Revision as of 04:11, 20 December 2022
Specifications
- Includes (2) 0.3 Megapixel VGA Cameras
- 240MB(+16MB probably reserved for wear leveling purposes (e.g. replacing bad blocks)) Internal Flash Memory - Samsung kmapf0000m-S998 MOVI NAND - MMC Interface
- 16MB RAM - NEC uPD 46128512AF1 - DDR SRAM or a Fujitsu 128-Mbit FCRAM 82DBS08164D-70L (datasheet: http://edevice.fujitsu.com/fj/DATASHEET/e-ds/e511454.pdf mirror:Media:E511454.pdf
- (2) 256 x 192 3.25 Inch Displays, one of which has a resistive touch screen
- Backwards compatible with Nintendo DS games but not GBA games due to the lack of a gameboy cartridge port.
- Integrated ARM7/ARM9 cores clocked at 133mhz in real mode and downclocked to 66mhz for compatibility mode.
- PAIC3000D Touchscreen and sound controller - possibly a TI codec: TSC2117
- Mitsumi (MM3317A) or TI 72071B0 or NEC UPD68878Y04 - Power management controller. (The charger circuit itself is fully analog, and closer to the charging port.)
- SD/SDHC Card slot
- WiFi_Module with integrated 128KB SPI Flash for NVRAM, WiFi settings
- BPTWL - Microcontroller based on a NEC uPD78F0500 used as "Super I/O"/"Embedded controller", used for battery charge level monitoring, volume settings, power-on sequencing of various modules (SoC, Wifi, ...), basic troubleshooting of the power supplies. Controls the status LEDs in the hinge.
Hardware Revisions
DSi
- board C/TWL-CPU-01 (Original rev, all pictures below)
- CPU: TWL. The latest date code picture I could find online was "0836 1m" as shown below, however other pictures with CPU covered show the NAND codes as late as 916, so...
- Suspect this is the only board where WiFi chip is available in Hybrid games like CookingCoach
- Wireless card DWM-W015
DSi RevA
- board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?)
- CPU: TWL A. Mine is "0940 2m". My US Serial # is ~ TW71848???[5]. If yours is earlier, please update this.
DSi XL
- board C/UTL-CPU-01
- CPU is TWL A
- Wireless card DWM-W024
