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)

- 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
