MPN: XC7K325T-1FFG676C ✓ AktifXC7K325T-1FFG676C Ringkasan
A Field Programmable Gate Array (FPGA) is an integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic functions. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), which are a subset of application-specific integrated circuits (ASICs) but offer reconfigurability. The Kintex-7 family is positioned as the best price/performance/watt balance in the 7-series, bridging the gap between the low-cost Artix-7 and the high-end Virtex-7.
Key features include 840 DSP48E1 slices for high-throughput signal processing, 500 MHz maximum clock frequency, and support for DDR3 memory interfaces. The device integrates 10.3 Gbps transceivers (GTX) for high-speed serial communication, and includes hardened blocks for PCIe Gen3 and 10G Ethernet MAC. The -1 speed grade provides a balanced performance point, while the C temperature grade supports commercial operation from 0°C to 85°C.
Architecturally, the Kintex-7 uses a 6-input look-up table (LUT) fabric with 203,800 LUTs, organized into configurable logic blocks (CLBs). The device includes 10 clock management tiles (CMTs) with mixed-mode clock managers (MMCMs) and phase-locked loops (PLLs) for flexible clock generation. The 28nm high-k metal gate (HKMG) process technology delivers up to 50% lower power than previous generations while maintaining high logic density.
Typical applications include software-defined radio, high-performance computing acceleration, video and image processing, and wired communications infrastructure. The 400 I/Os support a wide range of I/O standards including LVCMOS, LVDS, and HSTL, making it versatile for board-level integration.
When designing with this device, careful attention to power supply decoupling is essential. The core voltage must be regulated to 1.0V with adequate bypass capacitance, and the configuration bitstream must be loaded from an external SPI flash or via JTAG. Thermal management is critical at high utilization; a heatsink or forced airflow is recommended for sustained operation above 50% logic utilization.

Catatan Desain
The XC7K325T-1FFG676C requires a 1.0V core supply (VCCINT) with tight regulation (0.97V to 1.03V). Use a dedicated switching regulator with at least 10A capability and place 100nF and 10uF ceramic capacitors close to each VCCINT pin. The VCCAUX rail (1.8V) and VCCBRAM (1.0V) also need proper decoupling. Refer to AMD's UG583 for detailed power supply design guidelines.
At 50% logic utilization and 400 MHz, the XC7K325T-1FFG676C can dissipate 5-10W. The FCBGA package has a thermal resistance of approximately 8-10°C/W (theta_JA) without airflow. For sustained operation, attach a heatsink or provide forced airflow to keep junction temperature below 85°C. Use AMD's Power Estimator to calculate exact dissipation for your design.
The 676-pin FCBGA requires a multi-layer PCB with at least 8 layers for proper routing and power integrity. Use 0.8mm via diameter and 0.4mm drill for signal vias. Route high-speed transceiver pairs with controlled impedance (100 ohm differential) and keep them away from clock signals. Follow AMD's PCB design guidelines in UG583 for layout best practices.
