GENERAL DESCRIPTION
The MK70215 is Bluetooth module operates in the 2.4 GHz ISM band. Embedded baseband /RF
transceiver LSI and protocol stacks up to Serial Port Profile(SPP) provide users with Bluetooth Class2
stable wireless connectivity and high performance. Equipped with UART/PCM interface, it is suitable
for both data/voice application purposes. This surface-mount type module can be mounted to users'
boards easily by soldering. The development TAT for Bluetooth-enabled end products can be shortened
very effectively by utilizing MK70215.

*2 The PCM_IN pins are pulled-up internally.
*3 The PCM_CLK, and PCM_SYNC pins are pulled-down internally.
*4 Setting the reset signal input pin RESET to a “L” level can reset the LSI. The reset state of the LSI is held for a
duration of 10 msec even after the reset signal is switched to a “H” level.
*5 Mount an approximately 10µF tantalum or electrolytic capacitor to the power supply input pin.
The capacitor should be mounted as close to the power supply pin of the module as possible.
* The PCM I/F is only valid in the HCI mode.

Notes on Mounting the Module
1. 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.
2. 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.
