MKL27Z64VLH4 replacement

dusek_martin — Mon, 07 Jun 2021 19:46:25 GMT

Hi,

is there a replacement for MKL27Z64VLH4, which is not in stock?

I need LQFP64, crystalless USB operation (48 MHz internal clock), min 64 kB flash, pin compatibility for power, USB, SWD and analog power/reference. On our board, all MKL27 pins are used, however, no specific function on pins is needed (just GPIO).

Thanks, Martin

Some K32L's will cross to the 27 at the pin level.
Software is not drop in compatible.

Like most everything from most everyone those are not available either.

Can you please give me exact part number? I listed all K32L's with LQFP64 package but unfortunately all 5 parts I got have VOUT33 and VREGIN pins (K27 has USB_VDD pin). This is not compatible with our board.

As I said some of the K32Ls cross, you may have one that doesn't..
