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
suitable for the final evaluation before

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.
