AMD XC9572XL-10PC44I

Overview

XC9572XL-10PC44I from AMD (acquired by Xilinx) is a high-performance CPLD featuring 72 macrocells, 800 usable gates, 44-pin PLCC package, 10 ns maximum pin-to-pin delay, and in-system programmable via JTAG. It serves as a logic replacement for TTL/SSI/MSI in industrial control I/O expansion.

For engineers reviewing the XC9572XL-10PC44I datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay budget, macrocell count for state machine depth, PLCC thermal and mechanical compatibility, and JTAG-based field reprogrammability for maintenance.

Technical Context

The XC9572XL-10PC44I implements a multi-level PAL-style architecture with four function blocks, each containing 18 macrocells with configurable product-term sharing and buried register feedback. Its global clock, three global output enables, and two global set/reset signals support synchronous logic design across all blocks.

It operates over industrial temperature range (–40°C to +85°C), supports 3.3 V ±10% supply, and features slew-rate controlled outputs to reduce EMI. Configuration is retained without external memory due to on-chip EEPROM cells programmed via IEEE 1149.1 JTAG interface.

FAQ

What is the maximum operating frequency supported by the XC9572XL-10PC44I?

The XC9572XL-10PC44I guarantees 10 ns maximum pin-to-pin propagation delay, enabling reliable operation at system clock frequencies up to 100 MHz. Actual achievable frequency depends on logic depth and routing; internal register-to-register paths may support higher rates in constrained designs. The XC9572XL-10PC44I does not specify a hard maximum clock frequency but provides timing parameters sufficient for synchronous logic in industrial control loops.

Does the XC9572XL-10PC44I require an external configuration memory?

No, the XC9572XL-10PC44I contains on-chip EEPROM that retains its configuration after power loss. This eliminates the need for external PROM or flash memory, simplifying board design and reducing bill-of-materials cost. The XC9572XL-10PC44I loads its logic definition automatically at power-up without host processor intervention.

Can the XC9572XL-10PC44I be reprogrammed in the field without removing it from the PCB?

Yes, the XC9572XL-10PC44I supports in-system programming (ISP) via its IEEE 1149.1 JTAG interface (pins 37–40). Field updates can be performed using standard JTAG adapters and Xilinx IMPACT or iMPACT software. The XC9572XL-10PC44I does not require UV erasure or socket extraction, enabling logic revisions during equipment maintenance.

What is the I/O voltage tolerance of the XC9572XL-10PC44I?

The XC9572XL-10PC44I operates with a nominal VCCIO of 3.3 V ±10%, and its I/O buffers are designed for 3.3 V LVTTL/LVCMOS levels. Input thresholds are compatible with 5 V-tolerant signaling only when external series resistors limit current; the XC9572XL-10PC44I itself is not 5 V tolerant and requires level translation for interfacing with 5 V systems.

Is the XC9572XL-10PC44I suitable for automotive applications?

The XC9572XL-10PC44I is rated for industrial temperature range (–40°C to +85°C) and is not qualified to AEC-Q100 standards. While it may function in some under-hood or infotainment environments, it lacks automotive-grade qualification, extended temperature screening, and failure-in-time (FIT) data. For automotive use, the XC9572XL-10PC44I should be evaluated case-by-case against specific OEM requirements and derating guidelines.
