MT1020A
The MT1020A is a complete Bluetooth baseband processor It combines an
advanced ARM7TDMI based microcontroller with on-chip memory, a full duplex
voice CODEC and a dedicated Bluetooth Baseband Peripheral (BBP) block. The
BBP implements all the time-critical elements of Bluetooth communication in
hardware, with minimal involvement by the microcontroller. Relieving the
on-chip processor of these repetitive tasks makes it possible for the
MT1020A to run entire applications without an external host processor. A
UART Interface is provided for use when operation with an an external host
processor is required. Comprehensive power management maximises battery
life for portable applications making the MT1020A particularly suitable for
low power applications, especially those involving voice traffic.

Optimizing the Bluetooth Baseband Controller
for Portable Voice Applications (5/01) (PDF) Bluetooth Applications for
Voice+Data Bluetooth version 1.1 is ideal for devices that need to interact
at moderate data rates (under 1Mbit/sec) over a distance of a few metres,
when line-of-sight is an unacceptable limitation. It is particularly good
for hassle-free ‘ad hoc’ communication whenever a mobile Bluetooth
device comes within range of any other Bluetooth device. Voice is clearly a
very attractive option - some products absolutely depend on it and many
more can benefit from having it as an added feature.
