The BTM420 and BTM421 Bluetooth

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.
