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.
CWAV, Inc. has been closed and no longer sells the USBee test pods (has chosen to go out of business effective September 10, 2015). But there are a lot of clones, like MCU123 USBee AX Pro clone. Just search for 24mhz 8ch logic analyzer on http://ebay.com/ or http://aliexpress.com/ for one (usually under $10).
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.
