Historically, electronics manufacturing in our country has been characterized by relatively small production volumes of devices with specific, sometimes unique, characteristics and functional capabilities. This often contradicted the standard approach to Electronic Component Base (ECB) development, which is typically geared toward high-volume and mass production of unified standard parts. However, it turns out that this problem can be solved.

JSC “NIIET” (part of the Element Group, MOEX: ELMT) recently launched serial production of  RISC-V architecture microcontrollers. This line includes the K1921VG3T, a universal energy-efficient 32-bit microcontroller with motor control functions. It features a wide range of built-in interfaces and functional blocks, including:

• Nine dual-channel PWM blocks;
• Six capture and compare modules;
• Two pulse quadrature decoders;
• Three 11-channel 12-bit ADCs and two 12-bit DACs;
• Three analog comparators;

and also, a QSPI port, six UART ports, four LIN, four SPI, USB 2.0 Full Speed, and a 10/100/1000 Ethernet interface.

With a core clock frequency of 120 MHz, 1 MB of program Flash, 32 KB Flash memory, 256 KB of SRAM and EMC (External Memory Controller) supporting SRAM, ROM, NOR Flash and SDRAM, the K1921VG3T is originally produced in a high-pin-count LQFP-208 plastic package.

One of NIIET’s customers tested this microcontroller and found it perfect for their task, except for its physical dimensions. Since the customer’s project did not require all of the available functions, NIIET specialists proposed packaging the existing die in a more compact LQFP-100 package.

By omitting access to the external memory controller, Ethernet, and USB, the team created a new IC — the K1921VG11T. This product required no additional costs from the customer, since key components were already established in production.

Given its versatile feature set, the K1921VG11T will soon be available for the general market, including retail. Technical documentation and developer models will be provided via the NIIET website and repositories.

The institute is already working on a second similar project: the K1921VG10Ya. Based on the dual-core K1921VG1T die, this new component will be manufactured in a compact BGA-225 package to meet client’s specific needs. Through these projects, the Voronezh-based Scientific Research Institute of Electronics confirms its commitment to a flexible, customer-centric approach. By leveraging existing R&D reserves and mass-produced products, NIIET creates efficient solutions for specific requirements.
