As a key player in digital-analog hybrid SoCs, iSmartWare has hit a major milestone in fast-charging standardization. Its latest chip, the SW6328, has officially secured UFCS certification (Cert: 0302647160690R0M-UFCS00273). Jointly launched by industry heavyweights including CAICT, Huawei, OPPO, vivo, and HONOR, the UFCS standard eliminates protocol fragmentation across the power bank sector. iSmartWare’s achievement marks a major leap forward in protocol universality and domestic autonomy, empowering manufacturers to efficiently roll out compliant, high-power energy storage solutions.
Tailored for new national standards and outdoor power stations, the SW6328 is an A+C+C three-port multi-protocol buck-boost SoC. It packs a high-performance MCU, bidirectional buck-boost controller, and fast-charging PHYs directly onto the silicon. Supporting 2 to 6 series cells of ternary lithium, LiFePO4, or sodium-ion batteries, it handles up to 100W of charge/discharge power. On the protocol front, it natively integrates dual independent DPDM and PD PHYs with hardware-level UFCS and PD3.2 support. UFCS output hits up to 100W—scalable to 140W—with direct drive capabilities for vibrant TFT color displays. Additionally, a built-in hardware coulomb counter supports self-learning battery capacity alongside multi-channel high-precision ADC temperature sensing, effortlessly meeting safety and thermal rules like IEC62368. With comprehensive hardware protections including a >30V VBUS tolerance, the SW6328 slashes external discrete component counts, lowering BOM expenses and speeding up time-to-market.
Securing UFCS certification establishes the SW6328 as a secure, homegrown technological backbone for the fast-charging supply chain. Moving forward, as domestic semiconductor firms like iSmartWare continue to champion the unified ecosystem, the UFCS alliance will expand even further. Driven by these highly integrated SoCs, homegrown power chips are dismantling protocol silos and driving green, low-carbon, premium upgrades across the consumer and industrial power sectors.
