PCF87852
Bluetooth baseband controller
Rev. 01 — 23 April 2004
Preliminary data
1. General description
www.DataSheet4U.com
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.

11. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
12. Disclaimers
Life support — These products are not designed for use in life support
appliances, devices, or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors
customers using or selling these products for use in such applications do so
at their own risk and agree to fully indemnify Philips Semiconductors for any
damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to
make changes in the products - including circuits, standard cells, and/or
software - described or contained herein in order to improve design and/or
performance. When the product is in full production (status ‘Production’),
relevant changes will be communicated via a Customer Product/Process
Change Notification (CPCN). Philips Semiconductors assumes no
responsibility or liability for the use of any of these products, conveys no
licence or title under any patent, copyright, or mask work right to these
products, and makes no representations or warranties that these products are
free from patent, copyright, or mask work right infringement, unless otherwise
specified.
13. Licenses
Purchase of Philips I2C components
Purchase of Philips I2C components conveys a license
under the Philips’ I2C patent to use the components in the
I2C system provided the system conforms to the I2C
specification defined by Philips. This specification can be
ordered using the code 9398 393 40011.
