Note:
1. The AVR micro controller cannot be clocked at 16MHz since this configuration
requires a 4.5V minimum power supply whereas NAND Flash or SD/MMC devices do
not withstand such a voltage level on I/Os. However, DataFlash are 5V-tolerant, and
speed measurements have been done independently of this evaluation board: for
45DB321, write speed is 40KB/sec and read speed is 300KB/sec. For 45DB642,
write speed is 80KB/sec and read speed is 300KB/sec.
2. In the K9K2G08UOM device, the COPYBACK instruction cannot be used in all the
memory plane, since it is efficient only between size-limited zones. This problem con-
cern several other memorie devices.
3.2.2
Direct limitations
The limitations on reading operations are:
– Dataflash: SPI bus frequency, internal read access speed
– SD/MMC: SPI bus frequency, internal read access speed
– NAND Flash: USB maximum data rate
The limitations on writing operations are:
– Dataflash: internal write access speed, page write duration & size, SPI bus
frequency
– SD/MMC: internal write access speed and duration, SPI bus frequency
– NAND Flash: memory internal writing structure (COPYBACK support or not,
page write and block erase duration, page size), USB maximum data rate
