The KingST KQS3506-LA16100 is a USB-based, 16-channel logic analyzer with 100/50/25/12.5MHz sampling rate (at 2/4/8/16 enabled channels).
This is a clone of the Saleae Logic16.
See KingST KQS3506-LA16100/Info for more details (such as lsusb -vvv output) about the device.
Hardware
- FPGA: Xilinx Spartan-3A XC3S200A, 200K gates (datasheeet)
- CPLD: Altera EPM3032A, 600 gates, 32 macrocells (datasheet, pinout).
- USB interface chip: Cypress CY7C68013A-56PVXC (FX2LP) (datasheet)
- I2C EEPROM: Microchip 24LC02B (datasheet)
- 3.3V voltage regulator: Advanced Monolithic Systems AMS1117-3.3 (datasheet, older datasheet)
- 1.2V voltage regulator: Advanced Monolithic Systems AMS1117-1.2 (datasheet, older datasheet)
Pinouts and connections:
I2C EEPROM:
The Microchip 24LC02B is connected to the Cypress FX2. The WP pin of the EEPROM can be jumpered to low or high, in order to write-protect it (or not). The address pins (A0-A2) are all connected to GND, which makes the I2C EEPROM address of the EEPROM 0x50.
| A0 (GND) | 1- | O | -8 | VCC (3.3V) |
| A1 (GND) | 2- | -7 | WP (jumper) | |
| A2 (GND) | 3- | -6 | SCL (FX2 SCL) | |
| GND | 4- | -5 | SDA (FX2 SDA) |
