XC9572XL-7CS48I - 3.3V 72-Macrocell CPLD | AMD/Xilinx
MPN: XC9572XL-7CS48I ✗ Cuối đờiXC9572XL-7CS48I Tóm tắt
A CPLD (Complex Programmable Logic Device) is a class of programmable logic IC that sits between simple SPLDs such as GAL/PAL devices and full FPGAs in the programmable-logic hierarchy. CPLDs integrate multiple function blocks with a central switch matrix, providing deterministic, pin-to-pin timing that makes them ideal for glue logic, bus interfacing, and state machines.
Key features of the XC9572XL family include 3.3V low-voltage operation with very low static standby current, an industry-standard JTAG ISP interface (IEEE 1149.1 boundary-scan compliant per manufacturer documentation), 100% routable fixed flip-flops in every macrocell, and a guaranteed 10000 program/erase cycles. The -7 speed grade delivers up to 125 MHz system performance in the FastFlash 0.35 micron CMOS process.
Architecturally, the XC9572XL organizes its 72 macrocells into four 36V18 function blocks connected through a global switch matrix. Each macrocell includes a dedicated register with clock, set, and reset flexibility, and product-term steering allows five direct product terms per macrocell with local feedback for high-speed counting and compare functions.
Typical applications include glue logic for microprocessor and DSP systems, address decoding, bus mastering and handshaking, power-up reset and watchdog integration, legacy design migration from EPLD families, and portable instrumentation where 3.3V power budgets matter.
For design work, note that the CSBGA ball-out must be matched to the footprint in the manufacturer datasheet; verify JTAG chain geometry and boundary-scan length before production programming. Development requires Xilinx ISE, which supports the XC9500XL family for synthesis, fitting, and iMPACT programming.

Ứng dụng tiêu biểu
XC9572XL-7CS48I phù hợp cho 6 Áp dụngs: Address Decoding and Glue Logic, Power-Up Sequencing and Reset Management, Industrial Automation Control, Legacy Design Migration, Communication and Networking Interface Logic, Test and Measurement Equipment.
Address Decoding and Glue Logic
The XC9572XL-7CS48I fits address decoding and system glue logic because its 7.5 ns pin-to-pin delay keeps decode timing inside typical microprocessor access cycles without wait states. Its 72 macrocells and 1600 usable gates absorb chip-select generation, bus direction control, and ready/handshake signals that would otherwise need several 74-series devices. The deterministic CPLD timing - unlike FPGA configuration-dependent paths - guarantees fixed delays across power-up and temperature, and the 3.3V supply matches modern processor I/O banks directly. Place the device between CPU and memory/peripheral chip-select nets with all decode product terms implemented in one function block to preserve the single-block 7.5 ns path.

Power-Up Sequencing and Reset Management
With 72 macrocells and instant power-up operation, the XC9572XL-7CS48I implements multi-rail reset supervision, watchdog logic, and power-good gating without configuration delay - a key CPLD advantage over FPGAs that need a boot source. The industrial -40C to +85C range suits factory and outdoor equipment, and the 3.3V supply integrates with supervisor ICs on the same rail. Implement reset trees with counter-based timeout in the macrocell registers, use the global set/reset resources for deterministic release, and keep the supervision clock input on a dedicated I/O. This consolidates discrete supervisor chips and RC timers into one programmable, re-targetable device.

Industrial Automation Control
In PLC I/O modules, motor control panels, and factory automation interfaces, the XC9572XL-7CS48I provides deterministic logic for interlocks, encoder quadrature decoding, and PWM generation. The industrial -40C to +85C rating and 10000 program/erase cycles support field updates of control logic via JTAG ISP without board rework. The 125 MHz system capability comfortably handles quadrature counting and short PWM periods, while the 48-ball CSBGA keeps the footprint compact on dense I/O boards. Route encoder inputs to macrocells in the same function block to use direct product-term paths and minimize register-to-register delay in the counting chain.
Được đề xuất
Legacy Design Migration
The XC9500XL family was positioned by the manufacturer as a migration target for legacy EPLD and 5V CPLD designs moving to 3.3V systems. Designs previously built from 22V10-class PLDs or older XC9500 parts port to the 72-macrocell XC9572XL with tool support in Xilinx ISE. The 48-ball CSBGA version suits compact retrofit boards. When migrating, re-verify pin assignments against the CSBGA ball map because ball-out differs from DIP/PLCC legacy packages, and re-run timing at the -7 speed grade. This part remains a staple in sustaining engineering for products whose original programmable logic is obsolete.

Communication and Networking Interface Logic
The XC9572XL-7CS48I handles protocol adaptation, serial-to-parallel framing, and bus bridging in networking line cards and backplanes. The 7.5 ns pin-to-pin delay supports fast handshaking with PHY and switch devices, and the JTAG boundary-scan capability per the IEEE 1149.1 standard enables board-level interconnect test during manufacturing - valuable on BGA-dense boards. The 3.3V I/O matches common PHY I/O banks, and the 48-ball array provides enough balls for a wide data bus plus JTAG and control. Keep high-speed bus nets short and match trace lengths on parallel buses to respect the deterministic CPLD setup windows.
Được đề xuất
Test and Measurement Equipment
Bench and modular instruments use the XC9572XL-7CS48I for trigger logic, range-switching control, and front-panel interfacing where deterministic timing matters for measurement repeatability. The fixed pin-to-pin 7.5 ns delay means trigger propagation is identical across units and temperature, improving measurement correlation. JTAG ISP allows calibration-related logic updates in the field, and the compact CSBGA suits crowded analog boards. Isolate the CPLD ground from noisy analog returns, and sequence its 3.3V rail after sensitive analog references to avoid transient coupling during power-up of the instrument front end.

Ghi chú thiết kế
For the 48-ball CSBGA, generate the PCB footprint directly from the package drawing in the manufacturer datasheet DS057 - secondary pinouts often transpose the ball map. Use a standard 0.8 mm pitch BGA escape pattern; the 48-ball array typically routes out on four layers without microvias. Tie all VCCINT/VCCIO and GND balls as specified in the datasheet power table; leaving a power ball floating is a common bring-up failure on this family.
Estimate: with all 72 macrocells switching at moderate frequency, the XC9572XL dynamic current is typically tens of milliamps on a 3.3V rail (tens of milliwatts), well within a small regulator's capability, but verify against the datasheet ICC curves for your toggle rate. Decouple each VCC ball group with at least one 0.1 uF ceramic placed within 2 mm of the ball via, plus one bulk 10 uF per rail. The family's low standby current suits battery-backed industrial panels.
The XC9500XL toolchain is Xilinx ISE, not Vivado - schedule your build environment for a legacy OS or virtual machine, since ISE lacks native support on current Windows versions. Also, because this part is discontinued, lock a die-level second source within the same CS48 ball-out family before committing production, and reserve JTAG access (TDI/TDO/TMS/TCK balls) on test points for field reprogramming over the 10000-cycle flash endurance.
