CPU


   * ARM946E-S (main processor) http://www.arm.com/products/CPUs/ARM946ES.html
   * ARM7TDMI (secondary processor)http://www.arm.com/products/CPUs/ARM7TDMI.html
   * ARM ARM (encodings and opcode descriptions through ARM arch v6): [[http://www.google.com/search?q=arm+ddi+0100e] 

Both processors are on the same die (see Chips for more details).

Memory


   * M69AB048 (main memory, 2Mx16) http://www.st.com/stonline/books/ascii/docs/9866.htm (wrong but similar)
   * Fairchild/Fujitsu MB82DBS02163C-70L "Mobile FCRAM / Fast Cycle RAM" (main memory, 2Mx16) http://edevice.fujitsu.com/fj/DATASHEET/e-ds/e511429.pdf 

Audio amp


   * LM 4880M http://www.national.com/ds/LM/LM4880.pdf 

LCD (bottom)


   * LS030B7DD12F 49N07020132 

DS won't boot when backlight is not attached. To trick the DS in booting anyways, use a resistor of 6K8 or something.

Touch Screen controller


   * TSC2046 () http://focus.ti.com/docs/prod/folders/print/tsc2046.html
   * AKM4148AVT (on version 2 of PCB) http://www.asahi-kasei.co.jp/akm/en/product/ak4181a/ak4181a.html 

Real Time Clock


   * Teensy-tiny 8 pin chip marked 110 408 458, hooked up to a 32.768 KHz crystal ftp://ftp.sii.co.jp/pub/ic/speed_dt/dt_sht_e/assp/S35190A_E.pdf 

Save EEPROM on cartridges


   * SPI compatible 


Firmware


   * M45PE20
