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)
- FPGA: Actel A3P125
- USB interface chip: Cypress CY7C68013A
- I²C EEPROM: Atmel 24C02N
- 3.3V voltage regulator: Advanced Monolithic Systems AMS1117-3.3
- 1.5V voltage regulator: Advanced Monolithic Systems AMS1117-1.5
- Crystal: 24MHz
Hardware (Cylone variant)
- FPGA: Altera Cyclone EP1C3T100
- USB interface chip: Cypress CY7C68013A
- I²C EEPROM: Atmel 24C02N
- 3.3V voltage regulator: Advanced Monolithic Systems AMS1117-3.3
- 1.5V voltage regulator: Advanced Monolithic Systems AMS1117-1.5
- Crystal (FX2): 24MHz
- Crystal (FPGA): 100MHz
- FPGA bitstream: 25P10 1MBit SPI NOR flash, ST Microelectronics
- Bootstrap controller: STCMCU 15F10, 8051 compatible
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: Markings ground off, but presumably a Cypress FX2 like all others. Cypress CY7C68013A
- I²C EEPROM: Markings ground off
- 3.3V voltage regulator: Unrecognized switcher in SOT23-5 (Seems to be 3.8V?!)
- 1.5V voltage regulator: Unrecognised switcher in SOT23-5
- 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
- USB interface chip: Markings ground off
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.
- 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.
