DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD75P238  
4-BIT SINGLE CHIP MICROCOMPUTER  
DESCRIPTION  
The µPD75P238 is a version of the µPD75238 in which the on-chip mask ROM is replaced by one-time PROM or  
EPROM.  
The one-time PROM version can be written to once only, and is useful for short-run and multiple device-  
production of sets and early start-up. Also, the EPROM version allows programs to be written and rewritten, and  
is thus ideal for system evaluation.  
Functions are described in detail in the following User's Manual, which should be read when carrying out design  
work.  
µPD75238 User's Manual : IEU-731  
The µPD75P238 EPROM product does not provide a level of reliability suitable for use as a volume  
production product for users' devices. The EPROM product should be used solely for function evaluation  
in experiments of preproduction.  
FEATURES  
o µPD75238 pin compatible  
o On-chip PROM: 32640 × 8  
o On-chip RAM: 1024 × 4  
o High-voltage display outputs  
. S0 to S8 & T0 to T9  
: Internal pull-down resistors  
. S9, S16 to S23 & T10 to T15: Open-drain  
o Drive capability in same supply voltage range as mask version µPD75238 (2.7 to 6.0 V)  
o Ports 4 & 5: No pull-up resistor  
o Port 7: No pull-down resistor  
Note No internal pull-up and pull-down resistor function by mask option.  
USE  
VCR, Audio-visual, ECR, Microwave oven
