Product details
Overview
ATF1504ASV-15AC44 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) in 44-pin PLCC package, delivering 15 ns pin-to-pin delay, 77 MHz registered operation, and in-system programmability via IEEE 1149.1 JTAG. It integrates TTL/SSI/MSI logic replacement, PCI-compliant interface control, and industrial temperature support (-40°C to +85°C).
For engineers reviewing the ATF1504ASV-15AC44 datasheet, ATF1504ASV-15AC44 pinout, ATF1504ASV-15AC44 application, or ATF1504ASV-15AC44 equivalent, this page provides verified macrocell architecture details, JTAG boundary-scan compliance, power-down mode timing, slew-rate configurable I/O, and PLCC-specific terminal mapping - all confirmed for the exact -15AC44 variant.
Technical Context
The ATF1504ASV-15AC44 implements a 64-macrocell architecture with five product terms per macrocell expandable to 40 via cascade logic chains, global bus routing feeding up to 40 signals per logic block, and three dedicated global clock inputs (GCLK1–GCLK3). Each macrocell supports D/T/Latch flip-flops, combinatorial or registered outputs, and buried feedback independent of output mode.
It features JTAG-based in-system programming (ISP), IEEE 1149.1a boundary-scan testing, programmable pin-keeper circuits, VCC power-up reset with selectable hysteresis, and dual power-down pins (PD1/PD2) enabling sub-5 mA standby current. The -15 speed grade guarantees tPD1 ≤ 15 ns and fCNT ≥ 76.9 MHz under industrial conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15AC44 | Lower typical standby current (5 µA vs. 75 mA), automatic standby entry, and edge-controlled power-down - not present in ATF1504ASV-15AC44 | Preferred for battery-powered or ultra-low-quiescent systems where continuous low-power operation is mandatory | Select ATF1504ASVL-15AC44 only if sub-10 µA standby is required; otherwise ATF1504ASV-15AC44 offers higher noise immunity and broader voltage margin |
| XC9572XL-10PC44I | Xilinx CoolRunner-II architecture; 72 macrocells; 10 ns speed grade; 2.7–3.6V supply; no dedicated PD pins; different JTAG BSDL | Better suited for high-density, low-power portable designs requiring longer data retention and lower ICC in active mode | Choose XC9572XL-10PC44I when migrating to newer toolchains or needing extended temperature support beyond industrial range |
Compared with ATF1504ASVL-15AC44, the ATF1504ASV-15AC44 trades lower standby current for higher noise immunity and simpler power-down control; versus XC9572XL-10PC44I, it retains full backward compatibility with legacy ProChip Designer toolflow and delivers deterministic 15 ns timing with proven EEPROM reliability in mission-critical industrial deployments.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15AC44?
The ATF1504ASV-15AC44 supports a maximum internal global clock frequency of 76.9 MHz (fCNT) and a maximum array clock frequency of 76.9 MHz (fACNT), with a guaranteed 15 ns pin-to-pin delay. Its registered logic paths achieve 77 MHz operation under industrial conditions, making it suitable for real-time control loops and high-speed bus interfaces where deterministic timing is essential. This performance is validated for the exact ATF1504ASV-15AC44 part number in its 44-pin PLCC package.
Does the ATF1504ASV-15AC44 support in-system programming (ISP)?
Yes, the ATF1504ASV-15AC44 fully supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TCK, TMS, TDI, TDO). ISP allows full configuration, reprogramming, and boundary-scan testing without removing the device from the PCB. The JTAG feature is enabled by default but can be disabled in the design file to reclaim those pins as general-purpose I/O - a capability confirmed specifically for the ATF1504ASV-15AC44 variant.
What power management features does the ATF1504ASV-15AC44 offer?
The ATF1504ASV-15AC44 provides pin-controlled power-down (via PD1/PD2), per-macrocell reduced-power bits, programmable output slew rate, and pin-keeper circuits. When PD1 or PD2 is asserted high, supply current drops below 5 mA while latching internal states and preserving output validity. These features are documented for the ATF1504ASV-15AC44 in DS20006185A and validated for industrial temperature operation - distinct from the automatic standby mode found in the ATF1504ASVL variant.
Is the ATF1504ASV-15AC44 RoHS compliant and green certified?
Yes, the ATF1504ASV-15AC44 is RoHS compliant, halide-free, and lead-free (Pb-free), meeting Microchip's Green standard as stated in DS20006185A. It carries full 2000V HBM ESD protection and 200 mA latch-up immunity, and its EEPROM technology is rated for 10,000 program/erase cycles and 20-year data retention - all verified for the ATF1504ASV-15AC44 in its 44-pin PLCC package.
How many I/O pins does the ATF1504ASV-15AC44 have in the 44-pin PLCC package?
The ATF1504ASV-15AC44 in the 44-pin PLCC package provides 32 user-configurable I/O pins, plus four dedicated input pins (GCLK1, GCLK2/OE2, OE1, GCLR) that can also serve as global control signals. This configuration is explicitly defined in Table 1-6 of DS20006185A for the 44-Lead J-lead (PLCC) variant - confirming the exact pin count and functional allocation for the ATF1504ASV-15AC44 part number.
