Product details
Overview
ATF1504AS-10QC100 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, and support for 125 MHz registered operation. It implements flexible logic functions in industrial control, legacy interface bridging, and board-level glue logic where in-system programmability and deterministic timing are critical.
For engineers reviewing the ATF1504AS-10QC100 datasheet, ATF1504AS-10QC100 pinout, ATF1504AS-10QC100 application, or ATF1504AS-10QC100 equivalent, this page delivers verified package mapping (100-lead TQFP), JTAG-based ISP capability, PCI-compliant I/O drive, three global clock inputs, and power-down mode control - all confirmed for the exact -10 speed grade and QC100 package variant.
Technical Context
The ATF1504AS-10QC100 uses a hierarchical routing architecture with a global bus feeding up to 40 signals into each logic block's switch matrix, plus regional foldback buses enabling 16-term cascade logic per region. Its macrocell supports D/T/latch flip-flops, programmable output slew rate, open-collector outputs, and buried registered feedback within combinatorial outputs.
It integrates IEEE 1149.1a-compliant JTAG boundary-scan, in-system programmability via TDI/TDO/TCK/TMS, and dual power domains (VCCINT/VCCIO) supporting both 3.3 V and 5.0 V I/O operation. The -10 speed grade guarantees tPD1 ≤ 10 ns and fCNT ≥ 100 MHz under industrial temperature conditions.
Key Specifications

Pinout & Package
ATF1504AS-10QC100 is packaged in a 100-lead Thin Quad Flat Package (TQFP), 14 mm × 14 mm, 0.5 mm pitch, lead-free and RoHS-compliant. Pin numbering follows standard TQFP top-view convention with corner pin #1 marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Dedicated low-skew clock input; may also serve as general-purpose input or OE1 when not used as clock. |
| GCLK2 / OE2 / INPUT | Global Clock Input 2 / Output Enable 2 | Multi-function pin: primary use as second global clock; alternative use as OE signal for grouped outputs. |
| GCLK3 / I/O | Global Clock Input 3 / Bidirectional I/O | Third global clock with fallback to configurable I/O; supports input transition detection (ITD) for edge-triggered logic. |
| 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 sub-10 mA standby; disables logic transitions but retains register and output states. |
| TDI / I/O | JTAG Test Data In | Serial input for JTAG instruction/data; configurable as general I/O if JTAG is disabled in design. |
| TDO / I/O | JTAG Test Data Out | Serial output for JTAG scan chain; tri-stated when not active; may be used as I/O if JTAG unused. |
| TCK / I/O | JTAG Test Clock | System clock for JTAG TAP controller; must be driven externally during programming/test; optional I/O when disabled. |
| TMS / I/O | JTAG Test Mode Select | Controls JTAG state machine; pull-up option available; reconfigurable as input/I/O when JTAG inactive. |
| VCCIO | I/O Power Supply | Separate 3.3 V or 5.0 V supply for I/O buffers - enables mixed-voltage operation independent of core logic voltage. |
| VCCINT | Core Logic Power Supply | 5.0 V ±10% supply for internal logic array and macrocells; decoupling required per datasheet layout guidelines. |
| GND | Ground Reference | Multiple dedicated ground pins distributed across package to minimize noise and ensure stable reference for I/O and core logic. |

FAQ
What is the maximum operating frequency supported by the ATF1504AS-10QC100?
The ATF1504AS-10QC100 supports a maximum internal global clock frequency of 100 MHz (tCNT = 10 ns minimum period) and 125 MHz registered operation under specified conditions. Its -10 speed grade guarantees tPD1 ≤ 10 ns for combinational paths and fCNT ≥ 100 MHz across the industrial temperature range (-40°C to +85°C). These values are measured with VCCIO = 5.0 V and confirmed in the official Microchip datasheet Rev. 0950N.
Does the ATF1504AS-10QC100 support both 3.3 V and 5.0 V I/O operation?
Yes, the ATF1504AS-10QC100 supports dual I/O voltage operation: VCCIO may be set to either 3.0–3.6 V or 4.75–5.25 V, enabling direct interfacing with both 3.3 V and 5.0 V logic families. This is implemented via separate VCCIO and VCCINT supplies - a key differentiator from many competing CPLDs. The specification is validated in DC Characteristics Table on page 11 of the datasheet.
How does the power-down mode function on the ATF1504AS-10QC100?
The ATF1504AS-10QC100 features a pin-controlled power-down mode activated by asserting PD1 or PD2 high. When enabled, supply current drops below 10 mA, all internal logic states and outputs are latched, and inputs (except PD pins) are blocked. The macrocell resources associated with PD pins remain usable for foldback and cascade logic. This behavior is documented in section "Power-down Mode" on page 15 of the datasheet.
Is JTAG boundary-scan testing supported on the ATF1504AS-10QC100?
Yes, the ATF1504AS-10QC100 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 (BSC), and the device implements SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE, and HIGHZ JTAG instructions. BSDL files are provided by Microchip for tool integration.
Can the ATF1504AS-10QC100 be used in PCI-compliant designs?
Yes, the ATF1504AS-10QC100 is explicitly certified PCI-compliant, meeting requirements for drive strength, output-to-output skew, and noise immunity. It achieves this through programmable high-drive outputs without increasing pin capacitance or propagation delay - a feature confirmed in the "PCI Compliance" section (page 18) and AC characteristics tables of the datasheet.
