What Zhenghe Microchip does
Zhenghe Microchip (珠海正和微芯科技有限公司), doing business as Possumic / 正和微芯, is a fabless semiconductor company founded in 2020 and headquartered in Zhuhai, China, that designs millimeter wave radar SoC chips and modules for industrial electronics and vehicle electronics applications. The company's product portfolio spans three frequency bands — 24GHz (RS2111 chip and MRS251/MRS261L/MRS262 AoB modules), 60GHz (RS6130, RS6240, RS6241 chips), and 77GHz (RS7241 automotive chip) — integrating radar RF front-end, baseband signal processing, application processors, and on selected parts multi-protocol 2.4GHz wireless connectivity (BLE 5.3, IEEE 802.15.4, Thread 1.3, Matter 1.1) into single-chip AiP (Antenna in Package) form factors. Core proprietary technologies include the EFSENS ultra-low-power human presence detection architecture (4μA on 24GHz matching PIR consumption; 10μA-grade on 60GHz), AiP antenna designs with industry-leading bandwidth and gain, and patented FMCW phase-tracking and anti-interference algorithms. Differentiation rests on three axes: power consumption parity with legacy PIR sensors enabling battery-powered deployment, single-die integration of sensing plus multi-protocol wireless reducing BOM and PCB complexity, and ultra-compact packaging down to a 2.5×2.5mm QFN.
The company sells its silicon primarily through direct business contact ([email protected]) to enterprise customers for bulk and customized orders, complemented by an authorized Taobao storefront and WeChat mini-store for samples and development kits, with a distributor/agent network under development. Pricing is not publicly disclosed and requires sales engagement. The supported development ecosystem includes three development kits (MRS2-DEV-BOX, RS6130-AIP-DEV-BOX, RS6240-AIP-DEV-BOX), embedded SDKs (RS6x_7x_mmWave_sdk, MRS2xx_Motion SDK), a CDK IDE, PC-side demo and analysis tools, and a developer community on CSDN, GitHub, and Bilibili — positioning the firm as a product-led, developer-friendly chip vendor. Target verticals are smart home (lighting, presence sensors, smart switches, appliances), smart security (door locks, doorbells, battery IPC cameras), smart automotive (BSD, in-cabin detection, automatic doors, two-wheeler helmets, AVP), and smart industrial (logistics robotics, parking gates, drones). Revenue is not publicly disclosed; the company raised tens of millions of RMB in a 2022 angel round from Datai Capital, Hengqin Golden Investment (Gree Group), and High-Tech Golden Investment, followed by approximately 100 million RMB in a December 2024 Series A led by Deep Cooperation Production Investment and Junshi Venture Capital, with explicit use of proceeds to accelerate mass production and market expansion. The company is recognized as a National High-Tech Enterprise (2023), a Specialized & Novel SME, Seed Unicorn, and Gazelle Cultivation Enterprise, and holds ISO 9001:2015 and IP Management System certifications.
