4-BIT SINGLE CHIP OTP MICRO CONTROLLER
PACKAGE OUTLINE
GENERAL DESCRIPTION
■
NJU3553
The
is the C-MOS 4-bit Single Chip OT P type
Micro Controller with programmable Flash Memory.
It is completely compatible with the
and the pin configuration. Therefore, the

generation, the small quantity production and short leadtime.
* In this data sheet, only OTP programming and the
difference between NJU3553 and NJU3503 are
mentioned mainly.
Therefore the detail function and specification should
be referred on the NJU3503 data sheet.
