The KSZ8862M is 2-port switch with fiber support, available in 8-/16-bit and 32-bit bus designs.
The KSZ8862M is an industry first, fully managed, 2-port switch. It is based on a proven, 4th generation, integrated Layer-2 switch, compliant with IEEE 802.3u standards.For industrial applications, the KSZ8862M can run in half-duplex mode regardless of the application. In fiber mode, port 1 can be configurable to either 100BASE-FX or 100BASE-SX/10BASE-FL. The LED driver and post amplifier are also included for 10Base-FL and 100Base-SX applications.In copper mode, port 2 supports 10/100BASE-T/TX with HP Auto MDI/MDI-X for reliable detection of and correction for straight-through and crossover cables.
Microchip's proprietary LinkMD® Time Domain Reflectometry (TDR) based function is also available for determining the cable length, as well as cable diagnostics for identifying faulty cabling.The KSZ8862M offers an extensive feature set that includes tag/port-based VLAN, quality of service (QoS) priority management, management information base (MIB) counters, and CPU control/data interfaces to effectively address Fast Ethernet applications.
The KSZ8862M contains:
- Two 10/100 transceivers with patented, mixed-signal, low-power technology
- Two media access control (MAC) units
- Direct memory access (DMA) channel
- High-speed, non-blocking, switch fabric
- Dedicated 1K entry forwarding table
- On-chip frame buffer memory
When using the provided KSZ8462 software driver, please exclude the 1588 PTP code at compile time.

iPhone 15最大的改变之一是全系列都升级为Type-C接口,终于放弃了使用了十多年的Lightning接口。
在嵌入式领域,TFT-LCD屏是最常用的显示解决方案之一,因为它们提供了丰富的颜色和高分辨率的图像显示能力。STM32H5作为ST的高性能微控制器系列,具备了强大的处理能力和多种通信接口,非常适合于驱动TFT-LCD显示屏,该液晶屏st7796或者ILI9488驱动芯片,这两个屏幕都是兼容的。
嵌入式微处理器的架构可以分为以下几类模块: 中央处理单元(CPU):嵌入式微处理器的核心部分,负责执行指令、进行数据运算和控制任务。它包括控制单元(CU)和算术逻辑单元(ALU)。 存储器模块:用于存储程序指令和数据。通常包括内部存储器(如RAM和ROM)和外部扩展存储器(如闪存、SD卡等)。 总线系统:连接处理器和其他外部设备的通信通道。它可以分为数据总线、地址总线和控制总线,用于传送数据、地址和控制信号。 定时器模块:用

单个医用吊塔的功率约为1.5kVA,项目中选择使用8VA容量的隔离变压器同时为5台医用吊塔供电。因为隔离变压器在启动时会产生较大的冲击电流,可能会造成隔离变压器一次侧断路器断开或闭合困难,所以本项目在选择隔离变压器进出线的断路器时,按照国标选择了只有短路保护功能没有过负荷保护功能的断路器,断路器脱扣曲线应为D型。
嵌入式微处理器是一种专门设计用于嵌入式系统应用的微处理器,通常集成了计算、控制和通信等功能。目前市场上存在两种主要的嵌入式微处理器架构,分别是CISC(复杂指令集计算机)和RISC(精简指令集计算机)。 CISC架构是指具有复杂指令集的处理器架构。其特点是指令集较为庞大和复杂,每条指令可以完成较为复杂的操作,并且指令中包含了多个机器周期的操作。CISC架构的处理器具有较大的指令集,能够在一条指令内完成多个操作,并且对于复
电子发烧友网报道(文/李弯弯)12月24日晚间,小米在社交平台发布《关于针对我司投资业务相关谣言的声明》称:“近日,有大量关于某芯片公司与小米相关的谣言和不实报道在网上流传。对于这些不负责任、完全失实的信息,我们已经完成取证并上报有关部门。” 事情源于上周四上海市公安局经济犯罪侦查总队官方微信公众号发布的一篇文章《上海警方侦破侵犯芯片技术商业秘密案》,该文显示,近期在公安部的指挥部署下,在江苏警方的大力配
