Hello all. Tell me how to find (choose) any chip with which you can replace the AT32UC3L064 (TQFP48)? I have made speech recognition on this microcontroller. How to find a worthy replacement. In terms of performance, power consumption and pin-compatible?

Pin compatible may be a stretch, but you could use (eg) Digikeys search to find other 48 pin parts, with some MHz margin over what you have now.

 

eg ATSAM4N8AA-MUR pops up, as a 48 pin with 512kF and 100MHz.

    LPC51U68JBD48E is 48 pins, 100MHz and 256kF

    ATSAM4S2AB-AN is 48 pins, 120Mhz

    STM32G431CBT6 is 48 pins, 170MHz ...

The lesser program space UC3L went EOL effective 9-Mar'17.

The recommended replacement for UC3L064 is UC3L0128.

An alternative is SAM L11 though not pin compatible.

 

Product Change Notification - KSRA-07AWFR880 - 09 Mar 2017 - End of Life (EOL) of AT32UC3L016, AT32UC3L032 and AT32UC3L064 Atmel device families

Can the selection be automated somehow? Or should I manually compare each finded chip by the conclusions on my board, do they coincide with the functions of the terminals of the AT32UC3L064 chip ?

The cost of UC3L0 256/128 in Russia --- 8$ whitout shiping. And for example ATSAM4S2AB-AN --- 2-5$. I wanted the same low price of the chip and DSP instructions. Since I bought the AT32UC3L064 chip for 1.2-1.5 dollars in 2012 yeare

SAM L11 is approx 2USD to 2.5USD each in quantity 1 though in 32 pins and probably from Thailand.

I can't come close to that in Cypress PSoC 5LP.

That's quite low cost, and it'snot surprising a part moving to maintenance mode, has the increasing price and reduces choices. Their focus is on keeping customers systems working, and they know the re-engineering costs keep some customers captive.. ;)

 

 

Possibly a M4 may do ?

https://direct.nuvoton.com/tr/m451mlc3ae   is 72MHz  72kF 16kR  $1.23/1k

or

https://direct.nuvoton.com/tr/m4521le6ae   72MHz  128kF 32kR  $1.67/1k

 

 

or a bump to the faster family... ?

https://direct.nuvoton.com/tr/m481lidae    192MHz   512kF  160kR  $2.02/1k

These are their problems. They just pour water on the wheel or millstones of their competitors

In general, as I understand it, you will have to manually search and compare the chips. As for pinout and performance ... There is no automated service, as I understand it. So that you can specify the number of conclusions. On which output is the ADC needed, where is the PWM needed and will automatically select different manufacturers and models of the chip. In order not to redo the board.

You could see if their store ships to Russia?

Yup, plus you need to check the peripherals 'map-over' ok and can replace what you already have.

It would be quite rare that no board change was needed, but if the package is the same, maybe some pin-swaps can do it, which is not quite so major.   Same paste mask and same pick and place.

 

It all comes down to how many you make. Small numbers, and the AT32 upgrade is a no-brainer, but large volumes can pay for some engineering time...

I'd expect more time in porting software, than in any PCB Pin-swaps.  I'd start with a M48x which (hopefully) has some speed margin, and then see if a M45x can be made to work..

 

Maybe you could try and order one of

https://direct.nuvoton.com/tr/numaker-m483kg-pre-order

or

https://direct.nuvoton.com/tr/numaker-etm-m487

and see what software porting involves...

I think it would be better to choose the cheapest and most common chip for performance. And order a small board layer between the chip and the main board. To install any chip through the interlayer on finished boards.

Sure, that can work too. It's more work, but can be valid depending on the sign-offs and approvals needed for a full board change & size of things like a retro-fit market.

Sometimes, it is simpler to side-step the red tape... ;)

 

( A 0.5mm interlayer board is going to be tricky to make and mount.. ?)  Send us images when you have this done.

I did not make such interlayer boards. I think a two-layer board needs 0.6-1mm. Soldering it is not a problem, it is simply huge in comparison with the repair of cell phones.

 

For example, it was the case I had in the absence of a flexible wire assy on the Nokia Lumia 920 to restore the electrical contacts of the cable, which is glued to the board. To restore the functionality of the SIM card. )) And I had to dozens of contacts, between the board and a flexible cable, soldered through individual pieces of 0.1mm wire )) Well, to design and solder the adapter board with just 48 contacts is a children's task. )))

 

Many different printed circuit boards are made according to the principle of Miscellaneous interlayer and soldered through Castellated Holes

The simple answer to this is if you contact Atchip-Micromel and tell them you will buy 1million of the part you have now each year for X many years they will keep.producing them. Unless you need a bigger part?

You are joking? If I had large volumes. I would have huge profits. And this problem would not be pressing for me at all ...
