SEE NEW DESIGN RECOMMENDATIONS
Separately erasable blocks, including a hardware-
lockable boot block (16,384 bytes), two parameter
blocks (8,192 bytes each) and main blocks (one
block of 98,304 bytes and one block of 131,072
bytes), define the boot block flash family
architecture. See Figures 7 and 8 for memory
maps. Each block can be independently erased and

Program and Erase Automation allows program and
erase operations to be executed using an industry-
standard two-write command sequence to the CUI.
Data programming is performed in word (28F200
family) or byte (28F200 or 28F002B families)
increments. Each byte or word in the flash memory
can be programmed independently of other memory
locations, unlike erases, which erase all locations
within a block simultaneously.
The 2-Mbit SmartVoltage boot block flash memory
family is also designed with an Automatic Power
Savings (APS) feature which minimizes system
battery current drain, allowing for very low power
designs. To provide even greater power savings,
the boot block family includes a deep power-down
mode which minimizes power consumption by
turning most of the flash memory’s circuitry off. This
mode is controlled by the RP# pin and its usage is
discussed in Section 3.5, along with other power
consumption issues.
Additionally, the RP# pin provides protection
against unwanted command writes due to invalid
system bus conditions that may occur during
system reset and power-up/down sequences. For
example, when the flash memory powers-up, it
automatically defaults to the read array mode, but
during a warm system reset, where power
continues uninterrupted to the system components,
the flash memory could remain in a non-read mode,
such as erase. Consequently, the system Reset
signal should be tied to RP# to reset the memory to
normal read mode upon activation of the Reset
signal. See Section 3.6.
The 28F200 provides both byte-wide or word-wide
input/output, which is controlled by the BYTE# pin.
