4-BIT SINGLE CHIP OTP MICRO CONTROLLER

PACKAGE OUTLINE

GENERAL DESCRIPTION

■

NJU3554

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

mask generation, the small quantity production and short leadtime.

* In this data sheet, only OTP programming and the

difference between NJU3554 and NJU3504 are

mentioned mainly. Therefore the detail function and specification should be referred on the NJU3504 data sheet.
