Overview

The CH573F is a microcontroller made by WCH (Nanjing Qinheng Microelectronics) in a QFN-28-EP(4x4) package with 29 pins. -40℃~+85℃ 12bit 18KB 2.3V~3.6V 20MHz 32 Bit 448KB Built-in+External FLASH RISC-V QFN-28-EP(4x4) Microcontrollers (MCU/MPU/SOC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CH573F, from EasyEDA) and its footprint (EasyEDA_Cloud:QFN-28_L4.0-W4.0-P0.40-BL-EP, from EasyEDA), ready for a KiCad board. 122 are in stock at JLCPCB (part C2830434).

Questions

Is there a KiCad symbol and footprint for the CH573F?

Yes. The symbol is EasyEDA_Cloud:CH573F and the footprint EasyEDA_Cloud:QFN-28_L4.0-W4.0-P0.40-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH573F?

QFN-28-EP(4x4), with 29 pins. Its footprint is drawn on this page.

Where is the CH573F datasheet?

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

Where can I order the CH573F?

JLCPCB lists it as part C2830434, with 122 in stock; the sellers' links on this page open their listings.

What can replace the CH573F?

Parts like it in the library: the GD32F350G8U6TR by GigaDevice Semicon Beijing, the GD32F130G8U6TR by GigaDevice, the GD32F130G6U6TR by GigaDevice Semicon Beijing and the HK32F403GBU7 by HK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
