PRELIMINARY
4-BIT SINGLE CHIP OTP MICRO CONTROLLER
s GENERAL DESCRIPTION
The NJU3553 is the C-MOS 4-bit Single Chip OTP type
Micro Controller with programmable Flash Memory.
It is completely compatible with the NJU3503 in function
and the pin configuration. Therefore, the NJU3553 is
suitable for the final evaluation before NJU3503 mask
generation, the small quantity production and short lead-
time.
* 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.
