Single-chip Bluetooth device with fully integrated Human

Interface Device (HID) profile and full Bluetooth stack

On-board 8051 processor and RAM/ROM memory

Custom-integrated Bluetooth core processor has been

optimized to support the HID profile and minimize power

consumption

Bluetooth version 1.2 compliant including support for adaptive

frequency hopping and fast connect

Fully integrated radio eliminates all filters and matching

components and features a single-pin interface directly to

antenna

Direct interface to keyboard scan matrix with full support for

152 keys and user-customizable hot keys

Integrated quadrature signal decoder to support both ball and

optical mouse designs

Direct interface to LED and LCD displays

Drive capability to power external optoelectronics

ROM-based design eliminates external flash memories

• Flash option offered to support feature development

Fully integrated low dropout (LDO) regulator provides

direction interface to batteries

Available in 64-pin fpBGA and 100-pin fpBGA packages

Bluetooth mouse

Bluetooth keyboard

Combination mouse/keyboard

Cost-optimized solution for mouse and keyboard applications

- not a generic HCI device adapted for mouse and keyboard

• Achieves lowest possible cost through the integration of all

• Direct interface to key scan matrix or ball/optical mouse

Replaces existing mouse or keyboard processor and memory

and adds Bluetooth functionality

Lowest power consumption solution provides greater than six-

month battery life

Adaptive frequency hopping support ensures full

interoperability and coexistence with WLAN enabled personal

computers

Optimized radio provides long-range, interference-free

operation in high-interference environments

• Transmitter provides +4 dBm output power and satisfies Class

• Receiver provides -85 dBm receiver sensitivity

Single monolithic bulk CMOS device providing low cost and

high availability of manufacturing supply
