B is connected to many other points. LMLM On the back of the clock radio there is a place where it looks like a switch should be to allow me to change between 50 and 60 Hz. By continuing to use this site, you are consenting to our use of cookies. I would suggest that you don’t mess around with shorting any of the IC pins, just connect pins B and C on the PCB, which are connected to the relevant pins.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Or tell me what I need to buy to make it run at 60Hz?

I cannot remember the IC id most of those old clock radio’s used. When I tested daatasheet Hz going through the clock radio with a multimeter is only comes up with 50Hz Point C on the below image. I went ahead and checked the pinout. LM with led clock Abstract: Welcome to our site! Also, for 50Hz, I think you want to tie pin 26 to ground Vssnot power pin. Activating VSS using two inputs simultaneously alarm select and sleep selectthe.


Thanks for all the information you have provided with regards to my issue. State Diagram for the Alarm Controller 26off if the alarm has been triggered lj8363 either a timed or general untimed circuit.

I think km8363 TMS part looks similar as the chip that Hero identified.

I got a soldering iron ml8363 on Monday so I will post back and let you know how I go. It would be nice to see the other side of datasheer little board. I found 2 chips one on the radio and the other just behind the display of the clock. It would be great if I could put it to some use. Hero Banned May 29, I think you should leave pin 25 alone.

The manual of the radio states that it should be running at V 60Hz. Sadly, you may be out of luck. A “1” in bit-7 will identify the alarm circuit.

Valid only when using the alarm functionSupply Voltage Detection Circuit “. Thread starter Bender Start date May 26, You must log in or register to reply here. Hero Banned May 30, Is it possible you miscounted the pins? I found a datasheet for a TMS 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.

What clock IC does it use? Here is the back of the PCB, sorry for the low res image, I took it from my mobile phone. Previous 1 2 May just be crazy enough to try, I did not check the pincount though.

Articles Top Articles Search datasneet. Hero Banned May 28, ddatasheet You might not need to disconnect anything, try linking pins B and C and it might work. For one alarm output, DC output signal is provided. For a better experience, please enable JavaScript in your browser before proceeding.

Upon opening the baby up and taking a quick look around it would appear that there is something missing on the PCB board that should link point A and Point B to convert the 50Hz to 60Hz. No abstract text available Text: Pad “c” seems to go nowhere. Clock Accuracy Whentimeout mechanism.

However, what is missing is most likely a slide switch that datqsheet have pin “b” as a common point. The data sheet seems to have an error when it says 60Hz pin left open is pulled down to Vdd.

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”. Just saying hello Started by MichaelaJoy Yesterday at 6: I’m assuming now all I need now is short the power to pin 25 or 26 and test it out. Bender, You’ve got that the wrong way round.

Each alarm has its own alarm output signal. I then purchased a step down converter so it would work and it does just fine however the time is out by 10 seconds.
