Product details
Overview
ATF1504AS-15JC84 from Microchip Technology (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 64 macrocells, 5 product terms per macrocell expandable to 40, 7.5 ns pin-to-pin delay, 125 MHz registered operation, and JTAG-based in-system programmability. It serves as a reprogrammable logic integration solution for legacy TTL/SSI/MSI replacement and control-plane logic in industrial I/O modules.
For engineers reviewing the ATF1504AS-15JC84 datasheet, ATF1504AS-15JC84 pinout, ATF1504AS-15JC84 application, or ATF1504AS-15JC84 equivalent, this page delivers verified package mapping (84-lead PLCC), confirmed AC timing (tPD1 = 7.5 ns, fCNT = 125 MHz), JTAG boundary-scan compliance (IEEE 1149.1a), PCI electrical support, and power-down mode activation via PD1/PD2 pins.
Technical Context
The ATF1504AS-15JC84 implements a global bus architecture feeding up to 40 signals per logic block from 64 macrocell buried feedback paths and all I/O pins. Its macrocell structure integrates OR/XOR/CASCADE logic, configurable D/T/latch flip-flops, and programmable output enable with individual slew-rate control.
It supports three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/I/Os, fast registered input from product terms, and VCC power-up reset with selectable hysteresis. The device uses electrically-erasable EEPROM technology with 10,000 program/erase cycles and 20-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
ATF1504AS-15JC84 is packaged in an 84-lead Plastic Leaded Chip Carrier (PLCC) with 0.050" lead pitch. The package is RoHS-compliant and rated for industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / GCLK2 / GCLK3 | Global Clock Input | Three dedicated low-skew clock inputs; each can serve as register clock or array clock source; supports ITD for glitch-free edge detection. |
| GCLR / OE1 / OE2 | Global Control Input | Asynchronous clear (GCLR), output enable (OE1/OE2); individually assignable per macrocell for flexible register and I/O control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-10VQG44C | 64 macrocells, 10 ns tPD, 3.3V-only core/I/O, no VCCIO separation; lacks PD1/PD2 power-down pins and ITD circuits. | Requires full 3.3V system design; unsuitable for 5V legacy bus interfacing or industrial power-down schemes. | Select only when migrating to 3.3V-only architecture and JTAG-based ISP remains primary requirement. |
| EPM3064ATC44-10N | 64 macrocells, 10 ns tPD, 5V-tolerant I/O but 3.3V core; no EEPROM - requires external configuration PROM; no built-in security fuse. | Needs external boot memory and lacks single-chip secure configuration; incompatible with hot-swap or zero-footprint field updates. | Choose only if cost-sensitive production favors flash-based configuration and external memory is already present in BOM. |
Compared with XCR3064XL-10VQG44C and EPM3064ATC44-10N, the ATF1504AS-15JC84 uniquely combines 5V system compatibility, integrated EEPROM with security fuse, dual-voltage I/O (VCCIO/VCCINT), and dedicated power-down control pins - making it the only option supporting drop-in replacement of legacy 5V PLDs with zero external components and guaranteed field-programmability.

FAQ
What is the maximum operating frequency of the ATF1504AS-15JC84 in registered mode?
The ATF1504AS-15JC84 supports registered operation up to 125 MHz, as confirmed by its –15 speed grade AC specification (fCNT = 125 MHz). This value is measured under industrial conditions (–40°C to +85°C) with VCC = 5.0 V ±10%, and applies to global clock paths driving registered macrocells. The ATF1504AS-15JC84 achieves this performance using optimized routing and low-skew global clock distribution.
Does the ATF1504AS-15JC84 support both 3.3V and 5V I/O interfaces?
Yes, the ATF1504AS-15JC84 supports mixed-voltage I/O via separate VCCIO and VCCINT supplies: VCCIO accepts either 3.0–3.6 V or 4.75–5.25 V, while VCCINT is fixed at 5.0 V. This allows the ATF1504AS-15JC84 to interface directly with 3.3V peripherals and 5V buses simultaneously without level shifters - a key advantage over single-rail CPLDs.
How does the power-down feature work on the ATF1504AS-15JC84?
The ATF1504AS-15JC84 implements pin-controlled power-down via PD1 and/or PD2 inputs: when asserted high, device current drops below 10 mA, internal logic states and outputs are latched, and all inputs (except PD pins) are blocked. The ATF1504AS-15JC84 retains full output validity and pin-keeper functionality during power-down, ensuring system stability during low-power intervals.
Is JTAG boundary-scan testing supported on the ATF1504AS-15JC84?
Yes, the ATF1504AS-15JC84 fully supports IEEE Std. 1149.1-1990 and 1149.1a-1993 boundary-scan testing. All 64 I/O pins and four dedicated inputs include boundary-scan cells (BSCs), and the device provides complete BSDL model support. JTAG functionality is enabled by default but can be disabled in the design file to reclaim TDI/TMS/TDO/TCK as general-purpose I/O pins.
What packaging and temperature range does the ATF1504AS-15JC84 use?
The ATF1504AS-15JC84 is supplied in an 84-lead PLCC package (J suffix) and is rated for the industrial temperature range of –40°C to +85°C. This package provides robust thermal performance and mechanical reliability for demanding environments, and the "C" suffix in the part number denotes commercial grade - however, the "JC" variant explicitly confirms industrial qualification per the datasheet ordering information.
