Product details
Overview
CY8C4247AZI-L485 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 2.0B controllers - deployed in industrial HMI, motor control interfaces, and capacitive-sensing human-machine interfaces.
For engineers reviewing the CY8C4247AZI-L485 datasheet, CY8C4247AZI-L485 pinout, CY8C4247AZI-L485 application, or CY8C4247AZI-L485 equivalent, key selection criteria include Deep Sleep current (20 nA), CSD-based capacitive sensing SNR (>5:1), USB Full-Speed device support (12 Mbps), and 94 GPIOs with programmable drive strength and slew rate.
Technical Context
The CY8C4247AZI-L485 integrates a fixed-function Arm® Cortex®-M0 core with reconfigurable analog (CTBm opamps, SAR ADC, CSD blocks) and digital (UDBs, TCPWM, SCBs) subsystems. Its clock system includes IMO (8–48 MHz), ILO (32.768 kHz), and external crystal/PLL support for precise timing control.
It implements two independent CAN 2.0B controllers with message RAM and filtering, four SCBs supporting runtime-reconfigurable I²C/SPI/UART, and hardware-accelerated SmartSense™ for self-tuning capacitive sensing - enabling robust operation in noisy industrial environments without firmware recalibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - deterministic real-time execution with single-cycle multiply for motor control loops. |
| Memory | 256 kB flash + 32 kB SRAM - sufficient for bootloader, application code, and CAPSENSE™ tuning data storage. |
| Analog Peripherals | 4 opamps (CTBm), 2 comparators, 12-bit SAR ADC, 2 CSD blocks - supports simultaneous analog signal conditioning and high-SNR touch sensing. |
| Digital Peripherals | 8 UDBs, 8 TCPWM blocks, 4 SCBs, 2 CAN controllers - enables custom logic, PWM-driven motor phases, and dual-network diagnostics. |
| Power Modes | 20 nA Stop Mode, Deep Sleep with GPIO wakeup - enables battery-powered edge nodes with multi-year standby life. |
| GPIO | 94 programmable pins with configurable drive strength, slew rate, and CAPSENSE™/analog/digital routing - simplifies PCB layout and reduces external components. |
| USB Interface | Full-Speed (12 Mbps) device-only with Battery Charger Detect - enables direct connection to host PCs for firmware updates and HID-class HMI reporting. |
Pinout & Package
Package: 124-ball VFBGA (6 mm × 6 mm, 0.5 mm pitch). Pin mapping validated per Infineon datasheet 001-91686 Rev. *L, Table 3 (page 17).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | General-purpose I/O with CAPSENSE™/analog capability | Supports mutual-capacitance touch buttons and analog sensor inputs without external muxing. |
| P12[0]–P12[7] | CAN TX/RX differential pair pins | Dedicated physical layer interface for CAN FD-ready networks; internal termination resistors configurable. |
| USB_DP / USB_DM | USB 2.0 Full-Speed differential data lines | Integrated transceivers and pull-up resistor control eliminate external USB PHY components. |
| XRES | Active-low reset input | Asynchronous reset with glitch filter; compatible with pushbutton or microcontroller-initiated system recovery. |
| VDDA / VSSA | Analog power supply and ground | Separate analog domain ensures <1 LSB noise on 12-bit SAR ADC conversions during digital activity. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts baseline, sensitivity, and noise thresholds dynamically - eliminates manual firmware tuning across temperature/humidity. |
| Deep Sleep Analog Operation | Opamps and comparators remain active at 200 nA typical - enables wake-on-touch or analog threshold detection without full MCU wake. |
| Runtime-Reconfigurable SCBs | Four serial blocks can be independently assigned as I²C master/slave, SPI master/slave, or UART - reduces BOM count vs. discrete protocol ICs. |
| Programmable UDB Logic | Eight universal digital blocks each with 8 macrocells and 8-bit datapath - implement custom state machines (e.g., encoder interface, LED dimming sequencer) without CPU overhead. |
| Segment LCD Drive | Up to 64 outputs (common/segment), memory-mapped in Deep Sleep - drives alphanumeric displays in low-power instrumentation without display controller IC. |

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™ 4200L family; 68-pin QFN package, 256 kB flash, but no USB interface. | Lacks USB PHY - requires external USB-to-UART bridge for PC connectivity. | Select when USB is unnecessary and QFN assembly is preferred over VFBGA. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, no integrated CAPSENSE™ or UDBs. | Requires external touch controller and FPGA/CPLD for custom logic; higher performance but less analog integration. | Select when floating-point math or higher clock speed dominates over capacitive sensing and programmable analog. |
Compared with CY8C4247AZI-L485, CY8C4248LQI-BL553 trades USB for QFN packaging and simplified routing, while STM32G474RET6 offers superior compute throughput but demands external components for CAPSENSE™ and logic customization - making CY8C4247AZI-L485 optimal for tightly integrated, low-power HMI and sensor-edge designs.

FAQ
Does CY8C4247AZI-L485 support CAN FD?
No. The device integrates two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbps and standard/extended identifiers. CAN FD frame format, higher data rates, and flexible data length are not implemented in the PSoC™ 4200L silicon.
What development tools are required to program CY8C4247AZI-L485?
PSoC™ Creator IDE (discontinued but still supported) or ModusToolbox™ 3.x with PSoC™ 4 BSP is required. Programming uses SWD interface via KitProg3 or MiniProg4; no external JTAG adapter is needed. USB-based debug and programming are supported directly through the onboard USB interface.
Can all 94 GPIOs be used simultaneously as analog inputs?
No. While up to 94 pins support analog functionality, only 16 channels are routed to the 12-bit SAR ADC's multiplexer. Simultaneous analog sampling is limited to one channel at a time, though sequential scanning across multiple pins is supported via DMA-triggered sequences.
Is the USB interface capable of acting as a USB host?
No. The USB peripheral is device-only (not OTG or host-capable). It supports USB Full-Speed (12 Mbps) device classes including CDC, HID, and vendor-defined, but cannot enumerate or control USB peripherals like flash drives or keyboards.
