It integrates TTL/SSI/MSI logic replacement and supports PCI-compliant system control in industrial temperature range (–40°C to +85°C).
For engineers reviewing the ATF1504ASV-15JI44 datasheet, ATF1504ASV-15JI44 pinout, ATF1504ASV-15JI44 application, or ATF1504ASV-15JI44 equivalent, key selection criteria include macrocell count (64), global clock inputs (3), JTAG boundary-scan compliance (IEEE 1149.1), power-down capability via PD1/PD2 pins, and programmable slew rate per output.
Technical Context
The ATF1504ASV-15JI44 implements a flexible macrocell 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/O pins, enabling high-fan-in logic synthesis with up to 40 signals selected per switch matrix.
It features three dedicated global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, and programmable pin-keeper circuits for floating-input stabilization. The device uses electrically erasable EEPROM technology with 10,000 program/erase cycles and 20-year data retention, supporting secure ISP programming without board removal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JI44 | Lower standby current (5 µA vs. 100 µA typical); automatic standby entry on inactivity; same pinout and logic resources | Better suited for battery-powered or ultra-low-quiescent systems; requires no external PD pin control | Select ATF1504ASVL-15JI44 when minimizing average system power is critical and automatic power management is preferred over manual PD pin control. |
| XC9536XL-10VQ44C | Xilinx CoolRunner-II architecture; 36 macrocells; 10 ns speed grade; different JTAG BSDL and fitting toolchain | Smaller logic capacity; lower I/O count (34 vs. 32 user I/O); optimized for low-power portable designs | Choose XC9536XL-10VQ44C only when design fits within 36 macrocells and requires Xilinx toolchain compatibility; not pin-compatible with ATF1504ASV-15JI44. |
Compared with ATF1504ASVL-15JI44, the ATF1504ASV-15JI44 offers manual power-down control for predictable timing-critical wake-up, while XC9536XL-10VQ44C provides lower static power but lacks PCI compliance and ITD circuitry - making ATF1504ASV-15JI44 preferable for industrial control and bus interface roles requiring deterministic latency and robustness.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15JI44?
The ATF1504ASV-15JI44 supports registered operation up to 77 MHz, verified by its –15 speed grade (15 ns maximum pin-to-pin delay). This frequency applies to synchronous logic driven by global clock inputs GCLK1–GCLK3. The device achieves this performance using enhanced routing resources and low-skew internal clock distribution. Actual system frequency depends on design complexity and placement; the ATF1504ASV-15JI44 datasheet specifies fCNT = 76.9 MHz as the maximum internal global clock frequency under –15 conditions.
Does the ATF1504ASV-15JI44 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JI44 supports full in-system programming via its IEEE 1149.1-compliant 4-pin JTAG interface (TDI, TMS, TCK, TDO). ISP allows reprogramming without removing the device from the PCB, enabling rapid design iterations and field updates. The ATF1504ASV-15JI44 uses industry-standard Serial Vector Format (SVF) files and is compatible with Microchip ProChip Designer, WinCUPL, and third-party tools supporting BSDL. JTAG pins default to boundary-scan/ISP function but can be reassigned as general I/O if disabled in the design.
How many I/O pins does the ATF1504ASV-15JI44 have in its 44-pin PLCC package?
The ATF1504ASV-15JI44 in 44-pin PLCC provides 32 user I/O pins, plus four dedicated control pins (GCLK1, GCLK2, GCLK3, and GCLR) that can optionally serve as general inputs. The package includes four GND and four VCC pins for power integrity. Pin assignments are fixed per datasheet DS20006185A-page 3, with JTAG pins (TDI/TMS/TCK/TDO) sharing I/O functionality when JTAG is disabled in the design configuration.
What power management features are available on the ATF1504ASV-15JI44?
The ATF1504ASV-15JI44 includes pin-controlled power-down mode (via PD1/PD2), programmable macrocell reduced-power bits, and pin-keeper circuits for all inputs and I/Os. When PD1 or PD2 is asserted high, supply current drops below 5 mA while preserving internal logic states and output levels. The reduced-power bit lowers dynamic power per macrocell, and pin-keepers eliminate floating inputs without external resistors. Unlike the ATF1504ASVL variant, the ATF1504ASV-15JI44 does not feature automatic standby entry - power-down is explicitly controlled.
Is the ATF1504ASV-15JI44 RoHS compliant and what is its temperature rating?
Yes, the ATF1504ASV-15JI44 is RoHS compliant (Pb/Halide-Free) and rated for the industrial temperature range of –40°C to +85°C. It meets JEDEC standards for moisture sensitivity level (MSL) and is qualified per AEC-Q100 stress testing for reliability in demanding environments. The device uses robust EEPROM technology with 20-year data retention and 10,000 program/erase cycles, ensuring long-term stability in continuous-operation industrial applications. Its green packaging aligns with global environmental directives without compromising electrical or thermal performance.
