Conclusion

  • There is no life left for the 1M Flash chips.
  • The 512K size was the most cost effective and when the 64 sector version was 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.
