Product details
Overview
ATF1504ASVL-20AU100 from Microchip Technology is a 3.3V, 64-macrocell Complex Programmable Logic Device (CPLD) in 100-pin TQFP package, featuring 15 ns maximum pin-to-pin delay, 77 MHz registered operation, and automatic 5 µA standby power. It integrates logic from TTL/SSI/MSI/LSI and classic PLDs in industrial control, FPGA companion logic, and legacy system upgrades.
For engineers reviewing the ATF1504ASVL-20AU100 datasheet, ATF1504ASVL-20AU100 pinout, ATF1504ASVL-20AU100 application, or ATF1504ASVL-20AU100 equivalent, key selection criteria include JTAG ISP capability, per-macrocell reduced-power mode, programmable slew rate, pin-keeper circuits, and PCI compliance for embedded logic consolidation.
Technical Context
The ATF1504ASVL-20AU100 implements a flexible macrocell architecture with five product terms per macrocell (expandable to 40 via cascade), OR/XOR/cascade logic, D/T/latch-configurable flip-flops, and combinatorial output with registered feedback within any macrocell. Its global bus feeds all 64 macrocells and I/O pins, enabling up to 40 signal selections per switch matrix.
It supports three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/I/Os, fast registered input from product term, and VCC power-up reset with selectable hysteresis. The device uses EEPROM-based nonvolatile configuration with 10,000 program/erase cycles and 20-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - enables integration of multiple SSI/MSI functions into single device |
| Operating Voltage | 3.0V to 3.6V - compatible with 3.3V industrial bus standards and PCI signaling |
| Max Pin-to-Pin Delay | 20 ns - guarantees timing closure for 50 MHz system clock domains |
| Registered Frequency | 77 MHz - supports high-speed synchronous logic in control and interface applications |
| Standby Current | 5 µA (ATF1504ASVL) - enables ultra-low-power operation during idle periods |

Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables field firmware updates and design iterations without device removal using standard JTAG interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20AU100 | No automatic standby mode; typical standby current 75 mA vs. 5 µA | Suitable where continuous operation is required and ultra-low-power sleep is unnecessary | Select ATF1504ASV-20AU100 only if power budget permits higher static current and automatic power gating is not needed. |
| XCR3256XL-10TQ144I | 256 macrocells, 10 ns speed, 2.7–3.6V operation; no EEPROM - requires external config PROM | Better suited for larger logic density needs; lacks in-system reprogrammability without external memory | Choose XCR3256XL-10TQ144I when >64 macrocells are required and JTAG ISP without external memory is not mandatory. |
Compared with ATF1504ASV-20AU100, the ATF1504ASVL-20AU100 delivers 15,000× lower standby current for battery-backed or energy-sensitive systems; versus XCR3256XL-10TQ144I, it trades density for zero-configuration EEPROM startup and guaranteed pin-compatible migration from legacy ATF1502/1504 families.

FAQ
What is the standby current specification for ATF1504ASVL-20AU100?
The ATF1504ASVL-20AU100 features automatic 5 µA standby current (typical) when no logic transitions occur - a key differentiator from the non-L variant (ATF1504ASV), which draws 75 mA in standby. This ultra-low quiescent current is enabled by internal edge-controlled power-down circuitry and applies across the full industrial temperature range (-40°C to +85°C). The ATF1504ASVL-20AU100 achieves this without external control signals, making it ideal for always-on but intermittently active systems.
Does ATF1504ASVL-20AU100 support in-system programming via JTAG?
Yes, ATF1504ASVL-20AU100 fully supports IEEE Std. 1149.1-1990/1149.1a-1993 compliant in-system programming (ISP) using the standard 4-pin JTAG interface (TCK, TMS, TDI, TDO). Programming occurs at 3.3V TTL/CMOS levels and does not require device removal from the PCB. The JTAG port can be disabled in the design file to reclaim all four pins as general-purpose I/O, though this forfeits ISP capability. ATF1504ASVL-20AU100 ships erased and ready for immediate ISP use.
How many I/O pins does ATF1504ASVL-20AU100 provide in the 100-pin TQFP package?
The ATF1504ASVL-20AU100 in 100-pin TQFP offers 64 user-configurable bidirectional I/O pins plus 4 dedicated input pins (GCLK1, GCLK2/OE2, GCLK3, GCLR), totaling 68 signal pins. Per DS20006185A Table 1-6, the 100-pin variant allocates pins 12 and 42 as PD1/PD2, pins 4, 15, 62, and 73 as JTAG I/O, and eight GND/VCC pairs for power integrity. All I/Os support programmable slew rate, open-collector output, and pin-keeper functionality.
What clocking resources are available on ATF1504ASVL-20AU100?
ATF1504ASVL-20AU100 provides three dedicated global clock inputs (GCLK1, GCLK2, GCLK3), each supporting input transition detection (ITD) for edge-triggered event capture. Any macrocell flip-flop can be clocked by one of these global clocks or by an individual product term. GCLK2 and GCLK3 are multifunction pins (GCLK2/OE2, GCLK3/I/O), allowing dynamic reassignment. The device also supports array clocks derived from product terms, with maximum internal frequencies of 76.9 MHz (global) and 58.8 MHz (array) per AC specs in DS20006185A Table 1-4.
Is ATF1504ASVL-20AU100 RoHS compliant and green-certified?
Yes, ATF1504ASVL-20AU100 is RoHS compliant, Pb-free, and halide-free per Microchip's green manufacturing standards. It meets JEDEC JS-001 ESD ratings (2000V HBM), has 200 mA latch-up immunity, and is rated for industrial temperature operation (-40°C to +85°C). The 100-pin TQFP package uses matte tin lead finish and complies with IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake prior to reflow if exposed beyond floor life.
