A 32 nm SoC With Dual Core ATOM Processor and RF WiFi Transceiver

An × 86 standard operating system compliant System-on-Chip (SoC) with a dual core ATOM processor and a custom interconnect fabric to enable modular design is presented. The 32 nm SoC includes integrated PCI-e Gen 2, DDR3, legacy I/O, voltage regulators, clock generation, power management, memory controller and RF portion of a WiFi transceiver in a 32 nm high-k/metal-gate RF CMOS process with high resistivity substrate. The integrated RF transceiver for 2.4 GHz 802.11g operation achieves a receive sensitivity of -74 dBm, -8 dBm IIP3 and a transmit output power of 20.3 dBm (-25 dB EVM) at 14% TX RF efficiency.
