Product details
Overview
ATF1504AS-10JI84 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, and support for 125 MHz registered operation. It features JTAG-based in-system programmability, PCI compliance, and operates across industrial temperature range (–40°C to +85°C) in an 84-lead PLCC package.
For engineers reviewing the ATF1504AS-10JI84 datasheet, ATF1504AS-10JI84 pinout, ATF1504AS-10JI84 application, or ATF1504AS-10JI84 equivalent, this device serves as a reprogrammable logic integration solution for legacy TTL/SSI/MSI replacement, board-level control sequencing, and PCI-compliant interface glue logic where deterministic timing, low-power standby, and field-upgradable functionality are required.
Technical Context
The ATF1504AS-10JI84 implements a hierarchical CPLD architecture with four logic blocks, each fed by a global bus carrying up to 68 signals (I/Os + buried macrocell feedback) and a regional foldback bus enabling 16-term cascade logic per region. Its macrocell supports D/T/latch flip-flops, programmable output slew rate, open-collector outputs, and individual product-term clock enables.
It integrates IEEE 1149.1–compliant JTAG boundary-scan for test and ISP, three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/I/Os, and dual power-down modes: automatic µA standby ("L" version) and pin-controlled 1 mA mode via PD1/PD2. The -10 speed grade guarantees ≤10 ns tPD1 and ≥100 MHz fCNT.
Key Specifications

Pinout & Package
ATF1504AS-10JI84 is housed in an 84-lead Plastic Leaded Chip Carrier (PLCC) package with 2.54 mm lead pitch, compatible with standard PLCC sockets and wave-solder processes. Pin 1 is marked by corner notch; package body dimensions are 29.31 mm × 29.31 mm × 4.57 mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O/TDI | JTAG Test Data In / General-purpose I/O | Primary serial input for ISP programming and boundary-scan; configurable as bidirectional logic pin when JTAG disabled. |
| GCLK1/I | Global Clock Input 1 | Dedicated low-skew clock source for synchronous logic across all macrocells; accepts external clock or product-term signal. |
| GCLR/I | Global Clear Input | Asynchronous reset for all macrocell flip-flops; may be OR'd with product term for conditional reset. |
| OE1/I | Output Enable 1 | Global output enable controlling multiple macrocell buffers; selectable per-macrocell via product term. |
| GCLK2/OE2/I | Global Clock 2 / Output Enable 2 | Multi-function pin supporting second clock domain or secondary OE control; resolves pin-count constraints. |
| GCLK3/I/O | Global Clock 3 / Bidirectional I/O | Third clock input or general-purpose I/O; enables triple-clock-domain designs (e.g., PCI + system + debug clocks). |
| PD1/I/O | Power-down Control 1 / I/O | Active-high pin that forces device into ≤10 mA power-down mode; disables logic but retains register state and outputs. |
| VCCINT | Core Logic Supply | 5 V supply for internal logic array; decoupling required within 1 cm of pin to maintain timing integrity. |
| VCCIO | I/O Buffer Supply | 5 V supply for output drivers; independent of VCCINT to support mixed-voltage interfacing (not applicable here - 5V-only variant). |
| GND | Ground Reference | Multiple dedicated ground pins (pins 7, 22, 35, 47, 60, 74) minimize ground bounce and ensure stable reference for high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-output control allows slow switching (reduced EMI) on non-critical signals while maintaining fast edges on clock/data paths. |
| Pin-keeper Circuits | Prevents floating inputs/I/Os during power-down or un-driven states - eliminates need for external pull-ups and associated DC leakage. |
| Reduced-power Macrocell Bit | Individually disables unused macrocells to cut dynamic power - critical for battery-backed or thermally constrained applications. |
| PCI Compliance | Meets PCI Local Bus Specification electrical requirements (drive strength, skew, noise margin) without external buffering. |
| Security Fuse | One-time programmable fuse prevents unauthorized readback of configuration bitstream - protects IP in deployed systems. |
| User Signature Area | 16-bit accessible memory for project ID, revision, or date stamp - enables traceability and version control without consuming logic resources. |

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 speed, 44-pin VQFP; lower I/O count (32), no PD pins, 3.3 V only. | Suitable for space-constrained, low-power embedded control - not viable for 5 V PCI or industrial I/O interfacing. | Select if board uses 3.3 V logic and requires smaller footprint; avoid for 5 V legacy interface or power-down control needs. |
| LC4064V-10TN100C | 64 macrocells, 10 ns, 100-pin TQFP; 3.3 V core/I/O, higher I/O count (64), no JTAG security fuse. | Better for high-I/O density designs with modern 3.3 V interfaces; lacks industrial temp rating and PCI compliance. | Prefer for new 3.3 V designs needing >50 I/Os; ATF1504AS-10JI84 remains superior for 5 V industrial environments with security and PCI requirements. |
Compared with XCR3064XL-10VQG44C and LC4064V-10TN100C, the ATF1504AS-10JI84 uniquely combines 5 V tolerance, industrial temperature rating, PCI compliance, pin-controlled power-down, and JTAG security - making it irreplaceable in legacy-replacement and ruggedized control applications where voltage compatibility and field update security are mandatory.

FAQ
What is the operating temperature range for the ATF1504AS-10JI84?
The ATF1504AS-10JI84 is rated for industrial temperature operation from –40°C to +85°C. This is confirmed in the DC Operating Conditions table of the official datasheet (Rev. 0950N), where "Industrial" column specifies this range. The "I" in the part number suffix explicitly denotes industrial qualification, ensuring reliability in harsh environments such as factory floors or outdoor telecom cabinets.
Does the ATF1504AS-10JI84 support in-system programming (ISP)?
Yes, the ATF1504AS-10JI84 fully supports IEEE 1149.1-compliant in-system programming via its dedicated 4-pin JTAG interface (TCK, TMS, TDI, TDO). As stated in the "Programming" section of the datasheet, ISP allows full configuration, blank-check, and erase operations without removing the device from the PCB - enabling rapid prototyping and field firmware updates.
What package type does the ATF1504AS-10JI84 use?
The ATF1504AS-10JI84 uses an 84-lead Plastic Leaded Chip Carrier (PLCC) package, as indicated by the "J" in the part number suffix and verified in the "Available in…" feature list and the 84-lead PLCC pin diagram on page 3 of the datasheet. This package provides socket compatibility, thermal robustness, and proven manufacturability in industrial assembly lines.
Can the ATF1504AS-10JI84 operate with both 3.3 V and 5 V I/O?
No - the ATF1504AS-10JI84 is a 5 V-only device. Its datasheet specifies VCCIO = 5 V ±10% for industrial operation and makes no provision for 3.3 V I/O. While some earlier ATF1504AS variants (e.g., -33 versions) support 3.3 V, the -10JI84 variant is strictly 5 V-tolerant and must be used in 5 V systems.
What is the purpose of the PD1 and PD2 pins on the ATF1504AS-10JI84?
The PD1 and PD2 pins on the ATF1504AS-10JI84 provide pin-controlled power-down functionality. When either pin is driven high, the device enters a low-power mode drawing <10 mA while retaining all register states and output levels. As documented in the "Power-down Mode" section (page 15), this feature is enabled in the design file and disables logic activity without requiring a full reset.
