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:
– Port 0 (P0.0-P0.7, external address/data bus
AD0-AD7)
– Port 2 (P2.0-P2.3, external address bus A8-
A11)
– Port A (PA0-PA7)
– Port D (PD2)
– Bus control signal (RD,WR,PSEN,ALE)
Pin 5 requires a pull-up resistor (2kΩ for 3V
devices, 7.5kΩ for 5V devices) for all devices.
