Product details
Overview
CY8C4247FNQ-BL483T 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 embedded wireless control for battery-powered IoT endpoints with integrated capacitive sensing, LCD drive, and low-power operation down to 150 nA in Hibernate mode.
For engineers reviewing the CY8C4247FNQ-BL483T datasheet, CY8C4247FNQ-BL483T pinout, CY8C4247FNQ-BL483T application, or CY8C4247FNQ-BL483T equivalent, key selection criteria include BLE 4.2 compliance, 7 mm × 7 mm 56-pin QFN package, -89 dBm RX sensitivity, 1.5 µA Deep Sleep current with WCO, and hardware-accelerated CAPSENSE™ with SmartSense tuning.
Technical Context
This MCU implements a dual-subsystem 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. The BLESS supports concurrent master/slave roles and integrates RSSI measurement with 1-dB resolution.
Analog resources include four opamps supporting comparator mode and ADC buffering, a 12-bit 1-Msps SAR ADC with channel sequencer and averaging, and two IDACs usable for CAPSENSE™. Digital flexibility comes from four UDBs-each with eight macrocells-and two reconfigurable SCBs supporting I²C/SPI/UART on-the-fly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLE MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52840-QIAA | 64 MHz Arm® Cortex®-M4F, 1 MB flash, no integrated analog peripherals (ADC/opamp), higher TX power (+8 dBm) | Lacks hardware CAPSENSE™, LCD drive, and programmable analog; requires external components for sensor interface | Preferred when floating-point math, larger code space, or higher RF range is required-but adds BOM cost and layout complexity |
| Texas Instruments CC2642R1F | 48 MHz Arm® Cortex®-M4F, 352 KB flash, integrated 12-bit ADC (no opamps), lower Deep Sleep current (1.1 µA) | No programmable digital logic (UDBs), no LCD drive, limited GPIO reconfiguration flexibility | Better for pure BLE+sensor apps needing ultra-low sleep current and TI's SimpleLink SDK-but lacks PSoC™'s analog/digital co-design capability |
Compared with nRF52840-QIAA and CC2642R1F, CY8C4247FNQ-BL483T uniquely integrates programmable analog (opamps, IDACs, CSD), digital logic (UDBs), and LCD drive in a single chip-reducing component count and enabling field-tunable sensor interfaces without firmware changes.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0 core in CY8C4247FNQ-BL483T?
The Arm® Cortex®-M0 core operates at up to 48 MHz, supported by a flash read accelerator that eliminates wait states during instruction fetch. This frequency is achievable across the full industrial temperature range (-40°C to +85°C) when supplied with VDDD ≥ 2.7 V and proper clock configuration using IMO or ECO sources.
Does CY8C4247FNQ-BL483T support over-the-air (OTA) firmware updates?
Yes, OTA firmware updates are fully supported via the BLE stack using the standard BLE DFU (Device Firmware Upgrade) service. Infineon provides the BLE_OTA component in PSoC™ Creator and reference code in AN91267 and AN97060, enabling secure, signed image updates without external programmer access.
Can the integrated opamps be used during Deep Sleep mode?
Yes, all four opamps can remain powered and operational in Deep Sleep mode (1.5 µA total system current with WCO active). They support comparator mode and ADC input buffering, enabling wake-on-analog-threshold functionality without exiting Deep Sleep-critical for battery lifetime in always-on sensor applications.
What antenna interface topology does CY8C4247FNQ-BL483T require?
CY8C4247FNQ-BL483T provides a single-ended 50 Ω ANT pin requiring impedance-matched RF layout. A π-network (two capacitors + one inductor) or balun-based matching circuit is mandatory to interface with PCB or chip antennas. AN91445 specifies layout rules including ground clearance, keep-out zones, and trace width tolerances to maintain -89 dBm RX sensitivity.
