HT1625
HT1625 is a peripheral device specially designed for I/O type MCU used to expand the display capability. The max. display segment of the device are 512 patterns (64x8). It also supports serial interface, buzzer sound, watchdog timer or time base timer functions. The HT1625 is a memory mapping and multi-function LCD controller. The software configuration feature of the HT1625 make it suitable for multiple LCD applications including LCD modules and display subsystems. Only three lines are required for the interface between the host controller and the HT1625. The HT162X series have many kinds of products that match various applications.
HT1625 是專為 MCU 用于擴展顯示功能的 I/O 類型的外圍設備。最大。顯示部分是設備的 512 模式 (64 x 8）。它還支持串行接口、 蜂鳴器聲音、 看門狗定時器或時間基準定時器函數。HT1625 是一個內存映射和多功能液晶顯示控制器。HT1625 的軟件配置功能使其適用于多種 LCD 應用包括 LCD 模塊和顯示子系統。只有三條線都需要主機控制器和 HT1625 之間的接口。HT162X 系列有許多種類的產品相匹配的各種應用。
