Description
Single channel memory controller with an ECC enabled 64-bit interface that,
depending on SKU, supports external DDR-2 memory (400, 533, 667 and 800
1 MHz). Minimum memory size is 128 MB (in 32 bit mode). Maximum memory size
is 4GB. The EP80579 integrated processor also supports a 32-bit mode (with
ECC) for cost-sensitive applications.
1 Supports 1x8, 2x4, or 2x1 configurations as a root complex.
3
10/100/1000 Gigabit Ethernet MACs with RGMII/RMII interface. Two of the three
ports support IEEE 1588 hardware assist.
8.192 MHz high-speed synchronous serial TDM interfaces that support up to 12
3 T1/E1 links (SKU dependent) with Intel software driver provided for HDLC
support.
1 25/16-bit 80MHz local expansion bus with 8 programmable chip selects.
1
Universal Serial Bus 2.0 host controller interface, supports two USB ports (shared
with USB1.1 ports)
1
Universal Serial Bus 1.1 host controller interface, supports two USB ports (shared
with USB2.0 ports)
1
Low Pin Count Bus (LPC) interface to attached PC compatible boot flash memory
up to 64MB.
1 Serial Peripheral Interface (SPI).
36
Programmable General Purpose I/O (GPIO) pins. Note, Intel recomends using this
interface to boot from. Of the 36pins, many have alternate functions defined.
2 I2C compatible SMBus2.0 connections.
2
16550 compatible asynchronous serial ports that support data rate of at least
115Kbits/sec.
2 SATA1.0 or 2.0 used to attached external hard drives.
1 Synchronous Serial Port
2 Controller Area Network interfaces.
1 MDIO interface to support the ethernet interfaces.
1 IEEE-1588 Hardware Assist
