NJU3151
4-BIT SINGLE CHIP OTP TINY CONTROLLER
GENERAL DESCRIPTION
■
NJU3151
The
Micro Controller with programmable Flash Memory.
It is completely compatible with the
and the pin configuration. Therefore, the
suitable for the final evaluation before
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)
■
NJU3151
●
Operating mode
NJU3151
has two operating modes. One is ” Normal operating m ode” 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).
●
Option information set in the initialization
When the initialization is perf orm ed(RESET ter m inal is “L” ), the operation inf orm ation stor ed in option area is
OSC
set as shown in the following timing chart . The option information is set in the term of
1 / f
x 256clock
RESET releasing and oscillation stability time. After information set, the program counter is set to 0000H and
NJU3151
the
operates in normal.
