Product details
Overview
ATF1504ASVL-20JC84 from Microchip Technology is a 3.3V, 64-macrocell Complex Programmable Logic Device (CPLD) with 100-pin TQFP packaging, 15 ns pin-to-pin delay, registered operation up to 77 MHz, and automatic 5 µA standby current. 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-20JC84 datasheet, ATF1504ASVL-20JC84 pinout, ATF1504ASVL-20JC84 application, or ATF1504ASVL-20JC84 equivalent, this device supports JTAG ISP programming, PCI-compliant I/O, three global clock inputs, programmable slew rate, and pin-keeper circuits - all critical for field-upgradable, low-power, pin-locked digital logic integration.
Technical Context
The ATF1504ASVL-20JC84 implements a macrocell-based architecture with five product terms per macrocell (expandable to 40 via cascade), dedicated global clock pins (GCLK1–GCLK3), and ITD circuits on clocks, inputs, and I/Os. Its switch matrix selects up to 40 signals from a global bus fed by all 64 macrocell feedback paths and all I/O pins.
Each macrocell supports D/T/Latch flip-flops, combinatorial or registered outputs, buried feedback, and fast registered input from product terms. Power management includes edge-controlled power-down, per-macrocell reduced-power mode, and programmable pin-keeper circuits - all configurable in design software without hardware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Operating Voltage | 3.0V to 3.6V - compatible with 3.3V TTL/CMOS systems and PCI signaling |
| Pin-to-Pin Delay | 20 ns maximum - ensures timing closure in high-speed control and interface logic |
| Max Registered Frequency | 77 MHz - supports real-time state machines and synchronous data path logic |
| Standby Current | 5 µA typical - enables ultra-low-power operation during system idle states |
| JTAG Compliance | IEEE Std. 1149.1-1990/1149.1a-1993 - guarantees boundary-scan testability and ISP reliability |
| Package | 100-lead TQFP (8 mm × 8 mm) - provides 64 user I/Os and 4 dedicated control pins in compact footprint |
Pinout & Package
ATF1504ASVL-20JC84 is housed in a 100-lead thin quad flat pack (TQFP) with 0.5 mm pitch, 8 mm × 8 mm body, and exposed thermal pad (JEDEC MO-153AC). Pin 1 is marked by top-side dot; package is RoHS-compliant, Pb-free, and halide-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Primary clock source for register synchronization across all macrocells; supports fast input timing (tFSU = 3 ns) |

| Three Global Clock Pins | Supports multi-clock-domain designs (e.g., control + data + sync clocks) with independent setup/hold timing |
| Input Transition Detection (ITD) | Hardware-level edge detection on clocks, inputs, and I/Os - offloads timing-critical event capture from CPU or FPGA logic |
| Security Fuse Protection | Prevents unauthorized readback of configuration bitstream while preserving 16-bit User Signature access for traceability |
| VCC Power-Up Reset Option | Configurable hysteresis (Small/Large) ensures reliable state machine initialization at 3.0V–3.6V supply ramp rates |
Applications
| Industrial PLC I/O Expansion | FPGA Companion Logic |
|---|---|
Use Scenario: Adding isolated digital input/output channels to modular PLC backplanes with strict ESD and latch-up immunity requirements. IC Role / Device Role / Timing Role: CPLD acts as glue logic between field sensors/actuators and main controller bus, handling debounce, level translation, and interrupt generation. Use Value: 2000V ESD protection and 200 mA latch-up immunity ensure robust operation in electrically noisy factory environments. |
Use Scenario: Offloading fixed-function logic (e.g., PCIe enumeration, AXI address decoding, or DDR PHY control) from FPGA fabric to reduce resource usage and power. IC Role / Device Role / Timing Role: Provides deterministic, low-latency combinational and registered logic with guaranteed 20 ns timing - unaffected by FPGA place-and-route variability. Use Value: 77 MHz registered performance and 15 ns pin-to-pin delay enable tight timing closure for high-speed interface bridging. |
| Legacy System Replacement | PCI Bus Interface Logic |
Use Scenario: Replacing obsolete PAL/GAL devices in avionics or medical equipment where requalification cycles prohibit FPGA adoption. IC Role / Device Role / Timing Role: Emulates exact pinout and timing behavior of legacy PLDs using same JEDEC fuse map format and 10,000-program/erase cycle EEPROM. Use Value: 20-year data retention and 100% tested EEPROM ensure long-term reliability without redesign or recertification. |
Use Scenario: Implementing PCI target interface logic (address/data steering, parity generation, DEVSEL# timing) in add-in cards requiring strict PCI compliance. IC Role / Device Role / Timing Role: Provides PCI-compliant I/O buffers with 3.3V TTL/CMOS levels, programmable slew rate, and 44–100 pin scalability. Use Value: Built-in PCI compliance eliminates need for external bus transceivers and reduces layout complexity for add-in card designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20JC84 | Same logic architecture but lacks automatic 5 µA standby; uses pin-controlled 100 µA standby mode instead | Suitable for non-battery-powered systems where lowest quiescent current is not required | Select when power budget allows higher standby current and JTAG pins must remain available as I/Os |
| XCR3064XL-10VQG44C | 64-macrocell Xilinx CoolRunner-II CPLD with 3.3V operation, 10 ns tPD, but no integrated ITD or pin-keeper circuits | Better suited for high-volume consumer applications with aggressive cost targets and less demanding ESD/latch-up specs | Select when design requires lower propagation delay and compatibility with Xilinx toolchain, accepting trade-offs in analog peripheral integration |
Compared with ATF1504ASV-20JC84, the ATF1504ASVL-20JC84 delivers 20× lower standby current and built-in power-down control, while XCR3064XL-10VQG44C offers faster timing but lacks Microchip's analog-enhanced features like ITD and pin-keeper - making ATF1504ASVL-20JC84 optimal for industrial and legacy-replacement use cases demanding both low power and robustness.

FAQ
What is the operating voltage range for the ATF1504ASVL-20JC84?
The ATF1504ASVL-20JC84 operates from 3.0V to 3.6V DC on both VCCIO and VCCINT rails. This 3.3V nominal range ensures compatibility with PCI signaling standards and TTL/CMOS logic families. Operation outside this range may cause functional failure or permanent damage, as specified in Absolute Maximum Ratings.
Does the ATF1504ASVL-20JC84 support in-system programming (ISP)?
Yes, the ATF1504ASVL-20JC84 supports full IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TCK, TMS, TDI, TDO). ISP allows configuration updates without removing the device from the PCB, enabling field firmware revisions and rapid prototyping - a core feature confirmed in DS20006185A-page 4.
How many I/O pins does the ATF1504ASVL-20JC84 provide in its 100-lead TQFP package?
The ATF1504ASVL-20JC84 in the 100-lead TQFP package provides 64 user I/O pins, plus four dedicated input pins (GCLK1, GCLK2/OE2, GCLK3, GCLR) and two power-down control pins (PD1, PD2), totaling 70 functional signal pins as documented in Table 1-6 of DS20006185A-page 14.
What is the purpose of the pin-keeper circuit in the ATF1504ASVL-20JC84?
The pin-keeper circuit in the ATF1504ASVL-20JC84 maintains the last driven logic state (high or low) on input and I/O pins when they float, eliminating need for external pull-up resistors. This reduces system noise, prevents unintended power consumption, and improves reliability in unconnected or intermittently driven interfaces - a feature explicitly enabled per-pin in design software.
Is the ATF1504ASVL-20JC84 compliant with PCI electrical specifications?
Yes, the ATF1504ASVL-20JC84 is explicitly stated as PCI-compliant in its official datasheet (DS20006185A-page 1). Its 3.3V I/O structure, timing parameters (e.g., tPD1 ≤ 20 ns), and drive strength meet PCI Local Bus Specification Rev. 2.2 requirements for target-mode interface logic without external buffering.
