Product details
Overview
CY8C4248FNI-BL593T 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 in Deep Sleep at 1.5 µA with WCO active-enabling battery-powered BLE sensor nodes and human interface devices.
For engineers reviewing the CY8C4248FNI-BL593T datasheet, CY8C4248FNI-BL593T pinout, CY8C4248FNI-BL593T application, or CY8C4248FNI-BL593T equivalent, key selection criteria include integrated BLE subsystem timing, SAR ADC resolution and sampling rate, opamp low-power operation in Deep Sleep, GPIO count and OVT capability, and PSoC™ Creator compatibility for mixed-signal configuration.
Technical Context
This MCU implements a dual-domain architecture: the Arm® Cortex®-M0 core handles application firmware and BLE stack execution, while the BLESS (Bluetooth® Low Energy Subsystem) handles RF PHY, link-layer state machine, and packet processing independently. The BLESS supports both master and slave roles with hardware-accelerated encryption and RSSI reporting at 1-dB resolution.
Analog subsystem includes four opamps supporting comparator mode and ADC input buffering, a 12-bit 1-Msps SAR ADC with channel sequencer and signal averaging, and two IDACs for capacitive sensing. Digital flexibility comes from four UDBs (Universal Digital Blocks), each with eight macrocells and data path, enabling custom logic and state machines without FPGA-level complexity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply and DMA support for real-time control and BLE stack offload |
| Memory | 256 KB flash (with read accelerator) and 32 KB SRAM-sufficient for BLE GATT server, sensor fusion, and OTA DFU |
| BLE Radio | Bluetooth® LE 4.2 compliant; -89 dBm RX sensitivity and +3 dBm TX output enable 30+ m range in typical PCB antenna layouts |
| ADC | 12-bit SAR ADC @ 1 Msps with differential/single-ended modes and hardware channel sequencer-supports multi-sensor acquisition without CPU intervention |
| Power Modes | Deep Sleep: 1.5 µA (WCO active); Hibernate: 150 nA (RAM retention); Stop: 60 nA-enables >1-year coin-cell operation in periodic wake-up sensing |
| GPIO | Up to 36 programmable pins including 2 overvoltage-tolerant (OVT) inputs-supports direct connection to industrial I/O or automotive sensors without level-shifting |
| CAPSENSE™ | Capacitive sigma-delta (CSD) engine with >5:1 SNR and SmartSense auto-tuning-enables robust touch buttons/sliders under water or glove use |
Pinout & Package
The CY8C4248FNI-BL593T is housed in a 7 mm × 7 mm, 56-pin QFN package with exposed thermal pad (EP). Pin assignments are defined per the Infineon CY8C42xx-BL datasheet Rev. *B, Section 2 "Pinouts", and include dedicated RFIO, VDDRF, and ANT connections for optimal 2.4-GHz matching network integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Digital supply rail | 1.71–5.5 V input; powers CPU, digital peripherals, and GPIO; requires local 100-nF decoupling |
| VDDA | Analog supply rail | Separate 1.71–5.5 V input for ADC, opamps, and comparators; improves noise immunity for precision sensing |
| RFIO | RF transceiver I/O | Differential 50-Ω RF port; connects directly to matching network and PCB antenna per AN91445 layout guidelines |
| VDDRF | RF supply rail | 1.71–3.6 V dedicated supply for BLESS; must be filtered separately to minimize RF coupling into digital domains |
| XRES | Active-low reset input | Asynchronous reset with internal pull-up; accepts 1.2–5.5 V logic; debounced externally for ESD robustness |
| P0[0]–P0[7] | General-purpose I/O | Programmable drive strength, slew rate, and analog/digital/CAPSENSE™/LCD function per pin-no fixed peripheral mapping |

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, -96 dBm RX sensitivity, no integrated opamps or CAPSENSE™ | Higher compute throughput but requires external analog front-end for sensor conditioning | Select when floating-point math or higher BLE throughput (>1 Mbps) is critical; not suitable for analog-integrated designs |
| Texas Instruments CC2642R1 | 48 MHz Arm® Cortex®-M4F, 352 KB flash, -103 dBm RX, integrated 12-bit ADC (200 ksps), no programmable analog blocks | Better RF performance and larger memory, but lacks opamp/comparator flexibility and CAPSENSE™ engine | Prefer for long-range beaconing or high-memory OTA applications where analog configurability is secondary |
Compared with nRF52833-DK and CC2642R1, CY8C4248FNI-BL593T uniquely combines BLE 4.2 radio, programmable analog (opamps + ADC + IDACs), and CAPSENSE™ in one die-reducing BOM count by up to 7 components in touch + sensing + connectivity designs.

FAQ
What development tools are supported for CY8C4248FNI-BL593T?
Infineon provides PSoC™ Creator IDE (free Windows-based tool) with schematic-driven design, pre-verified components, and automatic analog/digital routing. It supports C firmware development, BLE stack configuration, and hardware co-simulation. Industry-standard Arm® tools-including Keil MDK, IAR Embedded Workbench, and GCC-based toolchains-are also compatible via PSoC™ 4 SDK and CMSIS layer.
Does CY8C4248FNI-BL593T require an external crystal for BLE operation?
Yes-BLE RF timing requires a 24 MHz or 32 MHz external crystal connected to the ECO pins. The internal IMO is insufficient for BLE radio accuracy. A separate 32.768 kHz watch crystal (WCO) is recommended for Deep Sleep timing but optional if RTC functionality is unused. Crystal selection and PCB layout must follow AN95089 guidelines.
Can all 36 GPIOs be used simultaneously for CAPSENSE™ and analog functions?
No-while any GPIO can be assigned to CAPSENSE™ or analog roles, resource contention exists. The CSD engine uses dedicated analog routing paths and shares opamp/ADC resources. Simultaneous full-capacity CAPSENSE™ (e.g., 20+ sensors) and high-speed ADC sampling (≥500 ksps) may require time-multiplexing or reduced channel count per mode, as confirmed in the TRM Section 1.4.1 and 1.8.2.
Is the BLE subsystem certified for regulatory compliance?
The CY8C4248FNI-BL593T device itself is FCC/IC/CE/RED certified as a module-level solution when used with the reference PCB antenna and matching network per CY8CKIT-142 layout. Final system certification remains the responsibility of the end-product designer, but Infineon provides test reports, antenna design files (AN91445), and pre-certified module variants to accelerate approval.
