GENERAL DESCRIPTION

The ML7055 is a CMOS digital IC for use in 2.4 GHz band Bluetooth™ systems. This IC incorporates the

ARM7TDMI£ as the CPU core, features a highly expandable architecture, and supports the interfaces for a variety

of applications. Since the ML7055 has Oki’s Bluetooth protocol stack software installed, when the IC is used in

conjunction with the Bluetooth RF transceiver IC, data/voice communications are possible while maintaining

interconnectivity with other Bluetooth systems.
