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.
