OKI Semiconductor MK70110/MK70120
Bluetooth Module
PEDLMK70-02
Issue Date: Apr. 24, 2002
Preliminary
GENERAL DESCRIPTION
The MK70110 and MK70120 are Bluetooth modules that operate in the 2.4 GHz band. Mounted on the board of each of these modules are Bluetooth baseband & RF transceiver IC, RF filter, flash memory, and TCXO. Lower protocol stacks up to the HCI are already installed in these modules as software. These modules can be connected to user's board product by using the connector the modules have. Since the modules are provided not only with the UART and USB interfaces as communication control interfaces but with a PCM interface as a voice control interface, they can cope with any application for data and voice communication. The MK70110 is equipped with an RF coaxial connector, and the MK70120 has a chip antenna built-in. By utilizing the MK70110/MK70120, the development TAT for products equipped with Bluetooth can be shortened very effectively.

MOUNTING MODULE
Recommended Module Fixing Method When this module is fixed on a product, our recommended method is to fit the module board-to-board connector (header) into the board-to-board connector (socket) mounted on the product board, and to solder the module shielding case to the product board.

Notes on Mounting the Module 1. This module is not adaptable to reflow mounting. When soldering the shielding case to a product board, use a soldering iron. 2. If metal is placed around the antenna, the antenna characteristics may deteriorate. Do not place copper foil in the pattern inhibiting zone shown in the above section. Do not place metal around the antenna if possible. (Only for MK70120). 3. The shielding case is connected to GND in the module. For mounting the module, when pattern wiring that touches the shielding case is carried out on the product board, do not cause a short-circuit between the shielding case and the pattern. For example, apply resist on the entire surface that touches the shielding case. 4. The effects of noise on a product board depend on the connection of GND/NC to the fixation pads. Select the connection with better electrical characteristics in the module mounted state.
CAUTIONS IN USE
This module consists of precision electronic components. Therefore, note the following when handling the module: 1. In a case of decomposition or recomposition of this module, the operations in these specifications are not assured. 2. This module is not waterproof or drip-proof. Do not use the module in wet locations. 3. Do not use this module under high temperature or high humidity conditions, in direct sunlight, or in dusty places.
