JunoTM 04 UR8HC007-004 Zero-PowerTM Input Device and Power Management IC HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY 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). The JunoTM 04 provides continuous operation between 3 and 5V and scans a fully programmable 8 X 16 keyboard matrix.The Zero-PowerTM JunoTM 04 will power down even between key presses. Typical power consumption is less than 1 µA, a first for embedded ICs. The JunoTM 04 is equipped with Semtech’s proprietary protocol developed specifically for RISCbased handheld machines. It interfaces the system via either Asynchronous Serial (UART) or the Serial Peripheral Interface (SPI). The integration of features, many of them programmable, on one IC increases flexibility and reduces component count and cost. 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 bot...
