CMM-9301-V3.1S
Bluetooth 4.0 Single Mode HCI Module

This Module is limited to OEM installation ONLY

C-MAX

Description

The CMM-9301-V3.1S module is a Bluetooth SIG qualified, miniaturised BLE controller module based
on EM Microelectronic's low power fully integrated single-chip Bluetooth Low Energy (BLE) Controller
EM9301. The module is highly optimized for Bluetooth 4.0 Single Mode (Bluetooth Low Energy) link
application requiring ultra low power consumption and short time-to-market. It offers a plug and play
solution for any BLE application up to the link layer, without any additional hardware nor RF layout.
Built in with a folded-dipole PCB antenna, this small sized, low cost module provides an ideal solution
to the new BLE technology.

The EM9301 is designed to act as BLE master or slave according to the Bluetooth 4.0 specification. It
can be controlled by any external microcontroller featuring BLE profile and applications, through the
standard BT HCI interface.

1.1 Features

o Bluetooth SIG qualified Controller Subsystem QDID: B020510

o Master and Slave BLE controller compliant to Bluetooth 4.0 specification
o Embedded low-power physical layer, Link Layer with security engine, and a Host Controller

Interface (HCI)

o Low average current consumption
o 1Mbps on-air data rate
o Mini-sized (18.5mm x 14mm)
o Integrated Battery Low Detection
o Programmable RF output level (-18 to +3 dBm) for current consumption optimization.
o No Tuning necessary
o SPI interface as HCI transport layer to micro-controller
