Overview

The CH547L is a microcontroller made by WCH (Nanjing Qinheng Microelectronics) in a LQFP-48(7x7) package with 48 pins. LQFP-48(7x7) Microcontrollers (MCU/MPU/SOC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CH547L, from EasyEDA) and its footprint (Package_QFP:LQFP-48_7x7mm_P0.5mm, from KiCad's library), ready for a KiCad board. 2 are in stock at JLCPCB (part C2932457).

Questions

Is there a KiCad symbol and footprint for the CH547L?

Yes. The symbol is EasyEDA_Cloud:CH547L 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 CH547L?

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

Where is the CH547L datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH547L?

JLCPCB lists it as part C2932457, with 2 in stock; the sellers' links on this page open their listings.

What can replace the CH547L?

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.
