[CNX-Software] - Milandr MDR32F02FI is a RISC-V microcontroller for (Russian) electricity meters

Last year, we wrote about the Made-in-Russia Mikron MIK32 RISC-V microcontroller with features similar to STM32L0 Arm Cortex-M0+, and I was recently told that the first fully packed samples are expected for the end of autumn. But it turns out there’s another Russian company that makes RISC-V microcontrollers, and for instance, the Milandr MDR32F02FI features the open-source BM-310 RISC-V MCU core and is specially designed for electricity meters. It is the second generation of the microcontroller with the first being based on Arm Cortex-M0 core and produced for over 5 years. Milandr MDR32F02FI specifications: CPU – CloudBEAR BМ-310S 32-bit RISC-V core @ 60 MHz Memory – 112KB Storage – 256+8 KB flash, 16KB OTP Electricity meter function 7-channel 24-bit sigma-delta ADC Hardware unit for calculating power consumption Other Peripherals 5x UART, 3x SPI, 1x I2C Up to 55x GPIOs Instrumental ADC – 10-bit with temperature sensor 4x 32-bit timer blocks [...]
