AMD XC9572XL-10TQG100I

Overview

XC9572XL-10TQG100I from AMD (acquired Xilinx CPLD business) is a 72-macrocell in-system programmable CPLD with 10 ns propagation delay, 100-pin TQFP package, and 5 V tolerant I/Os. It serves as a glue logic replacement in legacy industrial control and telecom interface boards requiring deterministic timing and non-volatile configuration.

For engineers reviewing the XC9572XL-10TQG100I datasheet, pinout, applications, or equivalent options, key selection factors include macrocell count, pin-compatible migration path from XC9536/XC9552, I/O voltage tolerance, and JTAG boundary-scan support for board-level testability.

Technical Context

This device belongs to the XC9500XL family of high-performance, low-power CPLDs built on 0.35 µm CMOS technology. It implements three function blocks interconnected via a global routing pool, each supporting up to 24 macrocells with product-term-based logic and registered outputs.

Configuration is stored in on-chip EEPROM, enabling instant-on operation without external configuration memory. The device supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming via the JTAG port at 5 V.

Key Specifications

Pinout & Package

Manufacturer

AMD acquired Xilinx in 2022 and now owns the XC9500XL CPLD product line. Xilinx originally developed these devices for high-reliability, non-volatile programmable logic in industrial and telecom infrastructure.

The XC9500XL family was designed specifically for pin-compatible migration from bipolar PAL/GAL devices and to replace discrete TTL logic in 5 V systems requiring zero-configuration startup and field-upgradable logic.

FAQ

What is the maximum clock frequency supported by XC9572XL-10TQG100I?

The XC9572XL-10TQG100I supports a maximum system clock frequency of 100 MHz, derived from its 10 ns propagation delay (tPD) and internal register-to-register timing path. This allows reliable operation in synchronous control loops such as motor encoder sampling or serial protocol state machines. The actual achievable frequency depends on logic depth and routing congestion, but the 10 ns spec guarantees timing closure for designs meeting Xilinx's recommended floorplanning guidelines for the XC9500XL architecture.

Does XC9572XL-10TQG100I require an external configuration PROM?

No, XC9572XL-10TQG100I does not require an external configuration PROM. Its on-chip EEPROM stores the configuration bitstream permanently, enabling instant-on operation after power-up. This eliminates boot-time delays and external memory components, making XC9572XL-10TQG100I ideal for safety-critical and maintenance-sensitive applications like medical diagnostics equipment and railway signaling interfaces.

Can XC9572XL-10TQG100I operate with 3.3 V I/O signals?

XC9572XL-10TQG100I supports 3.3 V logic levels on its I/O pins only when driven by 3.3 V sources, but it requires a 5 V VCC supply and maintains 5 V-tolerant inputs. It cannot drive 3.3 V–rated loads directly without series resistors or level translators. For mixed-voltage systems, XC9572XL-10TQG100I is typically used with 5 V–compatible peripherals; true 3.3 V–native operation requires the XCR3000 series instead.

Is XC9572XL-10TQG100I still in production or subject to obsolescence?

XC9572XL-10TQG100I is currently available through AMD's authorized distribution network under lifetime buy and last-time-manufacture programs. While no new wafer starts are planned, Aetrix Electronics maintains strategic inventory and offers extended lifecycle support-including counterfeit-free traceable lots and engineering support-for ongoing production of legacy systems relying on XC9572XL-10TQG100I.

How is JTAG used for programming XC9572XL-10TQG100I in-system?

JTAG programming of XC9572XL-10TQG100I uses the IEEE 1149.1 interface with TCK, TMS, TDI, and TDO pins. Configuration is performed via Xilinx IMPACT or third-party boundary-scan tools using SVF or XSVF files. The process writes directly to on-chip EEPROM without requiring device power cycling, enabling field updates of logic functions in deployed XC9572XL-10TQG100I units such as base station control cards.
