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 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, 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 ARM7TDMI
TM
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
• I
2
C 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
