Juno® 01 UR8HC007-001 Extremely Low-power Input Device and Power Management IC
HID & SYSTEM MANAGEMENT PRODUCTS, MULTI-FUNCTION IC FAMILY DESCRIPTION The Juno® 01 UR8HC007-001 is a member of a series of multifunctional companion ICs for Jupiter-class devices and other devices using 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 extremely low-power Juno® 01 powers down even between key presses. Semtech's proprietary circuitry 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® 01 provides continuous operation between 3V and 5V and scans a fully programmable 8 X 16 keyboard matrix. The IC is equipped with three extremely lowpower 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 MouseWheels. In addition, the Juno® 01 offers 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 component 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 Volts and 5 Volts · Offers unique power management capabilities that work in harmony with Windows® CE power modes · Always runs in "Stop" mode without data or event loss · Provides three extremely lowpower PS/2 ports for the hot-plug connection of external keyboards/mice & internal mouse, including MouseWheels · Uses proprietary circuitry, so "Stop" mode is entered even when PS/2 devices are connected and active · Available in 1.7mm high package to accommodate slim designs APPLICATIONS · Jupiter devices/Professional PCs · H/PCs, web phones, & G3 terminals · GPIO pins provide interrupt at both falling and rising edge of signals, ideal for lid functions, power, ring indicators, docking signals, battery measurement, etc. · Has additional GPIO available for LEDs, switches, etc. · Offers internal control of LCD brightness/contrast, audio, etc. as well as four 10-bit A/D channels for power management monitoring · Cost-effective, reducing overall system costs by integrating features that would typically require multiple additional components · Provides programmable features that allow for maximum design differentiation without customization · Other Juno® versions offer control of internal pointing device PRELIMINARY
