Product details
Overview
CY8C4247AZI-L433 from Infineon is a PSoC™ 4200L programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0 CPU, 256 kB flash, 32 kB SRAM, four opamps with comparator mode, and dual CAN controllers. It integrates programmable analog/digital blocks, capacitive sensing (CSD), and USB Full-Speed for embedded control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247AZI-L433 datasheet, CY8C4247AZI-L433 pinout, CY8C4247AZI-L433 application, or CY8C4247AZI-L433 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, dual CAN 2.0B compliance, CSD SNR >5:1, and USB Battery Charger Detect capability.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a dedicated DMA engine supporting 32 channels. Its analog subsystem includes four CTBm opamps-each configurable as amplifier, comparator, or ADC buffer-and two low-power comparators operational in Deep Sleep mode.
Digital flexibility derives from eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit data path, plus four reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART and two fixed-function CAN 2.0B controllers compliant with ISO 11898-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables deterministic real-time control in motor drive and sensor fusion. |
| Memory | 256 kB flash + 32 kB SRAM - supports complex firmware with bootloader, secure boot, and over-the-air update storage. |
| Power Modes | 20 nA Stop Mode with GPIO wakeup - extends battery life in portable industrial sensors and remote nodes. |
| Analog Peripherals | 4 opamps (CTBm), 2 comparators, 12-bit SAR ADC - enables simultaneous signal conditioning, threshold detection, and digitization without external components. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply rails | Independent 1.71–5.5 V domains per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU logic + 1.8 V sensor interface). |

| USB_DP / USB_DM | USB 2.0 Full-Speed differential pair | Integrated transceiver with Battery Charger Detect (BCD) protocol support - eliminates need for external USB charger ID IC. |
| XRES | External reset input | Active-low asynchronous reset pin compatible with pushbutton or supervisor IC; internal pull-up ensures defined state on power-up. |
| P0[0]–P15[7] | Programmable GPIO bank | Each pin supports CAPSENSE™, analog input/output, digital logic, or serial peripheral function - routed via automatic interconnect matrix. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts baseline and sensitivity in real time - eliminates manual tuning across temperature/humidity variations. |
| Deep Sleep Analog Operation | Opamps and comparators remain active at 20 nA total system current - enables always-on touch wake-up or low-power sensor monitoring. |
| Reconfigurable SCBs | Four serial blocks dynamically switch between I²C master/slave, SPI master/slave, or UART modes at runtime - reduces firmware complexity in multi-protocol gateways. |
| UDB-Based Logic | Eight universal digital blocks implement custom state machines or glue logic in hardware - offloads timing-critical tasks from CPU and improves determinism. |
| Segment LCD Drive | Up to 64 outputs (common/segment) with 4-bit memory per pin in Deep Sleep - supports low-power industrial displays without external driver IC. |

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™ 4200L family; 512 kB flash, 64 kB SRAM, 124-ball VFBGA - higher memory density and same package footprint. | Required for larger firmware images (e.g., Bluetooth stack + OTA), but not needed for basic CAN+CAPSENSE™ HMI. | Select when firmware size exceeds 256 kB or future scalability demands more RAM for real-time analytics. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, no integrated CAPSENSE™ or CSD; requires external touch controller and CAN transceiver. | Suitable for high-performance motor control but lacks native capacitive sensing and dual CAN integration. | Choose when floating-point math or DSP acceleration is critical, and external analog/digital components are acceptable for BOM cost trade-off. |
Compared with CY8C4247AZI-L433, CY8C4248LQI-BL553 offers memory headroom without changing PCB layout, while STM32G474RET6 trades integrated peripherals for raw CPU performance - making the former ideal for scalable embedded UIs and the latter better suited for compute-intensive control loops.

FAQ
Does CY8C4247AZI-L433 support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 device transceiver compliant with USB Specification Rev. 2.0, including built-in termination resistors, differential signaling, and Battery Charger Detect (BCD) circuitry. No external PHY or level-shifting components are required for standard USB device operation.
What is the maximum operating temperature for CY8C4247AZI-L433 in industrial applications?
CY8C4247AZI-L433 is rated for operation from –40 °C to +85 °C ambient temperature, meeting industrial-grade reliability requirements. Its thermal design supports continuous operation at full 48 MHz CPU speed within this range, with validated performance across voltage (1.71–5.5 V) and temperature extremes.
Can the CSD blocks perform mutual-capacitance touch sensing?
No. The two CSD blocks in CY8C4247AZI-L433 support only self-capacitance sensing using sigma-delta modulation. Mutual capacitance requires PSoC™ 4100S or PSoC™ 6 devices with dedicated CapSense CSD v2.0 hardware and associated firmware libraries.
Is there hardware support for secure boot or cryptographic acceleration?
No. CY8C4247AZI-L433 does not include hardware AES engines, TRNG, or secure boot ROM. Security relies on software-based implementations (e.g., bootloader signature verification using SHA-256 in firmware) and external secure elements if required for certification.
