Specifications of 78Q8340-ARM9-EVM

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

specifically for the Audio/Visual (A/V) and Set Top Box (STB) markets and is easily interfaced to available
A/V and STB core processors.
The 78Q8430 is compliant with applicable IEEE-802.3 standards. MAC and PHY configuration and
status registers are provided as specified by IEEE802.3u. The integrated MAC is supported by an
internal 32KByte transmit and receive SRAM FIFO. The partition of transmit and receive queues is
configurable through software, allowing the 78Q8430 to be tuned for specific applications. The device
contains hardware support for TCP-IP checksum and ARC address recognition.
The D8430T3A_EB provides support for the following 78Q8430 hardware interface features:
•
•
•
•
•
•
•
A host processor interfaces directly to the FIFO via the Global Bus Interface (GBI). The D8430T3A_EB is
configured for 32-bit big endian bus format.
1 Introduction
The 78Q8430 Embest Evaluation Board (D8430T3A_EB) is a design example for a 10/100BASE-TX
MAC+PHY Embest S3CEB2410 daughter card. The D8430T3A_EB plugs directly into the Embest
S3CEB2410 (ARM9
a single chip auto-sensing, auto-switching (auto-negotiation or parallel detect modes and auto-MDIX)
10/100BASE-TX Fast Ethernet transceiver with full duplex operation capability. The device is designed
