcontroller -> semiconductor, occupying the same architectural family as PSoC 4000S, 4100S, 4200L and 4100M parts.
Key features of the CY8C4247AZI-M485 include an ARM Cortex-M0 core with single-cycle multiply, 128 kByte Flash / 16 kByte SRAM, programmable analog via on-chip opamps/comparators/12-bit SAR ADC and IDACs, CapSense® capacitive touch sensing hardware, up to 51 GPIO, multiple communication peripherals (SCB blocks configurable as UART/SPI/I2C), and a 2.5 V - 5.5 V wide supply range suitable for direct 5V system designs.
Technically the device uses a 40 nm low-power process with an integrated Cortex-M0 core, hardware multiply (single-cycle 32x32), a 12-bit 1 Msps SAR ADC, up to four opamps, two low-power comparators, two 8-bit IDAC blocks, four TCPWM blocks for PWM/counter/quadrature decode, and five configurable serial communication blocks (SCBs) that each map to UART, SPI or I2C. The PSoC Creator / ModusToolbox toolchain exposes the analog and digital fabric as graphical components, allowing designers to instantiate peripherals and route signals on-chip.
Typical applications include HVAC/air-con indoor and outdoor unit control, white-goods motor control, smart home sensor hubs, industrial HMI panels, and CapSense touch-button user interfaces. The wide 2.5 V - 5.5 V supply range allows direct connection to 5 V rails without level shifters.
When designing with this part, place a 1 µF decoupling cap on each VDD/VCCD pair, follow the PSoC 4200M hardware design guide for the SWD/JTAG programming header, and confirm the 10x10 mm TQFP land pattern matches the package library before committing the PCB layout.

Typical Applications
CY8C4247AZI-M485 is suitable for 6 applications: HVAC Air-Conditioner Control, Capacitive Touch User Panels, White-Goods Motor Control, Smart Home Sensor Hubs, Industrial HMI Panels, IoT Edge Sensor / Wearable Devices.
HVAC Air-Conditioner Control
The CY8C4247AZI-M485 is positioned by Infineon specifically for HVAC/air-con applications per its product page. Its 4 TCPWM blocks drive brushless-DC inverter switching at up to 48 MHz, while the 12-bit 1 Msps SAR ADC samples motor current and thermistor feedback in real time. The on-chip opamps condition current-sense signals, the 2.5-5.5 V supply accepts 5 V rails directly, and the 51 GPIO handle key panels, LED indicators, and UART/I2C communication with outdoor units. The wide supply range removes the need for level shifters on legacy 5 V HVAC logic. A typical inverter control loop runs in under 5 us thanks to the single-cycle multiply on the Cortex-M0 core.
Recommended
Capacitive Touch User Panels
The CY8C4247AZI-M485 integrates 4th-generation CapSense hardware that supports touch buttons, sliders, and proximity sensors without an external touch controller. The on-chip IDACs and comparators implement the CSD/CSA charge-transfer scanning, while the 51 GPIO host both CapSense electrodes and LEDs through the same TCPWM blocks. The Cortex-M0 core executes the CapSense middleware in firmware, freeing the design from external I2C/SPI touch ICs. Power consumption in deep-sleep with wake-on-touch is microamp-level current, making the part suitable for battery-backed panels. Designers using PSoC Creator can drag-and-drop CapSense components with auto-routing to GPIO and IDAC blocks.
Recommended
White-Goods Motor Control
Washing machines, dishwashers, and refrigerator compressors benefit from the CY8C4247AZI-M485's 4 TCPWM blocks, 12-bit ADC, and 51 GPIO in a 64-TQFP package. The Cortex-M0 at 48 MHz runs field-oriented-control firmware for BLDC motors, while the on-chip opamps handle current-sense amplification without external analog front-ends. The 2.5-5.5 V supply tolerance accommodates 3.3 V digital logic and 5 V analog sensor rails on the same PCB. The 128 kByte Flash supports motor-control libraries plus a safety monitor stack. Designers should follow PSoC 4200M hardware design guide routing for the SWD/JTAG programming header during PCB layout.
Recommended
Smart Home Sensor Hubs
Smart-home gateways aggregating multiple sensors (temperature, humidity, occupancy, air-quality) leverage the CY8C4247AZI-M485's 5 SCB blocks (each routable as UART/SPI/I2C) to host radios, sensors, and host controllers simultaneously. The 12-bit ADC reads analog sensors while the Cortex-M0 runs the application stack in 128 kByte Flash. The 2.5-5.5 V supply simplifies integration with both 3.3 V radios and 5 V analog front-ends on the same board. The 51 GPIO support status indicators plus multiple sensor interrupts. The PSoC 4200M family includes low-power sleep current suited to battery-backed hub designs.
Recommended
Industrial HMI Panels
Industrial human-machine-interface panels with keypads, displays, and indicator stacks are well-served by the CY8C4247AZI-M485's 51 GPIO and 5 SCB peripherals. Designers route a character LCD or segment display through one SCB, LEDs/PWM through TCPWM, and an industrial bus (RS-485 UART) through another. The 12-bit ADC reads analog front-panel potentiometers and 4-20 mA inputs through onboard comparators. The wide 2.5-5.5 V supply simplifies industrial 24 V interface designs with onboard regulation. Flash size supports IEC 61131-3-style PLC runtime plus comms stacks in 128 kByte. The 64-TQFP footprint suits compact panel designs.
Recommended
IoT Edge Sensor / Wearable Devices
Low-power IoT edge nodes and wearable devices benefit from the CY8C4247AZI-M485's low-power Cortex-M0 core and deep-sleep modes. The part's multiple SCB blocks host I2C sensors (accelerometer, heart-rate, environmental) plus a BLE/NFC companion radio. The 12-bit ADC reads analog sensor outputs while the Cortex-M0 runs BLE beacon or sensor-fusion algorithms. The 51 GPIO supports multiple sensors and user-interface elements on the same board. The wide 2.5-5.5 V supply allows direct Li-ion battery connection (3.7 V nominal) without complex power conditioning. Designers should verify the deep-sleep current budget against battery life targets during early prototyping.

Key Differentiators
- Highest-density 4200M 64-TQFP variant (vs CY8C4246AZI-M445)
- Motor-control-optimized 4200M fabric vs general-purpose 4100S (vs CY8C4124PVI-432T)
- Active HVAC/air-con positioning (vs CY8C4247AZI-L485)
Design Notes
Place a 1 uF decoupling capacitor on each VDDD/VCCD pair and a 1 uF cap on VDDA/VSSA. VCCD is the internal 1.8 V LDO output and MUST be decoupled with at least 1 uF (X5R/X7R) directly at the VCCD pin. Keep analog and digital ground returns separate under the chip and join them at a single point near the VDDA/VSSA pins to minimize digital switching noise coupling into ADC measurements.
Follow the PSoC 4200M hardware design guide for the SWD/JTAG header: route SWDIO and SWDCK to a 10-pin Cortex Debug connector with 100 mil pitch. The 64-TQFP package (10x10 mm) has 0.5 mm pitch pins - use 0.20 mm trace/space with 0.30 mm via drill for fan-out. Place decoupling caps on the opposite PCB side directly under VDD/VCCD/VSS pins using short vias.
Do NOT leave the XRES pin floating - it MUST be pulled high through a 4.7 kohm resistor to VDDD. The XRES pin is active-low; if not pulled up, the device will randomly enter reset mode. For CapSense designs, route sense traces as guarded traces (ground fill on both sides) and avoid routing them parallel to noisy digital switching signals to prevent false touches.
Estimated: At 48 MHz clock with all peripherals active in industrial 64-TQFP (theta_JA ~ 50 C/W typical), the part dissipates under 100 mW so no heatsink is needed. For applications where TCPWM blocks drive high-frequency switching at full GPIO load, monitor die temperature through the built-in temperature sensor diode to ensure junction stays below 85 C (industrial) or 70 C (extended) operation.
Compliance Information
RoHS and REACH compliant per Infineon product page; lead-free and halogen-free per Infineon packaging materials disclosure. Standard part is not AEC-Q100 qualified - automotive designers should request the automotive-grade CY8C4247AZI-M485ES or equivalent from Infineon.
