Overview
ATF1504ASV-15JC44 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 JTAG-based in-system programmability. It integrates TTL/SSI/MSI logic replacement and supports industrial temperature range (–40°C to +85°C) with EEPROM-based nonvolatile configuration.
For engineers reviewing the ATF1504ASV-15JC44 datasheet, ATF1504ASV-15JC44 pinout, ATF1504ASV-15JC44 application, or ATF1504ASV-15JC44 equivalent, key selection criteria include macrocell count (64), global clock support (3 pins), programmable slew rate, pin-keeper circuits for floating I/O, and PCI-compliant 3.3V operation with IEEE 1149.1 boundary-scan test capability.
Technical Context
The ATF1504ASV-15JC44 implements a hierarchical CPLD architecture with 64 macrocells organized into logic blocks, each fed by a global bus carrying up to 68 signals (I/Os + buried feedback) and selecting 40 inputs via switch matrix. Each macrocell contains five product terms expandable to 40 via cascade chains, OR/XOR logic, D/T/Latch-configurable flip-flops, and combinatorial/registered output modes.
It supports three dedicated global clock pins (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, fast registered input paths, and programmable power-down via PD1/PD2 pins. The device uses electrically erasable EEPROM for configuration storage, enabling 10,000 program/erase cycles and 20-year data retention, with security fuse protection and 16-bit user signature accessible regardless of fuse state.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 26, 32 | JTAG interface (TDI, TMS, TCK, TDO) | Standard 4-pin IEEE 1149.1 test access port - enables in-system programming and boundary-scan diagnostics without removing device from board. |
| 37, 40, 35 | Global clocks (GCLK1, GCLK2, GCLK3) | Dedicated low-skew clock inputs - drive all macrocell registers synchronously; support ITD for edge-triggered event capture. |
| 39 | Global clear (GCLR) | Asynchronous reset input - forces all macrocell flip-flops to known state at power-up or fault recovery; configurable per macrocell. |
| 38, 40 | Global output enables (OE1, OE2) | Active-low control signals - enable/disable groups of I/O buffers simultaneously to manage bus contention or reduce switching noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JC44 | Includes automatic 5 µA standby mode (vs. pin-controlled 100 µA in ATF1504ASV); identical macrocell count, timing, and pinout. | Better suited for battery-powered or ultra-low-quiescent systems where passive power-down is preferred over active control. | Select ATF1504ASVL-15JC44 when lowest possible standby current is required and automatic entry/exit from low-power state is acceptable. |
| XC9572XL-10VQ44C | Xilinx CoolRunner-II CPLD with 72 macrocells, 5 ns tPD, 100 MHz fMAX, and 2.5V/3.3V dual-supply support; different JTAG BSDL and software toolchain. | Higher speed and lower power in active mode, but lacks pin-keeper and ITD features; requires Xilinx WebPACK tools. | Choose XC9572XL-10VQ44C for higher-frequency control logic where Microchip toolchain independence or lower active power is prioritized over legacy compatibility. |
Compared with ATF1504ASVL-15JC44, the ATF1504ASV-15JC44 trades automatic low-power entry for deterministic pin-controlled power-down, while versus XC9572XL-10VQ44C it offers superior I/O robustness (200 mA latch-up immunity, 2000V ESD) and integrated design features like ITD and pin-keeper - critical for industrial and automotive environments.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15JC44?
The ATF1504ASV-15JC44 supports registered operation up to 77 MHz, with a minimum global clock period of 13 ns (–15 speed grade). Its maximum internal array clock frequency is 76.9 MHz, and it achieves 100 MHz maximum clock frequency under specific conditions. These values are confirmed in Table 1-4 of the DS20006185A datasheet and apply directly to the ATF1504ASV-15JC44 in its specified 44-lead PLCC package.
Does the ATF1504ASV-15JC44 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JC44 supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TDI, TMS, TCK, TDO). ISP allows full configuration, erase, and reprogramming without removing the device from the PCB. The JTAG port can be disabled in the design file to reclaim those pins as general-purpose I/O, and SVF files generated by Microchip tools enable ATE-based programming.
What are the power management features unique to the ATF1504ASV-15JC44?
The ATF1504ASV-15JC44 includes pin-controlled power-down (via PD1/PD2), per-macrocell reduced-power bits, programmable pin-keeper circuits, and slew-rate-controlled outputs. Unlike the ATF1504ASVL variant, it does not feature automatic standby mode. Power-down reduces supply current to below 5 mA while retaining register and output states, and pin-keeper circuits eliminate external pull-ups - both critical for industrial systems with intermittent activity.
Can the ATF1504ASV-15JC44 replace older 22V10 or 20V8 PAL devices?
Yes, the ATF1504ASV-15JC44 is functionally and pin-compatible with many classic PAL/PLA devices through appropriate pin mapping and JEDEC file conversion. Its 64 macrocells, 5 product terms per macrocell (expandable to 40), and flexible flip-flop configuration support direct migration from 22V10/20V8 designs. Microchip's WinCUPL and ProChip Designer tools provide legacy JEDEC import and fitting support for such replacements.
What is the significance of the "JC44" suffix in ATF1504ASV-15JC44?
The "JC44" suffix denotes the 44-lead Plastic Leaded Chip Carrier (PLCC) package with J-lead geometry, as defined in Microchip's packaging nomenclature. This package type is distinct from the 44-lead TQFP (JT44) and 100-lead TQFP (JU100) variants. The JC44 package provides through-hole mounting compatibility, thermal performance suitable for industrial ambient temperatures, and mechanical robustness for high-vibration environments.
