Notice: This is not a final specification.
Some parametric limits are subject to change.
BUILT-IN PROM VERSION
In addition to the mask ROM versions, the 4583 Group has the
One Time PROM versions whose PROMs can only be written to
and not be erased.
The built-in PROM version has functions similar to those of the
mask ROM versions, but it has PROM mode that enables writing to
built-in PROM.
Table 21 shows the product of built-in PROM version. Figure 69
shows the pin configurations of built-in PROM versions.
The One Time PROM version has pin-compatibility with the mask
ROM version.
