Ultra low-cost GSM single-chip with successful live phone call

12 July 2006 Telecoms, Datacoms, Wireless, IoT

Infineon Technologies' E-GOLDvoice chip, claimed to be the most highly integrated chip for mobile telephony, has already been used to make phone calls on GSM networks. The device combines all of a mobile phone's essential electronic components into an area measuring 8 x 8 mm². With E-GOLDvoice and fewer than 50 other electronic components, Infineon says it is now possible for the first time to manufacture mobile phones that fit their entire GSM functionality onto a circuit board measuring 4 cm². Manufactured using 130 nm CMOS technology, the GSM chip integrates not just the baseband processor and the RF part that carries voice between the handset and the basestation, but also the SRAM memory and power management. Previously, the power management chip alone took up an area measuring 7 x 7 mm² according to the manufacturer.
