DESCRIPTION
The JunoTM 04 is a member of a series of input device and power management companion ICs for RISC-based portable systems. On a single IC, the JunoTM 04 integrates control of any 4-wire or 8-wire resistive touch screen, keyboard scanning, unique power management capabilities, and plenty of General Purpose Input / Output (GPIO).

FEATURES
• Typically consumes less than 1µA
• Scans an 8 x 16 keyboard matrix that supports Japanese, English and European keyboards
• Interfaces any four- or eight-wire resistive touch screen
• 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
• 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
• Provides programmable features that allow for maximum design differentiation without customization
• Cost-effective, reducing overall system costs by integrating features that would typically require multiple components
• Available in 80-pin 13 x 13 mm, 1.7mm high package to accommodate slim designs
