Infineon Technologies AG announced that the first E-GOLDvoice chip produced in Dresden, Germany worked at the first attempt and has already been used to make phone calls on GSM networks. E-GOLDvoice is a mobile telephony chip that measures 8-by-8mm2. The chip is said to reduce the materials costs of a complete cellphone.

"The successful chip operation is proof of our innovative integration strategy to put existing functionality in established technologies onto a single-chip to bring down costs and reduce space requirements." said Hermann Eul, member of the Infineon management board and head of the communication solutions business group. "With E-GOLDvoice and fewer than 50 other electronic components, its now possible for the first time to manufacture cellphones that fit their entire GSM functionality onto a circuit board measuring four square centimeters."

Manufactured using 130nm CMOS technology, the GSM chip is said to be the first in the world to integrate on a single chip a baseband processor, the RF part that carries voice between the handset and the base station, SRAM memory and power management. Infineon revealed that the previous power management chip alone took up an area measuring 7-by-7mm2.

Volume manufacturing of low-cost mobile phones based on Infineons current ULC1 (ultra low-cost, first generation) platform with the E-GOLDradio chip has been underway for several months now, and preparations are now in progress for production using the ULC2 (second generation) platform centered on the E-GOLDvoice chip. Engineering samples are expected to be available in July.
