It integrates logic from TTL/SSI/MSI/LSI and classic PLDs in industrial control, FPGA companion logic, and legacy system upgrades.
For engineers reviewing the ATF1504ASV-15AC100 datasheet, ATF1504ASV-15AC100 pinout, ATF1504ASV-15AC100 application, or ATF1504ASV-15AC100 equivalent, this device supports in-system programming via JTAG, offers programmable slew rate and open-collector outputs, includes three global clock inputs with ITD detection, and provides pin-controlled power-down for low-power embedded timing and glue logic functions.
Technical Context
The ATF1504ASV-15AC100 implements a flexible macrocell architecture with five product terms per macrocell-expandable to 40 via cascade chains-and supports D/T/latch flip-flops, combinatorial or registered outputs, and buried feedback for dual-latch logic within one macrocell. Its global bus feeds all 64 macrocells and I/Os, enabling up to 40 signal selections per logic block.
It features three dedicated global clock pins (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 pin-controlled power-down (PD1/PD2), per-macrocell reduced-power mode, and VCC power-up reset with selectable hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15AC100 | Same logic architecture and pinout, but includes automatic 5 µA standby mode (ATF1504ASVL variant); ATF1504ASV requires pin-controlled power-down. | Better suited for battery-backed or ultra-low-quiescent systems where continuous low-power sleep is required without external control signals. | Select ATF1504ASVL-15AC100 only if automatic standby current reduction is mandatory; otherwise, ATF1504ASV-15AC100 offers identical logic density and speed at lower cost. |
| XC95144XL-10TQ100C | Xilinx CoolRunner-II device: 144 macrocells, 10 ns speed grade, 3.3V operation, but uses different architecture (sum-of-products + function generator) and JTAG BSDL. | Higher density and faster timing for complex state machines; lacks ITD and pin-keeper features but offers longer data retention (>20 years vs. 20-year spec). | Choose XC95144XL-10TQ100C when >64 macrocells or tighter setup/hold margins are needed; verify JTAG toolchain compatibility and macrocell resource mapping. |
Compared with ATF1504ASVL-15AC100, the ATF1504ASV-15AC100 trades automatic low-power mode for simpler power control and lower unit cost; versus XC95144XL-10TQ100C, it offers superior input transition detection and pin-keeper integration for industrial I/O conditioning, at lower macrocell count and slightly relaxed timing.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15AC100?
The ATF1504ASV-15AC100 supports registered operation up to 77 MHz and accepts clock inputs up to 100 MHz. Its -15 speed grade guarantees 15 ns maximum pin-to-pin delay under industrial temperature conditions (-40°C to +85°C) with 3.0V–3.6V supply. The actual achievable frequency depends on logic depth and routing; fMAX = 100 MHz applies to simple register-to-register paths per DS20006185A, page 10.
Does the ATF1504ASV-15AC100 support in-system programming (ISP)?
Yes, the ATF1504ASV-15AC100 supports full IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TCK, TMS, TDI, TDO). ISP allows configuration and reprogramming without removing the device from the PCB, enabling field updates and rapid prototyping. JTAG functionality is enabled by default but can be disabled in the design file to reclaim those pins as general-purpose I/O.
How many I/O pins does the ATF1504ASV-15AC100 provide in the 100-lead TQFP package?
The ATF1504ASV-15AC100 in 100-lead TQFP provides 64 user-configurable I/O pins, plus four dedicated input pins (GCLK1, GCLK2/OE2, GCLK3, GCLR) that can optionally serve as global control signals. Per DS20006185A, page 14, Table 1-6, the total number of signal pins is 68, with eight VCC and eight GND pins distributed for power integrity.
What power management features are available on the ATF1504ASV-15AC100?
The ATF1504ASV-15AC100 includes pin-controlled power-down (via PD1/PD2), per-macrocell reduced-power mode, programmable pin-keeper circuits on all I/Os, and VCC power-up reset with selectable hysteresis. It does not include the automatic 5 µA standby mode found in the ATF1504ASVL variant. Power-down reduces ICC to below 5 mA while retaining output states and internal logic values.
Is the ATF1504ASV-15AC100 RoHS compliant and lead-free?
Yes, the ATF1504ASV-15AC100 is Green (Pb/Halide-Free/RoHS Compliant) per Microchip's official documentation (DS20006185A, page 1). It meets EU RoHS Directive 2011/65/EU requirements and contains no intentionally added lead, brominated flame retardants, or other restricted substances above threshold limits.
