HTR3316
2.5V~5.5V电源供电。16个IO端口中的任何一个都可以配置为LED模式或GPIO模式。
2.5V~5.5V主机电源用电。16个IO端口处中的其中一款都是就能够以硬件标准配置为LED形式 或GPIO形式 。除此以外,其中GPIO都是就能够以分次硬件标准配置为输进或导出。通电后,16个IO端口处号显卡配置单初始为GPIO打印打印输出电压,初始工作模式随着AD0和AD1取决于。大多数显卡配置单为投入的IO端口处号都将不间断监视器工作模式发生改变,并拥有8μs的防抽动日子,IO口的发生改变由INTN打印打印输出电压指令。当GPIO工作模式依据I2C主板接口被导入时,INTN打印打印输出电压被移除。当IO网口配备为LED摸式时,是就可以用I2Cusb接口将LED驱程器的直流电设为在0~IMAX间,并是就可以以该值除256伺服电机行直线调光。默认值最多直流电(IMAX)为37mA,可在多线程在保持寄存器中变化IMAX。HTR3316提供QFN4×4-24L封装。

引脚号 | 称呼 | 实用功能 |
1~4 | P1_0~P1_3 | GPIO mode default, input or output (push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode.设制GPIO基本状态,插入或所在(推挽设计),上电设制状况由AD1和AD0直接决定。可设制为LED基本状态。 |
5~8 | P0_0~P0_3 | GPIO mode default, input or output (open-drain (default) or push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode.默许GPIO格局,放入或的输出(开漏设备构造(默许)或推挽设备构造),上电默许程序由AD1和AD0影响。可使用为LED格局。 |
9 | GND | Ground. 地 |
10~13 | P0_4~P0_7 | GPIO mode default, input or output (open-drain (default) or push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode.缺省GPIO,复制粘贴或輸出(开漏组成部分的(缺省)或推挽组成部分的),上电缺省阶段由AD1和AD0考虑。可装置为LED玩法。 |
14~17 | P1_4~P1_7 | GPIO mode default, input or output (push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode.缺省GPIO,模拟输出或模拟输出(推挽结构的), ,上电缺省模式,由AD1和AD0决心。可设立为LED模式,。 |
18 | AD0 | I2𓂃C device address, connect to VCC or GND,and control the default state of GPIOs (see table 1)。 I2C器件地址选择,接VCC或GND,并设置GPIO状态(见表1)。 |
19 | SCL | I2C serial clock. I2C时钟 |
20 | SDA | I2C serial data. I2C数据 |
21 | VCC | Power supply. 电源开关发送端. |
22 | INTN | Interrupt output pin, open-drain, need external pull-up resistor; active low.中止輸出,开漏机构,需外界上拉电阻值;低合理 |
23 | RSTN | Hardware reset pin, active low; internal 100 kΩ (typical) pull-down resistor.硬件软件归位,低为归位;内属下拉100 kΩ(一般值)电阻值 |
24 | AD1 | I2🐽C device address, connect to VCC or GND,and control the default state of GPIO (see table 1)。 I2C器件地址选择,接VCC或GND,并设置GPIO状态(见表1)。 |
EP | GND | Provides both electrical and thermal connection from the device to the board. Connect to the system ground. 地线。 |
