Product Details

Description



Features:

• Typically consumes less than 1 A
• 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-PowerTM 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
• 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 JunoTM versions offer control of internal pointing device


Application

• Jupiter devices/Professional PCs • H/PCs, Web Phones, & G3 erminals

Description

JunoTM 01 UR8HC007-001 is a member of a series of multi-functional companion ICs for Jupiter and other devices running Microsoft® Windows® CE and utilizing RISC-based processors. The IC UR8HC007-001 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-PowerTM JunoTM UR8HC007-001 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 A, a first for embedded ICs.

The JunoTM UR8HC007-001 provides continuous operation between 3 and 5V and scans a fully programmable 8 X 16 keyboard matrix. The IC is equipped with three Zero-PowerTM 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 JunoTM UR8HC007-001 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 UR8HC007-001 increases flexibility and reduces component count and cost.
