XHSC (Xiaohua Semiconductor) · 小华半导体有限公司
State-Backed Design House
Chinese name: 小华半导体有限公司 (Xiǎohuá Bàndǎotǐ)
The state-aligned ‘MCU + OS’ stack for信创, white goods and automotive body/power domains: scale (300M units/yr), full automotive safety certification chain, and captive specialty-fab backing — plus a February 2025 AUTOSAR pact with CETC’s 普华 OS vendor that pairs domestic silicon with a domestic car OS, deepened in July 2026 when the XC27x series (dual Cortex-M7, ASIL-B, 12×CAN-FD + GbE) completed adaptation to 普华 OrientAIS CP. In early February 2026 XHSC announced its XC38 automotive MCU had taped out on a fully domestic mature process: multi-core ASIL-D lockstep at 400MHz (claims higher DMIPS than comparable Infineon/NXP parts at the same node), targeting e-drive, 800V BMS, ZCU and AEB safety domains, with samples to OEMs/Tier-1s through 2026.
What does this firm design?
General/motor/automotive/ultra-low-power 32-bit MCUs (HC32 lines, plus the XC-series automotive MCUs) and supporting RTOS/AUTOSAR software.
