AUTOMOTIVE 87C51FA/FB/FC/FC-20
range of - 40
°C to + 85C ambient. For the automo-
tive temperature range option, operational charac-
teristics are guaranteed over the temperature range
of - 40
C to + 125C 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
I/O 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.
