The MCU123 Saleae Logic clone is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.

It is a clone of the Saleae Logic. It's also very similar to the MCU123 USBee AX Pro clone minus the different USB vendor/device IDs.

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

See MCU123 Saleae Logic clone/Info for more detailed information on the device.

Hardware

  • Main chip: Cypress CY7C68013-56PVC (FX2)
  • Input buffer: NXP 74HC245 (markings: "NXP HC245 2A7K508 UnD2 18E")
  • 256-byte I2C EEPROM: Atmel AT24C02 (markings: "ATMEL211 24C02N SU27 D")
  • 3.3V low-dropout voltage regulator: Advanced Monolithic Systems AMS1117-3.3 (markings: "AMS1117 3.3 HT240E")
  • 24MHz crystal: 24.000

Protocol

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