8-MBIT SmartVoltage BOOT BLOCK FLASH MEMORY FAMILY
1.4
Pinouts
Intel’s SmartVoltage Boot Block
architecture provides pinout upgrade paths
to the 8-Mbit density. 8-Mbit pinouts are
given on the chip illustration in the center,
with 2-Mbit and 4-Mbit pinouts going
outward from the center for reference.
The 28F008B 40-lead TSOP pinout for
space-constrained designs is shown in
Figure 1. For designs that require x16
operation but have space concerns, refer to
the 48-lead pinout in Figure 3. The 28F800
44-lead PSOP pinout follows the industry-
standard ROM/EPROM pinout, as shown in
Figure 2.
