Bluetooth HCI Data Module
®
BTM420/421
Innovative
Technology
for a
Connected
World
The BTM420 and BTM421 Bluetooth
®
modules are designed to meet the needs of
developers adding robust, short range Bluetooth data connectivity to their products
and using embedded Bluetooth stacks within these products. They are based on the
market-leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power
consumption with outstanding range. Supporting the latest Bluetooth Version 2.1
Specification with EDR (Enhanced Data Rate), HCI Data Modules increase data throughput
up to 2.1 Mbps. BT version 2.1 provides the advantage of Secure Simple Pairing that
improves security and enhances ease of use for end customers.
With a footprint as small as 12.5mm x 18.0mm and best-of-class low-power operation,
these modules are ideal for applications where designers need both performance and
minimum size. For maximum flexibility in systems integration, the modules are designed to
support separate power supplies for I/O and the USB interface.
These modules present an HCI interface and are fully qualified as Bluetooth Controller
Subsystem products. This also allows designers to integrate their existing pre-approved
Bluetooth Host and Profile subsystem stacks to gain a Bluetooth END product approval for
their products.
A low-cost developer’s kit is available for prototyping, ensuring a fast route to market.
