Juno TM UR8HC007-001 Input Device and Power Management panion IC for Jupiter Devices HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY DESCRIPTION Juno TM 01 is a member of a series of multi-functional panion ICs for Jupiter and other devices running Microsoft® Windows® CE and utilizing RISC-based processors. The IC interfaces the system via either asynchronous serial or the Serial Peripheral Interface (SPI) and provides keyboard scanning, special general purpose I/O (GPIO) and unique system power management capabilities. The Zero-Power TM Juno TM will power down even between key presses. Semtech’s proprietary circuitry (patent pending) allows the IC to power down even when PS/2 devices are connected and active. Typical power consumption is less than 1 µA, a first for embedded ICs. The Juno TM provides continuous operation between 3 and 5V and scans a fully programmable 8 X 16 keyboard matrix. The IC is equipped with three Zero-Power TM PS/2 ports for the hot-plug connection of an external PS/2 keyboard and mouse as well as an internal PS/2 mouse, including those with Mouse Wheels. In addition, the Juno TM offers special general purpose I/O (GPIO), ideal for use for lid functions, power switches, ring indicators, docking signals, battery measurement, LEDs, etc. The integration of Features , many of them programmable, on one IC increases flexibility and reduces ponent count and cost. Features - Typically consumes less than 1 µA - Scans a fully programmable 8 X 16 matrix that supports Japanese, English and European keyboards - Operates continuously between 3 and 5 Volts - Offers unique power management capabilities that work in harmony with Windows® CE’s power modes - Always runs in “Stop” mode without data or event loss - Provides three Zero-Power TM PS/2 ports for the hot-plug connection of external keyboards/mice & internal mouse, including Mouse Wheels - Uses proprietary circuitry, so “Stop” mode is entered even when PS/2 devices are connected and active -...
