Introduction
Conexant Proprietary and Confidential Information
The Conexant™ CX82100 Home Network Processor (HNP) is a single-chip, 185 MIPS
high performance, ARM940T-based processor integrated with multiple network interface
hardware functions and packaged into a 196-pin FPBGA. Embedded firmware supports
complete networking system solutions in a wide variety of commercial, industrial,
business, SOHO, and home applications with appropriate host software.
Typical applications include a Residential Gateway (RG) with network address
translation (NAT)/firewall services, or a HomePNA 2.0 or HomePlug 1.0 Bridge when
the CX82100 HNP is combined with a standard 10/100 Ethernet PHY or Home
Networking PHY such as Conexant’s CX24611 HomePNA 2.0 PHY/AFE.
The CX82100 HNP is available in different models to support basic functions,
programmable HRDY# polarity for 802.11b applications, higher throughput (higher
FCLK frequency), and ability to run Intoto Firewall software (Table 1-1).

[196-pin FPBGA]
CX82100-11 supports basic functions. HRDY#, for wireless applications, is not
supported. The CX82100-11 supports the following two signals on the indicated pins
(different from the CX82100-41): P13 = VSS0 and P14 = HC00 (HCS0#)/GPIO32
(see Section 2.1.1).
CX82100-12 supports basic functions and Intoto Firewall software. Same pinout as
the CX82100-11.
CX82100-51 supports basic functions and higher frequency operation (FCLK to 168
MHz). Same pinout as the CX82100-11.
CX82100-52 supports basic functions, higher frequency operation (FCLK to 168
MHz), and Intoto Firewall software. Same pinout as the CX82100-11 and CX82100-
12.
CX82100-41 supports basic functions and programmable HRDY# polarity for
wireless applications (see Section 5.1.6). The CX82100-41 supports the following
two signals on the indicated pins (different from the CX82100-11): P13 = HC00
(HCS0#)/GPIO32 and P14 = HC10 (HRDY#) (see Section 2.1.2). Recommended for
new designs.
