The mcupro Logic16 clone is a USB-based, 16-channel logic analyzer with 100/50/32/16MHz sampling rate (at 3/6/9/16 enabled channels).

This is a clone of the Saleae Logic16.

See mcupro Logic16 clone/Info for more details (such as lsusb -v output) about the device.

Hardware (Actel variant)

Hardware (Cyclone variant)

Hardware (2015-01-08 variant)

The PCB is marked "Saleae Logic 16 By MCUPro 2015-1-8". Readily identifiable by the irregular PCB traces, and switching power supplies. This comes in a different case, identical to the Noname_XL-LOGIC16-100M.

  • FPGA: Markings ground off
  • USB interface chip: Cypress CY7C68013A
  • I²C EEPROM: Markings ground off
  • 3.3V voltage regulator: TD 6810 adjustable version + 150k/680k resistors pair
  • 1.5V voltage regulator: TD 6810 adjustable version + 160k/240k resistors pair
  • Crystal (FX2): 24MHz
  • Crystal (FPGA): Looks like 32MHz?
  • FPGA bitstream: 25P10 1MBit SPI NOR flash, ST Microelectronics
  • Bootstrap controller: Not required?

Hardware (2014-01-25 variant)

The PCB is marked "Saleae Logic 16 mcupro 2014.1.25".

  • FPGA: Markings ground off, but pinout and JTAG (IDCODE 0x020810dd) indicate an Altera Cyclone EP1C3T100.
  • USB interface chip: Markings sometimes ground off ? CY7C68013A
  • Crystal (FX2): marked "DKF 24.000"
  • Crystal (FPGA): marked "RAK32.00"
  • FPGA bitstream: 25P10 1MBit SPI NOR flash, ST Microelectronics (see Micron M25P10 too)
  • I²C EEPROM: None ? (CY7C I2C port wired to FPGA pins)
  • Bootstrap controller: Markings ground off, pinout could indicate a STCMCU 15F10x 8051-based mcu?
  • 3.3V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 150k/680k resistors pair
  • 1.5V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 160k/240k resistors pair
  • Channel input buffering: none, only simple resistor (510R) + TVS diode array protection (possibly Semtech SRV05)


The bottom two channels are not GND, but SCK (sample clock out) and HCK (half of SCK out).

Firmware

Actel variant
This logic analyzer works with unmodified Saleae software. The Actel FPGA has on-chip flash storage, so it only requires an upload of Cypress FX2LP firmware in order to operate.
Cyclone variant
This logic analyzer works with unmodified Saleae software. The PCB contains an SPI flash chip, so it only requires an upload of Cypress FX2LP firmware in order to operate.
2015-01-08 variant
Only requires an upload of Cypress FX2LP firmware to operate. Open-source binaries from gregani work, but must be renamed to saleae-logic16-fx2.fw. It also requires a libsigrok more recent than 2014-08-22 to work (see bug #680).
2014-01-25 variant
Seems to have the bitstream in internal flash, so it only requires an upload of Cypress FX2LP firmware in order to operate. This requires a libsigrok more recent than 2014-08-22 to work (see bug #680).

The firmware extraction steps are identical to steps for Saleae Logic16, however you only need to have saleae-logic16-fx2.fw installed.
