Product details
Overview
CY8C4248LQI-BL593 from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller integrating AIROC™ Bluetooth® LE 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 at 48 MHz for embedded wireless sensor nodes, BLE beacons, and human interface devices requiring integrated RF and capacitive sensing.
For engineers reviewing the CY8C4248LQI-BL593 datasheet, CY8C4248LQI-BL593 pinout, CY8C4248LQI-BL593 application, or CY8C4248LQI-BL593 equivalent, key selection criteria include Bluetooth® LE 4.2 compliance, 1.5 µA Deep Sleep current with WCO, 12-bit 1-Msps SAR ADC, CAPSENSE™ sigma-delta architecture, and 7 mm × 7 mm 56-pin QFN package compatibility.
Technical Context
This MCU implements a dual-domain architecture: the Arm® Cortex®-M0 core manages firmware execution and protocol stack, while the dedicated BLESS (Bluetooth® Low Energy Subsystem) handles link-layer operations including master/slave mode arbitration, packet encryption, and RF state management. The BLESS includes digital PHY, RSSI engine with 1-dB resolution, and hardware-accelerated AES-128.
Analog subsystem integration includes four opamps supporting comparator mode and ADC input buffering, two low-power comparators active in Deep Sleep, and a 12-bit SAR ADC with channel sequencer and signal averaging-enabling simultaneous touch sensing and sensor signal acquisition without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth® LE microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52840-QIAA | ARM Cortex-M4F @ 64 MHz; 1 MB flash; no integrated CAPSENSE™ or programmable analog | Higher compute throughput for complex BLE mesh or audio processing; lacks hardware touch engine | Select when floating-point math or multi-protocol (Thread/Zigbee) is required; add external touch IC if needed |
| Texas Instruments CC2642R1F | ARM Cortex-M4F @ 48 MHz; 352 KB flash; integrated RF but no programmable analog/digital fabric | Better RF performance (-96 dBm RX); no UDBs or opamp-based sensor front-end | Select for long-range BLE or concurrent BLE + IEEE 802.15.4; use external ADC/opamp for analog signal conditioning |
Compared with nRF52840-QIAA and CC2642R1F, CY8C4248LQI-BL593 uniquely integrates programmable analog (opamps, IDACs, CSD), digital logic (UDBs), and BLE in one die-reducing component count and enabling field-tunable mixed-signal behavior without external components.

FAQ
What is the maximum operating temperature for CY8C4248LQI-BL593?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal derating begins above 70 °C ambient when operating at 48 MHz with full peripheral activation; junction temperature must remain below 125 °C per absolute maximum ratings in datasheet Section 5.1.
Does CY8C4248LQI-BL593 require an external crystal for BLE operation?
Yes-BLE timing compliance requires a 24 MHz external crystal (ECO) connected to XTAL_IN/XTAL_OUT pins. The internal IMO is insufficient for BLE radio accuracy. A 32.768 kHz watch crystal (WCO) is optional but required for sub-µA Deep Sleep timing.
Can the CAPSENSE™ block operate independently of the CPU?
Yes-the CAPSENSE™ CSD engine runs autonomously using hardware sequencers and SmartSense tuning. It can scan up to 32 sensors while the CPU remains in Deep Sleep, waking only upon threshold-triggered interrupt or completion event.
How many BLE connections does CY8C4248LQI-BL593 support simultaneously?
The BLESS hardware supports up to 8 concurrent BLE connections in slave role and 1 master connection. Connection count depends on memory allocation: default BLE stack uses ~48 KB flash and ~12 KB SRAM, leaving space for application code and additional profiles.
