NJU3151
PRELIMINARY
4-BIT SINGLE CHIP OTP TINY CONTROLLER
■ PACKAGE OUTLINE
■ 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.

■ Difference between NJU3151 (OTP version) and NJU3101 (MASK version)
●
Operating mode
NJU3151 has two operating modes.
mode”.
●
One is ”Normal operating mode” and the other is “OTP programming
•
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.
