Supported Flash Memories:
There are currently 3 standard flash algorithm supported. The AMD, Intel and Atmel AT49 algorithm.
Almost all currently available flash memories can be programmed with one of this algorithm. The
flash type selects the appropriate algorithm and gives additional information about the used flash.
For 8bit only flash:
AM29F (MIRROR), I28BX8, AT49
For 8/16 bit flash in 8bit mode:
AM29BX8 (MIRRORX8), I28BX8 (STRATAX8), AT49X8
For 8/16 bit flash in 16bit mode:
AM29BX16 (MIRRORX16), I28BX16 (STRATAX16), AT49X16
For 16bit only flash:
AM29BX16, I28BX16, AT49X16
For 16/32 bit flash in 16bit mode:
AM29DX16, AM29BDDX16
For 16/32 bit flash in 32bit mode:
AM29DX32, AM29BDDX32
For 32bit only flash:
M58X32
The AMD and AT49 algorithm are almost the same. The only difference is, that the AT49 algorithm
does not check for the AMD status bit 5 (Exceeded Timing Limits).
Only the AMD and AT49 algorithm support chip erase. Block erase is only supported with the AT49
algorithm. If the algorithm does not support the selected mode, sector erase is performed. If the chip
does not support the selected mode, erasing will fail. The erase command sequence is different only
in the 6th write cycle. Depending on the selected mode, the following data is written in this cycle (see
also flash data sheets): 0x10 for chip erase, 0x30 for sector erase, 0x50 for block erase.
To speed up programming of Intel Strata Flash and AMD MirrorBit Flash, an additional algorithm is
implemented that makes use of the write buffer. This algorithm needs a workspace, otherwise the
standard Intel/AMD algorithm is used.
