Oki
Semiconductor's Bluetooth Solution
Oki Semiconductor's Bluetooth solution meets version 1.1 of the
Bluetooth standard for short-range wireless applications. It includes:
Oki
Bluetooth Chipset
Oki's Bluetooth chipset consists of the RF Receiver (ML7050LA)
and the Baseband controller (ML70511LA).
The Oki Bluetooth RF transceiver (ML7050LA)
is a highly integrated systems-based IC that is designed to operate in the
2.4 GHz Industrial, Scientific and Medical (ISM) bands. The ML7050LA is
packaged in a 48-pin ball grid array package and requires only 7-milimeters
of the systems critical board space.
The baseband controller (ML70511LA)
incorporates the ARM7TDMI as the CPU core and is highly expandable and
adaptable for multiple applications. Together, the ML7050LA and ML70511LA
form a highly compatible and complete hardware solution enabling data/voice
communications while maintaining interoperability with other Bluetooth
systems.
ML7050LA RF Transceiver
The Oki ML7050LA comprises all necessary functions to eliminate the need
for adjustments and external SAW filter. Implemented in RF-CMOS technology
and packaged in F-BGA, the small device is a fully featured Bluetooth RF
transceiver LSI performing at low noise and high efficiency.

ML70511LA Baseband Controller
The Oki ML70511LA is a self-contained Bluetooth baseband controller LSI
coring an ARM7TDMI ® with system RAM. The peripheral bus includes user
inter- faces, such as USB 1.1, I/Os and Voice. A plug-in is provided for a
user or application IP as is an efficient power management. A built-in
Flash memery version is the ML70Q5111LA.

Oki
Semiconductor Announces BQB Qualification for Bluetooth Chipset (9/01)
Oki Semiconductor announces it has received Bluetooth Qualification
Body (BQB) certification for its Bluetooth RF transceiver chip. Along with
the full BQB qualification of Oki's baseband controller and link manager,
the announcement completes the certification of the Oki Bluetooth chipset,
extending the company's leadership in chipset and module solutions.

Bluetooth Modules
The preassembled Bluetooth Module integrates a 2.4-GHz RF transceiver,
baseband controller, and software. All fully compliant with version 1.1 of
the Bluetooth standard. The Module incorporates the Bluetooth chipset
(ML7050LA RF transceiver, ML70511LA baseband controller). Memory and other
components, and, for added flexibility, both an antenna port and a
connector.
These modules are ready-made functional 2.4GHz Bluetooth data/voice
communication systems for shortest possible design-in time. Conforming to
Bluetooth Version 1.1, the 18 x 39 mm sized module integrates Oki's
Bluetooth chip set, Bluetooth software and a 20-pin connector. It provides
Class 2 output power and is offered in two variations:
- MK70110 with coaxial connector, U.FL.R-SMT/HRS, (no antenna)
- MK70120 with on-board chip antenna, ANCM12G45/Murata, (no coaxial
connector)

/ MK70120 Modules
Oki Semiconductor's MK70 Series modules are for use in 2.4 GHz band
Bluetooth systems. These modules incorporate Bluetooth baseband and RF
transceiver ICs, Flash memory, and TCXO. Using one of Oki's MK70 Series
modules, a user's turnaround time for 2.4 GHz Bluetooth data/voice
communication device development is reduced to the shortest possible time.
Available in the MK70 Series are the MK70110 and MK70120 modules which are
without antenna and with antenna, respectively.
