Quad Page Program (QPP 32h or 38h, or 4QPP 34h)
The Quad-input Page Program (QPP) command allows bytes to be programmed in the memory (changing
bits from 1 to 0). The Quad-input Page Program (QPP) command allows up to a page size (512 bytes) of data
to be loaded into the Page Buffer using four signals: IO0-IO3. QPP can improve performance for PROM
Programmer and applications that have slower clock speeds (< 12 MHz) by loading 4 bits of data per clock
cycle. Systems with faster clock speeds do not realize as much benefit for the QPP command since the
inherent page program time becomes greater than the time it takes to clock-in the data. The maximum
frequency for the QPP command is 80 MHz.
To use Quad Page Program the Quad Enable Bit in the Configuration Register must be set (QUAD=1). A
Write Enable command must be executed before the device will accept the QPP command (Status Register-
1, WEL=1).
The instruction
 32h (ExtAdd=0) is followed by a 3-byte address (A23-A0) or
 32h (ExtAdd=1) is followed by a 4-byte address (A31-A0) or
 38h (ExtAdd=0) is followed by a 3-byte address (A23-A0) or
 38h (ExtAdd=1) is followed by a 4-byte address (A31-A0) or
 34h is followed by a 4-byte address (A31-A0)
and at least one data byte, into the IO signals. Data must be programmed at previously erased (FFh) memory
locations.
QPP requires programming to be done one full page at a time. While less than a full page of data may be
loaded for programming, the entire page is considered programmed, any locations not filled with data will be
left as ones, the same page must not be programmed more than once.
All other functions of QPP are identical to Page Program. The QPP command sequence is shown in the
figure below.
