Bluetooth Baseband Controller IC
FEDL70512-04
Issue Date: Sep. 2, 2003
GENERAL DESCRIPTION
The ML70512 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 ML70512 has Okiâs 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, ML70561), 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, 13 MHz, or 16 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 two types:
83-pin WCSP for ML70512HB
84-pin BGA for ML70512LA
