Zilog ZHX3403MA012THTR

The ZILOG ZHX3403, designed for mobile phones, pagers, and PDAs, is the smallest, lowest-power, and most feature-rich transceiver in its class. It employs proprietary AlwaysOn™ technology, allowing the transceiver to "listen" for IrDA communications at a typical current of 6μA, with negligible impact on battery life when the default mode is enabled. Once another IrDA device is detected, the typical low receive current consumption during communication is 100μA (MIR). Its ultra-slim form factor of 7.3mm (L) × 2.8mm (W) × 1.9mm (H) allows placement in virtually any compact device, requiring only two external components to minimize application circuit footprint. The transceiver supports IrDA-Data MIR mode at a data rate of 1.15 Mbits/s — 10 times that of typical PDA and mobile phone solutions — enhancing users' ability to share photos, MP3 files, PDFs, and other large files. It integrates an IRED emitter, PIN photodiode, and a unique driver/control ASIC in a single package. In addition, it features a shutdown control function that reduces current consumption to a typical 0.1μA.
