The BDE-LE2340R5KP is a Bluetooth 2.4G wireless module that integrates an Arm® Cortex®-M0+ MCU, which supports Bluetooth ® 5.3 Low Energy, ZigBee, SimpleLink™ TI 15.4-stack, Proprietary systems. This device is optimized for low-power wireless communication with on-chip dual image Over the Air Download (OAD) support in Building automation (wireless sensors, lighting control, beacons), asset tracking, medical, retail EPOS (electronic point of sale), ESL (electronic shelf label), and Personal electronics (toys, HID, stylus pens) markets.

The BDE-LE2340R5KP supports operation in the 2360 to 2510-MHz frequency band. It can support +8 dBm output power in 2.4GHz band, and a receive sensitivity of -102 dBm for 125-kbps Bluetooth® Low Energy Coded PHY. The BDE-LE2340R5KP has an ultra-low standby current less than 0.71 μA with RTC operational and full RAM retention that enables significant battery life extension especially for applications with longer sleep intervals. The module supports for Bluetooth® 5 features: High Speed Mode (2 Mbps PHY), Long Range (LE Coded 125 kbps and 500 kbps PHYs), Privacy 1.2.1 and Channel Selection Algorithm #2, as well as backwards compatibility and support for key features from the Bluetooth® 4.2 and earlier Low Energy specifications.

The BDE-LE2340R5KP highly integrates radio, stack, profile and applications in a SoC, without the need of using an external MCU. The module also offers flexible hardware interfaces for the sensor application. It enables ultra-low power connectivity and data transfer for the applications that are sensitive to power consumption, size and cost.
