Modern digital wireless handsets have to function as real communications centers that bring a wide range of "smart" features to the cellular market. These include Web browsing, e-mail, voice memo, answering machine, two-way paging, wireless Personal Data Assistant (PDA) and global positioning system (GPS). Advanced ASIC technology is the key to fulfilling the low-cost, smaller size and weight, high-bandwidth and long battery life requirements of next-generation cellular phones.

To achieve higher levels of integration, a System On a Chip (SOC) approach is needed. The benefits arise from integrating major cores and building blocks while concentrating on lowering power and costs while greatly increasing features and functionality.

Active power management is an essential ingredient in any sophisticated battery-operated device. In cellular phones, it is doubly important to afford as much standby time per battery charge as possible. Ideally, such a system would allow for up to 16 hours of standby while also affording several hours of talk time. Power consumption can be reduced in real-time when cores are clocked at a lower frequency whenever possible. By using such a design's embedded Analog to Digital (A/D) converters, coupled with the Advanced Risk Machine (ARM) microprocessor, the system's power condition can be easily and continuously monitored, and "clocking down" can be implemented when warranted.
