1M
The following device was available 27/07/2013
| Device | Package | Manufacturer | Sectors | ||
|---|---|---|---|---|---|
 | AM29F800BB-55EF | 48-Pin TSOP | SPANSION | 64 Kbyte sectors |
Spansion are putting their 1M AMD Flash chips on End of Life EOL.
AMIC may have had some 5v replacements A29800, A29801 these are no longer available.
The package is slightly larger, they do not fully match.
Once stocks of the Am29F080B device are depleted, there is no replacement.
512K Flash 5v
The following devices have been available from 31/08/17
NOTE: Using these chips with the Z88.
Mechanically and electrically, these chips are the same as before. The software required to use them need to be updated.
Implemented
- OZ 4.7.1.
Outstanding
- Romcombiner v2.10
- Romupdate
- Flashstore v1.9.3
- Eazylink2 v5.2.3
- FlashTest v1.4.2 (zprom)
The chip may also be programmed with an external programmer.

NOTE: The Z88
- will only be able to use these chips as a ROM. (Needs to be tested - Parts on order).
- will not be able to program this chip initially, due to the change from 64Kbyte to 4 Kbyte sectors.
- may be able to program the chip if additional software is written.
The chip may be programmed with an external programmer.

Conclusion
- There is no life left for the 1M Flash chips.
- The 512K size was the most cost effective when the 64 sector versions were manufactured by two companies.
- Microchip are now the only company left making 5v Flash.
- 128K is not a lot cheaper than the 512K and is uneconomic to use.
