Product details
Overview
ATF1504ASV-15JI68 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) with 15 ns pin-to-pin delay, registered operation up to 77 MHz, and 44-pin PLCC packaging. It supports in-system programming via JTAG, features flexible macrocell configuration (D/T/latch flip-flops), and delivers robust EEPROM-based logic integration for industrial control and legacy interface replacement.
For engineers reviewing the ATF1504ASV-15JI68 datasheet, ATF1504ASV-15JI68 pinout, ATF1504ASV-15JI68 application, or ATF1504ASV-15JI68 equivalent, this device serves as a high-density, electrically erasable CPLD for pin-locked logic consolidation, PCI-compliant system glue logic, and field-upgradable state-machine implementations requiring deterministic timing and JTAG boundary-scan testability.
Technical Context
The ATF1504ASV-15JI68 implements a hierarchical routing architecture with global and regional buses: all 64 macrocells feed a shared global bus, and each logic block selects up to 40 signals from it. Its macrocell includes five product terms, OR/XOR/cascade logic, configurable D/T/JK/SR/latch flip-flop, and combinatorial or registered output with buried feedback.
It supports three global clock inputs (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-15JI68 | Includes automatic 5 µA standby mode; same pinout, timing, and logic resources | Better suited for battery-backed or ultra-low-quiescent systems where sleep current matters | Select ATF1504ASVL-15JI68 only if sub-10 µA standby is required; otherwise ATF1504ASV-15JI68 offers identical functionality at lower cost |
| XCR3064XL-10VQ44C | 64-macrocell Xilinx CoolRunner-II CPLD; 10 ns tPD, 3.3V supply, but no ITD or pin-keeper circuits | Lacks input transition detection and programmable keepers - requires external biasing for unused pins | Choose XCR3064XL-10VQ44C only when leveraging Xilinx toolchain or needing marginally faster timing; ATF1504ASV-15JI68 provides superior system-level integration features |
Compared with ATF1504ASVL-15JI68, the ATF1504ASV-15JI68 trades automatic standby for simpler power management control; versus XCR3064XL-10VQ44C, it delivers integrated pin-keeper and ITD functionality that reduces BOM count and improves noise immunity in industrial environments.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15JI68?
The ATF1504ASV-15JI68 supports registered operation up to 77 MHz, verified by its 15 ns maximum pin-to-pin delay specification and 13 ns minimum global clock period. This frequency applies to synchronous logic paths using global clock inputs (GCLK1–GCLK3); array-clock paths support up to 76.9 MHz. The actual achievable frequency depends on design routing and macrocell utilization, but the -15 speed grade guarantees timing closure at 77 MHz for typical industrial logic functions.
Does the ATF1504ASV-15JI68 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JI68 supports full in-system programming via its IEEE 1149.1-compliant 4-pin JTAG interface (TDI, TMS, TCK, TDO). ISP enables programming and reconfiguration without removing the device from the PCB, supporting rapid prototyping and field updates. JTAG can be disabled in the design file to reclaim those pins as general-purpose I/O, though doing so forfeits ISP capability.
What package type does the ATF1504ASV-15JI68 use?
The ATF1504ASV-15JI68 uses a 44-lead PLCC (Plastic Leaded Chip Carrier) package with J-shaped leads. This surface-mount package measures 16.59 mm × 16.59 mm and is compatible with standard reflow soldering processes. Pin 1 is marked by a notch on the package body, and the pinout matches the "44-Lead PLCC" diagram in DS20006185A-page 3.
How many I/O pins does the ATF1504ASV-15JI68 provide?
The ATF1504ASV-15JI68 provides 32 user-configurable I/O pins in its 44-lead PLCC package. Four additional dedicated input pins (GCLK1, GCLK2/OE2, GCLR, OE1) serve dual roles as global control signals or logic inputs. All 32 I/Os support bidirectional operation, slew-rate control, open-collector output, and programmable pin-keeper circuits - enabling flexible interface design without external components.
Is the ATF1504ASV-15JI68 RoHS compliant?
Yes, the ATF1504ASV-15JI68 is Green (Pb/Halide-Free/RoHS Compliant) per Microchip's documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), meeting EU Directive 2011/65/EU requirements. This compliance is confirmed in the "Features" section of DS20006185A-page 1 and applies to all manufacturing lots shipped after 2006.
