Juno TM 04 UR8HC007-004 Zero-Power TM Input Device and Power Management IC HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY DESCRIPTION The Juno TM 04 is a member of a series of input device and power management panion ICs for RISC-based portable systems. On a single IC, the Juno TM 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 Juno TM 04 provides continuous operation between 3 and 5V and scans a fully programmable 8 X 16 keyboard matrix.The Zero-Power TM Juno TM 04 will power down even between key presses. Typical power consumption is less than 1 µA, a first for embedded ICs. The Juno TM 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 ponent 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 both falling and rising edge of signals, ideal for lid functions, power, ring indicators, docking signals, battery measurement, etc. APPLICATIONS - Jupiter-class devices - Professional H/PCs PIN ASSIGNMENTS R2 R3 R4 R5 R6 R7 C0 C1 C2 C3 C4 C5 C6 C7 LEFT0/GIO60 LEFT1/GIO61 LEFT2/GIO62 LEFT3/GIO63 RIGHT0/GIO64 RIGHT1/GIO65 - 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...
