Lattice Programming Cable: What are the key differences of the HW-USBN-2B and HW-USBN-2A Programming Cable?

HW-USBN-2B supports all modes/features as the existing HW-USBN-2A except for 5V Programming signals. The SW programmer is backward compatible with previous supported device on previous SW versions.

FAQ

Programmer: Is HW-USBN-2B compatible with the MACH4A5 (M4A5) family?

The MACH4A5 is a 5V core device and cannot be programmed with an HW-USBN-2B cable. The HW-USBN-2B supports the programming of Lattice devices with a core voltage of up to 3.3V. Programming devices with a 5V core requires the HW-USBN-2A USB cable or HW-DLN-3C parallel cable. These 5V…

FAQ

Programmer: Why does programming fails with error flag in status register when using the HW-USBN-2B programmer in SSPI NVCM mode?

Solution:One bit asserted and flag as 1. FEA OTP has been asserted which means that feature row is set to be one-time programmable. The expected value should be unasserted which is 0; however, it got an error because this bit (error 15) asserted to 1.You may check with FPGA-TN-02039 (page 9) that…

FAQ

Where should I connect the VCC pin of the HW-USBN-2B cable if I'm programming an iCE40 device?

The VCC pin of the HW-USBN-2B programmer is an input probe. It detects what voltage is being used by your design. You may connect the VCC probe to the voltage used by Bank1 of your design (which is associated with SPI_SI, SPI_SO, SPI_SCK and SPI_SS pins.

FAQ

What is the max current that can be sourced from the 5V Out pin on the HW-USBN-2B programming cable?

The "5V Out" pin is directly connected to the USB's 5V supply. You can determine the maximum current by checking the USB port specifications. This is typically around 500mA on USB 2.0 ports. It could be higher or lower depending on the manufacturer.

FAQ

What will be the resulting programming speed when selecting various "TCK Divider Setting (0-30x)" values between 0-30 in the Diamond Programmer, used along with HW-USBN-2B cable?

The "TCK Divider Setting (0-30x)" allows you to slow down the TCK clock, thereby reducing the Programming speed.This is done by extending the low period of the clock.Refer the following table for specific frequency settings for the HW-USBN-2B programming cable: Divider Programming Frequency…

FAQ

Crosslink: How to program the CrossLink through I2C with Lattice Diamond Programmer and Lattice HW-USBN-2B download cable or MCU-based I2C programming using I2CEMBEDDED?

The CrossLink device is programmable using SPI or I2C. Thus, the programming is supported through:1.  SPI/I2C-based embedded programming (SSPIEMBEDDED or I2CEMBEDDED) using an Embedded MCU, or2.  SPI/I2C operations through Lattice Diamond Programmer using a HW-USBN-2B cable.These procedures…
