移動 I/O 擴展器和 QWERTY 鍵盤控制器

ADP5587 是一款 I/O 端口擴展器和鍵盤矩陣，適用于需要大型鍵盤矩陣和擴展 I/O 線路的 QWERTY 型電話。I/O 擴展器 IC 可以在移動平臺中解決主處理器 GPIO 數(shù)量有限的問題。\n\n ADP5587 采用 2 mm × 2 mm?小型封裝，具有足夠的能力處理所有按鍵掃描和解碼工作，并通過 I2C 接口和中斷來標記處理器的按鍵按下和松開操作。ADP5587?使主微處理器無需監(jiān)控鍵盤，從而將電流消耗降至較低，并增加了處理器帶寬。ADP5587?還配有緩沖器/FIFO 和按鍵事件計數(shù)器，借助溢出換行和中斷功能，可處理和跟蹤多達 10 個未處理的按鍵或 GPI 事件 ? 18-GPIO 端口擴展器或 10 × 8 鍵盤矩陣\n? GPIO 可配置為 GPI、GPO 和鍵盤行或列\(zhòng)n? 具有自動遞增功能的 I2C 接口\n? 1.65 V 至 3.6 V 工作電壓\n? 鍵盤鎖功能\n? 開漏中斷輸出\n? 按鍵按下和按鍵松開中斷\n? 支持電平可編程性的 GPI 中斷\n? 可編程的上拉電阻\n? 帶有溢出中斷的按鍵事件計數(shù)器\n? 在復位線路和 GPI 上具有 275 μs 去抖動\n? 1 μA 的典型空閑電流\n? 55 μA 的典型輪詢電流\n? 4 mm × 4 mm LFCSP 封裝\n? 間距為 0.4 mm 的小型 2 mm x 2 mm ;
