General Description
BD2564CN is a Bluetooth 5.1 BR/EDR & LE dual mode transceiver module.
The module integrates Bluetooth classic and Bluetooth Low Energy radio TI’s CC2564C, a
26-MHz crystal oscillator, a band pass filter and all the passive components at a very
affordable cost.
The module provides the best-in-class RF performance with transmit power and receive
sensitivity that provides twice the range and higher throughput than other Bluetooth-
low-energy-only solutions. The power-management hardware and software algorithms
provide significant power savings in all commonly used Bluetooth BR/EDR and low energy
modes of operation.
The certified and royalty free Dual-mode Bluetooth 4.2 protocol stack software provides a complete Bluetooth BR/EDR,
and Bluetooth Low Energy sample applications that reduce design effort and ensure a faster time to market.
The module has a very small form factor with the dimensions of 7 mm x 7 mm x 1.55 mm.
Key Features
 Bluetooth 5.1 dual mode
 Bluetooth Basic Rate (BR)
 Enhanced Data Rate (EDR)
 Low Energy (LE)
 BR and EDR features include:
 Up to seven active devices
 Scatternet: Up to three piconets simultaneously,
one as master and two as slaves
 Up to two Synchronous Connection Oriented
(SCO) links on the same piconet
 Support for all voice air-coding – continuously
Variable Slope Delta (CVSD), A-Law, μ-Law,
modified Subband Coding (mSBC), and
transparent (Uncoded)
 Provide an assisted mode for HFP 1.6 Wideband
Speech (WBS) profile or A2DP profile to reduce
host processing and power
 Support of multiple Bluetooth profiles with
enhanced QoS
 Low Energy features include:
 Multiple sniff instances tightly coupled to
achieve minimum power consumption
 Independent buffering for Low Energy allows
large numbers of multiple connections without
affecting BR or EDR performance
 Built-In coexistence and prioritization handling
for BR, EDR, and Low Energy
 Capabilities of link layer topology, Scatternet -
can act concurrently as peripheral and central
 Network support for up to 10 devices
 Time line optimization algorithms to achieve
maximum channel utilization
 Best-in-Class Bluetooth (RF) performance (TX power,
RX sensitivity, blocking)
 Class 1 TX power up to +12 dBm
 Internal temperature detection and
compensation to ensure minimal variation in RF
performance over temperature, no external
calibration required
 Improved Adaptive Frequency Hopping (AFH)
 Algorithm with minimum adaptation time
 Longer range, including twice the range of
other Low-Energy-Only solutions
 Advanced power management for extended battery
life and ease of design
 On-Chip power management, including direct
connection to battery
 Low power consumption for active, standby,
