Mikron MIK32 – Made in Russia 32-bit RISC-V MCU offers features similar to STM32L0 MCU

The Mikron MIK32 is a 32-bit RISC-V microcontroller made in Russia with features similar to an STMicro STM32L0 Cortex-M0+ MCU that shows how RISC-V open-source architecture can help lower the barrier to entry, and let more companies design their own chips.

The MIK32 microcontroller features CPU IP from Syntacore based in Saint Petersburg following the RV32IMC profile. Clocked at 32 MHz, the MCU comes with I2C, UART, SPI, ADC, DAC interfaces, as well as various timers, an interrupt controller, and more.

Mikron MIK32 development board
Mikron also designed a development board with a MIK32 module, multiple relays, buttons, DIP configuration switches, RS232/RS485, and supports for four expansion boards adding Bluetooth, WiFi, GSM, NB-IoT, Zigbee, RFID, and/or Ethernet to the board.

Mikron MIK32 is said to be suitable for gas/water meters and industrial sensors, healthcare and fitness equipment, remote control and user interfaces, as well as PC peripherals, gaming, and GPS equipment.

The MIK32 RISC-V MCU is sold for 450 roubles or about $6, but I’m not sure if it is unit price or in quantities. The company asks interested parties to contact them to purchase the microcontroller or development board. More information can be found on the company’s website. Everything is in Russian, except for a product sheet in English with basic specifications.
