CWAV USBee SX
|Min/max voltage||max. 5.5V|
|Threshold voltage||Fixed: VIH=1.4V, VIL=0.8V|
The USBee SX is a USB-based, 8-channel logic analyzer (and signal generator) with up to 24MHz sampling rate.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See CWAV USBee SX/Info for some more details (such as lsusb -vvv output) on the device.
- Main chip: Cypress CY7C68013A-56PVXC (FX2LP)
- Note: Older versions used the Cypress CY7C68013-56PVC (FX2), which is different in some ways (e.g. less SRAM)
- 3.3V voltage regulator: ST LD33
- I2C EEPROM: Microchip 24LC01B
- Crystal: 24MHz

Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
However, for those interested in this, someone else has already decoded most of it.
