---+!! !MobiBLU Information %TOC% ---++ Known Player Composition * Sigmatel 3520 chip (STMP3520 B144E-TA6 U00030 0538; see SDK information for what this means); see also: SigmaTelSTMP3xxx * Features include USB 2.0 PHY, batter charger, and 18 bits audio codec. * This chip contains a Motorola DSP 56004 with a filter coprocessor for FIR and IIR filters. The core runs at 75.6 MHz (at most) at Vdd > 1.92 V. * [[http://paginas.terra.com.br/informatica/midireview/MIDI%20Japan%20MP3_arquivos/stmp3500_reference_sch_revb.pdf][PDF Chip Schematics]] - Diagrams of actual components of chips (copy and paste link into browser) * [[http://www.eetchina.com/ARTICLES/2005NOV/PDF/App_Brief2_MS_Drive_3_1.PDF][PDF Chip information]] * [[http://sigmatel.com/products/portable/audio/stmp3500.aspx][More general chip information]] - A webpage displaying how chips interact with other DAP components * [[http://www.sigmatel.com/documents/2005q4-portable_soc_guide.pdf][PDF More general chip information]] - Feature chart comparing different chip capabilities * [[http://www.diva-portal.org/diva/getDocument?urn_nbn_se_liu_diva-7114-1__fulltext.pdf][PDF Technical chip information]] - A guide assessing different parts of a DAP * [[http://www.incmicro.com/support/download/downDownload.asp?pds_no=635][PDF SDK information]] - Provided by Sigmatel; identifies developer software and boards as well as some chip information * [[http://home.tula.net/nickit/rover.htm][Custom FW]] - Development of custom FW, tools and FW base for any Sigmatel stmp35xx. * Samsung 543 NAND memory (SAMSUNG 543 K9W8G08U1M PCBO CAI643CA) * [[http://www.tranzistoare.ro/datasheets/700/389215_DS.pdf][Memory datasheet]] - Pages upon pages of information on this memory chip * Li-ion battery (PR-622020 5J0600021 I484ER01AI) * Not much is really known about this battery. In the DAH-1500 and DAH-1500s players, they use a cell battery, but the battery in this model is a bag-type. One DAH-1500i however did have a cell (a 180mAh), so the battery seems to vary per player. No idea about who makes this particular one. * [[http://www.anythingbutipod.com/archives/2005/12/guide-to-disassembling-the-mobiblu-dah1500i.php][Disassembling the DAH-1500i]] - Has battery specs as well as user contributions ---++ Photos of Internal Components | *Front View* | *Back View* | | <a href="%ATTACHURLPATH%/Front_Chip.jpg"><img border="0" src="%ATTACHURLPATH%/Front_Chip_Small.jpg" alt="Front_Chip_Small.jpg" width="278" height="697" /></a> | <a href="%ATTACHURLPATH%/Back_Chip.jpg"><img border="0" src="%ATTACHURLPATH%/Back_Chip_Small.jpg" alt="Back_Chip_Small.jpg" width="271" height="694" /></a> | | [[%ATTACHURLPATH%/Front_Chip.jpg][View Large Version]] | [[%ATTACHURLPATH%/Back_Chip.jpg][View Large Version]] |
