Data Sheet
Auto Address Increment (AAI) Program
The AAI program instruction allows multiple bytes of data to be programmed without re-issuing the
next sequential address location. This feature decreases total programming time when the entire mem-
ory array is to be programmed. An AAI program instruction pointing to a protected memory area will be
ignored. The selected address range must be in the erased state (FFH) when initiating an AAI program
instruction.
Prior to any write operation, the Write-Enable (WREN) instruction must be executed. The AAI program
instruction is initiated by executing an 8-bit command, AFH, followed by address bits [A 23 -A 0 ]. Follow-
ing the addresses, the data is input sequentially from MSB (bit 7) to LSB (bit 0). CE# must be driven
high before the AAI program instruction is executed. The user must poll the BUSY bit in the software
status register or wait T BP for the completion of each internal self-timed Byte-Program cycle. Once the
device completes programming byte, the next sequential address may be program, enter the 8-bit
command, AFH, followed by the data to be programmed. When the last desired byte had been pro-
grammed, execute the Write-Disable (WRDI) instruction, 04H, to terminate AAI. After execution of the
WRDI command, the user must poll the Status register to ensure the device completes programming.
See Figure 8 for AAI programming sequence.
There is no wrap mode during AAI programming; once the highest unprotected memory address is
reached, the device will exit AAI operation and reset the Write-Enable-Latch bit (WEL = 0).
