NB! Not valid: AT45D021 2-Mbit DataFlash is included on the STK500 for data storage.
A DataFlash is a high-density Flash memory with SPI serial interface. A detailed
datasheet of the DataFlash can be obtained from the Flash memory section of the Atmel
CD-ROM or from the Atmel web site.

The DataFlash can be connected to the I/O pins of the microcontroller sockets. The
4-pin header marked “DATAFLASH” can be used for connecting the SPI interface of the
DataFlash to the I/O pins on the target AVR microcontroller in the socket. 2-wire cables
are included with STK500 for connecting the DataFlash to the I/O pins. The supplied
10-wire cables can also be used if the DataFlash is connected to the hardware SPI inter-
face on PORTB of the AVR microcontroller. The connection of the I/O pins is shown in
Figure 3-13. The block schematic of the DataFlash connection is shown in Figure 3-14,
for connection of the DataFlash to the AVR hardware SPI interface. The SPI interface
pinout is shown in Figure 3-11 and Figure 3-12.
