AMD XC2V80-6CSG144C

Overview

XC2V80-6CSG144C from Xilinx is a Virtex-II platform FPGA with 80K system gates, 512 Configurable Logic Blocks (CLBs), 16 dedicated 18×18 multipliers, and 144 user I/O pins in a 144-ball chip-scale BGA (CSG144) package. It features dual-port 18-Kb Block SelectRAM, Digitally Controlled Impedance (DCI) I/O, and four Digital Clock Managers (DCMs) for precise clock de-skew and phase shifting - deployed in high-speed telecom and DSP interface designs.

For engineers reviewing the XC2V80-6CSG144C datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.5 V core supply, support for LVDS/PCI/LVCMOS I/O standards, DCM-based clock synthesis up to 420 MHz internal operation, and compatibility with Xilinx Foundation and Alliance development tools for VHDL/Verilog synthesis of medium-complexity logic systems.

Technical Context

The XC2V80-6CSG144C implements a SRAM-based, reprogrammable architecture built on a 0.15 µm / 0.12 µm 8-layer metal CMOS process. Its logic fabric comprises 512 CLBs (each with four slices), 16 multiplier blocks, and four 18-Kb Block SelectRAM modules - all interconnected via Active Interconnect Technology routing with predictable delay independent of fanout.

Each IOB supports single-ended (LVTTL, LVCMOS, PCI, SSTL, HSTL) and differential (LVDS, BLVDS, LVPECL) signaling, with programmable drive strength (2–24 mA) and on-chip DCI termination. Four DCMs provide fully digital clock management including frequency synthesis (M/D ratio), ±180° coarse phase shift, and 1/256-cycle fine-grained adjustment - enabling synchronous DDR I/O and low-jitter system timing.

Key Specifications

Pinout & Package

XC2V80-6CSG144C uses a 144-ball chip-scale BGA (CSG144) package with 0.80 mm pitch and 12×12 mm body size. The package supports wire-bond interconnect and is RoHS-compliant (Pb-free). Pin definitions follow Xilinx's standard Virtex-II ball-out mapping for CSG144, including dedicated configuration (PROG_B, INIT_B, CCLK, DONE), JTAG (TCK/TMS/TDI/TDO), and dual-purpose I/O banks with bank-specific VCCO and VREF assignments.

FAQ

What is the maximum operating frequency of the XC2V80-6CSG144C internal logic?

The XC2V80-6CSG144C supports up to 420 MHz internal clock speed per Advance Data specifications in DS031. This performance is achievable under optimal placement and routing conditions using the -6 speed grade, which guarantees timing closure for critical paths including CLB-to-CLB and register-to-register logic. Actual system frequency depends on design complexity, resource utilization, and clock domain structure - verified during static timing analysis in Xilinx ISE.

Does the XC2V80-6CSG144C support LVDS I/O at 840 Mb/s?

Yes, the XC2V80-6CSG144C supports LVDS I/O at up to 840 Mb/s as specified in DS031 Module 1. This capability relies on dedicated current-mode LVDS drivers, matched termination via DCI, and DDR-capable IOB registers. Achieving 840 Mb/s requires proper PCB layout (controlled impedance, length matching), correct VCCO = 2.5 V or 3.3 V assignment per bank, and DCM-synchronized sampling clocks - validated using Xilinx's IBIS models and timing constraints.

How many Block SelectRAM modules does the XC2V80-6CSG144C contain?

The XC2V80-6CSG144C contains four 18-Kb Block SelectRAM modules, as confirmed in Table 1 of DS031-1. Each module operates as dual-port RAM with independent read/write ports, configurable depth/width (e.g., 16K×1 to 512×36), and three read-during-write modes. These blocks are physically distributed across the die and connect to four switch matrices - enabling concurrent access for data buffering, coefficient storage, or FIFO implementation within XC2V80-6CSG144C designs.

Is the XC2V80-6CSG144C pin-compatible with other Virtex-II devices in the CSG144 package?

Yes, all Virtex-II devices offered in the CSG144 package - including XC2V40, XC2V80, and XC2V250 - share identical pinouts and footprint. This allows hardware reuse across density points, provided I/O banking constraints and VCCO/VREF assignments are maintained. However, unused pins on lower-density variants remain unconnected; XC2V80-6CSG144C utilizes all 144 balls for I/O, configuration, and power, with no reserved or NC pins beyond the 15 mandatory control signals defined in DS031.

What configuration modes does the XC2V80-6CSG144C support?

The XC2V80-6CSG144C supports five configuration modes: Slave-Serial, Master-Serial, Slave SelectMAP, Master SelectMAP, and Boundary-Scan (IEEE 1532). Configuration is initiated via PROG_B, clocked by CCLK, and verified by DONE assertion. Bitstream encryption using Triple-DES is optional. All modes use SRAM-based in-system reprogrammability - enabling field updates, partial reconfiguration, and readback of configuration memory and flip-flop states for debug, all supported natively in XC2V80-6CSG144C.
