SH1201 Datasheet | SEMTECH

ION The Pixi Point® SH1201 mouse encoder is a cost-effective, highfunctionality IC that interfaces a force-stick sensor to a PS/2 or serial port. Ideal for laptop or palmtop use, the low-power Pixi Point® uses an advanced .. algorithm for enhanced motion control. The IC can be configured as a standard 3-button mouse or as a wheel mouse. The IC provides an extra port for hot-plug connection of an external PS/2 mouse, including one with wheel function. The embedded sensor and the external device can operate concurrently. The Pixi Point® includes a signal conditioning circuit for a low cost, simple and real estate-saving implementation. Just a few lowtolerance external ponents are needed. Typically consuming less than 4.5 m A, the Pixi Point® is ideal for battery-operated systems. PS/2 munication is bidirectional at 10 Kbps. The Pixi Point® returns up to 100 mouse reports per second, and is patible with the standard twobutton mouse protocol, the standard three-button mouse protocol, and the standard wheel mouse protocols. It implements all mands from and to the system (as defined in the IBM PS/2 mouse munication protocol). The Pixi Point® also implements most of the IBM force stick extended mands, and works with most IBM force stick drivers. Features - Advanced motion control algorithm provides accurate cursor control - Can be configured for PS/2 or RS232 serial munication with the host - Can be configured as a standard 3-button mouse or a wheel mouse - plies with the Microsoft® Plug and Play External Device specification - Click (select), double-click (execute), and slow drag are implemented in the IC - no special driver support is required - Provides built-in profiles to interface popular force-stick sensors from several manufacturers APPLICATIONS - Notebooks/laptops - Handhelds PIN ASSIGNMENTS - Keyboards - Instrumentation - Supports hot-plug connection of a standard external PS/2 mouse, with or without wheel function - Works with standard Windows® mouse drivers - Works...
