The CS8900A-IQ3Z is a low-cost Ethernet LAN Controller optimized for the Industry Standard Architecture (ISA) bus and general purpose microcontroller busses. Its highlyintegrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900A includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct ISA-Bus interface with 24 mA Drivers.
Features of the CS8900A-IQ3Z are:(1) single-chip IEEE 802.3 ethernet controller with direct ISA-Bus interface;(2) maximum current consumption is 55 mA (5V supply);(3) 3 V or 5 V operation;(4) comprehensive suite of software drivers available;(5) efficient packetPage™ architecture operates in I/O and memory space, and as DMA slave;(6) full duplex operation;(7) on-chip RAM buffers transmit and receive frames.
The absolute maximum ratings of the CS8900A-IQ3Z can be summarized as:(1): input current (except supply pins)is±10.0 mA max;(2): analog input voltage is -0.3 V min and (AVDD+)+ 0.3 V max;(3): digital input voltage is -0.3 V min and (DVDD)+ 0.3 V max;(4): ambient temperature (power applied) is -55°C min and +125°C max; (5): storage temperature is -65°C min and +150°C max.
