JRC NJU3151M, NJU3151D Datasheet

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.

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
