Overview

The CH554G is a microcontroller made by WCH (Nanjing Qinheng Microelectronics) in a SOP-16 package with 16 pins. 16KB 24MHz 3.3V~5V 51 Family 8bit FLASH SOP-16 Microcontrollers (MCU/MPU/SOC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CH554G, from EasyEDA) and its footprint (Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 978 are in stock at JLCPCB (part C114295).

Questions

Is there a KiCad symbol and footprint for the CH554G?

Yes. The symbol is EasyEDA_Cloud:CH554G and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH554G?

SOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the CH554G datasheet?

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

Where can I order the CH554G?

JLCPCB lists it as part C114295, with 978 in stock; the sellers' links on this page open their listings.

What can replace the CH554G?

Parts like it in the library: the STC15W408AS-35I-SOP16 by STC, the CH552G by WCH (Nanjing Qinheng Microelectronics), the STC8G1K08-38I-SOP16 by STC Micro and the PY32F002AW15S6TU by PUYA. Check their datasheets: a part that fits the footprint may still differ in its ratings.
