Product details
Overview
CY8C4247LQQ-BL483 from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller integrating AIROC™ Bluetooth® Low Energy (BLE) 4.2 radio, 256 KB flash, 32 KB SRAM, and programmable analog/digital blocks. It delivers -89 dBm RX sensitivity, +3 dBm TX output, and operates in Deep Sleep at 1.5 µA with WCO active-enabling battery-powered BLE sensor nodes, smart wearables, and IoT edge devices.
For engineers reviewing the CY8C4247LQQ-BL483 datasheet, CY8C4247LQQ-BL483 pinout, CY8C4247LQQ-BL483 application, or CY8C4247LQQ-BL483 equivalent, key selection criteria include integrated BLE subsystem coexistence with SAR ADC (1-Msps, 12-bit), opamp-based CAPSENSE™ support, TCPWM timing precision, and QFN-56 package compatibility for compact PCB layouts.
Technical Context
This MCU implements a tightly coupled BLE subsystem (BLESS) with dedicated digital PHY and link-layer engine supporting concurrent master/slave roles. Its RF transceiver drives a 50-Ω antenna directly and provides 1-dB-resolution RSSI for proximity-aware applications.
The analog subsystem includes four opamps with Comparator mode and ADC input buffering, plus a 12-bit SAR ADC with channel sequencer and signal averaging-enabling high-SNR capacitive sensing and sensor signal conditioning without external components.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52833 | 64 MHz Arm® Cortex®-M4F; 512 KB flash; no integrated opamps or CAPSENSE™ analog front-end | Requires external signal conditioning for analog sensors; better suited for compute-intensive BLE mesh or audio streaming | Select when floating-point math or larger code footprint is needed; not optimal for capacitive touch or analog sensor integration |
| Texas Instruments CC2642R | 48 MHz Arm® Cortex®-M4F; 352 KB flash; integrated RF but no programmable analog blocks or UDBs | Lacks reconfigurable analog/digital logic; relies on fixed-function peripherals and external components for sensor signal chain | Prefer for long-range BLE or multi-protocol (BLE + IEEE 802.15.4) designs where analog programmability is secondary |
Compared with nRF52833 and CC2642R, CY8C4247LQQ-BL483 uniquely integrates BLE radio, programmable analog (opamps, ADC, CAPSENSE™), and digital logic (UDBs) on a single die-reducing BOM count and enabling field-tunable sensor interfaces without external ICs.

FAQ
Does CY8C4247LQQ-BL483 support Over-The-Air (OTA) firmware updates?
Yes. The device supports OTA DFU via BLE using the PSoC™ Creator BLE Component and AN91267/AN97060 application notes. Firmware images are validated using CRC-32 before execution, and dual-bank flash allows safe rollback on update failure.
What crystal configurations are required for full BLE and Deep Sleep functionality?
A 24 MHz crystal is required for main system clock and BLE RF timing; a separate 32.768 kHz watch crystal (WCO) is mandatory for Deep Sleep mode and RTC operation. Both must meet load capacitance and ESR specs per AN95089.
Can all 36 GPIOs be used simultaneously for CAPSENSE™ and serial communication?
No. While any GPIO can be assigned to CAPSENSE™ or SCB functions, resource contention occurs: CAPSENSE™ requires dedicated analog routing paths, and SCBs consume shared digital interconnect. Simultaneous full utilization requires careful pin assignment and UDB-assisted multiplexing per PSoC™ Creator constraints.
Is the AIROC™ BLE subsystem certified for regulatory compliance?
Yes. The integrated AIROC™ BLE radio meets FCC Part 15.247, CE RED, and IC RSS-247 requirements. Pre-certified module variants (e.g., CY8CKIT-142) carry full regional certifications; standalone CY8C4247LQQ-BL483 requires end-product level testing with validated antenna layout per AN91445.
