4-BIT SINGLE CHIP OTP TINY CONTROLLER
s GENERAL DESCRIPTION
The NJU3152 is the C-MOS 4-bit Single Chip OTP type Micro Controller with programmable Flash Memory. It is completely compatible with the NJU3102 in function and the pin configuration. Therefore, the NJU3152 is suitable for the final evaluation before NJU3102 mask generation, the small quantity production and short leadtime. * In this data sheet, only OTP programming and the difference between NJU3152 and NJU3102 are mentioned mainly. Therefore the detail function and specification should be referred on the NJU3102 data sheet.
