Product details
Overview
ATF1504ASV-15JU44 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) in 44-pin PLCC package, featuring 15 ns maximum pin-to-pin delay, registered operation up to 77 MHz, and in-system programmability via IEEE 1149.1 JTAG interface. It integrates logic from TTL/SSI/MSI/LSI and classic PLDs in industrial control, legacy interface bridging, and FPGA configuration management.
For engineers reviewing the ATF1504ASV-15JU44 datasheet, ATF1504ASV-15JU44 pinout, ATF1504ASV-15JU44 application, or ATF1504ASV-15JU44 equivalent, key selection factors include its 44-pin PLCC footprint, 3.0–3.6V supply range, JTAG boundary-scan compliance, programmable slew rate per output, and dual power-down pins (PD1/PD2) supporting <5 mA standby current.
Technical Context
The ATF1504ASV-15JU44 implements a macrocell-based architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports combinatorial or registered outputs with buried feedback routing. 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), dedicated global clear (GCLR), two global output enables (OE1/OE2), and ITD circuits on clocks, inputs, and I/Os for input transition detection. The device supports transparent-latch mode, fast registered input from product terms, and VCC power-up reset with selectable hysteresis.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TDI/I/O) | JTAG Test Data In / General-purpose I/O | Primary serial input for ISP programming and boundary-scan data loading; configurable as logic I/O when JTAG disabled |
| 7 (I/O/TMS) | JTAG Test Mode Select / General-purpose I/O | Selects TAP controller state; retains full macrocell functionality (feedback, foldback) even when used as TMS |
| 26 (I/O/TCK) | JTAG Test Clock / General-purpose I/O | Drives TAP controller state transitions; supports high-speed ISP at up to 10 MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JU44 | Includes automatic 5 µA standby mode (vs. pin-controlled 100 µA in ATF1504ASV); identical pinout and logic resources | Better suited for battery-powered or ultra-low-quiescent systems where continuous low-power operation is required | Select ATF1504ASVL-15JU44 if automatic standby suffices; otherwise retain ATF1504ASV-15JU44 for explicit PD pin control. |
| XC9536XL-10VQ44C | Xilinx CoolRunner-II device: 36 macrocells, 5 ns tPD, 3.3V operation, 44-pin VQFP; no built-in power-down pins or ITD circuits | Limited logic density and routing flexibility; lacks dedicated GCLK/GCLR/OE pins and programmable slew rate | Choose XC9536XL-10VQ44C only for cost-sensitive, low-complexity designs where 64-macrocell capacity and advanced power features are unnecessary. |
Compared with ATF1504ASVL-15JU44, the ATF1504ASV-15JU44 trades automatic standby for deterministic PD pin control - critical in systems requiring synchronized power gating. Against XC9536XL-10VQ44C, it delivers 78% more macrocells, integrated clock management, and hardware-enforced security, justifying use in mission-critical industrial logic consolidation.

FAQ
What is the operating voltage range for the ATF1504ASV-15JU44?
The ATF1504ASV-15JU44 operates from 3.0 V to 3.6 V DC. This 3.3V nominal supply range ensures compatibility with standard TTL and CMOS logic families while supporting stable performance across the full industrial temperature range (-40°C to +85°C). Operation outside this range may cause functional failure or permanent damage.
Does the ATF1504ASV-15JU44 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JU44 supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TDI, TMS, TCK, TDO). ISP allows full device reconfiguration without removal from the PCB, enabling field updates, manufacturing test, and rapid design iterations using SVF files generated by Microchip ProChip Designer or third-party tools.
How many I/O pins does the ATF1504ASV-15JU44 provide in its 44-pin PLCC package?
The ATF1504ASV-15JU44 in the 44-pin PLCC (JU44) package provides 32 user-configurable I/O pins plus four dedicated input pins (GCLK1, GCLK2, GCLK3, GCLR/OE1/OE2), totaling 36 signal-capable pins. Ground and power pins are separate and do not count toward I/O capacity.
What is the purpose of the PD1 and PD2 pins on the ATF1504ASV-15JU44?
The PD1 and PD2 pins on the ATF1504ASV-15JU44 serve as programmable power-down controls. When either pin is driven high (with power-down mode enabled in the design file), the device enters a low-current state drawing less than 5 mA while latching all internal logic states and output levels. These pins cannot function as logic inputs/outputs when power-down is active.
Is the ATF1504ASV-15JU44 pin-compatible with other devices in the ATF1504ASV(L) family?
Yes, the ATF1504ASV-15JU44 shares identical pinout and package dimensions with other 44-pin variants in the ATF1504ASV(L) family, including ATF1504ASVL-15JU44 and speed grades -20JU44. All 44-pin PLCC versions maintain full pin-to-pin compatibility, allowing direct substitution where voltage, timing, and feature requirements align.
