CYBT-273063-02 概述
A Bluetooth module is an RF transceiver subsystem that integrates a radio, baseband, antenna interface, and a programmable host MCU into a single pre-certified unit. Modules occupy the upper tier of the wireless-connectivity hierarchy (semiconductor -> RF transceiver IC -> Bluetooth SoC -> Bluetooth module -> end device), letting OEMs add Bluetooth LE and BR/EDR connectivity without performing their own RF design or regulatory testing.
Key features include Bluetooth 5.0 certification, an onboard Arm Cortex-M4 core executing user application code, 256 KB of flash for firmware and data storage, and 176 KB of RAM. The U.FL antenna connector supports a standard 2.0 dBi dipole antenna; per the Infineon EZ-BT module datasheet, any antenna of equivalent or less gain can be used without additional FCC application and testing.
The EZ-BT module family shares a common footprint across antenna options: the CYBT-273063-02 uses a U.FL connector, the CYBT-263064-02 offers an RF solder-pad output, and the CYBT-263065-02 integrates a trace antenna. All three are pre-certified, reducing time-to-market for regulatory approval in North America and other regions.
Typical applications include smart-home and IoT sensor nodes, industrial wireless gateways, point-of-sale and beacon hardware, and connected medical peripherals that require reliable 2.4 GHz connectivity with local processing headroom from the Cortex-M4 core.
Design consideration: because the antenna is external, place the U.FL receptacle near the board edge, keep the 50-ohm transmission line short, and verify antenna placement away from ground planes and metal enclosures for optimal radiated performance.

典型应用
CYBT-273063-02 适用于 6 应用s: Smart Home and IoT Sensor Nodes, Industrial Wireless Gateways, Beacons and Proximity Marketing Hardware, Connected Medical Peripherals, Point-of-Sale and Mobile Accessories, Prototype and Development Platforms.
Smart Home and IoT Sensor Nodes
The CYBT-273063-02 fits battery-conscious smart-home products because its Bluetooth 5.0 radio supports BLE low-energy modes while the onboard Arm Cortex-M4 with 176 KB RAM handles local sensor processing without a second MCU. The 256 KB flash stores application firmware and OTA update images, an important requirement for deployed IoT fleets. Used as the primary connectivity controller, the module attaches to sensors over I2C/SPI and reports through BLE GATT services. The external U.FL antenna lets designers optimize radiated performance inside plastic enclosures; any antenna of 2.0 dBi or less gain per the Infineon datasheet needs no additional FCC testing, simplifying certification of the end device.
推荐
Industrial Wireless Gateways
In industrial gateways, the CYBT-273063-02 serves as a pre-certified 2.4 GHz bridge between BLE field sensors and a higher-level host processor or Ethernet controller. The Cortex-M4 core with 256 KB flash runs protocol translation and buffering firmware, while 176 KB RAM accommodates packet queues typical of multi-node deployments. Bluetooth 5.0 BR/EDR plus BLE support allows both legacy-adjacent and low-energy device populations on one module. The U.FL connector allows routing to a panel-mounted external antenna, which is often essential in metal control cabinets where onboard antennas fail. Because the module is pre-certified, system integrators avoid the cost and schedule of module-level RF regulatory testing.
推荐
Beacons and Proximity Marketing Hardware
BLE beacon hardware is a natural fit for the CYBT-273063-02: the module's Bluetooth 5.0 radio transmits advertising packets while its Arm Cortex-M4 and 256 KB flash can host beacon management, scheduling, and configuration firmware locally. The 176 KB RAM supports Eddystone/iBeacon frame buffering and secure configuration storage. Power consumption in BLE advertising mode is the dominant design factor for battery-operated beacons; exact TX current figures are available in the Infineon EZ-BT datasheet. The U.FL antenna output permits either internal pigtails or external antennas when deployment sites demand extended range beyond what a trace antenna can achieve in compact enclosures.
推荐
Connected Medical Peripherals
Wearable and desktop medical peripherals benefit from the CYBT-273063-02's combination of a pre-certified Bluetooth 5.0 radio and local Cortex-M4 processing headroom. Vital-sign data from analog front ends can be filtered and packetized on the module's 256 KB flash and 176 KB RAM before BLE transmission, reducing host dependency and improving latency. The external U.FL antenna helps maintain reliable link margin in clinical environments with metal equipment. Infineon's module-level certification simplifies the wireless portion of the device's regulatory file, though designers must still complete end-product EMC and patient-safety validation according to their applicable medical-device standards.
推荐
Point-of-Sale and Mobile Accessories
The CYBT-273063-02 suits point-of-sale terminals, barcode scanners, and receipt printers that need cable-free links to tablets and phones. Bluetooth 5.0 BR/EDR support covers classic SPP-style data links while BLE handles low-rate status and configuration traffic. The Cortex-M4 with 256 KB flash can run device firmware, pairing management, and firmware-update loaders directly on the module, shrinking total BOM count. The U.FL external antenna allows optimal antenna placement in handheld plastic housings for consistent range. Because the module ships pre-certified, accessory manufacturers can iterate hardware quickly without repeating module-level Bluetooth and FCC qualification for each product revision.
推荐
Prototype and Development Platforms
For wireless product development, the CYBT-273063-02 functions as the radio subsystem on evaluation and prototyping boards. Its pre-certified status lets engineering teams test firmware and RF behavior immediately without waivers or shielded-lab module certification. The Cortex-M4 plus 256 KB flash / 176 KB RAM configuration supports the full Bluetooth 5.0 protocol stack with room for user application code, matching the architecture of the final production device. The U.FL connector accepts standard pigtail-to-SMA cables, allowing direct connection of spectrum analyzers and reference antennas during RF characterization - a significant convenience over trace-antenna modules during design bring-up.

设计说明
The CYBT-273063-02 connects to its antenna through a U.FL receptacle, so RF performance depends heavily on the pigtail and antenna chosen. Use a 50-ohm U.FL-to-SMA or U.FL-to-dipole assembly and route it away from switching regulators and high-speed digital traces. Per the Infineon EZ-BT datasheet, the module family is designed to work with a standard 2.0 dBi dipole antenna, and any antenna of equivalent or less gain can be used without additional FCC application and testing - using higher-gain antennas may void that simplified certification path.
Place the module at the board edge with the U.FL receptacle facing outward, and keep the antenna cable away from ground planes and metal housings. Follow the EZ-BT datasheet recommended land pattern and keep-out zone under the module; most EZ-BT implementations reserve the area beneath the module, so avoid routing signals there. Provide clean 3.3 V-class supply decoupling at the module supply pins with local ceramic capacitors, and star-route the ground connection to minimize radiated-harmonic issues during FCC pre-scan.
Do not assume the whole CYBT-2X30XX-02 family is interchangeable without checking antenna strategy: the -02 suffix here means U.FL, while CYBT-263064-02 exposes an RF solder pad and CYBT-263065-02 has a fixed trace antenna. Swapping variants on the same footprint changes radiated performance and certification scope. Also confirm power-supply sequencing and brownout behavior, since the Cortex-M4 boots application code from the 256 KB flash at power-up; unstable supplies can corrupt in-field OTA updates stored in flash.
