The EZ-USB chip packs the intelligence required by a USB peripheral interface into a compact integrated circuit. A Serial Interface Engine (SIE) decodes and encodes the serial data and performs error correction, bit stuffing, and other signaling-level details required by USB, and ultimately transfers data bytes to and from the USB interface.
EZ-USB 芯片将 USB 外设接口所需的指令装入一个小型集成电路中。串行接口引擎 (SIE) 可对串行数据进行解码和编码,并执行 USB 所需的纠错、位填充及其他收发信号的具体操作,还可将数据字节转入/转出 USB 接口。
The CY7C647XX (EZ-USB FX1TM) is a family of full-speed highly integrated, USB Microcontrollers. the FX1 family integrates the USB transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip. The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8- or 16-bit data bus) provides an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors.
The EZ-USB chip packs the intelligence required by a USB peripheral interface into a compact integrated circuit. A Serial Interface Engine (SIE) decodes and encodes the serial data and performs error correction, bit stuffing, and other signaling-level details required by USB, and ultimately transfers data bytes to and from the USB interface. The internal microprocessor is enhanced 8051 with fast execution time and added uses internal RAM for program and data storage, making the EZ-USB family a soft solution. The USB host downloads 8051 program code and device personality into RAM over the USB bus, and then the EZ-USB chip reconnects as the custom device as defined by the loaded code. The EZ-USB family uses an enhanced SIE/USB interface (called the "USB Core") which has the intelligence to function as a full USB device even before the 8051. The enhanced core simplifies 8051 code by implementing much of the USB protocol itself. EZ-USB chips simplifies the design of bus-powered USB devices, since the 5V power available in the USB connector (which the USB specification allows to be as low as 4.4V) can drive a 3.3V regulator to deliver clean isolated power to the EZ-USB chip.
EZ-USB 芯片将 USB 外设接口所需的指令装入一个小型集成电路中。串行接口引擎 (SIE) 可对串行数据进行解码和编码,并执行 USB 所需的纠错、位填充及其他收发信号的具体操作,还可将数据字节转入/转出 USB 接口。内部微处理器是增强型 8051,具有快速执行时间和附加功能。它使用内部 RAM 存储程序和数据,使 EZ-USB 系列成为一种软件解决方案。USB 主机通过 USB 总线将 8051 程序代码和设备自定义设置下载到 RAM 中,然后按照载入的代码定义将 EZ-USB 与用户设备重新连接。EZ-USB 系列使用增强型 SIE/USB 接口(称为 "USB 核心"),甚至在 8051 之前,它具有可作为完整 USB 设备使用的指令。增强型核心自身可执行大部分 USB 的协议以简化 8051 代码。EZ-USB 芯片工作电压为 3.3V。这简化了由总线供电的 USB 设备的设计,因为 USB 连接器中可用的 5V 电源(USB 技术规范允许降到 4.4V)可以驱动 3.3V 稳压器以便为 EZ-USB 芯片提供完全隔离的电源。
The CY7C68013-56PVC (EZ-USB FX2) is a single-chip integrated USB 2.0 Transceiver, Serial Interface Engine (SIE), and Enhanced 8051 Microprocessor, High Speed 480Mbits/sec. Enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip. Integrated I2C-compatible controller, runs at 100 or 400 kHz, 48-MHz, 24 MHz, or 12 MHz 8051 integrated FIFOs, brings glue and FIFO inside for lower system cost. Automatic conversion to and from 16-bit buses, master or slave operation. FIFOs can use externally supplied clock or asynchronous strobes. Easy interface to ASIC and DSP ICs, up to 40 general purpose I/Os.
The reader can also be triggered remotely through software commands or via hardware input from programmable logic controller (PLC) or sensor.The GFE4400 2D OEM engine supports an RS-232 serial interface, a USB HID Keyboard and a USB COM interface.
The M5475EVB development system provides everything required to quickly develop an embedded design with the MCF547x processor family. The kit contains a system-on-module, called a Fire Engine, containing 64 MBytes of DDR-SDRAM, 16 MB of Flash, a graphics contoller, and a 4-port USB host. The Fire Engine module, along with the included ethernet ports, PCI slots, serial interfaces, and the best-in-class ColdFire debug module generates a complete package to enable quick design support for the MCF5475, MCF5474, MCF5473, MCF5472, MCF5471, or MCF5470 processors.
