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 (2018 variant)
The PCB is marked "Logic 16 Saleae". This variant also comes in a case identical to the Noname_XL-LOGIC16-100M.
- FPGA: Markings ground off, but pinout indicates an Altera Cyclone EP1C3T144.
- 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): 32MHz
- FPGA bitstream: ST M25P10VP, 1Mbit SPI NOR flash (datasheet)
- Bootstrap controller: Not required?
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: ST M25P10VP, 1Mbit SPI NOR flash (datasheet)
- Bootstrap controller: Not required?
Hardware (2014-01-25 variant)
The PCB is marked "Saleae Logic 16 mcupro 2014.1.25".
The bottom two channels are not GND, but SCK (sample clock out) and HCK (half of SCK out).
- FPGA: Markings ground off, but pinout and JTAG (IDCODE 0x020810dd) indicate an Altera Cyclone EP1C3T100.
- USB interface chip: Markings sometimes ground off? Cypress CY7C68013A
- Crystal (FX2): marked "DKF 24.000"
- Crystal (FPGA): marked "RAK32.00"
- FPGA bitstream: ST M25P10VP, 1Mbit SPI NOR flash (datasheet)
- I²C EEPROM: None? (CY7C68013A 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)

Protocol
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 and 2018 variants
- 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.
