I have a design in which I am using an STM32L152VDT6 processor. The first prototype boards arrived, and one of the first things I noticed was that there was a resistance of 120 ohms between VCC and GND. I knew something had to be wrong at that point....

We have made good progress in migrating from an ST90R158 (ROMLESS) processor to an ST158E158 (EPROM). The issue we are now facing is that the code that is running in the ST90E will not run in the ST90T (will not even try to boot), which is our ultima...

We are currently trying to migrate a design from the ST90R to the ST90T (for supply reasons). We have been successful in reconfiguring the start vector in the ST90T to allow us to run from external ROM using the code developed for the ST90R. Unfortun...

Hi, Tesla, Peter,Yes. We managed to secure a STM32V8T6 part and have confirmed that the parts from the broker are bogus. Thank you for the links as I was going to inquire about Xrays. I really appreciate your responses!Thank youMark

Hi, Tesla,Thanks for your reply. I am including pictures of the chip on the board. A recent development may be of interest. I could not get more of the STM32L152VDT6 parts, but we did manage to secure a couple STM32L152V8T6 parts. I ohmed these parts...

Hi,thank you for your reply. We are orienting the chip with Pin 1 at the dimple on the top of the chip and are counting pins counter-clockwise. We are using this pinout:

STM32L152VDT6 extreme current draw on power-up

Differences in ST90T158 and ST90E158

Question regarding migration from the ST90R to ST90T.

Does anyone know of a supply source for the old ST90R158Q6 processor?

Does anyone have a copy of these files? They were mentioned in a post for an obsolete part, the ST90R158; but the links are broken. http://www.stmcu.com/mcdfiles/7241.pdf http://www.stmcu.com/mcdfiles/7620.pdf

Re: There is an old question regarding the use of ST90R158 (ROMless) code in an ST90T158 (OTP) processor. I need some information on a way to accomplish this, if possible.
