Micrel, Inc.
Integrated MAC and PHY Ethernet Controller fully
compliant with IEEE 802.3/802.3µ standards
Designed for high performance and high throughput
applications
Supports 10BASE-T/100BASE-TX
Supports IEEE 802.3x full-duplex flow control and half-
duplex backpressure collision flow control
Supports DMA-slave burst data read and write
transfers
Supports IP Header (IPv4)/TCP/UDP/ICMP checksum
generation and checking
Supports IPv6 TCP/UDP/ICMP checksum generation
and checking
Automatic 32-bit CRC generation and checking
Simple SRAM-like host interface easily connects to
most common embedded MCUs.
Supports multiple data frames for transmit and receive
without address bus and byte-enable signals
Supports both Big- and Little-Endian processors
Larger internal memory with 12K Bytes for RX FIFO
and 6K Bytes for TX FIFO. Programmable low, high
and overrun watermark for flow control in RX FIFO
Shared data bus for Data, Address and Byte Enable
Efficient architecture design with configurable host
interrupt schemes to minimize host CPU overhead and
utilization
Powerful and flexible address filtering scheme
Optional to use external serial EEPROM configuration
for MAC address
Single 25MHz reference clock for both PHY and MAC
HBM ESD Rating 6kV
Single 3.3V power supply with options for 1.8V, 2.5V
and 3.3V VDD I/O
Built-in integrated 3.3V or 2.5V to 1.8V low noise
regulator (LDO) for core and analog blocks
Enhanced power management feature with energy
detect mode and soft power-down mode to ensure
low-power dissipation during device idle periods
Comprehensive LED indicator support for link, activity
Low-power CMOS design
Commercial Temperature Range: 0°C to +70°C
Industrial Temperature Range: –40°C to +85°C
and 10/100 speed (2 LEDs) - User programmable
