C EEPROM Devices
If none of the built-in scripts is suitable e.g., due to a different type of NAND-Flash or
a different memory organization or anything not matching the internal boot scripts, an
external serial boot EEPROM is required. Depending on the application
characteristics, this can be a small (1 Kilobyte or less) EEPROM that contains a small
boot script and starts the PNX17xx Series system in host-assisted mode or boot from
Flash memory or ROM devices. Alternately, a large serial EEPROM can be used to
contain a complete disk file system or an upload capability from another device than
Flash/ROM.
For a 2-Kilobyte or smaller EEPROM, the script must start at byte address 1 (not 0).
For a 4-Kilobyte or larger EEPROM, the boot script must start at byte address 0. More

word value (the byte read first ends up as the least significant byte, LBS). The 32-bit
words are then interpreted as commands, as documented earlier in
Remark: It has been seen that depending on the Write Protect pin status, some
EEPROMs do not behave the same way on a write of 0 bytes
internal counter gets or does not get incremented which makes this rule of where the
first byte is located at address 0 or 1 different. Refer to EEPROM datasheet or try both
options.
The PNX17xx Series Boot module supports all I
wire EEPROMs) that use a 1-byte or 2-byte address protocol and respond to an I
device code 1010 (binary). Subtle differences exist between devices For example:

It is recommended to avoid devices that have partial array write protection, since
such devices could be overwritten by accidental or intentional I
boot failure during the next reset.
Some devices may have additional functionality that is useful, like a watchdog
timer or a power voltage drop sensor.
Availability from different vendors may vary.
Programming protocols may vary.
