Pin Description
4.1
VCC
Supply voltage.
4.2
GND
Ground.
4.3
Port 1
Port 1 is an 8-bit bi-directional I/O port. Port pins P1.2 to P1.7 provide internal pull-ups. P1.0 and
P1.1 require external pull-ups. P1.0 and P1.1 also serve as the positive input (AIN0) and the
negative input (AIN1), respectively, of the on-chip precision analog comparator. The Port 1 out-
put buffers can sink 20 mA and can drive LED displays directly. When 1s are written to Port 1
pins, they can be used as inputs. When pins P1.2 to P1.7 are used as inputs and are externally
pulled low, they will source current (I
IL) because of the internal pull-ups.
Port 1 also receives code data during Flash programming and verification.
4.4
Port 3
Port 3 pins P3.0 to P3.5, P3.7 are seven bi-directional I/O pins with internal pull-ups.
P3.6 is hard-wired as an input to the output of the on-chip comparator and is not accessible as a
general-purpose I/O pin. The Port 3 output buffers can sink 20 mA. When 1s are written to Port
3 pins they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 3
pins that are externally being pulled low will source current (I
IL) because of the pull-ups.
Port 3 also serves the functions of various special features of the AT89S2051/S4051 as listed
below:
Port 3 also receives some control signals for Flash programming and verification.
