Product details
Overview
ATF1504AS-7AC100 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 100-lead TQFP packaging. It serves as a reprogrammable logic integration solution for legacy TTL/SSI/MSI replacement and board-level glue logic in industrial control and communications systems.
For engineers reviewing the ATF1504AS-7AC100 datasheet, ATF1504AS-7AC100 pinout, ATF1504AS-7AC100 application, or ATF1504AS-7AC100 equivalent, key selection criteria include JTAG ISP capability, PCI-compliant I/O drive, programmable slew rate, global clock architecture with three dedicated GCLK pins, and power-down mode via PD1/PD2 pins.
Technical Context
The ATF1504AS-7AC100 implements a hierarchical CPLD architecture with four logic blocks, each fed by a 40-signal global bus carrying inputs, I/O feedback, and buried macrocell outputs. Its macrocell structure supports D/T/latch flip-flops, combinatorial or registered outputs, and foldback logic enabling up to 40-term sum-of-products within cascaded chains.
It features IEEE 1149.1 JTAG boundary-scan compliance, in-system programmability via TDI/TDO/TCK/TMS, and dual-voltage I/O support (3.3 V or 5.0 V). The -7 speed grade guarantees 125 MHz registered operation and 166.7 MHz maximum clock frequency under specified conditions, with automatic reduced-power bit activation per macrocell.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~2000 usable PLD gates for medium-complexity glue logic. |
| Speed Grade | -7 - guarantees 7.5 ns pin-to-pin delay and 125 MHz registered operation for timing-critical control paths. |
| I/O Count | Up to 68 bidirectional I/Os + 4 dedicated inputs - enables flexible interface mapping across multiple buses or protocols. |
| Power Management | Pin-controlled power-down (<10 mA), macrocell-level reduced-power bit, and automatic µA standby - reduces dynamic and static power in idle or low-activity states. |
| JTAG Support | IEEE 1149.1a-1993 compliant boundary-scan and ISP - allows in-circuit programming and board-level test without device removal. |
| PCI Compliance | Meets PCI electrical specifications - supports direct connection to 33 MHz PCI bus without external buffers. |
| Security & Retention | Programmable security fuse + 20-year data retention - prevents unauthorized readback while ensuring long-term configuration integrity. |
Pinout & Package
ATF1504AS-7AC100 is packaged in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, 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 / OE2 / OE1 | Three dedicated high-drive clock inputs; GCLK2 and GCLK1 double as output enable controls for flexible synchronous timing control. |
| PD1, PD2 | Power-down Control Input | Active-high pins that force device into <10 mA power-down mode; latches internal state and holds outputs valid during sleep. |
| TDI, TDO, TCK, TMS | JTAG Test Access Port | Standard 4-pin IEEE 1149.1 interface for boundary-scan testing and in-system programming; TMS/TDI have optional pull-up. |
| I/Oxx | Bidirectional Logic I/O | Configurable as input, output, or bidirectional; supports 3.3 V or 5.0 V signaling, programmable slew rate, and pin-keeper circuitry. |
| GCLR | Global Clear Input | Asynchronous reset signal for all macrocell flip-flops; can be OR'd with product-term logic for conditional reset behavior. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables field firmware updates and design iteration without device removal using standard JTAG interface and SVF files. |
| Flexible Macrocell Architecture | Each of 64 macrocells supports D/T/latch flip-flops, combinatorial outputs with registered feedback, and buried register optimization for logic density. |
| Enhanced Routing Resources | 40-signal global bus + regional foldback bus enables successful pin-locked design modifications and higher logic utilization. |
| Programmable Slew Rate & Open Collector | Reduces EMI and crosstalk on high-speed traces; open-collector option supports wired-AND bus interfaces like I²C or interrupt lines. |
| Input Transition Detection (ITD) | Detects asynchronous edges on global clocks, inputs, and I/Os - enables glitch-free asynchronous event capture without external circuitry. |

FAQ
What is the maximum operating frequency of the ATF1504AS-7AC100?
The ATF1504AS-7AC100 supports a maximum internal global clock frequency of 125 MHz for registered operation and up to 166.7 MHz for non-registered paths, as confirmed by its -7 speed grade AC characteristics table. This performance is achievable under industrial temperature conditions with proper decoupling and signal integrity layout. The ATF1504AS-7AC100 achieves this using optimized routing and low-skew global clock distribution.
Does the ATF1504AS-7AC100 support both 3.3 V and 5.0 V I/O signaling?
Yes, the ATF1504AS-7AC100 supports dual-voltage I/O operation: VCCIO can be configured for either 3.0–3.6 V or 4.75–5.25 V, allowing direct interfacing with mixed-voltage systems. This capability is explicitly defined in the DC Operating Conditions table and verified across commercial and industrial temperature ranges. The ATF1504AS-7AC100 maintains full functionality-including PCI compliance-in both configurations.
How does the power-down mode function on the ATF1504AS-7AC100?
The ATF1504AS-7AC100 enters power-down mode when PD1 or PD2 is driven high, reducing supply current to below 10 mA while latching all internal logic states and maintaining valid output levels. Inputs are blocked except the PD pin itself, and pin-keeper circuits remain active to prevent floating. This behavior is documented in the Power-down Mode section and validated by ICC2 specifications. The ATF1504AS-7AC100 resumes normal operation within 1 µs after PD goes low.
Is the ATF1504AS-7AC100 compatible with PCI bus specifications?
Yes, the ATF1504AS-7AC100 is explicitly stated as PCI-compliant in its feature list and supported by electrical characterization including high-current drive capability and low output-to-output skew. It meets PCI Local Bus Specification Rev. 2.2 requirements for 33 MHz operation without external buffers. This PCI compliance is a distinguishing feature confirmed in the datasheet's dedicated PCI Compliance section and applies directly to the ATF1504AS-7AC100.
Can the JTAG pins on the ATF1504AS-7AC100 be used as general-purpose I/Os?
Yes, the JTAG pins (TDI, TDO, TCK, TMS) on the ATF1504AS-7AC100 can be repurposed as user I/Os when JTAG boundary-scan and ISP functions are disabled in the design file. This configuration frees four additional pins for logic use, as noted in the Programming section. However, doing so forfeits in-system programming and boundary-scan test capability for the ATF1504AS-7AC100.
