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.

*1 Relaxed C/I specification
On five spurious response frequencies with a distance of
2 MHz from the wanted signal (except for
image frequency and image 1 MHz), a relaxed interference requirement C/I = 17 dB is applied.
(According to Bluetooth Specification 1.1, Part A Radio Specification)
*2 Image Frequencies and adjacent interference to image
Image frequency = Co-channel 4 MHz
1 MHz adjacent interference to image frequency = Co-channel 3 MHz, Co-channel 5 MHz
