The IS1678 is a fully‐certified Bluetooth^® (BR/EDR/LE) IC for designers who want to easily add dual mode Bluetooth wireless capability to their products. Delivering local connectivity for the Internet of Things (IoT), the IS1678 IC bridges your product to Smart Phones and Tablets for convenient data transfer, control and access to cloud applications.
This Bluetooth SIG certified module provides a complete wireless solution with Bluetooth stack onboard, integrated antenna, and worldwide radio certifications in a compact surface mount package, 6 x 6 mm. It supports GAP, SDP, SPP, and GATT profiles. Data is transferred over the Bluetooth link by sending/receiving data via transparent UART mode, making it easy to integrate with any processor or microcontroller with a UART interface. Configuration is made easy using a Windows^® based GUI or directly via UART by a MCU.

The IS1678 SoC is available in ROM-based (IS1678S) and Flash-based (IS1678SM) variants.
