This document describes key hardware aspects of the Laird BT860 Bluetooth HCI module. This document is
intended to assist device manufacturers and related parties with the integration of this module into their host
devices. Data in this document are drawn from a number of sources including data sheets for the CYW20704A2.
Because the BT860 is currently in development stage, this document is preliminary and the information in this
document is subject to change. Please contact Laird Technologies or visit the Laird website at

2 O PERATIONAL D ESCRIPTION
The BT86x series of UART HCI modules leverage the Cypress CYW20704 A2 chipset to provide exceptionally low
power consumption with outstanding range for OEMs needing both Classic Bluetooth and Bluetooth Low Energy
support. The Bluetooth v4.2 core specification shortens your development time and provides enhanced
throughput, security and privacy.
The BT860 modules are ideal when designers need both performance and minimum size. For maximum
flexibility in integration, they support a host UART interface, I
2
S and PCM audio interfaces, GPIO, and
Cypress’GCI coexistence (2-Wire). The modules provide excellent RF performance and identical footprint options
for integrated antenna or an external antenna via a trace pin.
These modules present a Bluetooth standard HCI interface with support for Linux / Android and Embedded
Bluetooth software stacks for operating system backed devices. Additionally, Laird has partnered with Searan
for support of their ultra small, flexible ‘dotstack’ platform for embedded Cortex M3 and M4 implementations.
