84302

The 84302 is designed as quad 100/10 Mbps ethernet controller with RMON/SNMP management counters. The 84302 integrates four independent channels on one IC.

84302 has many features. The first one is improved version of SEEQ 84301 & 84C300. The second one is four independent MAC channels. The third one is 100/10 Mbps. The fourth one is full RMON, SNMP and ethernet management counter support per port. The fifth one is about its 32-bit, 50MHz interface to external bus - 1.6Gbps bandwidth. The sixth one is MII and 7-wire interface to external PHY. The seventh one is 16-bit interface to internal registers and management counters. The eighth one is management interface (MI) to external PHY. The ninth one is independent 128 byte receive & transmit FIFO's per port with programmable watermarks. The tenth one is full and half duplex. The eleventh one is automatic CRC generation and checking. And so on. That are all the main features.

Some absolute maximum ratings of 84302 have been concluded into several points as follow. The first one is about its Vcc supply voltage which would be from -0.3V to 6.0V. The second one is about its all inputs and outputs which would be from -0.3V to Vcc+0.3V. The third one is about its package power dissipation which would be 2.2W at 70°C. The fourth one is about its storage temperature range which would be from -65°C to +150°C. The fifth one is about its temperature under bias which would be from -10°C to +80°C. The sixth one is about its lead temperature (soldering, 10sec) which would be 260°C. The seventh one is about its body temperature (soldering, 30 sec) which would be 220°C. It should be noted that absolute maximum ratings are limits beyond which may cause permanent damage to the device or affect device reliabily. And so on.
