Silicon Laboratories Announces AeroFONE Si4905 Single-Chip Cell Phone
Silicon Laboratories announced the AeroFONE Si4905 single-chip phone, which it claimed to be the industry's most integrated, highest performance, easiest-to-use solution for GSM/GPRS handsets. The AeroFONE Si4905 is based on patent pending innovations enabling the first single-chip phone to integrate the power management unit (PMU), battery interface and charging circuitry, digital baseband, analog baseband and a quad-band RF transceiver in a single monolithic CMOS IC.
Compared to other integrated baseband solutions on the market, the Si4905 single-chip phone reduces component count by 75 percent, board area by 65 percent and manufacturing costs by up to 50 percent. The Si4905 has an integrated digitally-controlled crystal oscillator, which eliminates the need for external VC-TCXO modules used in competing solutions. The Si4905 also integrates 2 Mbits of on-chip SRAM, which enables handset manufacturers to build GSM voice-centric cell phones without the need for external SRAM. The AeroFONE single-chip phone also integrates an ARM9 family-based MCU.
The Si4905 is available in a standard 12x12 mm, lead-free, RoHS-compliant plastic ball grid array (PBGA) package. Pricing is dependent on volume. The Si4905 is sampling now, with mass production scheduled for Q2 2006. An evaluation platform is available for $5,000.
