WSDT-752B

ARM Cortex M3 + Bluetooth Low Energy Module

WSDT-752B is a low-cost and low-power consumption module which has of the BLE functionalities. The highly integrated WSDT-752B with RF front end BLE module makes the possibilities of Bluetooth Low Energy HID and other applications.

The WSDT-752B is Very low active and low power mode current consumption as well as fast mode transitions provide excellent battery lifetime and allows operation on small coin cell batteries and in energy harvesting applications.

Integrated a powerful 32-bit Cortex M3 running at 48 MHz has more than 30% more processing power per MHz than Cortex M0 based systems and significantly more than 8 and 16-bit processors.

The Bluetooth Low Energy Controller is embedded into ROM and are partly running on a separate ARM Cortex M0 dedicated for radio purpose. This improves overall system performance and power consumption as well as frees up FLASH memory for the application.
