   * 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.

   * 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.
