CPU : Hitachi SH-3 CPU, 133 Mhz Clock
Sound Chip : Yamaha YMZ770C-F
Other Chips (Based on Ibara) :

  • Altera Cyclone EP1C12F324C8 FPGA (i think used as Video-DSP and SD-RAM Controller),
  • K9F1G08U0A 128M x 8 Bit NAND Flash Memory,
  • 1x MX29LV160BBTC-90 Flash Memory
  • and, 2x MX29LV320ABTC-90 Flash ICs (space for up to 2 more Flash ICs is not used),
  • 1xMT48LC2M32B2-6 SDRAM,
  • and 2x MT46V16M16. LA4708 Audio amplifier.

Notes : The CV1000-D is a direct upgrade of the Cave CV1000B board, the main differences seem to be;

  • Chip U1 : IS42S32400D 128Mb SDRAM @ 166mhz (standard SH3 has MT48LC2M32 64Mb SDRAM)
  • Chip U4 : 32Mbit Spansion S29JL032H (standard SH3 has a 16Mbit Spansion S29AL016D.

No Lithium Battery
