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 lead-
time.
*
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.

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).

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 / f
OSC
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.
