The Sysclk LWLA1034 is a USB-based, 34-channel logic analyzer with up to 125MHz sampling rate.
See Sysclk LWLA1034/Info for more details (such as lsusb -v output) about the device.
Hardware
- Altera EP2C5Q208C8N (Cyclone II) FPGA
- Cypress CY7C68013A-56 (FX2) USB interface chip
- Cypress 256k×36 SRAM (likely a CY7C1361C-133AXC or similar)
- STC15F104E 8051-based microcontroller
The not-installed 10-pin connector between the USB socket and the large capacitor seems to connect to the JTAG pins of the FPGA.

Software
Firmware
We have received permission from the vendor to distribute the FPGA bitstreams with sigrok. Thus, the bitstreams are now included in the sigrok-firmware module.
- The FX2 firmware is loaded from an EEPROM on the board, so that the final USB device descriptor is immediately available on power-up.
- Endpoint 4 is used exclusively for loading a new bitstream into the FPGA.
- Endpoint 2 is used for sending commands to the FPGA firmware, with responses (if any) coming in from endpoint 6.
Reverse engineering of the vendor's custom protocol has been completed. See Sysclk LWLA1034/Protocol for the documentation.
