PD75P336
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
µ
PD75P336 is a version of the
µ
PD75336 in which the on-chip mask ROM is replaced by one-time
PROM.
As the
µ
PD75P336 is user-programmable, it is suitable for preproduction in system development, and for
short-run and multiple device-production.
Detailed function description, etc. are described in the following User's manual. Be sure to read it when
designing.
