ISD通用开发板HY—3340A是专为ISD33000/4003/4004系列器件而设计的。电路板结构小巧精致,接口方便灵活,既可用于开发、测试,又可用于批量生产。HY—3340A现已开发两种通用程序:HY—3340A1和HY—3340A2。 HY-3340A1:8X2按键接口,两位VL指示录放音状态,两位数码显示段号,加、减、选段,1～8段可由按键1～8直接触发。段内可快进、快退、暂停。 HY—3340A2:8位独立按键直接触发1～8段录放音,按键7～1按二进制组合可分127段。SN单键操作可顺序触发1～127段的录放音。 1.性能特点 (1)支持ISD所有3V器件:ISD33000/4003/4004系列。
The ISD Universal Development Board HY-3340A is designed for the ISD33000 / 4003/4004 family of devices. Compact circuit board structure, the interface is convenient and flexible, both for development, testing, but also for mass production. HY-3340A has developed two general procedures: HY-3340A1 and HY-3340A2. HY-3340A1: 8X2 button interface, two VL indicates recording playback state, two digit display section number, plus, minus, electoral paragraph, 1 ~ 8 segments can be directly triggered by the button 1 ~ 8. Section can fast forward, rewind, pause. HY-3340A2: 8-bit independent buttons directly trigger 1 ~ 8 recording and playback, press 7 ~ 1 can be divided into 127 segments by binary combination. SN One-button operation can be triggered sequentially 1 ~ 127 recording and playback. 1. Performance Features (1) Supports all ISV 3V devices: ISD33000 / 4003/4004 series.
