April 22, Security bit 1 stops movc from the sector in which it is set, bit 2 stops erase and program, bit 3 makes device useless for ISP. Does not look fool proof. If the current exceeds 2A, please check for circuit fault. April 14, This is how I found out that it is not working with FM 5. Do not turn on the power supply until all connections are completed.

May 06, Fortunately all seems OK. Here is the debug file. Note that you can only see posts made in areas you currently have access to.

And that takes of a part of useful code. Sorry if I have missed in the datasheet or Adtasheet Manual. From where can one download older versions of Flashmagic? I could not see any readable ,pc936 in notepad. Products are not authorized for use in such applications unless Integrated Silicon Solution, Inc. Sometimes you may need more than 1 attempt. Please login or register. Nothing happens when I run. I had to power up twice to read device ID. So if I had to do it twice, it was normal.


Problem vanished in version 5. If someone uses the last sector, I can see problems. March 23, I have been using RD2 for years now.

Boot loader version is 7. So it is obviously not text.

This section allows you to view all posts made by this member. As per Flashmagic there are 32 Blocks. This is true for all the versions I have used so far. The bits do not get set and the micro resets. Actually later I realized that I can select only 8 out of 32 for LPC, perhaps the list is for upto any 64K device for future. IS31BLB features an over voltage shutdown pin which prevents the output voltage from exceeding 35V typ.

The software will not work. May 15, ISSI assumes no liability arising out of the application or use of any information, products or services described herein. As per data sheet there are 8 nos 2K sectors. April 11, I am setting bit1’s for all sectors, cannot use bit 0.


There are 32 intensity levels with the lowest set as the power on default.

This is the only way to verify that serial number is set. The internal feedback regulation point is 0.

LPC936 Brownout issues

And there is no way to stop this. If not, please do. Each sector has 3 security bits assigned to it. The device regulates the LED load current is set using an external, low value sensing resistor.

Normally it gets into programming mode in one go. Is this logic OK?

This means that anyone can read the code. Actually they are bits 0 to 2, I had also made the same mistake. Integrated Silicon Solution, Inc. February 17, ,
