Questions

Is there a KiCad symbol and footprint for the CM2249-QFPTR?

Yes. The symbol is EasyEDA_Cloud:CM2249-QFPTR and the footprint Package_QFP:LQFP-80_14x14mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CM2249-QFPTR?

LQFP-80(14x14), with 80 pins. Its footprint is drawn on this page.

Where is the CM2249-QFPTR datasheet?

CIMO publishes it: the Datasheet link on this page opens it.

Where can I order the CM2249-QFPTR?

JLCPCB lists it as part C20606819, with 393 in stock; the sellers' links on this page open their listings.

What can replace the CM2249-QFPTR?

Parts like it in the library: the ADS8686SIPZAR by Texas Instruments, the AD7616BSTZ by Analog Devices, the AD7616BSTZ-RL by Analog Devices and the AD7616-PBSTZ-RL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
