The Hantek 4032L is an USB-based, 32-channel logic analyzer with up to 400MHz sampling rate and 256MiB memory.

See Hantek_4032L/Info for more details about the device.

Hardware

  • Xilinx Spartan-6 XC6SLX16 CSG324 DIV1225 (FPGA, 14579 logic cells, 2 DDR1/2/3 memory controllers, BGA324)
  • Cypress FX2LP CY7C68013A-100AXC (USB 2.0 HS controller, TQFP100)
  • 2x Micron MT47H64M16HR-25E:H (1Gbit DDR2 SDRAM, BGA)
  • TI TPS51116 (DDR memory power controller)
  • Unknown I2C EEPROM (marking removed, contains FX2 firmware)
  • MXIC MX25L4005 (4Mbit SPI flash, marking removed, contains FPGA bitstream)

Protocol

  • Vendor request is used to reset the engine and flush the buffers
  • Endpoint 2 is used for host-to-device command/parameters transfers
  • Endpoint 6 is used for device-to-host status/data transfers

X denotes "any value" in the following description

Vendor requests

  • bRequest=0xB3, wValue=X, wIndex=X, wLength=0x0A, data={ 0x0F, 0x03, 0x03, 0x03, X, X, X, X, X, X } - restart the engine (reset FPGA, reset FIFOs)
  • bRequest=0xD0, wValue=X, wIndex=X, wLength=0x00 - disable communication (set FIFO reset), not used
  • bRequest=0xD0, wValue=X, wIndex=X, wLength=0x00 - enable communication (clear FIFO reset), not used
