AUTOMOTIVE 87C51FAFBFCFC-20
range of b40 Cto a85 C ambient For the automo-
tive temperature range option operational charac-
teristics are guaranteed over the temperature range
of b40 Cto a125 C ambient The automotive ex-
tended and commercial temperature versions of the
MCS-51 product families are available with or with-
out burn-in options
As shown in Figure 2 temperature burn-in and
package options are identified by a one- or two-letter
prefix to the part number
PIN DESCRIPTIONS
VCC Supply voltage
VSS Circuit ground
VSS1 Secondary ground (in PLCC only) Provided to
reduce ground bounce and improve power supply
by-passing
NOTE
This pin is NOT a substitute for VSS pin (pin 22)
Port 0
Port 0 is an 8-bit open drain bidirectional
IO port As an output port each pin can sink several
LS TTL inputs Port 0 pins that have 1’s written to
them float and in that state can be used as high-im-
pedance inputs
270961 – 2
Example
