Product details
Overview
CY8C4247AXQ-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 CY8C4247AXQ-M485 datasheet, CY8C4247AXQ-M485 pinout, CY8C4247AXQ-M485 application, or CY8C4247AXQ-M485 equivalent, key selection criteria include Deep Sleep power (20 nA Stop Mode), SAR ADC performance (12-bit, 1-Msps), TCPWM flexibility (8× 16-bit blocks), and CAPSENSE™ water tolerance with SmartSense auto-tuning.
Technical Context
The device implements a tightly coupled architecture where the Cortex®-M0 core interfaces directly with UDBs (universal digital blocks) and analog subsystems via programmable interconnect. Its clock system includes IMO (internal main oscillator) at 48 MHz, ILO (internal low-speed oscillator) at 32.768 kHz, and external crystal support up to 33 MHz.
Analog resources include four opamps with comparator/ADC buffer modes, two low-power comparators active in Deep Sleep, and a 12-bit SAR ADC with configurable input muxing and 1-Msps conversion rate. Digital peripherals feature four SCBs (reconfigurable as I²C/SPI/UART) and two dedicated CAN 2.0B controllers supporting industrial networking.

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 family; 256 kB flash, 32 kB SRAM, 68-pin QFN, but lacks dual CAN blocks - only one SCB configured as CAN. | Suitable for non-automotive applications needing higher memory but no redundant CAN bus. | Select when firmware complexity demands >128 kB flash and dual CAN is unnecessary. |
| STM32G474RET6 | Arm Cortex-M4 @ 170 MHz, 512 kB flash, 128 kB SRAM, integrated analog (opamp, comparator, 12-bit ADC @ 2.4 Msps), but no CAPSENSE™ or programmable logic. | Better for compute-intensive control loops; requires external components for robust capacitive sensing or custom digital logic. | Choose when floating-point performance and high-speed ADC throughput outweigh programmable analog/digital flexibility. |
Compared with CY8C4247AXQ-M485, CY8C4248LQI-BL553 trades dual CAN for doubled memory capacity, while STM32G474RET6 offers superior CPU performance and ADC speed but lacks hardware-accelerated capacitive sensing and reconfigurable logic - making it less optimal for touch-integrated, low-power industrial HMIs.

FAQ
Does CY8C4247AXQ-M485 support USB connectivity?
No, CY8C4247AXQ-M485 does not include a USB PHY or controller. It relies on its four SCBs for I²C, SPI, and UART interfaces. For USB host/device functionality, external bridge ICs (e.g., CP2102N or FT232H) must be used in conjunction with UART-based SCB configuration.
What development tools are required to program this device?
Programming requires Infineon's PSoC™ Creator IDE (legacy) or ModusToolbox™ (current). Both support schematic-based design entry, automatic routing, and API-driven peripheral configuration. Debugging uses standard ARM SWD via KitProg3 or MiniProg4 programmers connected to SWDCLK/SWDIO pins.
Can the on-chip opamps drive speakers or high-current loads directly?
No - the integrated opamps are optimized for signal conditioning (e.g., sensor amplification, ADC buffering) and deliver ≤25 mA output current. They lack the voltage swing, thermal headroom, or short-circuit protection needed for speaker driving; external Class-D or AB amplifiers are required for audio output.
Is the CAPSENSE™ implementation compliant with IEC 61000-4-6 conducted immunity standards?
Yes - the CSD engine includes hardware-based spread-spectrum modulation and adaptive baseline tracking, enabling designs meeting IEC 61000-4-6 Level 3 (10 V/m, 150 kHz–80 MHz) when implemented per Infineon's layout guidelines (e.g., guard rings, shield traces, proper grounding) and validated using CY8CKIT-149 development kit test reports.
