WCH Adds Upcoming RISC-V Bluetooth LE Microcontroller To CH57x Family

By February 20, 2019May 12th, 2021No Comments

Embedded news site CNXSoft has highlighted an upcoming part from Jiangsu Qinheng Co., Ltd, also known as WinChipHead (WCH), which combines a RISC-V core running at 60MHz with Bluetooth Low Energy (BLE) connectivity.
Recently added to WCH’s parts list, the 32-bit microcontroller has been dubbed the CH572 – putting it into the same CH57x family as the company’s Arm Cortex-M0 microcontroller offerings – and is claimed to run at 60MHz. Full details haven’t yet been supplied by the company, but CNXSoft’s analysis of the available information found a part with 10KB of SRAM, 96KB of one-time programmable (OTP) flash memory, Bluetooth Low Energy (BLE) connectivity, USB Host and USB Device support, an 11-channel 12-bit analogue to digital converter (ADC), three 26-bit timers, 11 pulse-width modulated (PWM) pins, two UARTs, one SPI, 23 GPIOs, real-time clock, and watchdog support, all running on a supply voltage of 3.3V or 2.5V and in a QFN28 package.
