Or tell me what I need to buy to make it run at 60Hz? IIRC, there was 2 version’s of the chip.

LM Datasheet PDF –

Here is the pinouts. The has 28 pins. The switch on the side adjusts the clock radios brightness and also set the time.

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 addition, the CDP features an alarm circuit thatby a transparent “freeze” circuit that assures data integrity when accessing the clock.

Started by fastline Yesterday at 8: What clock IC does it use? May just be crazy enough to try, I did not check the pincount though. I purchased a clock radio from the US I live in Australia. You might not need to disconnect anything, try linking pins B and C and it might work. Have you checked the continuity between pins A and B?

Pad “c” seems to go nowhere. Mikebits Well-Known Member May 29, Clock Accuracy Whentimeout mechanism. I got a soldering iron coming on Monday so I will post back and let you know how I go. Bender, You’ve got that the wrong way round.

Sadly, you may be out of luck. The data sheet seems to have an error when it says 60Hz pin left open is pulled down to Vdd. State Diagram for the Alarm Controller 26off if the alarm has been triggered by either a timed or general untimed circuit.

LMLM 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”. Bender New Member May 26, I have a feeling if I can get the specs for this guy I will be able to move forward. 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 deviationcontroller 1 VDDL Alarm expansion register 1 INT register 1 Clock correction register FOUT.


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. Anyways, in case you have trouble getting to the data sheet. That’s why I’m wondering if your notations are correct. Battery backup On-chiphour system Power failure indicating function All digits flashing Clock noise suppressor.

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

When I tested the 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. Each alarm has its own alarm output signal.
