• Manufacturer Part Number: AM29SL160C
• Description: 16 Megabit CMOS 1.8 Volt-only Super Low Voltage Flash Memory
• Manufacturer: AMD [Advanced Micro Devices]

During the unlock bypass mode, only the Unlock
Bypass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset
command sequence. The first cycle must contain the
data 90h; the second cycle the data 00h. Addresses
are don’t cares. The device then returns to reading
array data.
The device offers accelerated program operations
through the WP#/ACC pin. This function is intended
only to speed in-system programming of the device
during system production. When the system asserts
V
enters the Unlock Bypass mode. The system may then
write the two-cycle Unlock Bypass program command
sequence. The device uses the higher voltage on the
WP#/ACC pin to accelerate the operation. Note that
the WP#/ACC pin must not be at V
other than accelerated programming, or device
damage may result. In addition, the WP#/ACC pin must
not be left floating or unconnected; inconsistent
behavior of the device may result.
