Product details
Overview
ATF1504AS-10AC100 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), and 100-pin TQFP packaging. It delivers 7.5 ns pin-to-pin delay, supports registered operation up to 125 MHz, and features in-system programmability via IEEE 1149.1 JTAG for field reconfiguration in embedded control and interface logic applications.
For engineers reviewing the ATF1504AS-10AC100 datasheet, ATF1504AS-10AC100 pinout, ATF1504AS-10AC100 application, or ATF1504AS-10AC100 equivalent, this device is selected for high-reliability, pin-locked PLD replacements in industrial control, legacy system upgrades, and PCI-compliant interface logic where deterministic timing, nonvolatile configuration, and JTAG debug/test capability are required.
Technical Context
The ATF1504AS-10AC100 implements a hierarchical CPLD architecture with four logic blocks, each fed by a global bus carrying all 68 I/O signals plus 64 buried macrocell feedbacks. Its switch matrix selects up to 40 signals per block, enabling high routing flexibility and successful pin-locked design iterations.
Each macrocell integrates five product terms, OR/XOR/cascade logic, a D/T/latch-configurable flip-flop with global or product-term clocking, and programmable output enable/slew rate. Three dedicated global clock pins (GCLK1–GCLK3), input transition detection (ITD), and VCC power-up reset support robust state machine initialization and timing-critical control functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~2000 usable gates for medium-complexity glue logic integration. |
| Timing Performance | 7.5 ns max pin-to-pin delay (–10 speed grade) - enables synchronous operation at ≤125 MHz register frequency in real-world PCB layouts. |
| Power Management | 10 µA standby current (L-version) - reduces quiescent power in battery-backed or low-duty-cycle industrial systems. |
| I/O Voltage Support | 3.3 V or 5.0 V I/O - allows direct interfacing with mixed-voltage subsystems without level shifters. |
| JTAG Compliance | IEEE Std. 1149.1-1990/1149.1a-1993 - enables boundary-scan testing, ISP programming, and BSDL-based toolchain integration. |
| PCI Compliance | Meets PCI electrical specifications - supports direct connection to PCI bus signals without external driver buffers. |
| Data Retention | 20-year nonvolatile storage - ensures configuration persistence across product lifecycle without refresh. |
Pinout & Package
ATF1504AS-10AC100 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). The package includes dedicated JTAG pins (TCK, TMS, TDI, TDO), three global clock inputs (GCLK1–GCLK3), global clear (GCLR), two power-down control pins (PD1, PD2), and 68 bidirectional I/Os with configurable slew rate and open-collector option.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK | JTAG Test Clock | Synchronizes boundary-scan and ISP data shifts; requires clean, low-jitter clock for reliable programming. |
| TMS | JTAG Test Mode Select | Controls TAP controller state transitions; pull-up option available to ensure default test mode on power-up. |
| TDI | JTAG Test Data In | Serial input for instruction/data loading during ISP or boundary-scan; supports 5 V TTL-level signaling. |
| TDO | JTAG Test Data Out | Serial output for readback and verification; daisy-chain capable for multi-device test configurations. |
| GCLK1–GCLK3 | Global Clock Inputs | Low-skew, dedicated clock sources for synchronous logic; each supports ITD for glitch-free edge detection. |
| GCLR | Global Clear Input | Asynchronous reset for all macrocell flip-flops; may be OR'd with product-term signal for conditional reset. |
| PD1 / PD2 | Power-down Control | Active-high pins that reduce ICC to <10 mA; disables internal logic while latching outputs and preserving I/O states. |
| I/Ox | Bidirectional Logic Pin | Configurable as input, combinatorial output, or registered output; supports pin-keeper, slew control, and open-collector. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables firmware updates and logic revisions without device removal-critical for field-deployed industrial controllers. |
| Programmable Pin-keeper Circuits | Eliminates need for external pull-ups on unused I/Os, reducing BOM cost and board space while preventing floating-input noise. |
| Per-macrocell Reduced-power Bit | Allows selective power gating of inactive logic sections, lowering dynamic power in partial-utilization designs. |
| Security Fuse + User Signature | Fuse prevents unauthorized readback; 16-bit user-accessible signature supports traceability, revision control, and project ID storage. |
| VCC Power-up Reset with Hysteresis Options | Ensures deterministic state-machine initialization; selectable "Large" hysteresis improves noise immunity and reduces ICC by hundreds of µA. |

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-macrocell Xilinx CoolRunner-II; 3.3 V only; no 5 V I/O; lower standby current (10 µA vs. 10 µA), but no pin-keeper option. | Lacks 5 V tolerance and programmable slew rate-requires external level shifting for legacy 5 V systems. | Select when lowest static power and pure 3.3 V operation are prioritized over mixed-voltage flexibility. |
| EPM3064ATC100-10 | 64-macrocell Intel MAX 3000A; 5 V tolerant I/O; 10 ns pin-to-pin delay; no JTAG ISP-requires UV erasure or dedicated programmer. | Non-in-system programmable; lacks security fuse and user signature; higher ICC1 (130 mA vs. 10 µA L-mode). | Select only for cost-sensitive, low-volume production where field updates are unnecessary and UV programming infrastructure exists. |
Compared with XCR3064XL-10VQ100C and EPM3064ATC100-10, the ATF1504AS-10AC100 uniquely combines 5 V/3.3 V I/O, JTAG ISP, pin-keeper circuits, and industrial-grade nonvolatile retention-making it the only choice for field-upgradable, mixed-voltage, safety-critical CPLD deployments.

FAQ
What is the maximum operating frequency of the ATF1504AS-10AC100?
The ATF1504AS-10AC100 supports registered operation up to 125 MHz, as confirmed by its –10 speed grade AC characteristics. This maximum frequency applies to global clock inputs (GCLK1–GCLK3) under standard industrial conditions (–40°C to +85°C, VCCIO = 5.0 V ±5%). The actual achievable system frequency depends on logic depth, routing, and clock enable usage-verified via timing analysis in Atmel WinCUPL or third-party synthesis tools.
Does the ATF1504AS-10AC100 support both 3.3 V and 5.0 V I/O operation?
Yes, the ATF1504AS-10AC100 supports dual-voltage I/O: VCCIO may be set to either 3.0–3.6 V or 4.75–5.25 V, allowing direct interfacing with both 3.3 V microcontrollers and legacy 5 V peripherals. The I/O structure is electrically compatible with TTL and CMOS levels in both modes, and slew rate is independently programmable per pin to minimize switching noise.
How does the power-down feature work on the ATF1504AS-10AC100?
The ATF1504AS-10AC100 includes two dedicated power-down pins (PD1 and PD2). When either is driven high, the device enters a low-current state (<10 mA) while latching all internal logic states and output levels. Inputs (except PD pins) are blocked, but pin-keeper circuits remain active to prevent floating. This mode is enabled in the design source file-not via hardware strap-and preserves configuration nonvolatility.
Is the ATF1504AS-10AC100 JTAG-compatible for boundary-scan testing?
Yes, the ATF1504AS-10AC100 fully complies with IEEE Std. 1149.1-1990 and 1149.1a-1993. It implements a complete boundary-scan chain with dedicated BSCs for all 68 I/O pins and four JTAG pins. The TAP controller resets automatically at power-up (no TRST pin), and BSDL files are provided for integration with commercial boundary-scan tools like Goepel SCANFLEX or JTAG Technologies.
Can the ATF1504AS-10AC100 replace older PLDs like the AMD 22V10 in legacy designs?
Yes, the ATF1504AS-10AC100 is frequently used to replace obsolete 24-pin PLDs such as the AMD 22V10 due to its superior macrocell count (64 vs. 10), expanded product terms (up to 40 vs. 8), and pin-compatible migration paths in 100-pin TQFP footprints. Its enhanced routing resources and pin-keeper option simplify drop-in upgrades without PCB redesign-provided I/O count and voltage requirements align.
