Product details
Overview
ATF1504ASL-25AI100 from Microchip (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 64 macrocells, 7.5 ns pin-to-pin delay, and 125 MHz registered operation. It features in-system programmability via JTAG, three global clock inputs, and supports both 3.3V and 5.0V I/O in industrial temperature range (–40°C to +85°C). It is used in legacy PCI-compliant interface logic, board-level glue logic consolidation, and reconfigurable control state machines.
For engineers reviewing the ATF1504ASL-25AI100 datasheet, ATF1504ASL-25AI100 pinout, ATF1504ASL-25AI100 application, or ATF1504ASL-25AI100 equivalent, this page delivers verified functional identity, package-specific pin mapping (100-lead TQFP), real AC/DC timing values at –25 speed grade, power management modes (standby, power-down, per-macrocell reduced-power), and confirmed alternatives for CPLD migration paths.
Technical Context
The ATF1504ASL-25AI100 implements a hierarchical CPLD architecture with four logic blocks, each fed by a 40-signal global bus carrying all I/O, dedicated input, and buried macrocell feedback signals. Its macrocell structure includes five product terms (expandable to 40 via cascade), configurable D/T/latch flip-flops, and XOR-based arithmetic/comparison logic.
It supports IEEE 1149.1 boundary-scan testing and JTAG ISP programming, with optional pull-ups on TMS/TDI pins and VCC power-up reset with selectable hysteresis. The device integrates ITD (Input Transition Detection) circuits on global clocks, inputs, and I/Os, and offers programmable slew rate, open-collector outputs, and pin-keeper circuits to prevent floating inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~1500 usable PLD gates for medium-complexity control logic. |
| Max Pin-to-pin Delay | 7.5 ns (–25 speed grade) - enables reliable operation in 133 MHz system timing paths with margin. |
| Max Registered Frequency | 125 MHz - supports high-speed synchronous control in industrial automation and communications interfaces. |
| I/O Voltage Support | 3.3V or 5.0V - allows direct interfacing with mixed-voltage systems without level shifters. |
| Power Management | 10 µA standby (L version), 1 mA power-down - reduces idle power in battery-backed or energy-sensitive applications. |
| Program/Erase Cycles | 10,000 cycles - ensures field-upgrade durability across multiple design iterations and firmware revisions. |
| Data Retention | 20 years - guarantees nonvolatile configuration integrity over full industrial lifecycle without refresh. |
Pinout & Package
ATF1504ASL-25AI100 is packaged in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, RoHS-compliant, and rated for industrial temperature (–40°C to +85°C). Pin functions include 68 bidirectional I/Os, four dedicated inputs (GCLK1–GCLK3, GCLR), two power-down pins (PD1/PD2), JTAG interface (TCK/TMS/TDI/TDO), and dual VCCIO/VCCINT supplies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1, GCLK2, GCLK3 | Global Clock Input | Three independent clock sources for domain-segregated synchronous logic; each can drive any macrocell's clock or enable. |
| GCLR | Global Clear Input | Asynchronous reset signal shared across all macrocells; may be OR'd with product-term reset for selective clearing. |
| PD1 / PD2 | Power-down Control | Active-high pins enabling sub-10 mA power-down mode; disables internal logic but retains output states and latch values. |
| TCK / TMS / TDI / TDO | JTAG Boundary-scan Interface | IEEE 1149.1-compliant test and programming port; TMS/TDI support optional internal pull-ups. |
| VCCIO / VCCINT | Power Supply Pins | VCCIO sets I/O voltage (3.3V or 5.0V); VCCINT powers core logic (5.0V only); separation enables mixed-I/O voltage operation. |
| I/Oxx | Bidirectional Logic Pin | Configurable as input, combinatorial output, registered output, or open-collector; supports slew rate control and pin-keeper. |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Architecture | Each of 64 macrocells supports D/T/latch flip-flops, XOR-based arithmetic, and buried registered feedback - enabling efficient state machine and datapath implementation. |
| In-System Programmability (ISP) | JTAG-based reprogramming without device removal - accelerates prototyping, enables field firmware updates, and simplifies manufacturing flow. |
| Per-Macrocell Power Control | Reduced-power bit disables unused macrocells - cuts dynamic power proportionally and lowers total ICC in partial-utilization designs. |
| Programmable Pin-keeper Circuits | Prevents floating inputs/I/Os by latching last-driven state - eliminates need for external pull-ups and reduces system noise and DC leakage. |
| PCI Electrical Compliance | Meets PCI bus drive strength and skew requirements - allows direct integration into add-in cards and host bridge logic without external buffers. |
Applications
| Industrial PLC I/O Expansion | Legacy PCI Interface Glue Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504AS-25AI100 | No "L"-version automatic µA standby; higher ICC1 (130 mA vs. 10 µA) in standby mode. | Suitable where lowest quiescent power is not required; identical logic resources and timing. | Select when cost sensitivity outweighs ultra-low-power needs and existing designs use non-L variant. |
| XC95144XL-10TQ100I | Xilinx CoolRunner-II architecture; 144 macrocells; 10 ns tPD; 178 MHz fCNT; different JTAG BSDL and toolchain. | Higher density and speed; requires Xilinx WebPACK/ISE toolflow; no native PCI drive compliance. | Choose for new designs needing >64 macrocells or higher frequency; verify timing closure and PCI signal integrity separately. |
Compared with ATF1504ASL-25AI100, the non-L variant trades ultra-low standby power for lower unit cost, while the XC95144XL offers greater capacity and speed at the expense of toolchain compatibility and PCI-specific electrical tuning.

FAQ
What is the operating temperature range for ATF1504ASL-25AI100?
The ATF1504ASL-25AI100 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–PLD–07/02), where "Industrial" column specifies this range explicitly for VCCIO and timing parameters. The "I" suffix in the part number denotes industrial grade, and the device undergoes full characterization across this range.
Does ATF1504ASL-25AI100 support both 3.3V and 5.0V I/O interfaces?
Yes, ATF1504ASL-25AI100 supports dual I/O voltage operation: VCCIO may be set to either 3.0–3.6V or 4.75–5.25V, as specified in the DC Characteristics table. This allows direct interfacing with 3.3V microcontrollers and 5V legacy peripherals without external level shifters. The core logic (VCCINT) remains fixed at 5.0V ±5%.
How many global clock inputs does ATF1504ASL-25AI100 provide?
The ATF1504ASL-25AI100 provides three dedicated global clock inputs: GCLK1, GCLK2, and GCLK3. These are physically mapped to pins in the 100-lead TQFP package (e.g., pins 87, 86, and 84 per the top-view diagram) and may be assigned individually to any macrocell's clock input via software configuration.
What is the maximum pin-to-pin propagation delay for ATF1504ASL-25AI100?
The maximum pin-to-pin propagation delay for ATF1504ASL-25AI100 is 7.5 ns, as specified for the "–25" speed grade in the AC Characteristics table (tPD1 parameter). This value is guaranteed across the full industrial temperature range and applies to non-registered output paths with VCCIO = 5.0V and CL = 35 pF.
Is ATF1504ASL-25AI100 compatible with IEEE 1149.1 boundary-scan testing?
Yes, ATF1504ASL-25AI100 fully supports IEEE Std. 1149.1-1990 and 1149.1a-1993 boundary-scan testing. It includes dedicated TCK/TMS/TDI/TDO pins, a compliant TAP controller, and a complete BSDL file. All 68 I/O pins and four dedicated inputs have individual boundary-scan cells, enabling full board-level interconnect testing.
