Product details
Overview
ATF1504AS-7QC100 from Microchip (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 PCI-compliant I/O drivers. It serves as a reprogrammable logic integration solution for legacy TTL/SSI/MSI replacement and control-plane logic in industrial embedded systems.
For engineers reviewing the ATF1504AS-7QC100 datasheet, ATF1504AS-7QC100 pinout, ATF1504AS-7QC100 application, or ATF1504AS-7QC100 equivalent, this page delivers verified package mapping (100-lead TQFP), JTAG ISP capability, 3.3V/5.0V I/O flexibility, power-down mode via PD1/PD2, and macrocell-level reduced-power configuration - all critical for board-level timing closure, thermal management, and field-upgradable logic design.
Technical Context
The ATF1504AS-7QC100 implements a hierarchical CPLD architecture with four logic blocks, each fed by a global bus carrying up to 68 inputs plus 64 buried macrocell feedback signals. Its switch matrix selects up to 40 signals per block, enabling high-fan-in sum-of-products logic synthesis with cascade chains supporting up to 40 product terms per chain.
Each macrocell integrates configurable D/T/latch flip-flops, programmable output slew rate, open-collector option, individual output enable (OE1/OE2), and ITD (Input Transition Detection) on global clocks and I/Os. Three dedicated global clock pins (GCLK1–GCLK3) support synchronous logic with register setup/hold times as low as 3 ns at -7 speed grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~1000–1500 usable PLD gates for combinatorial + registered logic integration |
| Speed Grade | -7 - guarantees ≤7.5 ns pin-to-pin delay and 125 MHz maximum registered clock frequency under commercial conditions |
| I/O Voltage Support | 3.3V or 5.0V - enables direct interfacing with mixed-voltage systems without level shifters |
| Power Management | Pin-controlled power-down (<10 mA) + per-macrocell reduced-power bit - reduces dynamic and static power in partial-utilization designs |
| JTAG Compliance | IEEE Std. 1149.1-1990/1149.1a-1993 - enables boundary-scan testing and in-system programming without device removal |
| PCI Compatibility | Meets PCI electrical specs - supports high-current drive (±24 mA) with low skew for add-in card control logic |
| Data Retention | 20 years - ensures nonvolatile configuration persistence across thermal cycling and long-term storage |
Pinout & Package
ATF1504AS-7QC100 is packaged in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, RoHS-compliant lead finish, and thermal pad exposed on underside for enhanced heat dissipation in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Primary synchronous clock source for logic blocks; supports fast input path with 3 ns setup time |
| GCLK2 / OE2 / INPUT | Global Clock Input 2 or Output Enable 2 | Configurable dual-function pin - used either as second global clock or shared OE signal for grouped outputs |
| GCLK3 / I/O | Global Clock Input 3 or Bidirectional I/O | Third clock domain input or general-purpose I/O; enables multi-clock domain designs |
| GCLR / INPUT | Global Clear Input | Asynchronous reset for all macrocell flip-flops; may be OR'd with product-term reset for selective clearing |
| PD1 / I/O | Power-down Control 1 | Active-high pin that forces device into <10 mA standby when asserted; disables logic transitions but retains output states |
| PD2 / I/O | Power-down Control 2 | Redundant power-down trigger; either PD1 or PD2 assertion activates low-power mode |
| TCK / I/O | JTAG Test Clock | Serial clock for boundary-scan and ISP; operates at up to 25 MHz; pull-up optional |
| TMS / I/O | JTAG Test Mode Select | Controls TAP controller state machine; pull-up option prevents floating during system reset |
| TDI / I/O | JTAG Test Data In | Serial input for BSDL instruction/data loading; also functions as general I/O when JTAG disabled |
| TDO / I/O | JTAG Test Data Out | Serial output for boundary-scan data readback; tri-stated when not in test mode |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables full reconfiguration via JTAG without device removal - critical for firmware updates and post-deployment logic fixes |
| Programmable Pin-keeper Circuits | Eliminates need for external pull-ups on unused I/Os, reducing BOM cost and DC power draw while preventing floating-input noise |
| Three Global Clock Pins | Supports independent clock domains for state machines, counters, and interface logic - avoids internal routing bottlenecks |
| ITD (Input Transition Detection) | Detects asynchronous edges on global clocks, inputs, and I/Os - enables glitch-free interrupt generation and edge-triggered sampling |
| VCC Power-up Reset Option | Hysteresis-selectable (Small/Large) reset ensures deterministic initialization of all registers at power-on - essential for FSM reliability |
| Security Fuse + User Signature | One-time programmable fuse prevents unauthorized readback; 16-bit user-accessible signature stores revision/date/project ID |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic integration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-7VQ100C | 64 macrocells, 7 ns speed, 3.3V-only I/O, no 5V tolerance; lower ICC1 (25 µA standby) | Lacks 5V I/O compatibility and PCI drive strength; requires voltage translation for legacy interfaces | Select when system uses only 3.3V peripherals and lowest static power is prioritized over mixed-voltage flexibility |
| EPM3064ATC100-10 | 64 macrocells, 10 ns speed, 5V-tolerant I/O, higher ICC1 (50 mA standby); no built-in ITD or pin-keeper | Higher power consumption; lacks input transition detection and programmable keepers - needs external pull-ups | Choose when cost sensitivity outweighs advanced power/performance features and JTAG ISP is not required |
Compared with XCR3064XL-7VQ100C and EPM3064ATC100-10, the ATF1504AS-7QC100 uniquely combines 3.3V/5.0V I/O support, PCI compliance, ITD circuitry, and pin-keeper logic - making it the only option suitable for mixed-voltage industrial backplanes requiring field-upgradable, low-noise, and EMI-robust control logic.

FAQ
What is the maximum clock frequency supported by the ATF1504AS-7QC100?
The ATF1504AS-7QC100 supports a maximum internal global clock frequency of 125 MHz under commercial temperature conditions, as confirmed by its -7 speed grade rating and tCNT = 8 ns minimum clock period. This applies to registered logic paths using GCLK1–GCLK3; array clock paths also achieve 125 MHz. The device's fMAX specification reaches 166.7 MHz for specific non-registered configurations, but system-level timing closure must account for routing delays and macrocell utilization.
Does the ATF1504AS-7QC100 support both 3.3V and 5.0V I/O operation?
Yes, the ATF1504AS-7QC100 supports dual-voltage I/O: VCCIO can be set to either 3.0–3.6V or 4.75–5.25V, allowing direct interfacing with 3.3V microcontrollers and 5V legacy peripherals without level-shifting circuitry. The datasheet specifies separate VOH/VOL limits and drive strengths for each mode, and PCI compliance is guaranteed at 5V operation.
How does the power-down mode function on the ATF1504AS-7QC100?
The ATF1504AS-7QC100 enters power-down mode when either PD1 or PD2 pin is driven high, reducing supply current to <10 mA. During this state, all internal logic states and output levels are latched and held, inputs (except PD pins) are blocked, and pin-keeper circuits maintain I/O states. Recovery requires pulling PD low, with tDLIV <1 µs latency before valid I/O operation resumes.
Can the JTAG pins on the ATF1504AS-7QC100 be used as general-purpose I/Os?
Yes - the JTAG pins (TCK, TMS, TDI, TDO) are fully reconfigurable as general-purpose I/Os when JTAG boundary-scan and ISP functionality are disabled in the design file. This recovers four additional logic resources. Pull-up options on TMS and TDI are programmable, and the security fuse prevents unauthorized re-enabling of JTAG after programming.
What packaging and thermal characteristics apply to the ATF1504AS-7QC100?
The ATF1504AS-7QC100 uses a 100-lead TQFP (Thin Quad Flat Package) with 0.5 mm lead pitch and an exposed thermal pad. Its thermal resistance θJA is 35°C/W (typical), and it operates across the industrial temperature range (-40°C to +85°C). The package supports standard reflow profiles and is compatible with automated optical inspection (AOI) due to its gull-wing lead geometry.
