Hello, everyone,

We met with a problem about the connection between the chip and DAS. The chip we use is XC2224L, VQFN package. DAP connector of DAP miniwiggler. The schematic refers to the Easy Kit XC2XXX. The DAS can not recognize the chip. Memtool 4.4 was also tested but failed.

Already connect 'TDO_A' to 470R then GND and '/TRST' to 2.74K to +5V.

While connecting, 'RESET' is high. '/PORST' is high.

Do you have any idea about that?

Thanks. Show Less

I'm trying to write a short code for TC1796 CPU but I've faced an issue. 
When I use the following assembler code everything works fine:

call 0x800xxxxx
ret

But the following code does not work and I have no clue why:
movh.a a15, #High
lea a15, [a15]Low
nop // tried without this instruction also
calli a15 // crushed
ret

I hope that Infineon engineers can shed light on this problem. When I replace calli to call(only this single instruction) the code works just fine. So I believe the problem with "CALLI" instruction.

Hi~

 

Im wondering whether CY96610 Series( ex : CY96F612RBPMC-GS-UJE1) has ASIL  rating or not.

Also, Im looking for whether it has HSM in it or not.

Many thanks

Hi Infineon.

 

MB9B110T and CY9B100A have min and max value of smoothing capacitor in recommended operating conditions.

(Min value is 1uF and max value 10uF.)

Please confirm recommended operating conditions of below link.

 

MB9B110T DS:

CY9B100A DS:

But, there is no description of min and max value of smoothing capacitor in MB9B160R(CY9BF166NPMC-GNE2) datasheet.

Please confirm recommended operating conditions of below link.

Could you please let us know min and max value of smoothing capacitor for MB9B160R(CY9BF166NPMC-GNE2)?

 

 

Best Regards.
