Mobile I/O Expander and QWERTY Keypad Controller

GENERAL DESCRIPTION The ADP5588 is an I/O port expander and keypad matrix designed for QWERTY type phones that require a large keypad matrix and expanded I/O lines. I/O expander ICs are used in mobile platforms as a solution to the limited number of GPIOs available in the main processor. In i

移动I/O扩展器和QWERTY键盘控制器

ADP5588是一款I/O端口扩展器和键盘矩阵，适用于需要大型键盘矩阵和扩展I/O线路的QWERTY型电话。I/O扩展器IC可以在移动平台中解决主处理器GPIO数量有限的问题。\n\n ADP5588采用4 mm × 4 mm小型封装，具有足够的能力处理所有按键扫描和解码工作，并通过 I2C® 接口和中断来标记处理器的按键按下和松开操作。它使得主微处理器无需监控键盘，从而将电流消耗降至较低，并增加了处理器带宽。它还配有缓冲区/FIFO和按键事件计数器，借助溢出换行和中断功能，可处理和跟踪多达10个未处理的按键或GPI事件。\n\n ADP5588具有键盘锁功能，可以选择在按 • 18-GPIO 端口扩展器或 10 × 8 键盘矩阵\n• GPIO 可配置为 GPI、GPO 和键盘行或列\n• 双光传感器输入（C8 和 C9）\n• I2C 接口\n• I2C 寄存器读取自动递增\n• 1.8 V 至 3.0 V 工作电压\n• 键盘锁功能\n• 开漏中断输出\n• 按键按下和按键松开中断\n• 支持电平可编程性的 GPI 中断\n• 可编程的上拉电阻\n• 带有溢出中断的按键事件计数器\n• 在复位线路和 GPI 上具有 50 μs 去抖动\n• 1次按键时，典型的空闲电流为 1 μA，典型的轮询电流消耗为 55 μA。\n• 4 mm × 4 mm 小 LFCS;
