XC9572XL-5CS48C - 72-Macrocell CPLD 5ns 3.3V | AMD/Xilinx
料号： XC9572XL-5CS48C ✓ 量产中XC9572XL-5CS48C 概述
A Complex Programmable Logic Device (CPLD) is a class of programmable logic that sits between simple PAL/GAL devices and large FPGAs in the digital-logic hierarchy. CPLDs implement sum-of-products logic arrays with deterministic, pin-to-pin timing, making them ideal for glue logic, address decoding, bus interfacing, and power-on state machine control where predictable delays matter more than logic density.
Key features of the XC9572XL-5CS48C include 5 ns worst-case propagation delay, system frequencies up to 178.6 MHz, and the industry-standard XC9500XL architecture built on a 0.35 micron CMOS Flash process. Every macrocell is fully configurable, and the device supports in-system programming (ISP) with a minimum of 10,000 program/erase cycles per AMD product documentation. Flash retention is specified for 20 years, and individual macrocells provide product-term allocation, local feedback, and set/reset controls.
The FastFLASH technology combines a flash memory cell with the proven XC9500 switch matrix, giving designers low standby power - important for battery-backed and always-on 3.3V systems - while eliminating configuration PROMs required by SRAM-based FPGAs. The 48-ball chip-scale BGA footprint minimizes board area while offering the power integrity and signal integrity advantages of distributed power and ground balls.
Typical applications include address decoding and bus control in embedded processors, glue-logic consolidation replacing multiple 74-series devices, power-supply sequencing and reset management, industrial control I/O expansion, and communication-interface bridging. The commercial temperature rating (suffix C) suits office and laboratory environments.
Designers should observe AMD power-management guidelines: the device supports a standby mode with greatly reduced ICC, and unused I/O should be terminated as recommended in the datasheet (DS057). Because the package is a BGA, rework requires a reflow station, so verify footprint land patterns per AMD package drawings.
This page adds value beyond the datasheet by compiling drop-in same-family alternatives with speed-grade and temperature-suffix differences, distributor price evidence, practical design notes, and application guidance in one place.

典型应用
XC9572XL-5CS48C 适用于 6 应用s: Glue Logic Consolidation, Address Decoding and Bus Control, Power Sequencing and Reset Management, Industrial Control I/O Expansion, Communication Interface Bridging, Legacy Embedded Board Maintenance.
Glue Logic Consolidation
The XC9572XL-5CS48C excels at replacing multiple 74-series logic devices with a single programmable part. Its deterministic 5 ns pin-to-pin delay means decoded control signals behave exactly as designed with fixed, routing-independent timing - unlike SRAM FPGAs whose delays depend on the place-and-route result. With 72 macrocells and 38 user I/O in a compact 7x7 mm 48-ball CSBGA, one device typically absorbs address latches, chip selects, bus transceivers control, and status multiplexers from a 3.3V embedded system. In-system programming via JTAG allows logic updates on assembled boards, and the XC9500XL Flash architecture requires no external configuration PROM, simplifying BOM and startup. A 10,000-cycle program/erase endurance supports repeated field reconfiguration throughout product life.
推荐
Address Decoding and Bus Control
In processor systems with memory-mapped peripherals, the XC9572XL-5CS48C provides glitch-free address decoding because the XC9500XL sum-of-products array yields constant, data-independent propagation delay of 5 ns worst case. Its 38 user I/O balls interface directly to 3.3V address, data, and control buses, and individual macrocells offer product-term allocation and local feedback for wide decoders such as full 32-bit address comparisons. Operating at system frequencies up to 178.6 MHz, the device comfortably supports decode-and-assert timing in 25 MHz to 100 MHz bus systems with margin. Commercial 0C to +70C rating fits office and lab equipment, and JTAG in-system programming allows decode maps to be updated when the memory map changes during development.
推荐
Power Sequencing and Reset Management
Multi-rail embedded boards need a supervisor that asserts resets, enables regulators, and monitors power-good signals in a defined order. The XC9572XL-5CS48C implements such state machines in its 72 macrocells with deterministic 5 ns transitions and nonvolatile configuration that is active immediately at power-up - no configuration load time like an SRAM FPGA, so resets are never missed during startup. Its 3.3V supply matches typical supervisor and regulator logic levels, and the 38 I/O allow monitoring several rails plus driving multiple enable and reset lines from one 7x7 mm BGA. Flash retention of 20 years and 10,000-cycle endurance let sequencing logic be revised in the field if the power tree changes.
推荐
Industrial Control I/O Expansion
PLCs and industrial controllers use the XC9572XL-5CS48C to expand local I/O: the 38 user pins drive relays, optocoupler LEDs, and read switches or encoders, while the CPLD performs debouncing, quadrature decoding, and PWM generation with fixed 5 ns logic timing independent of logic complexity. The 0.35 um Flash CMOS XC9500XL architecture provides low standby current for always-on control panels, and 3.3V operation integrates with modern MCUs and transceivers such as RS-485 drivers. For deployments outside the commercial temperature range, the pin-compatible XC9572XL-7CS48I variant rated -40C to +85C can be substituted without PCB change, preserving the validated footprint and design files.
推荐
Communication Interface Bridging
Networking and communication boards use the XC9572XL-5CS48C as a bridge between mismatched interface standards: its macrocells implement serial-to-parallel conversion, clock-domain crossings with dual-rank synchronizers, and protocol adaptation at up to 178.6 MHz system frequency. The 5 ns pin-to-pin delay keeps inter-chip handshake timing predictable across PHY, MAC, and controller devices such as Ethernet PHYs and UART extenders. With 38 user I/O at 3.3V, one CSBGA device connects level-compatible peripherals while replacing discrete shift registers and FIFO glue. JTAG ISP permits firmware-side protocol changes to be mirrored by logic updates during development and field service, and the compact 7x7 mm package fits dense line-card layouts.
推荐
Legacy Embedded Board Maintenance
Many installed 3.3V embedded systems from the 2000s were designed around the XC9500XL family, and the XC9572XL-5CS48C keeps those boards serviceable. Because the design files (schematics, VHDL/Verilog, ISE fit results) remain valid across all XC9572XL package and speed variants, repair and rework can substitute the -5CS48C directly or move to the industrial -5CS48I or slower -10CS48C grades within the same 48-ball CSBGA footprint. The device supports 10,000 in-system program/erase cycles and 20-year retention, so replacement CPLDs can be reprogrammed on the board through the existing JTAG header with ISE iMPACT. XAIPART stocks the family to support long-life industrial and transportation products.

设计说明
Decouple the 3.3V rail per AMD DS057 guidelines: place 0.1 uF ceramic capacitors at each VCC ball of the 48-ball CSBGA and one bulk 10 uF capacitor near the device. The XC9500XL ICC depends strongly on operating frequency and output loading, so use the AMD power estimation equations or XPower tool with your actual design before finalizing the regulator budget. Enable the power-saving mode in ISE if standby current matters in your always-on system; unused macrocells should be grounded per the fitting report to minimize dynamic current.
The 48-ball chip-scale BGA (7x7 mm) requires a land pattern taken directly from the AMD package drawing in DS057, not scaled from other XC9572XL packages. Because BGA balls sit under the die, inspect with X-ray or use via-in-pad escape routing on inner layers. Keep the JTAG chain (TCK, TDI, TDO, TMS) routed as a short daisy chain with series termination if the chain extends to other Xilinx devices, and add a board-level test point on TDO for production programming access.
Do not confuse speed-grade and temperature suffixes when ordering: -5CS48C (5 ns commercial), -7CS48I (7 ns industrial), and -10CS48C (10 ns commercial) share the same footprint but differ in timing and temperature. A substitution from -5 to -7 halves your timing margin. Also note the XC9572XV family uses a 1.8V supply in the same package outline - it is NOT electrically compatible with a 3.3V board. Finally, design files must be refitted only with ISE; newer AMD tools do not support XC9500XL, so preserve a working ISE environment.
Drive 38 outputs at 178.6 MHz-class internal timing and the simultaneous-switching noise on the small CSBGA becomes visible on 3.3V rails. AMD application guidance for XC9500XL recommends limiting the number of outputs switching in the same instant, slowing output slew where the I/O configuration allows, and reserving adjacent ground balls for high-activity I/O groups. Series resistors (22-33 ohm) on long traces to external memory or transceivers reduce ringing and EMI without materially affecting the 5 ns logic budget.
合规信息
The base XC9572XL-5CS48C suffix does not carry the G (Pb-free) package designation; the lead-free variant is XC9572XL-5CSG48C. Compliance declarations for each suffix should be confirmed against the AMD product page or requested via quote.
