ATSAM3108B

• A small 256-Kbit external EEPROM with an SPI interface such as Atmel AT25256

• A DataFlash (current capacities range from 1Mbit to 64 Mbits) if audio storage functions are

required

• A SmartMedia card (supported capacities from 8 Mbytes to 128 Mbytes)

• The parallel MPU type interface.

I/O Selection Considerations

I/Os are organized in groups, which can be mutually exclusive because they share the same IC

pins (please refer to the pinout to identify the exclusions). The two main types of operation are

host controlled and stand-alone.

5.2.1

Host-controlled Operation

There are three main possible ways of communication with a host processor:

• 8-bit parallel MPU type bidirectional interface. Signals: D7 - D0, CS, WR, RD, A0, IRQ

• Asynchronous serial, MIDI_IN and optionally MIDI_OUT

• Synchronous serial. Signals: SDIN, SCLK, SYNC, INT

5.2.2

Stand-alone Operation

Possible stand-alone modes are:

• Firmware into external EEPROM or DataFlash

• Firmware into external SmartMedia. In this case, the firmware should reside in the

SmartMedia reserved sectors starting at sector # 1.
