UR8HC007-0A4 Overview
The JunoTM A4 is a member of a series of input device and power management panion ICs for RISC-based portable systems. On a single IC, the JunoTM A4 integrates control of any 4-wire or 8-wire resistive touch screen, keyboard scanning, unique power management capabilities, a direct PS/2 port and plenty of General Purpose Input / Output (GPIO). The JunoTM A4 provides continuous operation between 3V and 5V and scans a...
UR8HC007-0A4 Key Features
- Typically consumes less than 1µA
- Scans an 8 x 16 keyboard matrix that supports Japanese, English and European keyboards
- Interfaces any four-wire or eightwire 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
- Provides a direct Zero-PowerTM PS/2 port for the hot-plug connection of an external keyboard or mouse
- Uses proprietary circuitry, so “Stop” mode is entered even when PS/2 device is connected & active
- GPIO pins provide interrupt at both falling and rising edge of signals, ideal for lid functions, power, ring indicators,
- Has additional GPIO available for LEDs, switches, etc
