FAQ
What is the maximum transceiver line rate supported by XC7K420T-1FFG1156I?
The XC7K420T-1FFG1156I supports a maximum transceiver line rate of 12.5 Gb/s using its GTPE2 transceivers. This enables compliance with PCIe Gen3 (8 GT/s encoded), SATA III (6 Gb/s), and SRIO Gen2 (5 Gb/s) standards. Each transceiver bank can operate independently at this rate with built-in clock data recovery and elastic buffers.
Does XC7K420T-1FFG1156I support partial reconfiguration?
Yes, XC7K420T-1FFG1156I supports partial reconfiguration through Vivado Design Suite. This allows runtime modification of specific logic regions without resetting the entire device or interrupting active functions. The feature relies on dedicated configuration logic and frame-based bitstream addressing validated for industrial temperature operation.
What configuration modes are available for XC7K420T-1FFG1156I?
XC7K420T-1FFG1156I supports Master SPI (x1/x2/x4), Slave SelectMAP (x8/x16), JTAG, and BPI parallel modes. Configuration is initiated via PROGRAM_B and controlled by M0–M2 pins. SPI mode is most common for compact designs due to minimal pin count and fast boot time from serial flash.
Is XC7K420T-1FFG1156I qualified for industrial temperature operation?
Yes, the "I" suffix in XC7K420T-1FFG1156I denotes industrial temperature grade (–40°C to +100°C junction). It is qualified per AEC-Q100 Class 3 standards for reliability and undergoes burn-in and HTOL testing. Thermal design must maintain junction temperature within this range using appropriate heatsinking and airflow.
What PCIe versions does the hard IP in XC7K420T-1FFG1156I support?
The XC7K420T-1FFG1156I integrates PCIe Gen3 Endpoint hard IP compliant with PCI Express Base Specification v3.0. It supports x1, x2, x4, and x8 lane widths with AXI4 streaming interface, TLP parsing/generation, and MSI/MSI-X interrupt handling-all implemented in dedicated silicon without consuming logic resources.
