NJU3554 PRELIMINARY 4-BIT SINGLE CHIP OTP MICRO CONTROLLER s GENERAL DESCRIPTION The NJU3554 is the C-MOS 4-bit Single Chip OTP type Micro Controller with programmable Flash Memory. It is completely compatible with the NJU3504 in function and the pin configuration. Therefore, the NJU3554 is suitable for the final evaluation before NJU3504 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.

Non connect anything to the other terminals. s Difference between NJU3554 (OTP version) and NJU3504 (MASK version) q Operating mode NJU3554 has two operating modes. One is ”Normal operating mode” and the other is “OTP programming mode”. • Normal operating mode The ”TEST” terminal is set to low level. (The terminal is recommended to connect to GND.) Operating voltage range; 2.7V ~ 5.5V. OTP Programming mode User program is read out from or written into the OTP by the universal programmer “SUPERPRO/L” and converting adapter made by XELTEK co,.(USA). Reset Terminal Type Internal Pull-up Resistance NJU3554 With Pull-up NJU3504 Without Pull-up • q q Option information set in the initialization When the initialization is performed(RESET terminal is “L”), the operation information stored in option area is set as shown in the following timing chart . The option information is set in the term of 1 / fOSC x 512clock after RESET releasing and oscillation stability time. After information set, the program counter is set to 0000H and the NJU3554 operates in normal.
