EXPLANATION OF AC SYMBOLS
In an effort to remain compatible with the original 8051 family, the DS87C520 and DS83C520 specify
the same parameters as such devices, using the same symbols. For completeness, the following is an
explanation of the symbols.

Note 1:
Startup time for crystals varies with load capacitance and manufacturer. Time shown is for an 11.0592MHz crystal
manufactured by Fox.
Reset delay is a synchronous counter of crystal oscillations after crystal startup. Counting begins when the level
on the XTAL1 pin meets the V
IH2
criteria. At 33MHz, this time is 1.99ms.
