Application Note
In summary, an SST39VF016 can be used on existing
Am29LV017D-based design without any board layout
changes when used in x16 mode.
Software Comparisons
The SST39VF016 uses the standard JEDEC command
set
Am29LV017D only uses JEDEC-compatible command
sequences. The command sets for basic device operations
between the two products are identical except that AMD
only specifies a subset of the standard JEDEC command
address bits e.g. AMD uses x555H, whereas SST uses
5555H. For more details, please refer to the data sheet of
each product.
TABLE 5: C
The Sector-Erase operations of SST and AMD devices use
the same six-byte command sequence with the same com-
mand data of 30H, but different sector addresses during
their sixth byte sequence. This is due to the difference in
sector architectures between SST and AMD products. The
Am29LV017D consists of one 8 KWord, two 4 KWord, one
16 KWord, and thirty-one 64 KByte sectors. On the other
hand, the SST39VF016 consists of 512 uniform 4 KByte
sectors. This difference in sector architectures results in the
SST device having more sectors than the AMD device.
Therefore, when a Sector-Erase operation is performed,
the SST device will use address lines A
sector addresses as opposed to the AMD device using
A
should be accounted for by the software driver.
In addition to the Sector-Erase command which erases
uniform small sectors, the SST39VF016 offers a Block-
Erase command. While a Sector-Erase operation erases
4 KByte sectors on an SST device, a Block-Erase opera-
tion erases 64 KByte blocks. Each block consists of six-
teen 4 KByte sectors. This flexible sector/block erasability
allows a system designer to use the Sector-Erase capa-
bility for finer software granularity and the Block-Erase
capability for faster Erase operations. Note that the AMD

device erases 64 KByte sectors using a Sector-Erase
command (30H), while the SST device erases 64 KByte
blocks using a Block-Erase command (50H).
In summary, when an SST39VF016 is used on an existing
Am29LV017D-based design, minor modifications to the
software driver are required.
For 8M flash products, the same analogies apply: the only
difference is that A
(Am29VF081B and SST39VF080) For 8M, however, AMD
doesn’t offer the BGA package, while SST offers one as a
low density migration from 16M.
SST AND ST MICROELECTRONICS
Comparisons with the ST Micro M29 series
ST Micro’s M29F series includes 512K, 1M, 2M, and 4M
devices; the M29F512, M29F010, M29F002 and
M29F040, respectively. ST Micro also has 512K, 1M, 2M,
and 4M devices in the M29W series - M29W512,
M29W010, M29W002, and M29W040.
For the SST39SF series, the corresponding devices
offered are SST39SF512 (512K), SST39SF010A (1M),
SST39SF020A (2M) and SST39SF040 (4M). For the
SST39VF series, the corresponding products offered are
SST39VF512 (512K), SST39VF010 (1M), SST39VF020
(2M) and SST39VF040 (4M)
TABLE 6: V
Hardware Comparisons
The ST Micro devices - the M29F010, the Am29F002N,
and the M29F040 are offered in 32-pin PLCC, PDIP , and
TSOP (8mm x 20mm) packages.
• 512K Pinout Comparison
The ST Micro M29F512 is offered in 32-pin PLCC, PDIP ,
and TSOP packages.
In the PLCC and PDIP packages, an SST39SF512 series
is fully pin compatible with an ST Micro M29F512 device.
As a result, the SST39SF512 device can be used in an ST
Micro design without any modifications in board layout.
For TSOPs, ST Micro offers both 8mm x 20mm and 8mm x
14mm packages. For an 8mm x 14mm package, SST 39
series devices are fully pin compatible with ST Micro’s
8mm x 14mm TSOP device of the same density, and can
