EEPROM Confusion

[eds]

I have a little confusion involving the EEPROM. I have read that the memory map for the EEPROM is from $B600 to $B7FF. Then I have read some documents that describe the E2PROM (EsquaredPROM) differently than the EEPROM. It might not make sense, but I have taken the EEPROM to be internal to the chip, while the E2PROM to be an EXTERNAL EEPROM. <br>Now I have come to the point of storing code in the EEPROM. I have noticed that there is a chip in socket U1 (LP-10) and no chips inserted in the U2 or U3 socket. If the only EEPROM is a chip to insert into U2 or U3, then I do not have EEPROM at all -- correct? If so, I assume I can obtain one from nmi.<p>Thanks<p><br>----------<br>Ed Seng<p> <br>

HC11 built-in 512-byte internal eeprom, Address $B600 - $B700.<p>External eeprom is optional. It can be installed on U2 or U3 socket. You can purchase direct from NMI (214)339-2204 or at any electronic stores in your local area. Here are the part numbers,<br>8K-byte, 28C64<br>32K-byte, 28C256<br>
