ISG4100x Datasheet | Imagis Semiconductor

Imagis Co., Ltd. Preliminary Datasheet 1. Overview 1.1. Description The ISG4100x Mobile Key Scan I/O panion is a dedicated device to unburden a host processor from scanning a matrix-addressed keypad. It municates with the host through an I2Cpatible or SPI-patible access bus interface. An interrupt output is available for signaling key-press events. In the I2C munication, frequencies up to 400KHz bus speed are supported. In the SPI munication, frequencies up to 10MHz bus speed are supported. ISG4100x supports a predefined set of mands. These mands enable a host device to keep control over all functions. 1.1.1. Block Diagram of ISG4100I .DataSheet.net/...
