AMD XC5VLX50-1FFV676C

Overview

XC5VLX50-1FFV676C from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 46,080 logic cells, 2.5 Gbps serial transceivers, and embedded Block RAM totaling 2,002 kbits. It implements high-speed signal processing in radar baseband subsystems with deterministic latency and multi-gigabit I/O.

For engineers reviewing the XC5VLX50-1FFV676C datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver compliance (GTP), I/O bank voltage support (1.2–3.3 V), and configuration interface type (Master SelectMAP).

Technical Context

The XC5VLX50-1FFV676C integrates 64 GTP transceivers operating up to 3.75 Gbps, supports DDR2/DDR3 memory interfaces with dedicated DQS logic, and uses 6-input LUTs with dual flip-flops per slice. Its clocking architecture includes 32 Digital Clock Managers (DCMs) and 16 Phase-Locked Loops (PLLs) for jitter reduction and frequency synthesis.

Configuration occurs via Master SelectMAP mode using parallel x16 or x32 bus, with JTAG boundary-scan support for IEEE 1149.1 testing. The device targets high-reliability applications requiring SEU mitigation through configuration scrubbing and built-in CRC checking.

FAQ

What is the maximum data rate supported by the GTP transceivers in XC5VLX50-1FFV676C?

The XC5VLX50-1FFV676C integrates 64 GTP transceivers rated for operation up to 3.75 Gbps. This supports protocols including PCIe Gen1 (2.5 Gbps), Serial RapidIO (3.125 Gbps), and Aurora (3.75 Gbps). Each transceiver includes built-in 8B/10B encoding, elastic buffers, and clock correction logic to maintain link integrity under varying jitter conditions. The XC5VLX50-1FFV676C datasheet specifies AC characteristics across temperature and voltage corners to ensure reliable operation at these rates.

Does XC5VLX50-1FFV676C support DDR3 memory interfaces?

XC5VLX50-1FFV676C supports DDR2 memory interfaces natively via dedicated DQS logic and I/O timing calibration. DDR3 support is not implemented in the Virtex-5 architecture; it requires external PHY or migration to Virtex-6 or later families. The XC5VLX50-1FFV676C I/O banks operate at VCCO voltages from 1.2 V to 3.3 V, compatible with DDR2 SDRAM signaling levels (1.8 V) but not DDR3's 1.5 V or 1.35 V requirements. Designers must verify timing closure using Xilinx ISE tools with the specific memory part.

What configuration modes are supported by XC5VLX50-1FFV676C?

XC5VLX50-1FFV676C supports Master SelectMAP (x8/x16/x32), Slave SelectMAP, JTAG, and Serial configuration modes. Master SelectMAP is the primary high-speed method, using parallel data loading from external flash memory. Mode selection is controlled by M2:M0 pins at power-up; M2:M0 = 000 configures x16 Master SelectMAP. JTAG is used for programming, debugging, and boundary-scan testing per IEEE 1149.1. The XC5VLX50-1FFV676C does not support passive serial or system ACE modes.

Is XC5VLX50-1FFV676C qualified for automotive applications?

XC5VLX50-1FFV676C is specified for commercial temperature range (0°C to +85°C) and is not AEC-Q100 qualified. It lacks automotive-specific screening, burn-in, or failure rate reporting required for automotive ECUs. While used in some non-safety-critical test equipment or aftermarket systems, the XC5VLX50-1FFV676C is not recommended for ADAS, powertrain, or chassis control applications. For such use cases, AMD recommends evaluating newer automotive-qualified FPGAs like the XA series.

How many Digital Clock Managers (DCMs) are available in XC5VLX50-1FFV676C?

XC5VLX50-1FFV676C contains 32 Digital Clock Managers (DCMs), each capable of input clock multiplication, division, phase shifting, and duty-cycle correction. These DCMs are distributed across the FPGA fabric and support independent clock domains for mixed-signal interfaces, memory controllers, and high-speed I/O. The XC5VLX50-1FFV676C does not integrate PLLs in place of DCMs; instead, it provides 16 additional PLLs for higher-frequency synthesis tasks, complementing the DCM set.
