Question regarding migration from the ST90R to ST90T.

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, We are storing some values to Emulated EEPROM using on-chip Flash memory. It was working fine for few months suddenly its reading nothing from the memory. Then we downloaded the same firmware again and its started to work. Why its happened?

VNQ5E160AK 1) current sense limits 2) internal power limitation

Hi, I'm using some VNQ5E160AK with current monitoring. According to datasheet Iout/Isense ratio is in the range of 465 for 'high' current, means it should be 6.5mA for 3A and 21.5mA for 10A. As my ADC range is 5V, I load sense pin with a 200 Ohm resi...

ADC request DMA transfer

Hello,we are using STR73x device. Our application needs to get 1 ADC sample every 5 ms and uses DMA to transfer that to memory.to do this, we setup a TB1 timer to trigger every 5 ms.On TB1 interrupt, we start a single shot ADC conversion.This works ...

I am using MC peripheral part# ZPSD301B-90JI in one of my applications. This part is obsolete and no longer supported by ST. I want to know if I can get any information on how to program a fresh MC. Can I do it with PSDsoft? What hardware is needed

I have BK Precision 864 universal programmer. Can I use it to flash this MC? Or please let me know what hardware (cables, prorammer hardware etc) is needed if I use PSDSoft software.

What is the gate length and channel length of POWER MOSFET?

I want to know the gate length and channel ​length of STF23N80K5 and STF26N60M2?This is for neutron affect analysis in space environment.

Does any one know the difference between M29F040B-70K6 and M29F040B-70K6F?

I cannot find any data on these and the part is obsoleteThanks George

VNI8200XP - outputs switching sporadically at power-up and power-down

Hello. I'm designing a new board where I use VNI8200XP to control some LEDs and relay loads.In my case VNI is used in SPI mode (SEL2 pulled high to Vreg), internal DC/DC converter is disabled and Vreg is supplied from on-board +24V/+5V DC/DC Converte...
