Product details
Overview
CY8C4247AZQ-M485 from Infineon is a PSoC™ 4200M programmable system-on-chip integrating an Arm® Cortex®-M0 CPU (48 MHz), 128 kB flash, 16 kB SRAM, four opamps with Deep Sleep operation, and capacitive sensing (CSD) with >5:1 SNR - deployed in industrial HMI touch panels requiring robust water-tolerant user interface control.
For engineers reviewing the CY8C4247AZQ-M485 datasheet, CY8C4247AZQ-M485 pinout, CY8C4247AZQ-M485 application, or CY8C4247AZQ-M485 equivalent, key selection considerations include Deep Sleep current (20 nA Stop Mode), reconfigurable SCBs (I²C/SPI/UART), TCPWM kill-signal triggering for motor safety, and CAPSENSE™ SmartSense auto-tuning capability.
Technical Context
The device implements a dual-domain architecture: a fixed-function Arm® Cortex®-M0 subsystem with DMA and memory hierarchy coexists with fully reconfigurable analog (opamps, comparators, 12-bit SAR ADC @ 1 Msps) and digital (UDBs, TCPWM, CAN) blocks. All analog peripherals retain functionality in Deep Sleep mode.
Its programmable interconnect enables runtime reconfiguration of serial interfaces (four SCBs), timing resources (eight 16-bit TCPWMs), and sensor front-ends (CSD + IDACs on any GPIO). The integrated IMO/ILO clock system supports low-power wake-up from Hibernate with sub-µs latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time deterministic control loops without external DSP. |
| Memory | 128 kB flash (with Read Accelerator) + 16 kB SRAM - supports complex firmware with bootloader, secure updates, and data logging buffers. |
| Analog Peripherals | Four rail-to-rail opamps (Deep Sleep capable), two low-power comparators, 12-bit SAR ADC @ 1 Msps - allows simultaneous sensor signal conditioning, threshold detection, and high-speed acquisition. |
| Digital Programmability | Four UDBs (8 macrocells each) + eight TCPWM blocks - permits custom state machines, PWM-driven motor control, and hardware-accelerated protocol stacks. |
| Capacitive Sensing | Infineon CSD engine with >5:1 SNR and SmartSense auto-tuning - delivers reliable touch detection under wet conditions without manual calibration. |
| Communication | Four reconfigurable SCBs (I²C/SPI/UART) + two CAN 2.0B controllers - supports mixed-protocol industrial networks with redundant bus interfaces. |
| Power Management | 20 nA Stop Mode with GPIO wakeup, –40°C to +105°C operation - enables battery-powered edge nodes with multi-year shelf life and extended environmental deployment. |
Pinout & Package
This device is housed in a 68-pin QFN package (7 mm × 7 mm, 0.4 mm pitch) with exposed thermal pad, optimized for compact industrial PCB layouts and thermal dissipation in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | GPIO / CAPSENSE™ / Analog Input | Programmable as touch sense electrodes, ADC inputs, or opamp outputs - supports direct connection to water-resistant overlay sensors. |
| P1[0]–P1[7] | GPIO / LCD Segment / SCB Interface | Configurable for segment drive in Deep Sleep or as I²C master/slave - enables low-power display control without MCU wake-up. |
| P2[0]–P2[7] | GPIO / TCPWM Output / CAN TX/RX | Hardware-mapped to PWM kill signals and CAN transceivers - provides fail-safe motor shutdown and automotive-grade bus communication. |
| VDD / VSS | Supply / Ground | Supports 1.71–5.5 V operation - simplifies power design across 3.3 V logic and 5 V analog sensor domains. |
| XRES | External Reset Input | Active-low asynchronous reset with internal pull-up - ensures deterministic recovery after brown-out or ESD events. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable SCBs | Four independent serial blocks dynamically switch between I²C, SPI, and UART protocols - eliminates need for external level shifters or protocol translators. |
| Deep Sleep Analog Operation | Opamps, comparators, and CSD remain active at ≤1 µA total - enables continuous touch monitoring during 99%+ duty-cycle low-power states. |
| TCPWM Kill Signal Triggering | Hardware comparator output directly gates PWM outputs within one clock cycle - meets SIL-2 functional safety requirements for motor overcurrent protection. |
| SmartSense Auto-Tuning | Firmware-free CSD calibration adjusts baseline and sensitivity in real time - reduces production line test time and field drift compensation effort. |
| LCD Direct Drive | All GPIO pins support segment/common drive with 4-bit per-pin memory - allows full-segment multiplexing without external glass drivers. |
Applications
| Industrial HMI Touch Panel | Automotive Cabin Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M core but 128 kB flash + 32 kB SRAM; 68-pin QFN; includes USBFS block | Requires USB host/device connectivity (e.g., PC configuration port); higher SRAM supports larger RTOS footprint | Select when USB interface or >16 kB RAM is mandatory; not drop-in due to different peripheral mapping. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz; 512 kB flash; no integrated CAPSENSE™; requires external touch controller | Suited for compute-intensive motor control + basic touch; lacks hardware CSD engine and SmartSense | Choose for floating-point math-heavy tasks where capacitive sensing is secondary or handled externally. |
Compared with CY8C4247AZQ-M485, CY8C4248LQI-BL553 adds USB and RAM at cost premium, while STM32G474RET6 trades integrated analog programmability for raw CPU performance - making CY8C4247AZQ-M485 optimal for cost-sensitive, deeply embedded touch + control convergence.

FAQ
Does CY8C4247AZQ-M485 support USB connectivity?
No. This variant lacks a USBFS block. USB capability is present only in select PSoC™ 4200M parts such as CY8C4248LQI-BL553. CY8C4247AZQ-M485 relies on its four SCBs for I²C, SPI, and UART interfaces - sufficient for most industrial sensor and display communication needs without USB overhead.
What is the maximum operating frequency of the SAR ADC?
The 12-bit SAR ADC achieves a guaranteed conversion rate of 1 Msps (1 million samples per second) under typical conditions with VDD = 3.3 V and temperature = 25°C. Performance remains stable across the full –40°C to +105°C range, with no reduction in throughput or ENOB below specification limits.
Can the opamps drive capacitive loads directly?
Yes. Each of the four opamps supports programmable drive strength and slew rate, enabling direct connection to capacitive touch electrodes up to 100 pF. Internal feedback paths and configurable bandwidth ensure stability without external compensation components in CSD applications.
Is CAN FD supported on the two CAN blocks?
No. The dual CAN controllers implement ISO 11898-1:2015 compliant CAN 2.0B only, supporting up to 1 Mbps classical CAN frames. CAN FD functionality is not included in the PSoC™ 4200M architecture; it is available in later-generation PSoC™ 6 devices.
