MERI developed 64-bit and 32-bit serial communication microcontrollers

MERI engineers developed a 64-bit microcontroller based on the 64-bit core NE64RV and created a prototype of a universal 32-bit microcontroller with a RISC-V core. Both products were developed as a part of the import substitution program.

The 5549TKO microcontroller has accelerated performance due to 64-bit architecture while maintaining small size of the chip on the wafer. It contains a 64-bit RISC-V core, an accessing SPI-flash memory controller, antifuse-based OTP memory, standard microcontroller interfaces (UART, GPIO), JTAG-interface for downloading and debugging the software, general purpose timers, etc.

The microcontroller can be used for IoT, telecommunications, household appliances, smart home devices.

The prototype of the universal 32-bit microcontroller is based on PLD (Programmable Logic Device). The 32-bit RISC-V core that is used in the prototype has better performance than ultra-compact ARM Cortex-M0 core with almost the same number of equivalent gates. In fact, the prototype reminds an assembly kit with different IP-blocks, coprocessors, encryption modules and interfaces. It allows to configure a product according to customer’s requirements much faster. The product includes all the necessary software development tools and technical documentation.

On customer request MERI engineers will configure and modify a product with an expanded set of interfaces and a hardware random number generator (HRNG). Optionally, all the hardware and software security instruments could be applied to certify the final product for its usage in bank cards or cryptographic security tools. Therefore, this prototype microcontroller can become a basis for special chips, that are applied in electronic IDs, credit cards, SIM-cards, IoT and other high security elements.

As MERI Chief designer, Alexander Kravtsov noted, “Today IoT is one of the main drivers of the world high-tech market. At the same time to ensure the technological independence and data security of national projects it is necessary to create our own hardware components and also to provide the IoT-devices manufacturers with these certain components. Our new microcontrollers can replace imported ICs in wide range of devices and allow Russian design centers to use trusted national product.”

Today more than 600 highly qualified specialist work for MERI JSC, including 3 RAS academicians, 2 RAS corresponding members, more than 70 PhDs and ScDs. The institute cooperates with more than 60 Russian and foreign scientific and design centers, universities and fabs.
