Product details
Overview
ATF1504ASL-25AU100 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 and supports registered operation up to 125 MHz, enabling integration of TTL/SSI/MSI logic in industrial control and legacy interface bridging applications.
For engineers reviewing the ATF1504ASL-25AU100 datasheet, ATF1504ASL-25AU100 pinout, ATF1504ASL-25AU100 application, or ATF1504ASL-25AU100 equivalent, key selection criteria include its ISP-enabled JTAG programming, 3.3V/5.0V I/O flexibility, programmable slew rate, pin-keeper circuits, and power-down mode via PD1/PD2 pins - all critical for field-upgradable embedded systems requiring low-power standby and secure configuration.
Technical Context
The ATF1504ASL-25AU100 implements four logic blocks with global and regional routing buses, supporting up to 68 I/Os and four dedicated input pins usable as global clocks (GCLK1–GCLK3), GCLR, or OE signals. Its macrocell architecture includes configurable D/T/latch flip-flops, XOR-based arithmetic logic, and foldback cascade paths enabling sum-of-products logic with up to 40 product terms per chain.
It features IEEE 1149.1-compliant JTAG boundary-scan, PCI compliance, and dual-voltage I/O (3.3V or 5.0V) with VCCIO/VCCINT separation. The "L" suffix denotes automatic μA standby mode, and the -25 speed grade guarantees 7.5 ns tPD1 and 125 MHz fCNT under industrial temperature conditions (-40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells with 5 base + up to 35 expandable product terms per macrocell - enables complex state machines and glue logic replacement. |
| Speed Grade | -25: 7.5 ns max pin-to-pin delay (tPD1), 125 MHz max internal clock frequency (fCNT) - meets timing-critical control path requirements. |
| Package | 100-lead TQFP (14 × 14 mm, 0.5 mm pitch) - surface-mount compatible with standard reflow profiles and high I/O count needs. |

Pinout & Package
ATF1504ASL-25AU100 is housed in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm lead pitch, compliant with JEDEC MO-137. Pin functions are defined per the 100-pin TQFP top-view layout in Figure 1-1 of the datasheet, including dedicated global clock inputs (GCLK1, GCLK2, GCLK3), global clear (GCLR), output enables (OE1, OE2), power-down controls (PD1, PD2), and JTAG signals (TDI, TDO, TCK, TMS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / GCLK2 / GCLK3 | Global Clock Input | Three independent clock sources routed to all macrocells; each can drive register clocks or serve as array clock - supports multi-clock domain designs. |
| GCLR | Global Clear Input | Asynchronous reset signal active-low; may be OR'd with product-term reset for selective macrocell clearing - ensures deterministic state initialization. |
| PD1 / PD2 | Power-down Control | Active-high pins that force device into sub-10 mA standby; disable logic transitions while preserving register and output states - ideal for battery-backed sleep modes. |
| TDI / TDO / TCK / TMS | JTAG Boundary-scan Port | IEEE 1149.1-compliant test and programming interface; TMS/TDI support internal pull-ups - enables production testing and field firmware updates. |
| VCCIO / VCCINT | Power Supply Rails | VCCIO sets I/O voltage (3.0–3.6V or 4.75–5.25V); VCCINT powers core logic at 5.0V ±5% - decouples I/O signaling from internal logic for noise immunity. |
| I/O[0:67] | Bidirectional Logic Pin | 68 configurable I/Os with programmable slew rate, open-collector option, and pin-keeper circuit - eliminates external pull-ups and reduces board-level noise. |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Architecture | D/T/latch-configurable flip-flops, XOR-based arithmetic, buried feedback, and combinatorial outputs with registered feedback - enables efficient implementation of counters, comparators, and synchronous/asynchronous logic. |
| In-System Programmability (ISP) | JTAG-based reprogramming without device removal; supports SVF vector files and third-party tools - accelerates prototyping and enables post-deployment logic updates. |
| Advanced Power Management | μA-level standby ("L"), pin-controlled 1 mA power-down, per-macrocell reduced-power bit, and programmable pin-keeper - reduces system power by >99% during idle periods without sacrificing I/O state integrity. |
| Enhanced Routing Resources | Global bus with up to 40 selectable signals per logic block, regional foldback bus, and ITD (input transition detection) on clocks/I/Os - improves place-and-route success for pin-locked revisions and high-utilization designs. |
| Security & Configuration Integrity | One-time programmable security fuse blocking readback, plus 16-bit user-accessible signature register - protects intellectual property while allowing traceability (e.g., revision ID, build date). |

Yes, the ATF1504ASL-25AU100 supports dual-voltage I/O via separate VCCIO and VCCINT rails. VCCIO can be set to either 3.0–3.6V or 4.75–5.25V, allowing simultaneous interfacing with 3.3V peripherals and 5.0V legacy components - a capability confirmed in Section 11.3 of the datasheet.
How does the power-down mode function on the ATF1504ASL-25AU100?
The ATF1504ASL-25AU100 enters sub-10 mA power-down mode when PD1 or PD2 is driven high. During this state, all internal logic and output states are latched and held, inputs (except PD pins) are blocked, and pin-keeper circuits prevent floating - ensuring zero functional disruption upon wake-up. This behavior is detailed in Section 12.3.
Is JTAG boundary-scan supported on the ATF1504ASL-25AU100?
Yes, the ATF1504ASL-25AU100 fully supports IEEE Std. 1149.1-1990 and 1149.1a-1993 boundary-scan testing via its dedicated TDI, TDO, TCK, and TMS pins. Each I/O and input pin includes a boundary-scan cell, and BSDL files are provided for test pattern generation - as verified in Sections 13 and 14 of the datasheet.
Can the ATF1504ASL-25AU100 be used in place of older ATF1504AS devices?
Yes, the ATF1504ASL-25AU100 is pin-compatible and functionally equivalent to the ATF1504AS-25AU100, with the addition of automatic μA standby mode and enhanced power management.
