Product details
Overview
ATF1504ASV-15JC84 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) with 15 ns maximum pin-to-pin delay, registered operation up to 77 MHz, and support for in-system programming via IEEE 1149.1 JTAG interface. It integrates logic from TTL, SSI, MSI, LSI, and classic PLDs in industrial temperature applications requiring deterministic timing and reprogrammability.
For engineers reviewing the ATF1504ASV-15JC84 datasheet, ATF1504ASV-15JC84 pinout, ATF1504ASV-15JC84 application, or ATF1504ASV-15JC84 equivalent, this device delivers verified 64 macrocells, 5 product terms per macrocell (expandable to 40), JTAG boundary-scan compliance, PCI-compliant I/O, and programmable slew rate control - all critical for legacy logic replacement and board-level reconfiguration.
Technical Context
The ATF1504ASV-15JC84 implements a hierarchical routing architecture with global and regional buses: each of its 64 macrocells feeds a buried feedback signal to the global bus, while switch matrices select up to 40 signals per logic block. Its macrocell supports D/T/latch flip-flops, XOR-based arithmetic/comparison, and combinatorial outputs with registered feedback - enabling efficient state machine and glue logic implementation.
It features three global clock pins (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, fast registered inputs 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 - all configurable in design software without hardware changes.
Key Specifications

Pinout & Package
ATF1504ASV-15JC84 is packaged in an 84-lead PLCC (Plastic Leaded Chip Carrier) - confirmed by the "JC84" suffix per Microchip's naming convention and documented pin configuration diagrams for 44- and 100-lead variants. The JC84 package maps to the 44-lead PLCC footprint with 16 additional pins allocated to ground, VCC, and I/O expansion versus the base 44-pin layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / GCLK2 / GCLK3 | Global Clock Inputs | Three dedicated low-skew clock inputs; each can drive all 64 macrocells - eliminates external clock distribution logic |
| GCLR | Global Clear Input | Asynchronous reset signal active-low; may be OR'd with product-term reset for flexible state initialization |
| OE1 / OE2 | Global Output Enable | Two independent output enable controls; selected per macrocell to manage I/O directionality and bus contention |
| PD1 / PD2 | Power-Down Control | Active-high pins that reduce ICC to <5 mA; disable internal logic while latching outputs and preserving I/O states |
| TCK / TMS / TDI / TDO | JTAG Test Access Port | Standard 4-pin IEEE 1149.1 interface; supports boundary-scan test, ISP programming, and BSDL-based verification |
| I/Ox (x=1–32) | Bidirectional Logic I/O | Configurable as input, output, or tristate; supports programmable slew rate, open-collector option, and pin-keeper circuit |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Architecture | Each macrocell supports D/T/latch flip-flops, XOR-based arithmetic, and combinatorial outputs with registered feedback - enabling single-macrocell implementation of latches, counters, and comparators |
| In-System Programmability (ISP) | JTAG-based programming without device removal; allows firmware updates and design iterations in deployed systems using SVF files or microprocessor interfaces |
| Advanced Power Management | Pin-controlled power-down (<5 mA), per-macrocell reduced-power bit, and programmable pin-keeper circuits - reduces dynamic and static power without sacrificing I/O integrity |
| Robust EEPROM Technology | 100% tested 10,000-cycle endurance, 20-year data retention, 2000V ESD protection, and 200 mA latch-up immunity - qualified for industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JC84 | Includes automatic 5 µA standby mode (ATF1504ASV lacks auto-standby); otherwise identical pinout, macrocell structure, and AC specs | Better suited for battery-backed or ultra-low-quiescent systems where sleep current matters more than cost | Select ATF1504ASVL-15JC84 only if sub-10 µA standby is mandatory; ATF1504ASV-15JC84 offers lower unit cost for mains-powered industrial gear |
| XCR3064XL-10VQG44C | 64-macrocell Xilinx CoolRunner-II CPLD; 3.3V core, 10 ns tPD, but uses different fitter toolchain and lacks ITD circuits | Requires full RTL re-synthesis and timing closure; no direct pin mapping due to different global resource allocation | Choose only when migrating to Xilinx ecosystem tools; ATF1504ASV-15JC84 retains WinCUPL/ProChip Designer support and legacy design reuse |
Compared with ATF1504ASVL-15JC84, the ATF1504ASV-15JC84 trades automatic low-power standby for cost efficiency in always-on systems; versus XCR3064XL-10VQG44C, it preserves Microchip's mature toolchain and ITD-enhanced timing predictability for deterministic control logic.

FAQ
What is the operating voltage range for the ATF1504ASV-15JC84?
The ATF1504ASV-15JC84 operates over a 3.0V to 3.6V supply range for both VCCIO and VCCINT. This single-supply 3.3V tolerance ensures compatibility with standard TTL and CMOS logic families while maintaining specified timing performance and I/O drive strength across the full industrial temperature range (-40°C to +85°C). The ATF1504ASV-15JC84 does not support 5V-only or mixed-voltage operation.
Does the ATF1504ASV-15JC84 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JC84 supports IEEE 1149.1-compliant in-system programming via its dedicated TCK/TMS/TDI/TDO JTAG pins. ISP enables full device configuration, erase, and reprogramming without removal from the PCB - critical for manufacturing test, field firmware updates, and design iteration. The ATF1504ASV-15JC84 ships pre-erased and ready for immediate ISP use.
How many I/O pins does the ATF1504ASV-15JC84 provide in its 84-lead PLCC package?
The ATF1504ASV-15JC84 in the 84-lead PLCC package provides 32 user-configurable I/O pins, plus four dedicated input pins (GCLK1, GCLK2, GCLK3, GCLR) and two power-down control pins (PD1, PD2), all mapped to the JC84 footprint. This matches Microchip's documented 44-lead PLCC pinout scaled to the 84-lead variant, with additional pins allocated to ground and VCC for improved noise immunity.
What is the maximum clock frequency supported by the ATF1504ASV-15JC84?
The ATF1504ASV-15JC84 supports registered operation up to 77 MHz, derived from its 15 ns maximum pin-to-pin delay specification. Its internal global clock frequency limit is 76.9 MHz (tCNT = 13 ns minimum period), and array clock frequency reaches 76.9 MHz under -15 speed grade conditions. These values are measured with all timing margins met and reduced-power bits disabled.
Is the ATF1504ASV-15JC84 RoHS compliant and lead-free?
Yes, the ATF1504ASV-15JC84 is Green (Pb/Halide-Free/RoHS Compliant) per Microchip's official documentation. It meets EU RoHS Directive 2011/65/EU requirements with zero lead content and halogen-free packaging materials - verified through material declarations and third-party lab testing.
