When developing a system that will ultimately utilize a
ROM-based microcontroller (MCU), it is still typical to
make use of an EPROM-based MCU during the final
stages of the design. Initial development may also
include the use of some type of emulator system, but
prototype units normally make use of a windowed
EPROM or OTP EPROM MCU, and the design is opti-mized/validated based upon the performance of the
EPROM-based device without, in many cases, taking
into consideration potential differences in the perfor-mance of the ROM-based device that will ultimately be
used.
