Product details
Overview
CY8C4248FLI-BL583T from Infineon is a PSOC™ 4 programmable system-on-chip integrating an Arm® Cortex®-M0+ CPU, configurable analog and digital peripherals, 256 KB flash, 32 KB SRAM, and CapSense™ capacitive sensing capability. It operates at up to 48 MHz, supports USB 2.0 full-speed device interface, and includes hardware-based cryptographic acceleration (AES-128). It is used in human-interface devices such as touch-enabled industrial HMI panels.
For engineers reviewing the CY8C4248FLI-BL583T datasheet, CY8C4248FLI-BL583T pinout, CY8C4248FLI-BL583T application, or CY8C4248FLI-BL583T equivalent, key selection criteria include CapSense™ channel count, USB device stack support, flash retention over 100k cycles, and availability of hardware TRNG and CRC modules for secure firmware updates.
Technical Context
This device belongs to the PSOC™ 4200 family and implements a dual-bus architecture with separate AHB-Lite and APB buses for concurrent CPU and peripheral operation. It integrates a programmable analog block (PSoC™ Analog Coprocessor) supporting op-amps, comparators, and SAR ADCs up to 12-bit/1 Msps, alongside a programmable digital block (UDB) enabling custom logic, state machines, and communication protocols including I²C, SPI, and UART.
The chip features a dedicated CapSense™ subsystem with SmartSense™ auto-tuning, supporting up to 62 self-capacitive or 48 mutual-capacitive sensors. Its USB 2.0 PHY includes internal transceivers and supports suspend/resume, bus-powered operation, and endpoint FIFOs - eliminating need for external USB level-shifting or termination components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz - enables deterministic real-time control with Thumb-2 instruction set and low-latency interrupt handling. |
| Flash / SRAM | 256 KB flash (100k write/erase cycles, 20-year data retention) + 32 KB SRAM - sufficient for complex CapSense™ + USB + BLE host stack coexistence. |
| CapSense™ Channels | Up to 62 self-cap or 48 mutual-cap sensors - supports multi-touch sliders, proximity wake-up, and noise-immune button arrays in EMI-prone environments. |
| USB Interface | Full-speed (12 Mbps) device-only with integrated PHY and 512-byte endpoint buffer - eliminates external USB transceiver and simplifies PCB layout. |
| Analog Peripherals | 12-bit SAR ADC (1 Msps), 2 op-amps, 2 comparators, IDACs - enables sensor signal conditioning and closed-loop analog control without external ICs. |
| Security Features | AES-128 hardware accelerator, TRNG, CRC unit, flash protection bits - supports secure boot, encrypted firmware updates, and tamper-resistant HMI authentication. |
Pinout & Package
Package: 68-pin QFN (10 mm × 10 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad. RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | GPIO / CapSense™ CSD / UART0 RX/TX | Configurable digital I/O with CapSense™ shield and sense capability; supports hardware UART with automatic baud rate detection. |

Key Features
| Feature | Design Value |
|---|---|
| Programmable UDB Array | Enables custom digital logic (e.g., PWM generators, protocol engines) without FPGA or external glue logic - reduces BOM and board area. |
| SmartSense™ Auto-Tuning | Automatically calibrates CapSense™ baseline and thresholds across temperature/humidity drift - eliminates manual tuning in production test. |
| Hardware AES-128 + TRNG | Accelerates encryption/decryption by >10× vs software-only; TRNG meets NIST SP800-90B entropy requirements for secure key generation. |
| Low-Power Deep-Sleep Mode | Consumes 1.3 µA typical with RTC running and 8 KB SRAM retained - extends battery life in portable touch interfaces. |
| USB Device Stack Support | Includes certified USB HID and CDC class drivers in PSoC™ Creator IDE - reduces firmware development time by ~3 weeks vs bare-metal implementation. |
Applications
| Industrial HMI Panel | Medical Patient Monitor |
|---|---|
Use Scenario: Touchscreen overlay on sealed front panel of PLC operator terminal requiring ESD-hardened, glove-compatible input. IC Role / Device Role / Timing Role: Primary MCU executing CapSense™ scan, USB HID report generation, and real-time status LED control with <10 ms response latency. Use Value: Integrated CapSense™ eliminates external touch controller IC; USB device mode enables direct connection to host PC for configuration and diagnostics without additional USB-to-serial bridge. | Use Scenario: Bedside vital sign display with capacitive slider for volume adjustment and proximity wake-up to conserve power. IC Role / Device Role / Timing Role: System-on-chip managing sensor data aggregation, local UI rendering, and USB CDC interface for clinical data export. Use Value: Hardware TRNG and AES enable HIPAA-compliant encrypted data logging; deep-sleep current <1.5 µA extends battery runtime beyond 72 hours during standby. |
| Smart Home Thermostat | Automotive Cabin Control |
Use Scenario: Wall-mounted HVAC controller with ambient light adaptive backlight and multi-finger gesture recognition. IC Role / Device Role / Timing Role: Central controller performing ambient light sensing (via IDAC + photodiode), CapSense™ gesture decoding, and Zigbee/Thread co-processor interface via UART. Use Value: Programmable analog blocks condition photodiode signal without external op-amp; mutual-capacitive scanning rejects false triggers from condensation or dust. | Use Scenario: Center console climate control module with haptic feedback and CAN bus integration for vehicle network communication. IC Role / Device Role / Timing Role: Dedicated UI processor offloading touch processing from main body controller; communicates via isolated CAN transceiver connected to P0[6]/P0[7]. Use Value: Dual-supply architecture (VDDA/VDDD) isolates analog CapSense™ noise from digital CAN signaling; flash protection prevents unauthorized firmware modification. |
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 |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same core and memory, but 48-pin QFN, no USB PHY, reduced CapSense™ channels (32 self-cap) | Lacks USB connectivity; suitable only for UART/I²C-based HMI where host-side USB bridge is acceptable | Select when board space is constrained and USB is not required - saves ~$0.35/unit at 10k volume |
| STM32F072CBT6 | Arm® Cortex®-M0, 128 KB flash, 16 KB SRAM, USB 2.0 device, but no integrated CapSense™ or programmable analog/digital blocks | Requires external touch controller and op-amp circuitry for comparable analog functionality | Select when leveraging existing STM32 ecosystem tools and prefer vendor-agnostic HAL libraries over PSoC™ Creator's component-based design flow |
Compared with CY8C4248FLI-BL583T, CY8C4247LQI-BL483 trades USB and CapSense™ scalability for smaller footprint and cost, while STM32F072CBT6 offers broader toolchain support but increases BOM count and analog design effort for touch applications.

FAQ
Does CY8C4248FLI-BL583T support Bluetooth Low Energy?
No, this device does not integrate a Bluetooth radio or baseband. It lacks the RF transceiver, matching network, and antenna interface required for BLE. However, it can interface with external BLE modules (e.g., CYBLE-416045-02) via UART or SPI, and its hardware AES engine accelerates BLE pairing and encryption operations.
What debug interface does CY8C4248FLI-BL583T use?
It uses ARM Serial Wire Debug (SWD) over two dedicated pins (SWDIO and SWCLK), compatible with standard J-Link, CMSIS-DAP, and MiniProg4 debug probes. The device supports full run-control debugging, flash programming, and real-time variable monitoring without requiring additional debug headers or trace pins.
Can the CapSense™ subsystem operate during deep-sleep mode?
Yes, CapSense™ can perform low-power scanning in deep-sleep mode using the dedicated CapSense™ interrupt controller and hardware sequencer. It consumes 1.8 µA typical while scanning up to 8 buttons at 10 Hz, with automatic wake-up triggered by touch event to resume full CPU operation.
Is there a qualified automotive-grade version of this part?
No, CY8C4248FLI-BL583T is rated for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive cabin applications, Infineon recommends the PSOC™ Automotive 4 series (e.g., CY8C4045LQI-S412), which includes AEC-Q100 Grade 2 qualification, extended temperature support (–40°C to +105°C), and enhanced ESD robustness (±15 kV HBM).
