Product details
Overview
ATF1504AS-15AI100 from Microchip Technology (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 64 macrocells, 7.5 ns pin-to-pin delay, and support for 125 MHz registered operation. It features in-system programmability via IEEE 1149.1 JTAG, three global clock inputs, and operates across -40°C to +85°C industrial temperature range in a 100-lead TQFP package. It serves as a logic integration solution for legacy TTL/SSI/MSI replacement and control-plane logic in embedded systems.
For engineers reviewing the ATF1504AS-15AI100 datasheet, ATF1504AS-15AI100 pinout, ATF1504AS-15AI100 application, or ATF1504AS-15AI100 equivalent, this device is evaluated for CPLD-based state machine implementation, PCI-compliant I/O interfacing, JTAG boundary-scan test integration, and low-power industrial control logic where reprogrammability and deterministic timing are required.
Technical Context
The ATF1504AS-15AI100 implements a macrocell-based architecture with five product terms per macrocell-expandable up to 40 via cascade logic-and supports combinatorial or registered outputs with configurable D/T/latch flip-flops. Its global bus delivers up to 68 input signals plus buried feedback from all 64 macrocells to each logic block's 40-input switch matrix.
It integrates three dedicated global clock pins (GCLK1–GCLK3), input transition detection (ITD) circuits on clocks/I/Os, programmable slew rate per output, and pin-keeper circuits for floating input retention. Power management includes automatic µA standby (L-version), pin-controlled 1 mA power-down mode, and per-macrocell reduced-power bit enabling.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
ATF1504AS-15AI100 is packaged in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, measuring 14 mm × 14 mm. The package supports fine-pitch PCB assembly and thermal dissipation suitable for industrial ambient conditions.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Primary clock source for macrocell register timing; may also serve as general-purpose input when not used as clock. |
| GCLK2 / OE2 / INPUT | Global Clock Input 2 or Output Enable 2 | Dual-function pin: configured as second global clock or shared output enable signal for grouped macrocells. |
| GCLK3 / I/O | Global Clock Input 3 or Bidirectional I/O | Third clock domain input; defaults to I/O if not assigned as clock in design file. |
| GCLR / INPUT | Global Clear Input | Asynchronous reset for all macrocell flip-flops; may be OR'd with product-term reset for selective clearing. |
| OE1 / INPUT | Output Enable 1 | Dedicated output enable control for macrocell groups; configurable per-macrocell via product term selection. |
| PD1 / I/O | Power-down Control 1 | Active-high pin that forces device into <10 mA power-down mode; disables all logic transitions while preserving output states. |
| TDI / I/O | JTAG Test Data In | JTAG boundary-scan and ISP programming input; includes optional internal pull-up if enabled in configuration. |
| TDO / I/O | JTAG Test Data Out | Serial output for JTAG scan chain; tri-stated when not in BST/ISP mode. |

Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate per Output | Enables noise reduction by slowing non-critical outputs; default slow mode avoids EMI in mixed-signal layouts. |
| Per-Macrocell Reduced-Power Bit | Reduces dynamic power consumption of unused or infrequently toggling macrocells without affecting timing. |
| Input Transition Detection (ITD) | Hardware edge-detection on global clocks, inputs, and I/Os - eliminates need for external debounce logic in interrupt-driven systems. |
| Pin-Keeper Circuits | Retains last-driven logic state on unconnected inputs/I/Os - prevents floating nodes, system noise, and unnecessary current draw. |
| VCC Power-up Reset Option | Configurable hysteresis (Small/Large) ensures reliable state-machine initialization at power-on without external RC networks. |

FAQ
What is the maximum operating frequency of the ATF1504AS-15AI100 in registered mode?
The ATF1504AS-15AI100 supports registered operation up to 125 MHz, as confirmed by its –15 speed grade AC specification (fCNT = 125 MHz). This value is measured using global clock inputs and accounts for worst-case process/voltage/temperature conditions. The ATF1504AS-15AI100 achieves this performance with 7.5 ns pin-to-pin delay and optimized routing resources for critical path minimization.
Does the ATF1504AS-15AI100 support both 3.3 V and 5 V I/O interfaces?
Yes, the ATF1504AS-15AI100 supports dual-voltage I/O operation: VCCIO may be set to either 3.0–3.6 V or 4.5–5.5 V, enabling direct interfacing with both modern 3.3 V logic and legacy 5 V TTL/CMOS systems. This capability is explicitly specified in the DC Characteristics table and verified across commercial and industrial temperature ranges.
How does the pin-keeper feature function on the ATF1504AS-15AI100?
The ATF1504AS-15AI100 includes programmable pin-keeper circuits on all inputs and I/Os. When enabled, these circuits retain the last-driven logic state (high or low) after the driving signal is removed - preventing floating nodes, reducing system noise, and eliminating the need for external pull-up resistors. This feature is configured during JEDEC file generation and applies independently per pin.
Is JTAG boundary-scan testing supported on the ATF1504AS-15AI100?
Yes, the ATF1504AS-15AI100 fully supports IEEE Std. 1149.1-1990 and 1149.1a-1993 boundary-scan testing. Each I/O and input pin includes a dedicated boundary-scan cell (BSC), and the device implements all five standard JTAG instructions (SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE, HIGHZ). BSDL files are provided by Microchip for tool integration.
Can the ATF1504AS-15AI100 be used in PCI-compliant designs?
Yes, the ATF1504AS-15AI100 is explicitly certified PCI-compliant per Peripheral Component Interconnect specification. It meets required drive strength, VOL/VOH levels, and output skew constraints for 32-bit/33 MHz PCI bus interfacing - enabling direct connection without external buffers or level shifters, as documented in the PCI Voltage-to-current Curves section of the datasheet.
