USB 공부를 위한.. 첫번째걸음

Cypress CY7C68013 칩 안내.
datasheet를 확인할 수 있다!

이건. CY7C68013A
EZ-USB FX2LP(TM) USB Microcontroller

Features

  • USB 2.0-USB-IF high speed certified (TID # 40440111)
  • Single-chip integrated USB 2.0 transceiver, smart SIE, and enhanced 8051 microprocessor
  • Fit, form and function compatible with the FX2
    • Pin-compatible
    • Object-code-compatible
    • Functionally-compatible (FX2LP is a superset)
  • Ultra Low power: ICC no more than 85 mA in any mode
    • Ideal for bus and battery powered applications
  • Software: 8051 code runs from:
    • Internal RAM, which is downloaded via USB
    • Internal RAM, which is loaded from EEPROM
    • External memory device (128 pin package)
  • 16 KBytes of on-chip Code/Data RAM
  • Four programmable
  • BULK/INTERRUPT/ISOCHRONOUS endpoints
    • Buffering options: double, triple, and quad
  • Additional programmable (BULK/INTERRUPT) 64-byte endpoint
  • 8- or 16-bit external data interface
  • Smart Media Standard ECC generation
  • GPIF (General Programmable Interface)
    • Allows direct connection to most parallel interface
    • Programmable waveform descriptors and configuration registers to define waveforms
    • Supports multiple Ready (RDY) inputs and Control (CTL) outputs
  • Integrated, industry-standard enhanced 8051
    • 48-MHz, 24-MHz, or 12-MHz CPU operation
    • Four clocks per instruction cycle
    • Two USARTS
    • Three counter/timers
    • Expanded interrupt system
    • Two data pointers
  • 3.3V operation with 5V tolerant inputs
  • Vectored USB interrupts and GPIF/FIFO interrupts
  • Separate data buffers for the Set-up and Data portions of a CONTROL transfer
  • Integrated I2C controller, runs at 100 or 400 kHz
  • Four integrated FIFOs
    • Integrated glue logic and FIFOs lower system cost
    • Automatic conversion to and from 16-bit buses
    • Master or slave operation
    • Uses external clock or asynchronous strobes
    • Easy interface to ASIC and DSP ICs
  • Available in Commercial and Industrial temperature grade (all packages except VFBGA)

File Checksum Integrity Verifier utitilty.

MS 에서 제공하는 파일 무결성검증도구.

SHA-1 , MD5 해시값을 추출해줍니다.

MS에서 다운로드 받은파일을 검증하는데에도 사용되죠.

기본사용법은

Fciv -{sha1 | md5} filename

하시면됩니다.

system32 나 Windows 폴더에 넣어두면 편하게 쓰일 수 있을것 같군요.
