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. 2.

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.
