It has no firmware on board; this must be uploaded when the unit is powered on. sigrok uses the open-source [[fx2lafw]] firmware for this.

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 more detailed information on the device.

Hardware

  • 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

Protocol

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.
