Product details
Overview
XC4085XLA-09BG560I from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) featuring 7,448 logic cells, 55,000–180,000 typical gate range, and 100,352 on-chip RAM bits. It supports synchronous system clock rates up to 80 MHz, includes dual-port and edge-triggered RAM per CLB, and delivers PCI compliance for -2 and faster speed grades. It is used in high-density digital logic acceleration, protocol bridging, and embedded control subsystems.
For engineers reviewing the XC4085XLA-09BG560I datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count (3,136), I/O count (448), 0.35 µm SRAM process node, 3.3 V core voltage with 5 V-tolerant I/Os, and compatibility with Master Parallel and Slave Serial configuration modes.
Technical Context
The XC4085XLA-09BG560I belongs to the XC4000XLA family - a low-voltage, high-performance variant of the XC4000X series built on 0.35 µm SRAM technology. Its architecture comprises a 56 × 56 matrix of Configurable Logic Blocks (CLBs), each containing dual 4-input function generators (F/G), a 3-input H generator, two storage elements configurable as flip-flops (or latches in XC4000X), and dedicated carry logic.
It features eight global low-skew clock networks, programmable IOB slew rate, IEEE 1149.1 boundary scan, and flexible RAM configuration per CLB (16×2, 32×1, or 16×1 dual-port). Input threshold is fixed at 1.6 V, compatible with both 3.3 V CMOS and TTL levels, and outputs support 12 mA sink current.

FAQ
What is the operating temperature range for XC4085XLA-09BG560I?
The XC4085XLA-09BG560I is rated for industrial operation from –40°C to +100°C. This extended temperature range ensures reliable functionality in harsh environments such as motor drives, outdoor base stations, and avionics subsystems where thermal cycling and ambient extremes are common. The 'A' suffix in XC4085XLA explicitly denotes this industrial-grade qualification.
Does XC4085XLA-09BG560I support partial reconfiguration?
No, XC4085XLA-09BG560I does not support partial reconfiguration. It uses a monolithic configuration architecture where the entire bitstream must be reloaded to modify logic functionality. Partial reconfiguration was introduced in later Virtex families; the XC4000XLA series supports only full reconfiguration via Master Parallel, Slave Serial, or JTAG modes.
Is XC4085XLA-09BG560I pin-compatible with other XC4000X devices?
Yes, XC4085XLA-09BG560I is pin-compatible with other XC4000X family members in the BG560 package, including XC4085XL-09BG560C and XC4085XV-09BG560I. Pinout compatibility extends across speed grades and temperature variants, enabling drop-in replacement for functional upgrades or environmental qualification changes without PCB redesign.
What configuration modes does XC4085XLA-09BG560I support?
XC4085XLA-09BG560I supports Master Parallel, Slave Serial, Slave Parallel, and JTAG configuration modes. Master Parallel uses 22-bit addressing for fast PROM-based loading; Slave Serial enables daisy-chained programming via a single bitstream; JTAG provides in-system programming and boundary scan testing per IEEE 1149.1.
Can XC4085XLA-09BG560I interface directly with 5 V logic?
Yes, XC4085XLA-09BG560I features 5 V-tolerant I/Os, allowing direct connection to 5 V TTL or CMOS signals without external level-shifting circuitry. Its input threshold is fixed at 1.6 V, making it compatible with both 3.3 V and 5 V logic families - a key advantage for mixed-voltage system integration and legacy interface preservation.
