Product Overview
Chapter 1 Product Overview
1.1 Overview
ADM5120 is a high performance, highly integrated, and highly flexible SOC (System-
On-Chip) that facilitates the functionalities of SOHO/SME Gateway, NAT Router, Print
Server, WLAN Access Point, and VPN Gateway. ADM5120 enables the sharing of IP-
based broadband services throughout the home/office using wired/wireless computers,
entertainment equipment, printers, and other intelligent devices.
Internally, the ADM5120 ASIC consists of a high performance (227 MIPS) embedded
MIPS CPU, an embedded switch engine, 10/100M PHY, an embedded PCI bridge, an
embedded USB host, and interfaces for UART, SDRAM, Flash and VPN engines. The
following diagram illustrates a system configuration that uses the supported
functionalities/facilities of ADM5120.
1.1.1 Product Order Information
The ADM5120 comes in two packaging formats as follows:
Section 2.1 Ball Grid Array (BGA) 324-pin
Section 2.2 Plastic Quad Flat Pack (PQFP) 208-pin
