Hardware

Hardware between the LAP-C series devices is very similar and includes:

  • ZEROPLUS ZP-322MB-5 or ZP-322MC-5 (probably a custom ZEROPLUS ASIC)
  • Genesys Logic GL660USB (USB2.0 to IEEE-1284 / DMA bridge)
  • Cypress pipelined sync SRAM, varies by model:
    • CY7C1347G-250AXC 4Mbit, 250MHz (eg, 16032)
    • CY7C1480V33-200AXC 72Mbit, 200MHz (eg, 322000)
  • National LM2596 (SIMPLE SWITCHER power converter 150 kHz 3A step-down voltage regulator)
  • Microchip 93LC46B (1K EEPROM)
  • DV4128B (probably also a custom ZEROPLUS chip)
  • Pericom PI74FCT245TSE (fast CMOS octal bidirectional transceivers)
  • 1-2 Texas Instruments SN74LVT16245B (3.3V ABT 16bit bus transceivers with 3-state outputs)
  • National LM348M (quad 741 op-amp)
