Description
The AT49SN/SV12804 is a 1.8-volt 128-megabit Flash memory. The memory is
divided into multiple sectors and planes for erase operations. The AT49SN/SV12804
is organized as 8,388,608 x 16 bits. The device can be read or reprogrammed off a
single 1.8V power supply, making it ideally suited for In-System programming. The
device can be configured to operate in the asynchronous/page read (default mode) or
burst read mode (not available for the AT49SV12804). The burst read mode is used to
achieve a faster data rate than is possible in the asynchronous/page read mode. If the
AVD and the CLK signals are both tied to GND and the burst configuration register is
configured to perform asynchronous reads, the device will behave like a standard
asynchronous Flash memory. In the page mode, the AVD signal can be tied to GND or
can be pulsed low to latch the page address. In both cases the CLK can be tied to
GND.
The AT49SN/SV12804 is divided into thirty-two memory planes. A read operation can
occur in any of the thirty-one planes which is not being programmed or erased. This
concurrent operation allows improved system performance by not requiring the sys-
tem to wait for a program or erase operation to complete before a read is performed.
To further increase the flexibility of the device, it contains an Erase Suspend and Pro-
gram Suspend feature. This feature will put the erase or program on hold for any
amount of time and let the user read data from or program data to any of the remain-
ing sectors. There is no reason to suspend the erase or program operation if the data
to be read is in another memory plane.
The VPP pin provides data protection and faster programming and erase times. When
the V
PP
input is below 0.4V, the program and erase functions are inhibited. When V
PP
is at 0.9V or above, normal program and erase operations can be performed. With V
PP
at 12.0V, the program (Dual-word Program command) and erase operations are
accelerated.
