Section 1: Overview
INTRODUCTION
The BCM92046MD_EMB is a Bluetooth® embedded module based on the BCM2046 Bluetooth 2.1
specification-compliant stand-alone baseband processor with an integrated 2.4 GHz transceiver. It is fully
compliant with the Bluetooth radio specification and incorporates new modulation schemes to support
enhanced data rates (EDRs) of 2 Mbps and 3 Mbps. The BCM92046MD_EMB module supports both UART
and Universal Serial Bus (USB) version 2.0 full-speed interfaces, and is fully compatible with the HCI interface
specification. The module includes EEPROM, a crystal, and a Printed Circuit Board (PCB) antenna.
FEATURES
The module supports the following features:
•A Bluetooth 2.1 compliant embedded USB module with the following features:
- Secure Simple Pairing (SSP)
- Link Supervision Time Out (LSTO)
- Encryption Pause Resume (EPR)
- Enhance Inquiry Response (EIR)
- Sniff Subrating (SSR)
- Erroneous Data (ED)
- Packet Boundary Flag (PBF)
•A Programmable collaborative coexistence interface
•Class 1 output power capability
•Class 2 RF maximum output power specification of 4 dBm
•Full piconet and scatternet operation
•EDR rates of 2 MBps and 3 MBps
•A high-speed UART interface
•A USB 2.0 full-speed compliant interface
•Built-in Low Power Oscillator (LPO) clock or operation using an external LPO clock
•Full support for power-saving modes.
•Advanced Audio Distribution Profile (A2DP)
•Upgradeable firmware through an EEPROM download
•A PCB antenna

MODULE PINOUT DESCRIPTION
Table 1 shows the BCM92046MD_EMB pinout description.
APPLICATION CODE
Application code resides in the on-module EEPROM. During power-on reset, the application code must be
downloaded to BCM2046 RAM before the board performs any Bluetooth activity.
Application code can also be patched directly to BCM2046 RAM from the host during power-on reset without
an external EEPROM.
The 2046 on-chip serial port can be used to download application code from a host computer file to EEPROM
or on-chip RAM using either the UART or USB transport mechanisms.

Declaration of Conformity Label & Marking Requirements
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: The user is cautioned that any changes or modifications not expressly approved by
Renishaw plc, or authorised representative could void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired
operation.
