Product details
Overview
ATF1504AS-10JC68 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, and support for 125 MHz registered operation. It implements flexible logic functions in industrial control, legacy interface bridging, and board-level glue logic applications.
For engineers reviewing the ATF1504AS-10JC68 datasheet, ATF1504AS-10JC68 pinout, ATF1504AS-10JC68 application, or ATF1504AS-10JC68 equivalent, key selection criteria include JTAG ISP capability, 68-pin PLCC package compatibility, 3.3V/5V I/O flexibility, PCI compliance, and programmable power-down via PD1/PD2 pins.
Technical Context
The ATF1504AS-10JC68 employs a global bus architecture feeding up to 40 signals into each logic block's switch matrix, with buried macrocell feedback routed to the global bus and foldback terms distributed regionally. Its macrocell supports D/T/latch flip-flops, individual output enable, and programmable slew rate.
It integrates IEEE 1149.1-compliant JTAG boundary-scan testing and in-system programming, with TDI/TMS/TCK/TDO pins configurable as I/O when JTAG is disabled. The device includes three global clock inputs (GCLK1–GCLK3), global clear (GCLR), and two programmable power-down pins (PD1, PD2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides sufficient resources for medium-complexity glue logic and state machine integration |
| Pin-to-pin Delay | 7.5 ns (–10 speed grade) - enables reliable timing closure in 100+ MHz system interfaces |
| Max Registered Frequency | 125 MHz - supports high-speed synchronous logic in control and data-path applications |
| I/O Voltage Support | 3.3 V or 5.0 V - allows direct interfacing with mixed-voltage legacy and modern subsystems |
| Program/Erase Cycles | 10,000 cycles - ensures field-upgradability and long-term design reuse across product lifecycles |
| Data Retention | 20 years - guarantees nonvolatile configuration integrity without battery backup |
| ESD Protection | 2000 V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
ATF1504AS-10JC68 is housed in a 68-lead Plastic Leaded Chip Carrier (PLCC) package with 0.050″ lead pitch, compatible with standard PLCC sockets and reflow/reflow-soldering processes. The package supports industrial temperature range (–40°C to +85°C) and features dual VCCIO/VCCINT supply domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–68 (excluding NC) | Bi-directional I/O or dedicated input | 64 usable I/O pins plus 4 dedicated inputs (GCLK1, GCLK2, GCLK3, GCLR); all support pin-keeper and programmable slew rate |
| GCLK1 / GCLK2 / GCLK3 | Global clock input | Three independent clock sources for domain-segregated timing; each can drive any macrocell's clock input |
| GCLR | Global asynchronous clear | Active-low reset signal routable to all macrocells; may be OR'd with product-term reset for selective clearing |
| PD1 / PD2 | Power-down control | High-active pins enabling sub-10 mA standby; disable internal logic while preserving output states and latch values |
| TDI / TMS / TCK / TDO | JTAG boundary-scan interface | IEEE 1149.1-compliant test and programming port; configurable as general-purpose I/O if JTAG disabled |
| VCCIO | I/O power supply | Separate 3.3 V or 5.0 V rail for I/O buffers - decouples I/O voltage from core logic (VCCINT) |
| VCCINT | Core logic power supply | 5.0 V ±10% supply for internal logic array and macrocells; independent of VCCIO for mixed-voltage operation |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability (ISP) | Enables firmware updates and logic revisions without device removal - critical for field-deployed industrial systems |
| Programmable pin-keeper circuits | Eliminates need for external pull-ups on unused inputs/I/Os, reducing BOM cost and board space while preventing floating-node power leakage |
| Per-macrocell reduced-power mode | Allows selective disabling of unused macrocells to cut dynamic power - measurable ICC reduction in partial-utilization designs |
| PCI-compliant output drivers | Meets PCI electrical specs (high sink/source current, low skew) without parallel pin tying - simplifies PCI add-in card design |
| Security fuse + User Signature | Fuse prevents unauthorized readback; 16-bit user-accessible signature register stores revision, project ID, or date for traceability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-10VQG44C | 64 macrocells, 44-pin VQFP, 3.3 V only, 9.5 ns tPD, Xilinx CoolRunner-II architecture | Lacks 5 V tolerance and PLCC packaging; requires PCB redesign for footprint and voltage rails | Preferred where 3.3 V-only operation and smaller footprint are acceptable, and JTAG ISP is mandatory |
| EPM3064ATC100-10N | 64 macrocells, 100-pin TQFP, 3.3 V core/I/O, Intel MAX 3000A architecture, 10 ns tPD | Higher pin count, no 5 V I/O support, different JTAG BSDL implementation, no pin-keeper option | Suitable for new designs prioritizing Intel toolchain compatibility and higher I/O count, but not drop-in replaceable |
Compared with ATF1504AS-10JC68, the XCR3064XL offers lower static power but sacrifices 5 V tolerance and PLCC socketability; the EPM3064ATC100 provides more I/Os and tighter timing but requires full voltage and layout redesign - neither matches the ATF1504AS-10JC68's unique blend of industrial PLCC packaging, mixed-voltage I/O, and proven field-programmability.

FAQ
What is the operating temperature range for ATF1504AS-10JC68?
The ATF1504AS-10JC68 is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed per the device's qualification testing and applies to all DC and AC parameters under specified VCCIO and VCCINT conditions. The "I" suffix in the ordering code confirms industrial-grade screening, and the JC68 package variant is validated across this full range.
Does ATF1504AS-10JC68 support both 3.3 V and 5.0 V I/O interfaces simultaneously?
Yes, ATF1504AS-10JC68 supports mixed-voltage I/O operation: VCCIO may be set to either 3.3 V (3.0–3.6 V) or 5.0 V (4.5–5.5 V), while VCCINT remains fixed at 5.0 V. This allows direct connection to 3.3 V microcontrollers and 5 V legacy peripherals on the same device, with level translation handled internally by the I/O buffer architecture.
Can the JTAG pins on ATF1504AS-10JC68 be used as general-purpose I/Os?
Yes - the TDI, TMS, TCK, and TDO pins on ATF1504AS-10JC68 are configurable as standard I/Os when JTAG boundary-scan and ISP functionality are disabled in the design file. This reconfiguration recovers four additional user pins, subject to the constraint that JTAG cannot be re-enabled without reprogramming the device.
How does the power-down feature work on ATF1504AS-10JC68?
When enabled in the design, ATF1504AS-10JC68 enters sub-10 mA power-down mode when PD1 or PD2 is driven high. Internal logic states and output levels are latched and held; inputs (except PD pins) are ignored. Recovery occurs within 1 µs after PD returns low. The feature is implemented at the macrocell level and preserves pin-keeper behavior during transition.
Is ATF1504AS-10JC68 compliant with the PCI Local Bus Specification?
Yes, ATF1504AS-10JC68 meets PCI electrical requirements including driver strength, output skew, and voltage thresholds. Its programmable high-drive mode satisfies PCI sink/source current demands without external parallelization, and its 7.5 ns tPD ensures timing compliance in 33 MHz PCI slots - confirmed in Atmel Application Note "PCI Interface Design with ATF1504AS".
