EPROMs – 21
CHAPTER 3 EPROMs
DESCRIPTION
Before you can save and boot your application from the 4010, you
must first configure the system for your particular application
requirements.
SSD1
SSD1 generally contains the program to be executed on power–up.
The program is automatically loaded into DOS memory and
executed. SSD1 accepts either 128K/512K, 5V only, flash memory.
Your application program can be saved to the flash memory using
the on–card programmer. These devices are erased automatically
during the programming process. You can write to the flash
memory a limited number of times (about 100,000), if your applica-
tion program requires changes. You can also use a 512K/1 MB
standard EPROM. These EPROMs must be programmed with an
off–card programmer. Please refer to Appendix B for more infor-
mation.
