1.3 Applications
The 4-Mbit boot block flash memory family com-
bines high density, high performance, cost-effective
flash memories with blocking and hardware protec-
tion capabilities. Its flexibility and versatility will re-
duce costs throughout the product life cycle. Flash
memory is ideal for Just-In-Time production flow, re-
ducing system inventory and costs, and eliminating
component handling during the production phase.
During the product life cycle, when code updates or
feature enhancements become necessary, flash
memory will reduce the update costs by allowing ei-
ther a user-performed code change via floppy disk
or a remote code change via a serial link. The 4-Mbit
boot block flash memory family provides full func-
tion, blocked flash memories suitable for a wide
range of applications. These applications include
Extended PC BIOS and ROM-able
applications
storage, Digital Cellular Phone program and data
storage,
Telecommunication
boot/firmware,
Print-
er
firmware/font storage and various other embed-
ded applications where both program and data stor-
age are required.
Reprogrammable systems such as personal com-
puters, are ideal applications for the 4-Mbit flash
memory products. Portable and handheld personal
computer applications are becoming more complex
with the addition of power management software to
take advantage of the latest microprocessor tech-
nology, the availability of ROM-based application
software, pen tablet code for electronic hand writing,
and diagnostic code. Figure 1 shows an example of
a 28F400BX-T application.
This increase in software sophistication augments
the probability that a code update will be required
after the PC is shipped. The 4-Mbit flash memory
products provide an inexpensive update solution for
the notebook and handheld personal computers
while extending their product lifetime. Furthermore,
the 4-Mbit flash memory products’ power-down
mode provides added flexibility for these battery-
operated portable designs which require operation
at very low power levels.
The 4-Mbit flash memory products also provide ex-
cellent design solutions for Digital Cellular Phone
and Telecommunication switching applications re-
quiring high performance, high density storage capa-
bility coupled with modular software designs, and a
small form factor package (X8-only bus). The
4-Mbit’s blocking scheme allows for an easy seg-
mentation of the embedded code with; 16 Kbytes of
Hardware-Protected Boot code, 4 Main Blocks of
program code and 2 Parameter Blocks of 8 Kbytes
each for frequently updatable data storage and diag-
nostic messages (e.g., phone numbers, authoriza-
tion codes). Figure 2 is an example of such an appli-
cation with the 28F004BX-T.
These are a few actual examples of the wide range
of applications for the 4-Mbit Boot Block flash mem-
ory family which enable system designers achieve
the best possible product design. Only your imagina-
tion limits the applicability of such a versatile product
family.
