1. General description

2. Features

2.1 Baseband hardware

The PCF87852 combines the Bluetooth™ protocol stack, Link Controller (LC), Link

Manager (LM), and Host Controller Interface (HCI) ﬁrmware of the Bluetooth system

speciﬁcation in a single IC with embedded software. Together with an RF module, a

few external components and an antenna it forms a Bluetooth system. In most cases

this module will be attached to a host, for example a GSM baseband controller or a

PC processor. The PCF87852 may also be used for embedded Bluetooth

applications by running the upper software layers also from the on-chip memory.

Together with an external voice codec a Bluetooth headset application can be

realized.

The industry standard ARM7TDMI™ microcontroller with low power consumption is

integrated together with ROM memory and SRAM. There are no provisions for

external controllers to directly access on-chip data memory. Communication with an

external host, for example a PC, GSM or PDA, is handled via the HCI.

Industry standard interfaces such as I

on-chip hardware. Additionally, a UART interface is available that can be used as the

Bluetooth host controller interface.

The Bluetooth controller consists of a number of functional blocks that operate under

control of the embedded microcontroller. The microcontroller has access to these

blocks via the AMBA System Bus (ASB) and the VLSI Peripheral Bus (VPB).

The PCF87852 is designed to be used together with an RF IC as low-cost,

low-power, radio-based cable replacement or wireless link. This link will be the basis

for PCs, telephones, PDAs and peripherals to communicate together on an ad-hoc

basis. It will replace cables and enables a wireless personal network.

The PCF87852 is especially suited for applications without the need for analog voice

input or output, e.g. cellular telephones or computing platforms.
