4-BIT SINGLE CHIP OTP MICRO CONTROLLER
PACKAGE OUTLINE
GENERAL DESCRIPTION
■
NJU3555
The
is the C-MOS 4-bit Single Chip OT P type
Micro Controller with programmable Flash Memory.
It is completely compatible with the

generation, the small quantity production and short leadtime.
* In this data sheet, only OTP programming and the
difference between NJU3555 and NJU3505 are
mentioned mainly.
Therefore the detail function and specification should
be referred on the NJU3505 data sheet.
