Description

The JunoTM 04 UR8HC007-004 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 UR8HC007-004 integrates control of any 4-wire or 8-wire resistive touch screen, keyboard scanning, unique powe management capabilities, and plenty of General Purpose Input / Output (GPIO).

The JunoTM 04 UR8HC007-004 provides continuous operation between 3 and 5V and scans a fully programmable 8 X 16 keyboard matrix.The Zero-PowerTM JunoTM 04 UR8HC007-004 will power down even between key presses. Typical power consumption is less than 1 A, a first for embedded ICs.

The JunoTM 04 UR8HC007-004 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 UR8HC007-004 increases flexibility and reduces component count and cost.
