DEM-3000X

The DEM series are prototype models used by Sony for development (hence why D in DEM) before the PDEL series (which resembles more closely to the production PCH-1XXX series).

= Short description =

Unknown white prototype model

DEM-3000H
User Jerry Yin of AssemblerGames found a couple of DEM-3000H units and gave a teardown with photos of the process (dead link).

Map






The following is an attempt to map key areas of interest on the DEM-3000X device. All items appear in PCH units (in different locations) unless otherwise specified.


 * 1) Wifi/BT module. There exists an ANATEL filing but nothing with the FCC since Sony decided to certify the entire PCH motherboard instead.
 * 2) Power distribution network. Ceramic chip, analog logic assumed.
 * 3) Decoupling network for Kermit as well as P1P40167 clock synthesizer IC and a 27MHz crystal.
 * 4) Back camera connector.
 * 5) eMMC storage, 4GiB.
 * 6) Syscon and related crystals. Chip is labeled "D79F0109 ES1.0 10301M001 MALAYSIA" and is likely a Renesas IC with a custom RISC based CPU core.
 * 7) Accelerometer. Kionix KXTC9
 * 8) Top: ST32F100B6 microcontroller. On PCH units it's a slightly different model (ST32P10S0E, undocumented). Likely used to interface with the sensors and/or controller. Left: unknown, probably some sensor. Right: Gyroscope, ST 3GA51H model.
 * 9) MAX11615EEE analog to digital converter? Maybe connected to #18 connector on the backside. Not found on PCH models but found in PDEL.
 * 10) Front panel connector. Slightly longer than PCH models likely due to different panels. Probably also contains front camera interface as well.
 * 11) Start/Select buttons. Not found on PCH models (it's on the side-board).
 * 12) Power management. Same network found on PCH units with extra chips for charging/battery fuel gague.
 * 13) Boot-up LEDs. Same as in PDEL units. Connected to GPIO.
 * 14) Kermit SoC, pre-production version. Labeled "Toshiba T9ML6TLxxxx JAPAN 105xxxx A29590" (xxxx are unclear from picture). Earlier model than the FCC filing for PDEL which had a "T9ML7MBG-S".
 * 15) MIPI DSI 3 lanes for front panel.
 * 16) MIPI DSI 4 lanes for HDMI conversion IC (to #24). Only found on VitaTV and PDEL units.
 * 17) Unknown IC, cannot find mapping to PCH unit.
 * 18) Connector to back touchpad.
 * 19) Audio codec IC. Labeled "WM1803E 06ABRT4". On top right (outside box) is an IC related to the antennas.
 * 20) Unknown connector pads.
 * 21) Battery for CP.
 * 22) mini PCIe connector for CP daughterboard. Does not follow PCIe signal interface.
 * 23) Unknown transistor/logic network.
 * 24) MIPI DSI to HDMI translation chip. ADV7533 model.
 * 25) Mini HDMI connector
 * 26) mini-USB connector from the CP.
 * 27) eMMC storage for CP
 * 28) Left: EPSON RX-4581NB real-time clock (labeled "R4581 EK416C"). Right: PIC16F724-I/ML microcontroller (low power). Both likely powered by battery (#21) and are used to ensure CP RTC is never reset.
 * 29) Unknown IC
 * 30) Unknown network
 * 31) DRAM for CP. 256MB. Labeled "Samsung K4X2G323PC-8GD8"
 * 32) CP processor. Labeled "... 1028KU603 JAPAN ARM". PDEL units are labeled "KD77630AF1 EM1-S 1141KU601 JAPAN ARM". Both are likely the same chip from Renesas.
 * 33) Left: USB transceiver. SMSC USB3315 model. Right: USB hub. SMSC USB2512B model. Above that: crystal for USB. Allows CP USB port to export an interface to CP processor as well as Kermit.
 * 34) Unknown. Connected to USB hub IC.
