ZEROPLUS Logic Cube LAP-C(16032)

ZEROPLUS Logic Cube LAP-C(16032)

The ZEROPLUS Logic Cube LAP-C(16032) is a USB-based, 16-channel logic analyzer with up to 100MHz samplerate.

See ZEROPLUS Logic Cube LAP-C(16032)/Info for some more details (such as lsusb -vvv output) on the device.

See also ZEROPLUS Logic Cube LAP-C series for an overview of all devices in the LAP-C series.

Hardware

• ZEROPLUS ZP-322MC-5 (probably a custom ZEROPLUS ASIC)
• Genesys Logic GL660USB (USB2.0 to IEEE-1284 / DMA bridge)
• Cypress CY7C1347G-250AXC (4Mbit pipelined sync SRAM, 250MHz)
• 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)
• Texas Instruments SN74LVT16245B (3.3V ABT 16bit bus transceivers with 3-state outputs)
• National LM348M (quad 741 op-amp)
