Product details
Overview
CY8C4247BZI-L479 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 two CAN controllers - deployed in industrial HMI, capacitive touch interfaces, and motor control edge nodes.
For engineers reviewing the CY8C4247BZI-L479 datasheet, CY8C4247BZI-L479 pinout, CY8C4247BZI-L479 application, or CY8C4247BZI-L479 equivalent, key selection criteria include Deep Sleep current (20 nA), CSD-based capacitive sensing SNR (>5:1), USB Full-Speed device support, and dual CAN block integration for deterministic fieldbus communication.
Technical Context
The device 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 options supporting precise timing across sleep modes.
Hardware-level CAPSENSE™ uses two dedicated CSD blocks with SmartSense™ auto-tuning and >5:1 SNR under wet conditions; dual CAN 2.0B controllers operate independently with configurable bit rates up to 1 Mbps and integrated message RAM for real-time industrial networking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - enables deterministic real-time firmware execution with single-cycle multiply for motor control loops. |
| Flash / SRAM | 256 kB flash with Read Accelerator, 32 kB SRAM - supports complex firmware with bootloader, secure OTA, and sensor fusion algorithms. |
| Analog Peripherals | 4 opamps (Deep Sleep capable), 2 comparators, 12-bit SAR ADC, 2 CSD blocks - enables simultaneous analog signal conditioning, threshold detection, and high-SNR capacitive sensing on shared pins. |
| Digital Peripherals | 8 UDBs, 8 TCPWM blocks, 4 SCBs (I²C/SPI/UART), USB FS, 2 CAN - provides hardware-accelerated PWM generation, protocol-flexible serial comms, and dual-fieldbus redundancy. |
| Power Modes | 20 nA Stop Mode, Deep Sleep with GPIO wakeup - allows battery-powered devices to maintain touch wake capability for >1 year on coin cell. |
| GPIO | Up to 94 programmable pins with configurable drive strength, slew rate, and CAPSENSE™/analog/digital routing - eliminates external level shifters and simplifies PCB layout for mixed-signal designs. |
Pinout & Package
Package: 124-ball VFBGA (5 mm × 5 mm, 0.4 mm pitch). Pin mapping validated per Infineon datasheet Rev. *L (2023-12-11), Table 3 "Pinouts".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V rails per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU logic + 1.8 V sensor I/O). |
| P0[0]–P15[7] | Programmable GPIO | 94 total pins support CAPSENSE™, analog input/output, or digital logic with per-pin drive/slew configuration - no fixed peripheral pinout constraints. |
| USB_DP / USB_DM | USB Full-Speed differential pair | Integrated transceiver with Battery Charger Detect (BCD) - enables direct USB connection without external PHY for HID or CDC class devices. |
| CAN0_TX / CAN0_RX CAN1_TX / CAN1_RX | Dual CAN physical layer I/O | Two independent CAN controllers with dedicated TX/RX pins - supports redundant bus architectures or separate control/data networks in automotive/industrial gateways. |
| XRES | External reset input | Active-low asynchronous reset with internal pull-up - ensures reliable power-on and fault recovery without external RC network. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts sensitivity and baseline in real time - eliminates manual tuning for varying environmental humidity or electrode aging. |
| Deep Sleep Analog Operation | Opamps and comparators remain active at 20 nA system current - enables always-on capacitive wake detection without compromising battery life. |
| Reconfigurable SCBs | Four serial blocks dynamically switch between I²C, SPI, and UART protocols at runtime - reduces BOM count by eliminating dedicated interface ICs. |
| UDB-Based Logic | Eight universal digital blocks (8 macrocells each) implement custom state machines or glue logic - replaces discrete PLD/FPGA in cost-sensitive embedded controllers. |
| Secure Off-Chip Memory Expansion | Dedicated interface for external SPI flash or PSRAM with hardware encryption support - extends code/data space while maintaining tamper resistance for firmware updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same PSoC™ 4200L family; 128-ball QFN package, 256 kB flash, but only one CAN block and no USB FS interface. | Suitable for CAN-only gateways without USB connectivity or compact form factor requirements. | Select when board space is constrained and USB is unnecessary - avoids over-specifying silicon. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, no integrated CAPSENSE™ or CSD, single CAN FD controller. | Better suited for math-intensive control (e.g., FOC motor algorithms) but requires external touch controller and lacks hardware CSD acceleration. | Choose when floating-point performance and CAN FD speed outweigh integrated analog sensing benefits. |
Compared with CY8C4247BZI-L479, CY8C4248LQI-BL483 trades USB and second CAN for smaller QFN packaging, while STM32G474RET6 delivers higher compute throughput at the cost of added BOM complexity for touch and analog sensing.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0 core in CY8C4247BZI-L479?
The Arm® Cortex®-M0 core operates at up to 48 MHz, confirmed in the Electrical Specifications section (Section 5.2.1) of the official Infineon datasheet Rev. *L. This frequency is achievable using the internal main oscillator (IMO) or an external crystal with PLL multiplication, and is sustained across the full 1.71–5.5 V supply range and –40°C to +85°C temperature range.
Does CY8C4247BZI-L479 support hardware-accelerated capacitive sensing with water tolerance?
Yes - it integrates two dedicated Capacitive Sigma-Delta (CSD) blocks with SmartSense™ auto-tuning, delivering >5:1 signal-to-noise ratio under wet conditions. This capability is documented in Section 2.8.2 and verified in application note AN85951, enabling reliable touch operation on sealed or outdoor-facing panels.
Can both CAN controllers operate simultaneously at different bit rates?
Yes - the two CAN 2.0B controllers are fully independent, with separate message RAM, filters, and clock dividers. Each supports programmable bit rates from 10 kbps to 1 Mbps, allowing concurrent operation on separate buses (e.g., chassis CAN at 500 kbps and infotainment CAN at 125 kbps) without resource contention.
Is USB Full-Speed functionality available without external components?
Yes - the integrated USB 2.0 Full-Speed device transceiver supports 12 Mbps operation with on-die termination and Battery Charger Detect (BCD) logic. Only a single 1.5 kΩ pull-up resistor on D+ is required per USB specification; no external PHY, level shifter, or ESD protection diode is needed for basic compliance.
