1 4 Pinouts
The 28F200BX 44-Lead PSOP pinout follows the in-
dustry standard ROM EPROM pinout as shown in
Figure 3 with an upgrade to the 28F400BX (4-Mbit
flash family) Furthermore the 28F200BX 56-Lead
TSOP pinout shown in Figure 4 provides density up-
grades to the 28F400BX and to future higher density
boot block memories
28F400BX
The 28F002BX 40-Lead TSOP pinout shown in Fig-
ure 5 is 100% compatible and provides a density
upgrade to the 28F004BX 4-Mbit Boot Block flash
memory

The 28F200BX-T device has the 16-Kbyte boot
block located from 1E000H to 1FFFFH to accommo-
date those microprocessors that boot from the top
of the address map In the 28F200BX-T the first
8-Kbyte parameter block resides in memory space
from 1D000H to 1DFFFH The second 8-Kbyte pa-
rameter block resides in memory space from
1C000H to 1CFFFH The 96-Kbyte main block re-
sides in memory space from 10000H to 1BFFFH
The 128-Kbyte main block resides in memory space
from 00000H to 0FFFFH as shown in Figure 8
