Is there a KiCad symbol and footprint for the M253LE3AE?
Yes. The symbol is Celestial_MCU_NUVOTON:NUVOTON M253LE3AE and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the M253LE3AE?
LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.
Where can I order the M253LE3AE?
JLCPCB lists it as part C5371135, with 0 in stock; the sellers' links on this page open their listings.
What can replace the M253LE3AE?
Parts like it in the library: the STM32F103C8T6 by STMicroelectronics, the STM32F030C8T6 by STMicroelectronics, the STM32G070CBT6 by STMicroelectronics and the STM32G030C8T6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
