Oct 15, 2022
WCH Nanjing Qinheng Microelectronics Co Ltd. founded in 2004,
is an IC communication interface and full-stack MCU design company. The company Bluetooth IC CH573 enables the Gamepad controller Bluetooth connectivity. This gamepad can be used with smart TV, PC, mobile and so on.
CH573 Features
CH573 has a 32-bit RISC-V core running at 20 MHz. The device on-chip Flas to SRAM ratio is ~28 which I found to be quite interesting. The IC also has a touch key detection unit. The company is mainly targeting the local Chinese customers and publishes its datasheet in Chinese.
