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: 24.000MHz

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): 24.000MHz
• Crystal (FPGA): 100.000MHz
• FPGA Bitstream 25P10 1MBit SPI NOR flash, ST Microelectronics
• Bootstrap Controller STCMCU 15F10, 8051 compatible

Hardware (2015-01-08 variant)

PCB 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): 24.000MHz
• Crystal (FPGA): Looks like 32Mhz?
• FPGA Bitstream 25P10 1MBit SPI NOR flash, ST Microelectronics
• Bootstrap Controller Not required?

Hardware (2014-01-25 variant)

PCB Marked "Saleae Logic 16 mcupro 2014.1.25"

• FPGA: Markings ground off
• USB interface chip: Markings ground off
• MISC, bottom two channels are not GND, but SCK(Sample Clock out) and HCK (Half of SCK out).

This device may be bought from Aliexpress magazine for $33 + free shipping.

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 a serial flash chip, so it only requires an upload of Cypress FX2LP firmware in order to operate.

2015-1-8 variant

Only requires an upload of Cypress FX2LP firmware to operate. Opensource binaries from [1] work, but must be renamed to saleae-logic16-fx2.fw

2014-01-25 variant

Seems to have firmware into internal flash so doesn't require extraction from original Logic supplemental software to operate with Sigrok. You need to use fresh version of Sigrok umbrella, for example Debian packages at version 0.3.0 doesn't work with this clone (read discussion at bug#680).

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