Yuntu Semiconductor Closes Hundreds of Millions of RMB in Series B1 Funding | BlueRun Ventures

Recently, Jiangsu YTMicro Semiconductor Co., Ltd. (hereinafter referred to as "YTMicro") completed its Series B1 financing round of several hundred million RMB, with investment from Dioo Microcircuits, Qiandao Fund, and Jingxiang Capital. Since its founding three years ago, YTMicro has adhered to a corporate strategy that emphasizes both innovative R&D and commercialization.

Previously, BlueRun Ventures was an investor in YTMicro's Pre-A and Series A rounds. From product development to business design wins and mass production shipments, YTMicro has attracted industry-wide attention as a "dark horse" for its rapid pace of growth. This latest round of financing — completed swiftly and with continued investor confidence — is a strong validation of its position as a leading domestic automotive-grade chip company.

At the National Strategy Level

At the national strategy level, building an independent and controllable semiconductor supply chain and breaking through core chip technology barriers has become a shared priority across both the semiconductor and automotive industries. As vehicles become increasingly intelligent, connected, and electrified, 32-bit automotive-grade general-purpose MCUs have become critical core chips across the vehicle's five major domains — both in terms of volume and performance requirements. Over three years, YTMicro has gradually earned market recognition through safe, reliable, and stable product quality.

To date, YTMicro has established deep partnerships with dozens of OEMs and well-known domestic automotive component manufacturers, securing 300+ design wins and shipping millions of units. The next three to five years will mark YTMicro's entry into a phase of high-speed growth. Building on its 17 already-mass-produced chips, YTMicro will fully deploy across the automotive market, deepen product application development, and commit to becoming a leading domestic automotive chip enterprise.

In August this year, YTMicro released the YTM32BIHA series of high-performance multi-core processor chips. Within just three months of launch, it has reached design win cooperation intentions with multiple customers and entered the application development and design phase. The YTM32BIHA is a high-performance automotive-grade MCU with multiple Cortex-M7 cores, supporting high-bandwidth, high-reliability on-chip embedded flash memory. It supports ASIL-D functional safety certification and meets AEC-Q100 Auto-Grade 1 standards, with applications in automotive powertrain, chassis, functional safety controllers, domain controllers, and other areas.

Currently in a phase of rapid growth, YTMicro will continue to increase R&D and mass production investment in high-performance automotive processor chips, expand industrial ecosystem partnerships, and deepen strategic business collaboration with OEMs and Tier 1 suppliers — jointly shaping a new paradigm for domestic intelligent automotive chip development.
