New WCH microcontrollers: CH32X305, CH32X315, and CH32V205
In addition to the notable CH32V407 and CH32V467 recently announced in this sub, WCH offers 3 other highly capable microcontrollers.
CH32X305 / CH32X315
The CH32X315 is a multi-channel ADC microcontroller based on the Qingke V3F RISC-V core, supporting 417MHz zero-wait operation. It integrates 4 high-speed 12-bit ADC, providing 48 direct input channels, supporting scan mode, and can be expanded to 8 times the number of channels with automatic switching when paired with analogue switching chips. It also includes a built-in USB 3.0 high-speed controller and PHY, a USB 2.0 high-speed controller and PHY, and a Type-C/PD controller and PHY, supporting USB 3.2 Gen1, USBSS Device functionality, USBHS Host and USBHS Device functionality, and Type-C and PDUSB fast charging. It provides a rich set of peripherals, including a DMA controller, ARGB single-wire RGB driver, multiple timers, 4 USART, 2 I2C ports, and 3 SPI ports.
The CH32X305 is based on the CH32X315 but without the USB 3.0 module.
CH32V205
The CH32V205 is an industrial-grade general-purpose microcontroller based on the Qingke V3B RISC-V core. It integrates a USB 2.0 high-speed PHY transceiver (480Mbps) and a PD PHY, supporting PDUSB, including USB Host and USB Device functions, USB PD and Type-C fast charging capabilities. It provides a rich array of peripherals, including a programmable protocol I/O controller (PIOC), a static memory controller (FSMC), a QSPI interface, a CAN interface, 8 USART, 2 I2C ports, 2 SPI ports, multiple timers, 2 operational amplifiers, 2 voltage comparators, a 4Msps high-speed 12-bit ADC, and 16 Touchkey channels.
