IS1677

The IS1677 Bluetooth IC is designed for both Bluetooth SPP and Bluetooth Low Energy applications.  The IS1677 is a 40 pin QFN single-chip Bluetooth IC and is available in the 2.4GHz ISM band Class 2 Radio, compatible with Bluetooth Core Specification Version 3.0/ 4.0 + EDR dual mode.

The IS1677 single chip solution combines transceiver and baseband function to decrease the external components.  In addition, to minimize the external components required for portable devices, a battery voltage sensor, an internal boost, a switching regulator and LDOs are integrated to reduce BOM cost for various Bluetooth applications.  The optimized power design minimizes power consumption greatly extending battery life.
