Fujitsu launches Multi-Service Access Controller for Tuesday 21 November 2000 PDF Print November 21st 2000. Fujitsu Microelectronics Europe has developed the MB86676 Multi-Service Access Controller chip to provide Segmentation and Reassembly (SAR) and Data Path Control functions within xDSL enabled set-top boxes and other xDSL Customer Premises Equipment (CPE). At the core of the MB86676 Access Controller chip is a 32-bit embedded ARC microprocessor with software to control all data transfers and traffic management through the integrated hardware. This powerful 100 MIPs processor delivers the performance demanded to enable higher level application specific protocol manipulation. The processor also allows for host control of Fujitsu’s MB86670 KeyWaveTM ADSL Modem or other network interface device via the generic memory interface. The processor is supported by a dedicated hardware SAR engine with embedded local RAM and address translation. The SAR function supports AAL5 (ATM Adaptation Layer 5) and manages ATM Forum CBR and UBR traffic classes on up to 32 Virtual Circuits (VCs). An integrated framer extracts the MPEG transport stream data from a specified Virtual Channel in order to directly interface to an MPEG-2 decoder such as Fujitsu's MB87L2250. The MB86676 has fully integrated user side interfaces for USB, typically for a PC host, and a 16-bit co-processor interface to provide a data connection to other processing devices such as wireless interface controllers and system controllers. The broadband data network side interface is UTOPIA level 2 for ATM cell throughput at up to 50 Mbps. The MB86676 has 8Kbytes of cache RAM and a total of 8Kbytes local SRAM for fast access to temporary storage, packet data, and configuration data. External memory is accessed via a 16/32-bit 100 MHz generic memory interface. Source code software is provided with the device for data transfer control, traffic management and interface drivers. Each function has its own Applications Programming Interface, and is easily ported to any RTOS. System integration with protocol stacks and user application software allows the set top box manufacturer to provide real differentiation of his product. The fact that the Multi-Service Access Controller can be interfaced to a range of Access transceivers (ADSL, SDSL and VDSL.), allows a common user interface to be maintained across the full set top box product range. The MB86676 is designed in 2.5 Volt CMOS with 3.3 Volt I/O, and housed in a 208pin QFP package. Pricing is less than $20 for 50K+ quantities. Samples will be available in Q2 2001.
