REVISION HISTORY
This data sheet replaces the following data sheets
ERRATA
An A or B step 80C186XL 80C188XL has the follow-
ing errata The A or B step 80C186XL 80C188XL
can be identified by the presence of an ‘‘A’’ or ‘‘B’’
alpha character respectively next to the FPO num-

1 An internal condition with the interrupt controller
The C step 80C186XL 80C188XL has no known er-
rata The C step can be identified by the presence of
a ‘‘C’’ or ‘‘D’’ alpha character next to the FPO num-
ber The FPO number location is shown in Figure 4
PRODUCT IDENTIFICATION
Intel 80C186XL devices are marked with a 9-charac-
ter alphanumeric Intel FPO number underneath the
product number This data sheet (272431-001) is
valid for devices with an ‘‘A’’ ‘‘B’’ ‘‘C’’ or ‘‘D’’ as
the ninth character in the FPO number as illustrated
in Figure 4
can cause no acknowledge cycle on the INTA1
line in response to INT1 This errata only occurs
when Interrupt 1 is configured in cascade mode
and a higher priority interrupt exists This errata
will not occur consistently it is dependent on in-
terrupt timing
