Product details
Overview
ATF1504ASVL-20QC100 from Microchip Technology is a 3.3V, 64-macrocell Complex Programmable Logic Device (CPLD) with 100-pin TQFP packaging, 15 ns maximum pin-to-pin delay, 77 MHz registered operation, and automatic 5 µA standby power mode. It integrates logic from TTL/SSI/MSI/LSI and classic PLDs in industrial control, FPGA companion logic, and legacy system replacement applications.
For engineers reviewing the ATF1504ASVL-20QC100 datasheet, ATF1504ASVL-20QC100 pinout, ATF1504ASVL-20QC100 application, or ATF1504ASVL-20QC100 equivalent, key selection criteria include its 3.0–3.6V supply range, JTAG-based in-system programmability, PCI compliance, 100% tested EEPROM with 10,000 program/erase cycles, and dual power-down capability via PD1/PD2 pins.
Technical Context
The ATF1504ASVL-20QC100 implements a flexible macrocell architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports D/T/latch flip-flops, transparent-latch mode, and combinatorial outputs with registered feedback. Its global bus feeds all 64 macrocells and I/Os, enabling up to 40 signal selections per switch matrix.
It features three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/I/Os, fast registered input from product terms, and programmable pin-keeper circuits. Power management includes edge-controlled standby (5 µA), per-macrocell reduced-power mode, and pin-controlled power-down (100 µA typical).

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20QC100 | No automatic 5 µA standby; uses pin-controlled 100 µA standby only; otherwise identical logic resources and timing | Suitable where standby current is managed externally or not critical; lacks autonomous low-power entry | Select ATF1504ASVL-20QC100 when ultra-low quiescent current during idle periods is mandatory. |
| XC95144XL-10TQ100C | Xilinx CoolRunner-II device; 3.3V operation; 144 macrocells; 10 ns pin-to-pin delay; different JTAG BSDL and fitter toolchain | Better suited for higher-density logic; requires Xilinx WebPACK tools; no built-in pin-keeper or ITD circuits | Choose XC95144XL-10TQ100 only when >64 macrocells are needed and Microchip toolchain independence is acceptable. |
Compared with ATF1504ASV-20QC100, the ATF1504ASVL-20QC100 delivers autonomous power savings without software intervention, while XC95144XL-10TQ100 offers greater density at the cost of ecosystem lock-in and loss of Microchip-specific features like ITD and programmable slew rate.

FAQ
What is the standby current specification for ATF1504ASVL-20QC100?
The ATF1504ASVL-20QC100 features automatic 5 µA standby current (typical) when no logic transitions occur - a key differentiator from the non-L variant. This ultra-low quiescent draw is achieved without external control signals and scales proportionally below 5 MHz system activity. The value is measured at VCC = 3.6V, VIN = 0V or VCC, per DS20006185A Table 1-2.
Does ATF1504ASVL-20QC100 support PCI bus timing requirements?
Yes, ATF1504ASVL-20QC100 is explicitly certified PCI-compliant per DS20006185A. Its AC characteristics - including tCL/tCH ≥ 6 ns, tSU ≥ 13.5 ns (–20 speed grade), and tCOP ≤ 12 ns - meet PCI Specification Rev. 2.2 timing windows for 33 MHz operation. The device uses dedicated GCLK pins and internal routing optimized for synchronous peripheral interfacing.
How many I/O pins does ATF1504ASVL-20QC100 provide in the 100-TQFP package?
The ATF1504ASVL-20QC100 in 100-lead TQFP provides 64 user I/O pins, plus four dedicated input pins (GCLK1, GCLK2/OE2, GCLK3, GCLR) that can also serve as I/O when configured. Per DS20006185A Table 1-6, total signal pins are 68, with eight GND and eight VCC pins allocated separately.
Can ATF1504ASVL-20QC100 be programmed in-system without removing it from the PCB?
Yes, ATF1504ASVL-20QC100 supports full in-system programming (ISP) via its 4-pin JTAG interface (TCK, TMS, TDI, TDO) compliant with IEEE Std. 1149.1. Programming occurs at 3.3V TTL/CMOS levels, requires no device removal, and supports SVF file execution. JTAG pins may be repurposed as I/O if ISP/BST is disabled in the design.
What is the maximum number of product terms usable per macrocell in ATF1504ASVL-20QC100?
Each macrocell in ATF1504ASVL-20QC100 has five base product terms, expandable up to 40 via cascade logic chains - four independent chains exist, each supporting sum-term logic with up to 40 product terms and minimal added delay. This expansion is handled automatically by Microchip's ProChip Designer fitter software.
