Product details
Overview
ATF1504ASV-15JC68 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) with 15 ns pin-to-pin delay, JTAG-based in-system programmability, and industrial temperature range (-40°C to +85°C). It features flexible macrocell architecture supporting D/T/latch flip-flops, programmable slew rate, open-collector outputs, and three global clock inputs - used for glue logic consolidation, bus interface control, and state machine acceleration in embedded control systems.
For engineers reviewing the ATF1504ASV-15JC68 datasheet, ATF1504ASV-15JC68 pinout, ATF1504ASV-15JC68 application, or ATF1504ASV-15JC68 equivalent, this page delivers verified electrical specs, package-specific terminal mapping, real-world use cases, and validated alternative CPLDs for migration or second-sourcing - all grounded in Microchip's DS20006185A datasheet and official package documentation.
Technical Context
The ATF1504ASV-15JC68 implements a hierarchical logic architecture with 64 macrocells, each containing five product terms expandable via cascade logic up to 40 terms per chain. Its global bus feeds all 64 macrocell feedback paths plus 68 I/O signals into switch matrices that select up to 40 inputs per logic block.
It supports IEEE 1149.1 JTAG boundary-scan testing and ISP programming using TDI/TMS/TCK/TDO pins, with optional pull-ups on TMS/TDI. The device includes three dedicated global clock pins (GCLK1–GCLK3), two power-down pins (PD1/PD2), and four dedicated control inputs (GCLR, OE1, OE2, GCLK2) - all mapped to specific pins in the 68-lead PLCC package.
Key Specifications

Pinout & Package
ATF1504ASV-15JC68 is packaged in a 68-lead plastic leaded chip carrier (PLCC), with 64 bidirectional I/O pins, four dedicated input/control pins (GCLK1, GCLR, OE1, OE2/GCLK2), two power-down pins (PD1, PD2), and four JTAG pins (TDI, TMS, TCK, TDO). VCC and GND are distributed across multiple pins for low-impedance supply routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 26, 32 | JTAG Interface (TDI, TMS, TCK, TDO) | IEEE 1149.1-compliant test and programming access - configurable as I/O if JTAG disabled |
| 2, 40, 43, 44, 87–90 | Global Clock & Control Inputs (GCLK1, GCLK2/OE2, GCLR, OE1) | Dedicated low-skew clock and asynchronous reset paths - selectable per macrocell for timing-critical logic |
| 5, 19 | Power-Down Pins (PD1, PD2) | Active-high enable for sub-5 mA standby - latches internal state and holds outputs during sleep |
| 11, 25 | Power-Down / I/O (PD1/I/O, PD2/I/O) | Bidirectional pins usable as logic I/O when power-down feature is disabled in design file |
| 3, 9, 17, 29, 41 | VCC (VCCIO/VCCINT) | Single 3.3V supply for core and I/O - decoupling required at each pin per layout guidelines |
| 4, 16, 24, 36 | GND | Four ground connections - essential for noise suppression and signal integrity in high-speed CPLD operation |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Configuration | Each macrocell supports D/T/latch flip-flops, buried registered feedback, combinatorial output with registered feedback, and XOR-based arithmetic - enabling efficient state machine and comparator logic |
| Enhanced Routing Resources | Global bus + regional foldback bus + 40-signal switch matrix per logic block - increases successful place-and-route yield for pin-locked designs |
| Programmable Slew Rate & Open-Collector | Per-output slew control reduces EMI; open-collector option enables wired-AND bus interfacing without external components |
| 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 | Programmable weak hold circuits on all inputs/I/Os - prevents floating states and eliminates external pull-up resistors in unused or tri-stated configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JC68 | Lower standby current (5 µA vs. 75 mA typical); automatic power-down on inactivity - requires no PD pin assertion | Better suited for battery-powered or ultra-low-power wake-on-event systems where continuous polling is avoided | Select ATF1504ASVL-15JC68 only if sub-10 µA quiescent current is mandatory and automatic power management suffices |
| XC9572XL-10PC44C | 72 macrocells, 5 ns faster tPD (10 ns), 3.3V-only supply, no PD pins - uses Xilinx WebPACK toolchain instead of Microchip ProChip Designer | Higher logic density and speed for complex state machines; lacks programmable slew rate and pin-keeper circuits | Choose XC9572XL-10PC44C when migrating legacy Xilinx designs or requiring tighter timing closure, but verify JTAG/BSDL compatibility |
Compared with ATF1504ASVL-15JC68, the ATF1504ASV-15JC68 trades lower standby power for explicit PD pin control and broader voltage tolerance (3.0–3.6V). Against XC9572XL-10PC44C, it offers superior I/O flexibility (64 vs. 36 pins), integrated power-down signaling, and Microchip's mature CPLD toolchain - making it preferable for industrial control where configurability and supply margin matter more than raw speed.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15JC68?
The ATF1504ASV-15JC68 supports registered operation up to 77 MHz, with a minimum global clock period of 13 ns (fCNT = 76.9 MHz) and array clock frequency up to 76.9 MHz. These values are specified under industrial conditions (–40°C to +85°C, VCC = 3.0–3.6V) and assume optimal placement and routing. The ATF1504ASV-15JC68 achieves this performance using three global clock inputs and low-skew internal distribution.
Does the ATF1504ASV-15JC68 support in-system programming (ISP)?
Yes, the ATF1504ASV-15JC68 supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TDI, TMS, TCK, TDO). Programming can be performed without removing the device from the PCB using Microchip's download cable, third-party programmers, or ATE systems generating SVF files. The ATF1504ASV-15JC68 ships erased and ready for ISP, and JTAG may be disabled in the design to reclaim those pins as general-purpose I/O.
What package type is used for the ATF1504ASV-15JC68?
The ATF1504ASV-15JC68 uses a 68-lead plastic leaded chip carrier (PLCC) package, identified by the "JC68" suffix. This package provides 64 user I/O pins plus dedicated control, clock, power-down, and JTAG pins - with thermal and mechanical characteristics validated for industrial temperature operation (–40°C to +85°C). Pin 1 is marked by a corner notch, and the package is RoHS-compliant and halide-free.
How does the power-down feature work on the ATF1504ASV-15JC68?
The ATF1504ASV-15JC68 includes two dedicated power-down pins (PD1 and PD2) that, when asserted high, reduce supply current to below 5 mA. During power-down, all internal logic states and registered outputs are latched and held, and outputs retain their last valid state or high-Z condition. Input signals (except PD pins) are blocked, and pin-keeper circuits remain active to prevent floating. This feature is enabled in the design software and disables use of PD pins as logic inputs.
Is the ATF1504ASV-15JC68 pin-compatible with other ATF1504ASV variants?
No - the ATF1504ASV-15JC68 is not pin-compatible with TQFP or PLCC variants bearing different suffixes (e.g., -15JU44 or -15AU100), as pin assignments for global clocks, power-down, and JTAG differ across packages. For example, GCLK1 appears on pin 37 in the 44-lead TQFP but on pin 43 in the 68-lead PLCC. Migration requires PCB layout revision and signal reassignment verified against the respective package drawings in DS20006185A.
