NJU3151
PRELIMINARY
4-BIT SINGLE CHIP OTP TINY CONTROLLER
s GENERAL DESCRIPTION
The NJU3151 is the C-MOS 4-bit Single Chip OTP type Micro Controller with programmable Flash Memory. It is completely compatible with the NJU3101 in function and the pin configuration. Therefore, the NJU3151 is suitable for the final evaluation before NJU3101 mask generation, the small quantity production and short leadtime. * In this data sheet, only OTP programming and the difference between NJU3151 and NJU3101 are mentioned mainly. Therefore the detail function and specification should be referred on the NJU3101 data sheet.

s Difference between NJU3151 (OTP version) and NJU3101 (MASK version)
q Operating mode One is "Normal operating mode" and the other is "OTP programming NJU3151 has two operating modes. 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).

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 256clock after RESET releasing and oscillation stability time. After information set, the program counter is set to 0000H and the NJU3151 operates in normal. [ TIMING CHART ] Oscillation Stability Time
