Byte-Program Operation
The SST37VF512/010/020/040 are programmed by using
an external programmer. The programming mode is acti-
vated by asserting 12V (±5%) on OE# pin and V
IL
on CE#
pin. The device is programmed using a single pulse (WE#
pin low) of 10 μs per byte. Using the MTP programming
algorithm, the Byte-Program process continues byte-by-
byte until the entire chip has been programmed. Refer to
Figure 10 for the flowchart and Figure 6 for the timing dia-
gram.
Chip-Erase Operation
The only way to change a data from a
“
0
”
to
“
1
”
is by electri-
cal erase that changes every bit in the device to
“
1
”
. The
SST37VF512/010/020/040 use an electrical Chip-Erase
operation. The entire chip can be erased in 100 ms (WE#
pin low). In order to activate erase mode, the 12V (±5%) is
applied to OE# and A
9
pins while CE# is low. All other
address and data pins are
“
don
’
t care
”
. The falling edge of
WE# will start the Chip-Erase operation. Once the chip has
been erased, all bytes must be verified for FFH. Refer to Fig-
ure 9 for the flowchart and Figure 5 for the timing diagram.
Product Identification Mode
The Product Identification mode identifies the devices as
SST37VF512,
SST37VF010,
SST37VF040 and manufacturer as SST. This mode may
be accessed by the hardware method. To activate this
mode, the programming equipment must force V
H
(12V±5%) on address A
9
. Two identifier bytes may then be
sequenced from the device outputs by toggling address
line A
0
. For details, see Table 3 for hardware operation.
SST37VF020,
and
Design Considerations
The SST37VF512/010/020/040 should have a 0.1μF
ceramic high frequency, low inductance capacitor con-
nected between V
DD
and GND. This capacitor should be
placed as close to the package terminals as possible.
OE# and A
9
must remain stable at V
H
for the entire dura-
tion of an Erase operation. OE# must remain stable at V
H
for the entire duration of the Program operation.
