AMD XC4036XLA-09BG432C

Overview

XC4036XLA-09BG432C from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) in the XC4000XLA family, featuring 3,078 logic cells, 22,000–65,000 typical gate range, 41,472 on-chip RAM bits, and 288 user I/Os in a 432-pin Ball Grid Array (BGA) package. It supports synchronous system clock rates up to 80 MHz, includes edge-triggered and dual-port SelectRAM™, and targets PCI-compliant embedded control and data-path acceleration.

For engineers reviewing the XC4036XLA-09BG432C 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, PCI compliance at -09 speed grade, and CLB-level latch capability - all critical for legacy re-engineering and high-reliability industrial FPGA deployments.

Technical Context

The XC4036XLA-09BG432C implements a regular array of 36×36 Configurable Logic Blocks (CLBs), each containing dual 4-input function generators (F/G), a 3-input H generator, two storage elements configurable as D flip-flops or latches (XC4000XLA-specific), and dedicated carry logic. Its routing architecture includes 22 additional vertical and 12 horizontal interconnect lines per CLB row/column versus XC4000E, plus early-clock buffers for IOB input capture.

This device uses a 0.35 µm SRAM process, operates at 3.3 V core voltage with 5 V-tolerant I/Os, and features eight global low-skew clock networks plus four additional address bits in Master Parallel configuration mode - enabling support for large daisy-chained PROMs and deterministic timing closure in synchronous systems up to 80 MHz.

Key Specifications

Pinout & Package

XC4036XLA-09BG432C is housed in a 432-ball plastic ball grid array (BG432) package with 35 mm × 35 mm body size and 1.27 mm ball pitch. The package supports standard surface-mount assembly and provides thermal and electrical performance suitable for industrial temperature operation (0°C to 70°C).

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA-based logic implementation applications.

Compared with XC4036XLA-09BG432C, the XC4036XL-09BG432C offers identical packaging and basic logic resources but omits latch-mode CLBs and advanced clocking - making it unsuitable for legacy ASIC emulation. The XCV300E-09BG432C delivers higher performance and memory but mandates full hardware and toolchain revision.

Availability

XC4036XLA-09BG432C is available at Aetrix Electronics and suitable for industrial motion control, legacy system emulation, PCI-based data acquisition, and high-reliability communications requiring stable component supply and long-term obsolescence management.

Supply support for XC4036XLA-09BG432C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGA technology and developed the XC4000 family as the industry's first high-density, SRAM-based programmable logic platform.

The XC4000XLA product line was designed specifically for 3.3 V industrial and telecom applications requiring PCI compliance, deterministic timing, and seamless migration from earlier XC4000E devices.

FAQ

What is the maximum system clock frequency supported by XC4036XLA-09BG432C?

The XC4036XLA-09BG432C supports synchronous system clock rates up to 80 MHz, as guaranteed by its -09 speed grade. This rating applies to fully constrained, place-and-routed designs meeting Xilinx timing requirements for setup/hold and clock skew. Internal logic paths can exceed 150 MHz in optimized configurations, but system-level operation is validated to 80 MHz for PCI-compliant interfaces and deterministic control loops.

Does XC4036XLA-09BG432C support dual-port RAM functionality?

Yes, XC4036XLA-09BG432C supports dual-port RAM at the CLB level: any CLB can be configured as a 16×1 dual-port RAM with independent read and write ports, enabling simultaneous access to the same or different addresses. This feature is implemented using the F and G function generators and is fully supported in Xilinx Foundation and Alliance software toolchains.

Is XC4036XLA-09BG432C pin-compatible with other XC4000X series devices?

XC4036XLA-09BG432C is pinout-compatible with XC4036EX/XL devices in the same BG432 package, including XC4036EX-09BG432C and XC4036XL-09BG432C. However, it is not bitstream-compatible with XC4000 or XC4000E families due to architectural enhancements including latch-mode CLBs and expanded routing resources.

What voltage levels does XC4036XLA-09BG432C support on its I/O pins?

XC4036XLA-09BG432C supports 5 V-tolerant I/Os operating at 3.3 V VCCO, allowing direct interfacing with legacy 5 V TTL and CMOS logic without level shifters. Input thresholds are fixed at 1.6 V for compatibility with both 3.3 V and 5 V signaling standards, and output drivers can be configured globally as TTL-like or CMOS-style.

Can XC4036XLA-09BG432C be reconfigured in-system?

Yes, XC4036XLA-09BG432C supports unlimited in-system reconfiguration via slave serial, slave parallel, or boundary-scan (JTAG) modes. Configuration data is loaded into internal SRAM cells, and the PROGRAM pin triggers asynchronous reload. Read-back capability allows verification of bitstream integrity and internal node observability for debug.
