The Saleae Logic clone is USB-based logic analyzer with 8-channel and up to 24MHz sample-rate.

Looks like a clone of the Saleae Logic. It's USB-device ID is: 0925:3881


In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.

Hardware

  • Main chip: Cypress CY7C68013A-56LTXC (FX2)
  • Input buffer(?): NXP 74LVC245A (complete marking: NXP LVC245A KX44549 TXD613F)
  • 32kByte I2C EEPROM: Atmel AT24C256 (marks: ATML H612 02DM B A2C9JF)
  • voltage regulator: Torex Semiconductor XC6206 (marks: "6206A 1625/33")
  • 24MHz crystal: K24.000

Protocol

Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
