The MTC50150 is a low cost ADSL bridge and LAN router. One 10/100Mbits Ethernet port allows the con-
nection of a LAN to the WAN in bridged or routed mode. The data traffic can be routed through a local
terminal by using the LAN port. The presence of NAT and DHCP and the API slots for firewall functions
allow for a high-speed connection of LAN connected devices, like PC, to the public Internet in an isolated
and secure environment.
The chip is built around an ARM946ES RISC processor. It embeds a complete ADSL transceiver and LAN
interfaces with an MII allowing multiple medium utilization. A comprehensive software package is available
with the SOC solution, which has been developed with customization in mind. Several software license
plans are available as well as a user friendly development environment.
DESCRIPTION
4
The MTC50150 processor combines a DynaMiTe ADSL transceiver with a dedicated ARM946ES RISC
processor. To maintain high data throughput, the RISC processor includes 16Kbyte cache memory for
programming and 16Kbyte memory for data. Processing of most of the layer 2 protocols on the ATM (SAR
and AAL) and IP (Mac filter and bridge) sides are performed by specific hardware blocks, relieving the pro-
cessors from these tasks. The chip provides minimal external components and maximum flexibility. In ad-
dition, it contains one Ethernet 10/100 Base-T MAC and the exposed MII interface allows the connection
to alternate LAN mediums like HPNA, WLAN, and HPLUG. The MTC-50150 device is targeted for low-
cost residential gateways. Its primary design goal is to minimize cost. Secondary design goals are:
HARDWARE DESCRIPTION
– Low system cost using a reduced BOM and optimized SOC technology
– Low power to facilitate primary service capabilities and thermal system issues
– Low EMI to simplify packaging and qualification of systems
