Data Sheet
AUTO-ADDRESS INCREMENT (AAI) MODE
AAI Mode with Multi-byte Programming
AAI mode with multi-byte programming is provided for high-
speed production programming. Auto-Address Increment
mode requires only one address load for each 128-byte
page of data.
Taking the WP#/AAI pin to the Supervoltage V
the AAI mode. The AAI command is started as a normal
Firmware Memory cycle. LD# should be low (V
as data is being loaded into the device. In the MADDR field,
the host may input any address within the 128-byte page to
be programmed. The least significant seven bits of the
address field will be ignored and the device will begin pro-
gramming at the beginning of the 128-byte page (i.e., the
address will be page-aligned). The device Ready/Busy sta-
tus is output on the RY/BY# pin.
Data is accepted until the internal buffer is full. At that point
RY/BY# goes low (busy) to indicate that the internal buffer
is full and cannot accept any more data. When the device
is ready, RY/BY# pin goes high and indicates to the host
that more data (the next group of bytes) can be accepted
by the internal data buffer (see Table 18 and Figure 9).
After loading the final byte(s) of the 128-byte page, the RY/
BY# signal remains low until the completion of internal pro-
gramming. After the completion of programming, the part
will go into idle mode and the RY/BY# will go high indicating
that the AAI command has been completed (see Table 18).
A subsequent AAI command may be initiated to begin pro-
gramming the next 128-byte page.

Data will be accepted by the device as long as LD# is low
and RY/BY# is high (until the last byte of the 128-byte page
has been entered). For partial data-loads (i.e., less than
128 Bytes), LD# may be taken high (V
loading. If LD# goes high before the full 128-byte page has
been entered, the device will program the data which has
been entered to that point, and then terminate the AAI
page programming command. Any incompletely loaded
data byte (nibble) will not be programmed. The device will
signify completion of the command by driving RYBY# high.
Once RY/BY# goes high, LD# can be taken low to begin a
new AAI programming operation at a different address
location.
The RY/BY# pin will stay low while internal programming
completes. When the entire 128-byte page has been pro-
grammed, the device will return to the idle mode and the
RY/BY# pin will go high (V
has been completed.
TABLE 18: LD# Input and RY/BY# Status in
The user may terminate AAI programming by dropping the
WP#/AAI pin to TTL levels (V
and RY/BY# returns to high indicating the completion of the
AAI cycle. Software block-locking will be disabled in AAI
mode (all blocks will be write-unlocked). If AAI drops below
the Supervoltage V
LD# high), the contents of the page may be indeterminate.
