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.
