Entry Level ARM9 System-on-Chip Processor
Ethernet Media Access Controller (MAC)
The MAC subsystem is compliant with the ISO/TEC
802.3 topology for a single shared medium with several
stations. Multiple MII-compliant PHYs are supported.
Features include:
Supports 1/10/100 Mbps transfer rates for home /
small-business / large-business applications
Interfaces to an off-chip PHY through industry
standard Media Independent Interface (MII)
Serial Interfaces (SPI, I
2
S, and AC ’97)
The Serial Peripheral Interface (SPI) port can be
configured as a master or a slave, supporting the
National
Semiconductor
,
Instruments
signaling protocols.
Motorola
,
and
Texas
The AC'97 port supports multiple codecs for multichannel
audio output with a single stereo input. The I
2
S port
supports stereo 24-bit audio.
These ports are multiplexed so that the I
2
S port will take
over either the AC'97 pins or the SPI pins.
Normal Mode: One SPI Port and one AC’97 Port

S on SSP Mode: One AC’97 Port and one I

Note:

S may not be output on AC’97 and SSP ports at the
same time.
12-bit Analog-to-digital Converter (ADC)
The ADC block consists of a 12-bit analog-to-digital
converter with a analog input multiplexer. The multiplexer
can select to measure battery voltage and other
miscellaneous voltages on the external measurement
pins. Features include:
5 external pins for ADC measurement
Measurement pin input range: 0 to 3.3 V.
ADC-conversion-complete interrupt signal
