ML7051LA
Bluetooth Baseband Controller IC
This version: Sept. 2000
GENERAL DESCRIPTION
The ML7051LA 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. Used in conjunction with the ML7050LA (Bluetooth RF Transceiver IC) and the OKI Bluetooth
Protocol Stack Software, data/voice communications are possible while maintaining interconnectivity with other
Bluetooth systems.
