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 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.
