Product details
Overview
CY8C4247LQI-BL463 from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller integrating AIROC™ Bluetooth® LE 4.2 radio, 48 MHz CPU, 256 KB flash, 32 KB SRAM, and programmable analog/digital blocks. It delivers BLE connectivity with –89 dBm RX sensitivity and +3 dBm TX output in a 7 mm × 7 mm 56-pin QFN package, targeting compact wireless sensor nodes and battery-powered IoT endpoints.
For engineers reviewing the CY8C4247LQI-BL463 datasheet, CY8C4247LQI-BL463 pinout, CY8C4247LQI-BL463 application, or CY8C4247LQI-BL463 equivalent, key selection criteria include integrated BLE subsystem power efficiency (15.6 mA TX @ 0 dBm), Deep Sleep current (1.5 µA with WCO), SAR ADC performance (12-bit, 1-Msps), and GPIO flexibility (36 pins supporting CAPSENSE™, LCD, analog, or digital functions).
Technical Context
The device implements a dual-domain architecture: an Arm® Cortex®-M0 core with DMA and flash accelerator coexists with a dedicated Bluetooth® LE subsystem (BLESS) containing digital PHY, link-layer engine, and RF transceiver. Clocking includes IMO (internal main oscillator), ILO (low-power internal), ECO (external crystal), and WCO (watch crystal) sources for precise timing across operating modes.
Analog resources comprise four opamps with comparator mode and ADC input buffering, a 12-bit SAR ADC with channel sequencer and signal averaging, two IDACs, and two low-power comparators-all operable in Deep Sleep. Digital reconfigurability is enabled via four Universal Digital Blocks (UDBs), each with eight macrocells and data path, plus fixed-function TCPWM and SCB peripherals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLE MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52833 DK | 64 MHz Arm® Cortex®-M4F, 512 KB flash, no integrated analog peripherals (ADC/opamp), requires external components for sensor interface | Better computational throughput but higher BOM cost and layout complexity for analog-sensing designs | Prefer when floating-point math or audio processing dominates; avoid when CAPSENSE™ or opamp-based signal chain is required |
| Texas Instruments CC2642R | 48 MHz Arm® Cortex®-M4F, 352 KB flash, integrated 12-bit ADC (1 Msps), but only two opamps and no CAPSENSE™ engine | Limited capacitive sensing capability; lacks SmartSense auto-tuning and sigma-delta architecture | Select for high-precision ADC-only applications; not suitable for robust touch interfaces in humid environments |
Compared with nRF52833 DK and CC2642R, CY8C4247LQI-BL463 uniquely integrates programmable analog (four opamps + CSD), digital logic (UDBs), and BLE in one die - reducing component count and enabling field-reconfigurable sensor interfaces without redesign.

FAQ
What development tools are supported for CY8C4247LQI-BL463?
Infineon's PSoC™ Creator IDE (Windows-only, free) provides schematic-based design entry, automatic analog/digital routing, and pre-verified API components. Post-design, Arm®-compliant toolchains (GCC, Keil, IAR) support firmware compilation and debugging via SWD interface. The MiniProg3 programmer/debugger is required for flash programming and JTAG/SWD access.
Does CY8C4247LQI-BL463 support Bluetooth® LE 5.0 or later?
No - the device implements Bluetooth® LE 4.2 as specified in its BLESS subsystem. It does not support LE 5.0 features such as Long Range (Coded PHY), Higher Throughput (2 Mbps PHY), or Advertising Extensions. Firmware updates cannot extend PHY capabilities beyond hardware implementation.
Can the internal opamps drive external loads directly?
Yes - each opamp supports high-drive external mode (up to 25 mA sink/source) and can directly drive resistive or capacitive loads including LCD segments and small piezoelectric elements. Internal high-bandwidth mode is optimized for ADC buffering and comparator feedback paths.
Is the 7 mm × 7 mm QFN package RoHS and REACH compliant?
Yes - CY8C4247LQI-BL463 conforms to EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Material declarations and test reports are available through Infineon's Product Change Notification (PCN) portal and authorized distributor portals (e.g., Digi-Key, Mouser).
