Product details
Overview
ATF1504AS-10AI100 from 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 PCI-compliant 3.3V/5.0V I/O support. It serves as a reprogrammable logic integration solution for legacy TTL/SSI/MSI replacement and embedded control in industrial automation interfaces.
For engineers reviewing the ATF1504AS-10AI100 datasheet, ATF1504AS-10AI100 pinout, ATF1504AS-10AI100 application, or ATF1504AS-10AI100 equivalent, key selection criteria include JTAG ISP capability, 100-pin TQFP/PQFP package compatibility, industrial temperature range (-40°C to +85°C), power-down mode via PD1/PD2 pins, and macrocell-level reduced-power configuration.
Technical Context
The ATF1504AS-10AI100 implements a flexible macrocell architecture with five configurable sections per macrocell: product term generation, OR/XOR/CASCADE logic, D/T/latch flip-flop, output select/enable, and logic array inputs. Its global bus carries all 64 macrocell feedback signals plus all I/O and dedicated input pins, feeding into switch matrices that select up to 40 signals per logic block.
It supports three global clock inputs (GCLK1–GCLK3), ITD circuits on clocks/I/Os, fast registered input from product terms, and programmable pin-keeper circuits. The device uses IEEE 1149.1a-compliant JTAG boundary-scan for testing and in-system programming, with optional pull-up on TMS/TDI pins and security fuse protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~1000–1500 usable PLD gates for combinational and registered logic synthesis. |
| Timing Performance | 7.5 ns max pin-to-pin delay (–10 speed grade) - enables reliable operation at 125 MHz registered clock frequency in industrial environments. |
| Power Management | 10 µA standby current (L-mode), 1 mA pin-controlled power-down - reduces system-level idle power without external circuitry. |
| I/O Voltage Support | 3.3V or 5.0V I/O pins - allows direct interfacing with mixed-voltage systems including PCI buses and legacy TTL peripherals. |
| Programmability | In-system programmable via 4-pin JTAG (IEEE 1149.1a) - enables field updates and eliminates socket-based programming in production or maintenance. |

Pinout & Package
ATF1504AS-10AI100 is packaged in a 100-lead TQFP (Thin Quad Flat Package) with 0.5 mm pitch, measuring 14 mm × 14 mm. Pin numbering follows standard counter-clockwise orientation starting from top-left corner (Pin 1). The device supports both TQFP and PQFP footprints; this variant uses TQFP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / GCLK2 / GCLK3 | Global Clock Inputs | Three dedicated low-skew clock inputs; each can serve as register clock or array clock source across all macrocells. |
| GCLR | Global Clear Input | Asynchronous reset signal for all macrocell flip-flops; may be OR'd with individual product-term resets. |
| OE1 / OE2 | Output Enable Inputs | Dedicated pins for global output enable control; also configurable as general-purpose inputs when not used. |
| PD1 / PD2 | Power-down Control | Active-high pins enabling <10 mA power-down mode; disables internal logic while preserving output states and latch values. |
| TCK / TMS / TDI / TDO | JTAG Test Access Port | IEEE 1149.1a-compliant boundary-scan and ISP interface; TMS/TDI have optional internal pull-ups. |
| I/O[1:68] | Bidirectional Logic I/O | Up to 68 user-configurable I/Os with programmable slew rate, open-collector option, and pin-keeper circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Flip-flop | Configurable as D, T, JK, SR, or transparent latch with rising-edge clock; supports buried registered feedback within combinatorial outputs. |
| Enhanced Routing Resources | Global bus with 68+ inputs + 64 macrocell feedbacks, plus regional foldback bus - increases successful place-and-route for pin-locked revisions. |
| PCI Electrical Compliance | High-drive outputs with low skew and programmable strength - meets PCI bus loading requirements without external buffers or termination. |
| Per-Macrocell Power Control | Reduced-power bit per macrocell - cuts dynamic power by disabling unused logic paths, critical for thermal-constrained industrial modules. |
| VCC Power-up Reset | Hysteresis-selectable (Small/Large) reset threshold - ensures deterministic state machine initialization after cold start or brownout recovery. |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Interface Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-10VQ100C | 64 macrocells, 10 ns delay, 3.3V-only supply, CoolRunner-II architecture with lower static current (10 µA typical) | Lacks 5V I/O tolerance and PCI compliance; requires external level shifters for legacy bus interfacing | Preferred for new 3.3V-only designs prioritizing ultra-low static power and longer battery life |
| EPM3064ATC100-10 | 64 macrocells, 10 ns delay, 3.3V core/5V I/O, MAX 3000A family with higher density routing but no pin-keeper circuits | Requires external pull-ups on unused inputs; lacks integrated power-down mode and ITD circuits | Suitable where higher fan-in logic chains are needed and JTAG ISP is secondary to cost-sensitive volume production |
Compared with ATF1504AS-10AI100, the XCR3064XL offers lower static power but sacrifices 5V I/O and PCI compliance, while the EPM3064ATC100 provides denser routing yet lacks pin-keeper and power-down features essential for industrial noise immunity and thermal management.

FAQ
What is the maximum operating frequency of the ATF1504AS-10AI100?
The ATF1504AS-10AI100 supports registered operation up to 125 MHz under industrial conditions (–40°C to +85°C) with 5.0V VCCIO. Its –10 speed grade guarantees 7.5 ns maximum pin-to-pin delay, and AC characteristics confirm fCNT = 125 MHz for global clock frequency. The device achieves this using three dedicated global clock inputs and optimized macrocell routing.
Does the ATF1504AS-10AI100 support in-system programming (ISP)?
Yes, the ATF1504AS-10AI100 supports full IEEE 1149.1a-compliant in-system programming via its 4-pin JTAG interface (TCK, TMS, TDI, TDO). ISP allows programming and reconfiguration without removing the device from the PCB. The JTAG port can be disabled in design to reclaim all four pins as general-purpose I/O if boundary-scan or field updates are not required.
What package type does ATF1504AS-10AI100 use, and is it pin-compatible with other ATF1504AS variants?
The ATF1504AS-10AI100 uses a 100-lead TQFP package (14 mm × 14 mm, 0.5 mm pitch). It shares identical pinout with the 100-lead PQFP variant, but differs from 44-/68-/84-lead packages. Pin compatibility is maintained only within the same lead count - e.g., ATF1504AS-10AI100 is pin-compatible with ATF1504AS-10AI100Q (PQFP), but not with ATF1504AS-10AI44.
How does the power-down mode function on the ATF1504AS-10AI100?
The ATF1504AS-10AI100 enters power-down mode when either PD1 or PD2 pin is driven high, reducing supply current to <10 mA. During power-down, all internal logic states and registered outputs are latched and held, and I/Os retain their last-driven or high-Z state. Inputs (except PD pins) are blocked, and pin-keeper circuits prevent floating. The mode is enabled in the design file.
What voltage levels are supported on the I/O pins of the ATF1504AS-10AI100?
The ATF1504AS-10AI100 supports dual I/O voltage operation: 3.3V (3.0V–3.6V) or 5.0V (4.5V–5.5V) VCCIO. This allows direct interfacing with both modern 3.3V logic and legacy 5V TTL/CMOS systems. VCCINT is internally regulated to 5.0V for core logic. The device is PCI-compliant and tolerant of mixed-voltage signaling on shared buses.
