Description: 概述
● 全速设备接口，兼容 USB V2.0，外围元器件只需要晶体和电容。
● 可选：通过外部的低成本串行EEPROM 定义厂商 ID、产品 ID、序列号等。
● 支持5V电源电压和3.3V电源电压。
● 低成本，直接转换原串口外围设备、原并口打印机、原并口外围设备。
● 采用SOP-28封装，串口应用还提供小型的 SSOP-20 封装。
● 由于是通过USB转换的接口，所以只能做到应用层兼容，而无法绝对相同。 -Say all
● The full speed equipments connects, and permit the USB V2.0, a machine of outer circle piece needs the crystal and electric capacities only.
● Eligibility:The low cost string that passes the exterior goes the EEPROM to define factory ID, product ID, etc. sequence.
● Support the 5 V power supply electric voltage and 3.3 V power supply electric voltages.
● Low cost, direct conversion original a peripherals, original combine a printer, original combine a peripherals.
● Adopt the SOP-28s pack, an application still provides small scaled SSOP-20s to pack.
● In view of the fact convert through an USB of connect, so can make to apply the layer and permit only, but can t absolute homology. Platform: |
