AMD XC4044XL-2BG352I

Overview

XC4044XL-2BG352I from Xilinx is a Field-Programmable Gate Array (FPGA) featuring 44,000 usable gates, 352-pin Ball Grid Array (BGA) packaging, -2 speed grade, and industrial temperature range (-40°C to +100°C). It implements synchronous logic designs with embedded SRAM blocks and configurable I/Os for digital signal processing and control applications.

For engineers reviewing the XC4044XL-2BG352I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (284 user I/Os), speed grade timing performance, BGA thermal and routing constraints, and legacy 5V-tolerant I/O compatibility.

Technical Context

The XC4044XL-2BG352I belongs to the Xilinx XC4000XL family, built on a 0.5 µm CMOS process with 4-input LUT-based logic cells. It supports in-system configuration via JTAG boundary-scan and includes dedicated carry logic for high-speed arithmetic.

It integrates up to 284 user-configurable I/O pins with programmable slew rate and drive strength, and supports multiple I/O standards including LVTTL, LVCMOS, and 5V-tolerant inputs. Configuration memory is SRAM-based and requires external PROM or processor loading.

FAQ

What is the maximum operating frequency of the XC4044XL-2BG352I?

The XC4044XL-2BG352I has a -2 speed grade, guaranteeing a maximum clock frequency of 125 MHz for CLB-to-CLB paths under industrial temperature conditions. This value is measured using standard Xilinx timing analysis tools and reflects worst-case performance across voltage and temperature corners. Actual system-level timing depends on design routing, I/O standards, and clock network usage. The XC4044XL-2BG352I datasheet provides detailed timing parameters for setup/hold, propagation delay, and carry chain performance.

Does the XC4044XL-2BG352I support in-system programming?

Yes, the XC4044XL-2BG352I supports in-system programming via its IEEE 1149.1-compliant JTAG interface. Configuration bitstreams can be loaded through TDI/TDO pins without removing the device from the PCB. The XC4044XL-2BG352I also supports master serial and slave parallel modes using external PROM or microcontroller. JTAG boundary-scan functionality enables both programming and interconnect testing.

Is the XC4044XL-2BG352I 5V-tolerant on all I/O pins?

Yes, all 284 user I/O pins of the XC4044XL-2BG352I are 5V-tolerant, allowing direct connection to 5V TTL and CMOS logic without external level shifters. This tolerance applies regardless of VCCO setting (3.3V or 5V), and is verified per Xilinx specification DS031. The XC4044XL-2BG352I maintains this capability across its full industrial temperature range.

What package type does the XC4044XL-2BG352I use?

The XC4044XL-2BG352I uses a 352-ball plastic ball grid array (PBGA) package with 1.27 mm ball pitch and 35 mm × 35 mm body size. This BG352 package is standardized across the XC4000XL family and supports automated assembly, thermal vias, and high-density routing. The XC4044XL-2BG352I pinout and mechanical drawings are documented in Xilinx package drawing 02-0001.

Can the XC4044XL-2BG352I be used in automotive applications?

The XC4044XL-2BG352I is rated for industrial temperature range (–40°C to +100°C) but is not AEC-Q100 qualified. While it may function in some under-hood or infotainment environments, Xilinx does not certify the XC4044XL-2BG352I for automotive safety-critical systems. For automotive use, designers should select AEC-Q100-qualified FPGAs such as the Xilinx Automotive (XA) series. The XC4044XL-2BG352I remains appropriate for industrial and test equipment where qualification is not mandated.
