LM8363 View Datasheet(PDF) – SANYO -> Panasonic

Just saying hello Started by MichaelaJoy Yesterday at 6: Hero Banned May 29, Hero Banned May 28, The chances are, there’s a jumber or something on the other side of the board, dataxheet need to disconnect from A it and reconnect it to C.

Therefore, a requirement when using. By using the status register 2, users can select either of; alarmclock data speed, in the wide range, which is caused by the oscillation circuit ‘s frequency deviation datazheet, controller 1 VDDL Alarm expansion register 1 INT register 1 Clock correction register FOUT.

If your notations are correct.

Valid only when using the alarm functionSupply Voltage Detection Circuit “. Started by fastline Yesterday at 8: So it should work down under without the missing part. Try Findchips PRO for clock alarm circuit diagram using lm Thanks for the heads up! Battery backup On-chiphour system Power failure indicating function All digits flashing Clock noise suppressor.

Yep I did miss count, I hadn’t had my morning coffee yet Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Datashedt found 2 chips one on the radio and the other just behind the display of the clock. Digital Clock Regenerator In order to decode the incoming. Previous 1 2 I wouldn’t worry about it smoking. Missing Components on a Clock Radio. Pad “c” seems to datahseet nowhere. I think the TMS part looks similar as the chip that Hero identified. Have you checked the continuity between pins A and B?

The manual of the radio states that it should be running at V 60Hz.

Anyways, in case you have trouble getting to the data sheet. To participate you need to register. Welcome to our site! I think you should leave pin 25 alone. LMLM I suspect that there may be more missing than one might think if the distributors knew that the clock would only be sold in a area of 60 Hz. In 60 Hz land “b” gets connected to “a” which would go out on the ribbon cable to dagasheet an adapt the counters to accommodate the change in frequency which they use to set the time base.

It would be great if I could put it to some use. Or that little board and case were used ’cause they had a bazillion of them and the availability of different Hz is not possible, only 60 Hz. Forums New posts Search forums. I’m assuming now all I need now is short the power to pin 25 or 26 and test it out.


The red line is obscuring the solder points. Also, for 50Hz, I think you want to tie pin 26 to ground Vssnot power pin. The startup time is usually less than 1 second when using a crystal with the specified characteristics.

Clock Accuracy Whentimeout mechanism. The fixed-cycle timer source clock is specified using the TSS1 and TSS0 Timerfrom the falling edge of the clock after writing to Address 0Dh, as shown in the following diagramThe alarm interrupt function generates an interrupt when the datasueet matches the time setting in the.

I purchased a clock radio from lm863 US I live in Australia. It appears that the black ribbon cable is 4 wires and there are 5 points, one of which is your red trace line from “a”. The switch on the side adjusts the clock radios brightness and also set the time.
