SF21H8898是芯来科技研发的一款高性能工业级SOC网关芯片。它采用先进的台积电12nm FFC工艺,集成四核64位RISC-V处理器和专用网络处理加速器(NPU)(支持L2/L3硬件处理,IPv4/IPv6双栈,20Gbps交换容量,全字节线速转发),网络侧支持QSGMII、SGMII/HSGMII和RGMII接口。支持IEEE 1588 PTP功能实现时间同步。支持外接DDR3/DDR3L/DDR4 SDRAM和NAND/NOR SPI Flash。高速接口包括USB2.0、PCIE2.0,低速接口包括SPI、UART、I2C、PWM等。可应用于企业网关和工业控制网关。芯来SF21H8898芯片图 芯来SF21H8898芯片典型应用场景

新款香蕉派 BPI-RV2 RISC-V 网关板发布后,在 Hacker News 社区引起了关注。用户 sylware 对新的 RISC-V 硬件表示兴奋,但同时也希望未来能有高性能的 64 位实现。他还询问该板上的 USB 控制器是否支持设备模式。原作者 ofrzeta 回复引用了数据手册,指出该芯片支持 USB OTG,因此既可以作为主机,也可以作为外设工作。另一位用户 colechristensen 理解为该设备可以作为外设工作。

SF21H8898 is a high performance industrial-grade SOC gateway chip developed by Siflower Communications. It adopts advanced TSMC 12nm FFC process and integrates four cores inside 64-bit RSIC-V processor and dedicated network processing accelerator (NPU) (supports L2/L3 hardware processing, IPv4/IPv6 dual stack, 20Gbps switching capacity, full byte wire-speed forwarding), network-side support for QSGMII, SGMII/HSGMII and RGMII interfaces. IEEE 1588 PTP functionality is supported for time synchronization. It supports external DDR3/DDR3L/DDR4 SDRAM and NAND/NOR SPI Flash. The high-speed interface is USB2.0, PCIE2.0, and the low-speed interface is SPI, UART, I2C, PWM, etc. It can be used as enterprise gateway and industrial control gateway.
