52 PIN PACKAGE I/O PORT
The 52-pin package members of the uPSD321X
Devices have the same port pins as those of the
80-pin package except:
s Port 0 (P0.0-P0.7, external address/data bus
AD0-AD7)
s Port 2 (P2.0-P2.3, external address bus A8-
A11)
s Port A (PA0-PA7)
s Port D (PD2)
s Bus control signal (RD,WR,PSEN,ALE)
Pin 5 requires a pull-up resistor (2kΩ for 3V de-
vices, 7.5kΩ for 5V devices) for all devices.
