AMD XC9572XL-7VQ44I

Overview

XC9572XL-7VQ44I from AMD is a high-performance CPLD featuring 72 macrocells, 1.6 ns pin-to-pin propagation delay, and 5 V tolerant I/Os in a 44-pin VQFP package. It implements complex combinational and sequential logic for system control, glue logic replacement, and interface bridging in industrial PLCs and legacy bus adapters.

For engineers reviewing the XC9572XL-7VQ44I datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay, macrocell count, I/O voltage tolerance, JTAG boundary-scan support, and VQFP thermal performance under sustained logic activity.

Technical Context

This device belongs to the XC9500XL family of in-system programmable CPLDs built on 0.35 µm CMOS technology. It integrates three function blocks with dedicated product-term sharing, global clock and output enable controls, and programmable slew-rate limiting per I/O pin.

The architecture supports up to 180 product terms per macrocell, asynchronous reset and preset, and configurable pin assignments via Xilinx WebPACK or ISE design tools. All logic is non-volatile using EEPROM-based configuration memory.

FAQ

What is the maximum operating frequency supported by XC9572XL-7VQ44I?

The XC9572XL-7VQ44I supports a maximum system frequency of 125 MHz under typical conditions, based on its 7 ns pin-to-pin propagation delay and internal timing characteristics. This allows reliable operation in control loops and data path logic up to that rate. The actual achievable frequency depends on design complexity, routing, and loading. XC9572XL-7VQ44I does not include an internal PLL, so clock distribution relies on external sources or global clock pins.

Does XC9572XL-7VQ44I require external configuration memory?

No, XC9572XL-7VQ44I contains on-chip EEPROM configuration memory and powers up fully operational without external PROM or flash. Configuration is retained indefinitely without power. XC9572XL-7VQ44I supports in-system programming via JTAG, eliminating the need for socketed EPROM programmers or configuration controllers in the final system.

Can XC9572XL-7VQ44I interface directly with 5 V TTL devices?

Yes, XC9572XL-7VQ44I features 5 V-tolerant I/O pins compatible with TTL voltage levels, enabling direct connection to 5 V logic without level shifters. Input thresholds meet TTL specifications, and output drive strength supports standard fan-out. XC9572XL-7VQ44I maintains this compatibility while operating from a 3.3 V core supply.

Is JTAG boundary-scan supported on XC9572XL-7VQ44I?

Yes, XC9572XL-7VQ44I implements full IEEE 1149.1 JTAG boundary-scan functionality including EXTEST, SAMPLE/PRELOAD, and BYPASS instructions. This enables in-circuit testing, interconnect verification, and in-system programming. XC9572XL-7VQ44I uses dedicated TCK, TMS, TDI, and TDO pins mapped to VQFP package pins 12, 13, 14, and 15 respectively.

What development tools are compatible with XC9572XL-7VQ44I?

XC9572XL-7VQ44I is supported by Xilinx WebPACK ISE 14.7 and earlier versions, including schematic capture, ABEL/HDL synthesis, and place-and-route. Programming files are generated in JEDEC format. XC9572XL-7VQ44I is not supported in Vivado; users must continue using the ISE toolchain for full functional verification and bitstream generation.
