Product details
Overview
XC4085XLA-09BG352I from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) featuring 7,448 logic cells, 100,352 RAM bits, and 448 user I/Os in a 352-pin BGA package. It implements synchronous edge-triggered and dual-port RAM per CLB, supports PCI-compliant operation at up to 80 MHz system clock rate, and delivers internal performance exceeding 150 MHz for embedded control and interface logic applications.
For engineers reviewing the XC4085XLA-09BG352I datasheet, pinout, applications, or equivalent options, key selection criteria include its 0.35 µm SRAM process, 3.3 V core voltage with 5 V-tolerant I/Os, CLB-level latch capability (XC4000X-only), and Master Parallel configuration support with 22-bit addressing for large-system integration.
Technical Context
The XC4085XLA-09BG352I belongs to the XC4000XLA family - a low-voltage, high-performance variant of the XC4000X series built on 0.35 µm SRAM technology. It features configurable CLBs with three function generators (F/G/H), dual-edge-triggered D-type flip-flops or latches per CLB, and dedicated carry logic enabling arithmetic throughput beyond 150 MHz.
Its IOBs support individually programmable slew rate, 5 V-tolerant inputs, and a fast capture latch driven by early global clocks - allowing input data synchronization with minimal delay before transfer to main flip-flops. The device uses eight global low-skew clock networks and includes IEEE 1149.1 boundary scan logic for testability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4085XL-08BG352C | Same logic capacity and package, but -08 speed grade (80 MHz vs. 90 MHz max internal), commercial temperature range (0°C to 70°C) | Not rated for extended industrial temperature operation; lacks extended life cycle support | Select when cost sensitivity outweighs need for margin in timing-critical paths or extended temp operation |
| XCV1000E-8BG560C | Virtex-E family successor with 1M system gates, 180+ MHz performance, and enhanced SelectRAM+, but incompatible pinout and architecture | Requires full HDL redesign and PCB layout change; supports advanced features like DLLs and block RAM | Choose for new designs needing higher density, faster clocks, or migration path beyond XC4000X lifecycle limits |
Compared with XC4085XLA-09BG352I, the XC4085XL-08BG352C offers identical footprint and logic resources at lower speed grade and commercial temp rating, while the XCV1000E-8BG560C provides architectural evolution with greater capacity and speed but mandates full hardware and software requalification.

FAQ
What is the operating temperature range for XC4085XLA-09BG352I?
The XC4085XLA-09BG352I is specified for industrial temperature operation from –40°C to +85°C. This extended range ensures reliable functionality in harsh environments such as base station equipment, factory automation controllers, and outdoor telecom cabinets where thermal cycling and ambient extremes are common. The device maintains timing compliance across this full range under 3.3 V core supply.
Does XC4085XLA-09BG352I support boundary scan testing?
Yes, XC4085XLA-09BG352I includes IEEE 1149.1-compliant boundary scan logic integrated into its configuration architecture. This allows full pin-level visibility and controllability during board-level test, supporting JTAG-based programming, interconnect verification, and in-system diagnostics without requiring additional test fixtures or probes.
Can XC4085XLA-09BG352I be used as a drop-in replacement for XC4085XL-09BG352I?
No - XC4085XLA-09BG352I and XC4085XL-09BG352I are not pin-compatible or bitstream-compatible. While both use the same 352-pin BG352 package and share logic resources, the XLA variant includes enhanced low-voltage features and different configuration behavior. Migration requires full re-synthesis and place-and-route with Xilinx Foundation or Alliance software targeting the XLA family.
What configuration modes does XC4085XLA-09BG352I support?
XC4085XLA-09BG352I supports Master Serial, Slave Serial, Master Parallel, and Slave Parallel configuration modes. In Master Parallel mode, it uses 22-bit addressing - an extension over XC4000E's 18-bit limit - enabling seamless daisy-chaining of multiple large FPGAs from a single PROM without external address decoding logic.
Is XC4085XLA-09BG352I still in active production?
No - XC4085XLA-09BG352I is obsolete and no longer in active production by AMD/Xilinx. However, Aetrix Electronics maintains verified legacy inventory with full traceability and extended lifecycle support documentation, enabling continued manufacturing for long-lifecycle industrial, defense, and medical programs dependent on this specific speed-grade and temperature-rated variant.
