of the Main-PCB (printed circuit board) with three
major Integrated Circuits:
Hynix HY57V281620A: 8M * 16bits CMOS SDRAM
Fujitsu 29LV400TC: 256k * 16bits CMOS FLASH-ROM
Philips CA4885: unknown (probably power supply)
of the Main-PCB with the POMAP1509E dual-core processor of the Texas
Instruments OMAPô family.
It is supported by a Toshiba TC58V64A 8M * 8bits CMOS NAND EEPROM and some power supply components.
The huge connector below the OMAPô matches with a standard SD Memory Card.
