MCU123 USBee AX Pro clone
|Min/max voltage||-0.5V — 5.25V|
|Threshold voltage||Fixed: VIH=2.0V—5.25V, VIL=-0.5V—0.8V|
The MCU123 USBee AX Pro clone is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.
It is a clone of the CWAV USBee AX-Pro, but it doesn't have analog (only 8-channel digital) sampling capabilities. It's also very similar to the MCU123 Saleae Logic clone minus the different USB vendor/device IDs.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See MCU123 USBee AX Pro clone/Info for more detailed information on the device.
- Main chip: Cypress CY7C68013A-56PVXC (FX2LP)
- Input buffer: NXP 74HC245 (markings: "NXP HC245 2A7K508 UnD2 18E")
- 256-byte I2C EEPROM: Atmel AT24C02 (markings: "ATMEL218 24C02N SU27 D")
- 3.3V low-dropout voltage regulator: Advanced Monolithic Systems AMS1117-3.3 (markings: "AMS1117 3.3 HT240E")
- 24MHz crystal: 24.000
Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
