Product details
Overview
ATF1504ASVL-20JU44 from Microchip Technology is a 3.3V, 64-macrocell Complex Programmable Logic Device (CPLD) in 44-lead PLCC package, featuring 15 ns maximum pin-to-pin delay, 77 MHz registered operation, and automatic 5 µA standby current. It supports in-system programming via JTAG and integrates logic from TTL, SSI, MSI, LSI, and classic PLDs in industrial temperature applications.
For engineers reviewing the ATF1504ASVL-20JU44 datasheet, ATF1504ASVL-20JU44 pinout, ATF1504ASVL-20JU44 application, or ATF1504ASVL-20JU44 equivalent, key selection criteria include its 3.0–3.6V supply range, JTAG boundary-scan compliance (IEEE 1149.1), PCI compatibility, programmable slew rate, and dual power-down pins (PD1/PD2) for low-power system control.
Technical Context
The ATF1504ASVL-20JU44 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 logic block.
It features three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, fast registered input from product terms, and programmable pin-keeper circuits. Power management includes edge-controlled standby (5 µA typ.), per-macrocell reduced-power mode, and pin-controlled power-down (<5 mA).

Pinout & Package
ATF1504ASVL-20JU44 is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package with J-lead configuration. Pin 1 is located at the index corner (notch side, top-left when viewed from top); leads are numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TDI/I/O) | JTAG Test Data Input / General I/O | Primary serial input for ISP programming and boundary-scan data; configurable as logic I/O if JTAG disabled |
| 7 (I/O/TMS) | JTAG Test Mode Select / General I/O | Selects TAP controller state; retains full I/O functionality when JTAG not enabled |
| 26 (I/O/TCK) | JTAG Test Clock / General I/O | Drives TAP state transitions; operates at system clock rates up to 25 MHz for reliable ISP |
| 32 (I/O/TDO) | JTAG Test Data Output / General I/O | Serial output for scan-out data; high-impedance when not active in BST mode |
| 5, 19 (PD1/I/O, PD2/I/O) | Power-Down Control / General I/O | Asserting either pin high enters <5 mA power-down mode; disables logic but holds register and output states |
| 37–40 (GCLK1/I, GCLR/I, OE1/I, GCLK2/OE2/I) | Dedicated Global Control Inputs | Fixed-function pins for clock, asynchronous clear, and output enable - not reassignable as general I/O |
| 35 (GCLK3/I/O) | Global Clock 3 / Bidirectional I/O | Third global clock input; also usable as standard I/O when not assigned as clock |
| 4, 16, 24, 36 (GND) | Ground Reference | Four independent ground connections reduce noise coupling and improve signal integrity across logic blocks |
| 9, 17, 29, 41 (VCC) | Power Supply | Four VCC (VCCINT/VCCIO) pins ensure stable 3.3V distribution to core and I/O circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-output switching speed control reduces EMI and crosstalk on high-speed buses without external termination |
| Pin-Keeper Circuits | Prevents floating inputs/I/Os by latching last driven state - eliminates need for external pull-ups and saves board space |
| Three Global Clock Pins | Enables multi-domain synchronous design (e.g., control, data, interface clocks) without consuming macrocell resources |
| Input Transition Detection (ITD) | Hardware-level edge detection on clocks, inputs, and I/Os enables glitch-free asynchronous event capture and wake-on-interrupt |
| VCC Power-Up Reset | Monotonic VCC-triggered initialization ensures deterministic state machine startup and avoids metastability at power-on |
| Security Fuse | One-time programmable fuse prevents unauthorized readback of configuration bitstream while preserving 16-bit User Signature access |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Interface Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-10VQ44C | 64-macrocell CoolRunner-II CPLD; 3.3V supply; 10 ns tPD; no automatic standby (min ICC = 25 µA) | Lacks integrated ITD, pin-keeper, and VCC power-up reset; requires external reset IC | Preferred where ultra-low static power is secondary to higher speed margin and Xilinx toolchain familiarity |
| ATF1508ASVL-20JU44 | Same family, 128-macrocell variant in identical 44-lead PLCC; same 5 µA standby, JTAG, and feature set | Provides double logic density without PCB change - suitable for design scalability or future-proofing | Select when additional macrocells are needed for expanded I/O mapping or complex state machines without layout revision |
Compared with XCR3064XL-10VQ44C, ATF1504ASVL-20JU44 delivers 5× lower standby current and integrated safety features (ITD, pin-keeper, power-up reset); versus ATF1508ASVL-20JU44, it offers cost and power optimization for designs that fully utilize only 64 macrocells.

FAQ
What is the operating voltage range for ATF1504ASVL-20JU44?
The ATF1504ASVL-20JU44 operates from 3.0 V to 3.6 V. This 3.3V nominal range ensures compatibility with PCI signaling standards and common industrial 3.3V power rails. Operation outside this range may cause functional failure or permanent damage, as specified in Absolute Maximum Ratings. The device's internal regulators and logic thresholds are optimized exclusively for this voltage window.
Does ATF1504ASVL-20JU44 support in-system programming (ISP)?
Yes, ATF1504ASVL-20JU44 supports full in-system programming via its 4-pin JTAG interface compliant with IEEE Std. 1149.1. Programming can be performed without removing the device from the PCB using standard SVF files. The JTAG pins (TDI, TMS, TCK, TDO) are configurable as general I/O when ISP is disabled in the design file.
How does the automatic standby mode work in ATF1504ASVL-20JU44?
The ATF1504ASVL-20JU44 automatically enters a 5 µA standby mode when no logic transitions occur - detected via internal activity monitoring. This feature provides proportional power savings in low-activity systems (e.g., <5 MHz clock domains) without software intervention. Standby exits immediately upon first signal transition, restoring full operation with no latency penalty.
What are the functions of the PD1 and PD2 pins on ATF1504ASVL-20JU44?
PD1 and PD2 are dedicated power-down control inputs on ATF1504ASVL-20JU44. When either pin is driven high (with power-down mode enabled in the design), the device enters a <5 mA power-down state: internal logic and outputs are latched, I/Os retain their last state via pin-keeper circuits, and all inputs except PD pins are ignored. These pins cannot serve as logic I/O when power-down is active.
Is ATF1504ASVL-20JU44 RoHS compliant and lead-free?
Yes, ATF1504ASVL-20JU44 is Green (Pb/Halide-Free/RoHS Compliant) per Microchip's DS20006185A datasheet. The 44-lead PLCC package uses lead-free terminations and complies with EU Directive 2011/65/EU. No lead content is present in solderable surfaces or internal die attach materials, and the device meets JEDEC J-STD-020 moisture sensitivity level MSL-3.
