PCF87852
Bluetooth baseband controller
Rev. 01 — 23 April 2004
Preliminary data
1. General description
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 I2C-bus™, PCM and IOM® are supported by
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.

7. Functional description
The PCF87852 is designed to be used as a low-cost, low-power radio-based cable
replacement, or wireless link. This link will be the basis for PCs, telephones, PDAs
headsets and peripherals to communicate together on an ad-hoc basis. It is designed
to handle the Bluetooth specification.
The PCF87852 is intended to combine the Bluetooth protocol stack, link controller,
link manager, HCI Firmware and radio of the Bluetooth system specification in one IC
with embedded software. Figure 2 shows a typical example of the PCF87852 in its
environment. Together with few external components and an antenna it forms a
Bluetooth system. In most cases this system will be attached to a host, for example a
GSM baseband controller or a PC processor.
The industry standard ARM7TDMI microcontroller with low power consumption per
MHz is integrated. There is a ROM memory and a static RAM on-chip. There are no
provisions for external controllers to directly access on-chip data memories.
Communication with an external host, for example a PC, GSM or PDA, is handled via
the HCI.
The PCF87852 is able to run the complete Bluetooth application up to HCI.
A number of industry standard interfaces such as IOM/PCM, I2C-bus, and UART are
supported by on-chip hardware to act as possible host interfaces.
The Bluetooth link 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 VLSI Peripheral Bus (VPB).
Figure 1 shows the various blocks and their interconnections.
