µPD75336
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75336 is one of the “75X-series” 4-bit single-chip microcomputers enabled to process data with
performance equivalent to that of 8-bit microcomputers.
The µPD75336 is a microcomputer with an expanded capacity of the ROM and RAM of conventional µPD75328
and an improved 8-bit data processing capacity. It can carry out A/D converter low-voltage operations.
For evaluation purposes for system development or small-quantity production, the µPD75P336 is available which
is a product with the on-chip mask ROM of µPD75336 replaced with a one-time PROM.
Functions are described in detail in the following User’s Manual, which should be read when carrying out design
work.
µPD75336 User’s Manual: IEU-725
