µPD75P308
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75P308 is a model of the µPD75308 equipped with a one-time PROM or EPROM instead of an
internal mask ROM.
Two types are available as the µPD75P308. The one-time PROM type is ideal for production of a small
quantity of many different types of application systems as data can only be written once to the one-time
PROM of this type. Programs can be written and rewritten to the built-in EPROM type making it ideal
for system evaluation.
Detailed functions are described in the followig user's manual. Be sure to read it for designing.
µPD75308 User's Manual: IEM-5016

To connect the crystal/ceramic oscillator to the main
system clock generator.
— When inputting the external clock, input the external
clock to pin X1, and the reverse phase of the
external clock to pin X2.
To connect the crystal oscillator to the subsystem
— clock generator.
When the external clock is used, in XT1 inputs the
external clock. In this case, pin XT2 must be left
— open.
Pin XT1 can be used as a 1-bit input (test) pin.
— System reset input (low level active)
