Intel Penwell inuti Lava Xolo

Chipworks har tittat inuti den för oss skandinaver relativt okÀnda smartphonen Lava Xolo. Det speciella? Det Àr den första smartphonen byggd pÄ Intels Medfield-plattform.
Telefonen har en Intel basbandprocessor (9811) samt nÄgra enheter frÄn Infineon med mÀrkningarna 1.3 och 15A. Det Àr för Chipworks Àn sÄ lÀnge inte vÀlkÀnda enheter.

Under DRAM:et frĂ„n Elpida sitter Intel Q152C489 – Medfield. Det hĂ€r Ă€r deras Intel Atom Z 2460, producerad med deras 32 nm SoC process och med en klockhastighet pĂ„ 1.6 Ghz.

Chipet har ocksÄ en Intel GPU.

Texas Instruments tillhör vinnarskaran

I enheten finns ocksÄ Texas Instruments WL1283C WiLink 7.0 chip som ger WLAN, GPS, Bluetooth (och BLe), AND, och FM.

Fler chip:
  • Texas Instruments 95031B3 power management IC
  • Texas Instruments 24316DSG charge control and protection IC
  • Texas Instruments TPS61161 LED driver
  • InvenSense gyroscope (MPU3050)
  • Bosch accelerometer (package markings C3H)
  • Honeywell compass (L883)
  • Rounding out the sensing capabilities, the SiRF GSD-4T 9600 GPS chip
  • For near-field communications, the phone employs the NXP PN544 chip
  • The ubiquitous (and top performing) Atmel MXT224 provides the touch screen control.
  • RF Micro Devices RF6261 RF amplifier
  • RF Micro Devices 6561 power management IC
  • RF Micro Devices RF6590 power management IC
  • The 16 GB flash memory is courtesy of the Toshiba THGBM4G7D2GBAIE
  • The 8 Gb lower power DRAM is provided by the Elpida B806482PB
  • The device labeled “1CR 20, 1.3” is an Infineon SP5T / SP3T (seen before in the Samsung S II i9100) main antenna switch with one of its pins connected directly to the phone’s main antenna and feeding into the Murata filter banks and the Infineon PMB5712 RF transceiver.
  • The device marked “1SA 1130” is a diversity switch given that the phone has a clearly labeled diversity antenna attached to the external case. The 15A is an Infineon Single Pole 5 Throw (SP5T) antenna switch also found in the Apple iPhone 4S.
