Product details
Overview
CY8C4248LQI-BL563 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, capacitive sensing (CSD), LCD drive, and TCPWM for embedded wireless sensor nodes, smart home peripherals, and battery-powered IoT endpoints.
For engineers reviewing the CY8C4248LQI-BL563 datasheet, CY8C4248LQI-BL563 pinout, CY8C4248LQI-BL563 application, or CY8C4248LQI-BL563 equivalent, key selection criteria include integrated BLE subsystem performance (–89 dBm RX sensitivity, +3 dBm TX power), low-power Deep Sleep mode (1.5 µA with WCO), 36 GPIOs with CAPSENSE™/LCD/analog support, and QFN-56 package compatibility.
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 analog subsystem includes four opamps with comparator mode and ADC input buffering, plus a 12-bit, 1-Msps SAR ADC with channel sequencer and signal averaging.
The digital architecture features four Universal Digital Blocks (UDBs), each with eight macrocells and data path, enabling custom logic synthesis. Two reconfigurable Serial Communication Blocks (SCBs) support runtime-switchable I²C/SPI/UART, while four 16-bit TCPWM blocks provide center-aligned PWM and comparator-triggered kill signals for motor control safety.

FAQ
What development tools are supported for CY8C4248LQI-BL563?
Infineon's free PSoC™ Creator IDE provides schematic-based hardware design, pre-verified peripheral components, and automatic routing for analog/digital blocks. Firmware development uses GCC-based toolchain with CMSIS support. Debugging is enabled via SWD using MiniProg3 or KitProg2 programmers, and the CY8CKIT-042-BLE-A Pioneer Kit offers full evaluation capability with Arduino-compatible headers and onboard BLE antenna.
Does CY8C4248LQI-BL563 support over-the-air (OTA) firmware updates?
Yes, CY8C4248LQI-BL563 supports secure OTA DFU using the BLE stack and internal bootloader. Application notes AN91267 and AN97060 detail implementation with dual-bank flash layout, CRC validation, and rollback protection. The 256 KB flash allows simultaneous storage of active and update images, ensuring zero-downtime field upgrades without external memory.
How does the CAPSENSE™ subsystem handle water or condensation interference?
The CSD block achieves >5:1 SNR and liquid tolerance through shield-driven scanning, frequency hopping, and SmartSense auto-tuning. It dynamically adjusts scan parameters (IDAC current, resolution, averaging) to maintain button detection under wet conditions. Hardware-accelerated baseline tracking and noise filtering eliminate false triggers without CPU overhead, validated per IEC 61000-4-3 radiated immunity testing.
Can the BLE subsystem operate independently while the CPU is in Deep Sleep?
Yes, the BLESS subsystem retains full autonomous operation in Deep Sleep mode, including advertising, scanning, and connection handling. It wakes the CPU only on specific events (e.g., GATT write, connection request, or RSSI threshold breach), maintaining 1.5 µA system current. This enables ultra-low-power beaconing or sensor polling without continuous CPU activity.
