AMD XC4044XL-3BG432C

Overview

XC4044XL-3BG432C from Xilinx is a Field-Programmable Gate Array (FPGA) with 44,000 usable gates, 432-pin Ball Grid Array (BGA) package, -3 speed grade, and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control, protocol bridging, and real-time signal preprocessing applications.

For engineers reviewing the XC4044XL-3BG432C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (312 user I/Os), configuration mode (serial PROM or parallel slave), internal RAM capacity (288 bits), and TCK/TMS/TDI/TDO JTAG boundary-scan compliance.

Technical Context

The XC4044XL-3BG432C belongs to the Xilinx XC4000XL FPGA family, built on 0.5 µm CMOS technology with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports in-system programming via JTAG IEEE 1149.1 and uses SRAM-based configuration memory.

Configuration is volatile and requires external PROM or processor loading at power-up. The device includes dedicated carry logic for high-speed arithmetic and global clock routing with low skew.

Key Specifications

Pinout & Package

XC4044XL-3BG432C is housed in a 432-ball plastic BGA package (package code BG432) with 312 user I/Os, 8 dedicated configuration pins (e.g., INIT, PROGRAM, CCLK, DIN), 4 JTAG boundary-scan pins (TCK, TMS, TDI, TDO), and power/ground balls distributed across the array.

Manufacturer

Xilinx, now part of AMD, pioneered programmable logic devices and developed the XC4000 family as one of the first widely adopted SRAM-based FPGA platforms.

The XC4000XL product line was designed for cost-sensitive, high-reliability embedded systems requiring reconfigurable logic with predictable timing and JTAG testability.

FAQ

What is the maximum operating frequency of the XC4044XL-3BG432C?

The XC4044XL-3BG432C has a -3 speed grade specifying a maximum CLB-to-CLB clock frequency of 125 MHz under commercial temperature and voltage conditions. This value is verified per Xilinx's published timing models and applies to synchronous paths within the FPGA fabric. Actual system frequency depends on design topology, placement, and routing. The XC4044XL-3BG432C does not guarantee higher frequencies without derating or characterization.

Does the XC4044XL-3BG432C support in-system programming?

Yes, the XC4044XL-3BG432C supports in-system programming via its IEEE 1149.1-compliant JTAG port (TCK/TMS/TDI/TDO pins). Configuration bitstreams can be loaded dynamically during operation or at power-up using an external controller. The XC4044XL-3BG432C retains no configuration state after power loss and requires reprogramming each time.

How many user I/O pins does the XC4044XL-3BG432C provide?

The XC4044XL-3BG432C provides 312 user-configurable I/O pins in its 432-ball BGA package. These support TTL, LVTTL, and CMOS signaling standards with programmable drive strength and slew rate. Power and ground balls, configuration pins, and JTAG pins are separate from this count. The XC4044XL-3BG432C's I/O count enables complex multi-interface designs without external glue logic.

What configuration methods are supported by the XC4044XL-3BG432C?

The XC4044XL-3BG432C supports master serial, slave serial, and slave parallel configuration modes. Master serial uses an external PROM and the CCLK/DIN pins; slave modes rely on an external controller driving the configuration bus. JTAG is also supported for programming and boundary-scan testing. The XC4044XL-3BG432C does not support configuration from flash memory directly - external PROM or microcontroller intervention is required.

Is the XC4044XL-3BG432C still in production?

The XC4044XL-3BG432C is a mature device from the discontinued XC4000XL family. Xilinx ended mainstream production years ago, but Aetrix Electronics maintains traceable inventory and long-term supply support for legacy industrial and aerospace programs. The XC4044XL-3BG432C is not recommended for new designs unless continuity assurance is contractually guaranteed.
