Product details
Overview
CY8C4247AXI-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, and reconfigurable analog/digital blocks. It supports capacitive sensing (CSD), segment LCD drive, dual CAN interfaces, and operates from 1.71–5.5 V across –40°C to +105°C for industrial motor control and HMI applications.
For engineers reviewing the CY8C4247AXI-M485 datasheet, CY8C4247AXI-M485 pinout, CY8C4247AXI-M485 application, or CY8C4247AXI-M485 equivalent, this page delivers verified specifications, validated package mapping, confirmed pin functions, real-world use cases, and technically grounded alternative options - all derived from Infineon's official 001-93963 Rev. *M datasheet.
Technical Context
The device implements a tightly coupled architecture where the 48 MHz Cortex-M0 core coordinates with four Universal Digital Blocks (UDBs), each containing 8 macrocells and an 8-bit datapath, enabling user-defined state machines or peripheral logic. Analog resources include four opamps with comparator/ADC-buffering modes and two low-power comparators - all functional in Deep Sleep mode at ≤20 nA.
Digital peripherals are highly flexible: four Serial Communication Blocks (SCBs) support runtime-reconfigurable I²C/SPI/UART, while two independent CAN 2.0B controllers provide deterministic industrial networking. The 12-bit SAR ADC achieves 1-Msps conversion with hardware-accelerated CSD for >5:1 SNR capacitive touch sensing.
Key Specifications

Use Value: Deep Sleep mode with GPIO wakeup (<20 nA) extends battery life in portable units; medical-grade CSD SNR (>5:1) prevents false triggers from ECG/EEG interference. |
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 |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M family; 256 kB flash, 32 kB SRAM, but 48-pin QFN package (fewer GPIOs, no CAN) | Lacks dual CAN and has reduced pin count - suitable for cost-sensitive, non-networked embedded UIs only. | Select when higher memory headroom is needed but CAN and full GPIO count are unnecessary. |
| STM32G474RET6 | Arm Cortex-M4 @ 170 MHz, 512 kB flash, 128 kB SRAM, no integrated capacitive sensing or programmable analog/digital fabric | Requires external components for touch sensing and analog signal chain - increases BOM and layout complexity. | Choose for compute-intensive tasks (e.g., motor control with observer algorithms) where raw DSP throughput outweighs integration benefits. |
Compared with CY8C4247AXI-M485, CY8C4248LQI-BL553 trades CAN and pin count for memory scalability, while STM32G474RET6 offers higher CPU performance at the expense of analog/digital configurability and touch integration - making CY8C4247AXI-M485 optimal for compact, sensor-rich, CAN-connected industrial edge nodes.

FAQ
Does CY8C4247AXI-M485 support USB device functionality?
No. The CY8C4247AXI-M485 does not include a USB PHY or USB controller. Its serial communication blocks (SCBs) support only I²C, SPI, and UART protocols. For USB connectivity, external bridge ICs (e.g., CP2102N) or migration to PSoC™ 4 BLE/USB families would be required.
What debug interfaces are supported, and is JTAG available?
CY8C4247AXI-M485 supports only ARM Serial Wire Debug (SWD) via SWDCLK and SWDIO pins - no JTAG interface is implemented. SWD provides full programming, breakpoint, and real-time variable access using standard CMSIS-DAP or Segger J-Link probes compatible with PSoC™ Creator and ModusToolbox™.
Can the on-chip opamps drive speakers or high-current loads directly?
No. Each opamp delivers ≤25 mA output current and is optimized for signal conditioning, ADC buffering, or comparator reference generation - not power amplification. Driving speakers or relays requires external driver stages. The GPIOs support high-current drive modes (up to 25 mA sink/source), but opamp outputs must not be shorted or loaded beyond datasheet limits.
Is the CSD capacitive sensing engine certified for IEC 61000-4-6 conducted immunity?
Infineon validates CSD performance per IEC 61000-4-3 (radiated immunity) and IEC 61000-4-2 (ESD), but IEC 61000-4-6 compliance depends on board-level design - including proper grounding, shielded traces, and ferrite filtering on supply lines. The device's >5:1 SNR and hardware SmartSense improve robustness, yet full system-level testing is mandatory for certification.
