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.

FEATURES

? Conforms to Bluetooth Specification (Ver1.1)

? Designed for connection with the RF-LSI interface, such as the OKI RF-LSI interface (ML7050), the

SKYWORKS RF-LSI interface (CX72303), or the BROADCOM RF-LSI interface (BCM2002X) that

functions as the Bluetooth RF-LSI interface

? The high-speed, low-power ARM7TDMITM is installed as the CPU core

? PCM-CVSD transcoder that provides high quality voice using the noise filter is installed

? Low power consumption in flexible power management modes according to operating modes of Bluetooth

? DETACH signal provides control of change to power-saving mode (STOP) and return request to normal mode.

? UART interface corresponding to baud rates up to 921.6 kbps

? I2C bus interface provides accesses to EEPROM or PCM-Codec

? Selactable 12 MHz or 13 MHz for the system clock

? Selectable 32 kHz or 32.768 kHz for the LPO clock

? Built-in programmed ROM eliminates external ROM/FLASH

? The packages are available in three types:

63-pin WCSP for ML7055HB

64-pin BGA for ML7055LA

84-pin BGA for ML7055LP
