Overview

The M031LE3AE is a microcontroller made by Nuvoton Tech in a LQFP-48(7x7) package with 48 pins. -40℃~+105℃ 1.8V~3.6V 128KB 12bit 16KB 32 Bit 42 48MHz ARM Cortex-M0 Built-in FLASH LQFP-48(7x7) Microcontrollers (MCU/MPU/SOC) ROHS.

PCBKit's library has its KiCad symbol (Celestial_MCU_NUVOTON:NUVOTON M031LE3AE, from Altium's library) and its footprint (Package_QFP:LQFP-48_7x7mm_P0.5mm, from KiCad's library), ready for a KiCad board. 2,131 are in stock at JLCPCB (part C2917264).

Questions

Is there a KiCad symbol and footprint for the M031LE3AE?

Yes. The symbol is Celestial_MCU_NUVOTON:NUVOTON M031LE3AE 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 M031LE3AE?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the M031LE3AE datasheet?

Nuvoton Tech publishes it: the Datasheet link on this page opens it.

Where can I order the M031LE3AE?

JLCPCB lists it as part C2917264, with 2,131 in stock; the sellers' links on this page open their listings.

What can replace the M031LE3AE?

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.
