84C300A

The 84C300A is designed as 4-port fast ethernet controller.

84C300A has many features. The first one is it would have low power CMOS technology. The second one is 4-port ethernet controller optimized for switching hub, multiport bridge/router, server applications. The third one is supports 100baseT4, 100baseTX, 100baseFX & 10baseT transceivers. The fourth one is it meets ANSI/IEEE 802.3 and ISO 8802-3 standards for thicknet (10base-5), thin net (10base-2) and twisted pair (10base-T). The fifth one is standard 10MBit/sec serial mode or programmable MII ethernet interface for 10/100MBit/sec applications. The sixth one is preamble generation and removal. The seventh one is automatic 32-bit FCS (CRC) generation and checking. The seventh one is collision handling, transmission deferral and retransmission with automatic jam and backoff functions. The eighth one is single 5V ± 5% power supply. The ninth one is loopback capability for diagnostics. The tenth one is high bandwidth bus interface which means 32 bits x 33MHz and selectable big/little endianess. And so on. That are all the main features.

Some absolute maximum ratings of 84C300A 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 with respect to GND 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 last one is about its body temperature (soldering, 30 sec) which would be 220°C. And so on.
