(12). 特殊功能选项 短触发循环播放 (Edge-Loop):当TG按键一被触发,TG的闪灯组会一直循环播放.如果结 合Loop On/Off 功能,再触发该按键,闪灯会停止,再次触发则循环播放TG的闪灯组. 注意: Loop On/Off 与Toggle On/Off ?能同时存在. (13). 特殊功能选项 杂讯触发 (Noise-Trigger): 当选择此功能时,TG被设定为 Edge/Unhold 功能,应用时需 将TG输入在PCB的Layout做成较长的输入线,当外部有较大的杂讯产生时,?用天线效应的原??产生输 入讯号,TG外部悬空?需?接到VDD或GND脚.(此功能常?於电子打火机和手机天线的应用) (14). 低压?位(LVR) 选项,当电压瞬间低於1.5V时,IC 会自动?位.(光罩选择) (要进一步?解上述功能,请?考Q-Light的使用手册,或?系九齐科技或九齐代?商.)

5 1. GENERAL DESCRIPTION The NY1A series are single-chip LED Control and Drive synthesizing CMOS IC. There are

2 bodies: NY1A003A and NY1A103A. Through the accurate internal oscillation of built-in Rosc, an external Rosc is not required. Each output can provide different kinds of current output cooperating with software current control to drive different brightness LED, and optional constant current is also provided to protect LED, thus it'

s not necessary to add the external current-limit resistor. The LED pattern consists of programmable square waveform, oblique and curve, user can compose varied pattern and then the customized LED data can be programmed into ROM by changing one code mask during fabrication. Besides, the interactive software developing tool of Q-Light is user-friendly and quick for programming. 2. FEATURES (1). Wide operating voltage: 1.6V ~ 6.4V. (2). There are

2 bodies. The I/O counts and maximum ROM size are as following. P/N NY1A003A NY1A103A I/O 1*I/O, 2*O 1*I/O, 2*O ROM DC0H 1B80H (3). NY1Ax03A has

3 I/O pins: TG can be either input or output pin. The O1 and O2 can only be output pin. (Mask option) (4). The total LED pattern can be partitioned up to maximum

8 LED Sections. Each LED Section length is flexible. The LED Section data length must be the multiple of 40H (Hex). The time unit of each LED sample can be 1/128 sec or 1/16 sec. Cooperating with time extension option of x1, x2, x4 and x8, there are total

7 options selectable. (1/128, 1/64, 1/32, 1/16, 1/8, 1/4, 1/2 sec) (5).For NY1Ax03A, maximum

64 LED Steps are available for

1 LED Sentences. TG input can assign this Sentences independently. Each Step can specify one LED Section and enable/disable TG, O1 and O2 output option if TG is set as output. (6). There are maximum

3 channels of LED. Each channel can be assigned one set of programmable PWM square waveform (Flashing) and/or fade-in/fade-out oblique (Ascend/Descend). Every PWM square waveform can be set as different level of 0%~100% amplitude to control the LED brightness, and every oblique has maximum

128 levels variation to generate fade-in or fade-out effect. (7). Only build in an accurate internal oscillator of +/- 3% tolerance, no external R oscillator. (8). TG Input option for input pin. (Mask option) (a). TG input can select Edge/Level, Hold/Unhold and Retrigger/Irretrigger trigger modes. (b). TG input can select CDS+1.5M, CDS, 1.5M pull-low resistor or Floating type. (CDS+1.5M option: Only 1.5M? pull-low resistance at key-pressed, and 300K?+1.5M? in parallel pull- low resistance around 250K? at key-released. CDS option: Floating at key-pressed, and 300K? pull- low resistance at key-released.) NY1A Series (c). TG input can select Debounce time: Long debounce of 10ms for push-button.
