Product details
Overview
ATF1504ASVL-20JI68 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) with 100-pin TQFP packaging, 15 ns maximum pin-to-pin delay, automatic 5 µA standby current, and JTAG-based in-system programmability. It integrates TTL/SSI/MSI logic replacement and supports registered operation up to 77 MHz in industrial temperature range (-40°C to +85°C).
For engineers reviewing the ATF1504ASVL-20JI68 datasheet, ATF1504ASVL-20JI68 pinout, ATF1504ASVL-20JI68 application, or ATF1504ASVL-20JI68 equivalent, this page delivers verified macrocell count, power-down behavior, JTAG boundary-scan compliance, global clock architecture, and I/O configuration details required for CPLD-based logic consolidation, state machine implementation, and legacy interface bridging.
Technical Context
The ATF1504ASVL-20JI68 implements a flexible macrocell architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports combinatorial or registered outputs with buried feedback. Its global bus feeds all 64 macrocells and 68 I/Os, enabling high-fan-in sum-of-products logic synthesis.
It features three dedicated global clock pins (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, programmable pin-keeper circuits, and edge-controlled power-down mode activated by PD1/PD2 pins. The device uses EEPROM-based nonvolatile configuration and supports IEEE 1149.1 boundary-scan testing and ISP programming via standard JTAG interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 64 macrocells - provides sufficient resources for medium-complexity glue logic, protocol translation, and control state machines |
| Operating Voltage | 3.0V to 3.6V - compatible with 3.3V system rails and tolerant of typical supply ripple |
| Pin-to-Pin Delay | 15 ns (–20 speed grade) - enables reliable timing closure for 66 MHz synchronous interfaces |
| Standby Current | 5 µA (automatic) - eliminates need for external power gating in battery-backed or low-duty-cycle systems |
| Package | 100-lead TQFP (J suffix) - surface-mount footprint with 0.5 mm pitch, suitable for automated assembly and thermal management |
| JTAG Compliance | IEEE Std. 1149.1-1990/1149.1a-1993 - enables standardized boundary-scan test and field firmware updates without device removal |
| Temperature Range | Industrial (–40°C to +85°C) - validated for deployment in factory automation, motor control, and outdoor embedded equipment |
Pinout & Package
ATF1504ASVL-20JI68 is housed in a 100-lead thin quad flat pack (TQFP) with 0.5 mm lead pitch and exposed pad. Pin 1 is marked by dot or beveled corner; package dimensions are 14 mm × 14 mm × 1.4 mm (max height). Thermal pad is electrically isolated and recommended for PCB ground connection to improve heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Primary clock source for register synchronization; also usable as general-purpose input when not assigned as clock |
| GCLK2 / OE2 / INPUT | Global Clock Input 2 or Output Enable 2 | Dual-function pin: configurable as second global clock or secondary output enable signal across multiple macrocells |
| GCLK3 / I/O | Global Clock Input 3 or Bidirectional I/O | Third clock domain support or general-purpose I/O; retains full macrocell functionality when used as I/O |
| GCLR / INPUT | Global Clear Input | Asynchronous reset for all registers; may be combined with product-term logic for selective reset behavior |
| PD1 / I/O, PD2 / I/O | Power-Down Control Pins | Active-high inputs that force device into sub-5 mA power-down mode; disable logic transitions but retain output states and internal latches |
| TCK / TMS / TDI / TDO | JTAG Test Access Port | Standard 4-pin boundary-scan interface; supports in-system programming, debug visibility, and manufacturing test without external programmers |
| VCC (8 pins) | Core & I/O Power Supply | Single 3.3V rail powers both logic array and I/O buffers; multiple VCC pins reduce supply impedance and improve noise immunity |
| GND (8 pins) | Ground Reference | Dedicated ground connections per quadrant minimize ground bounce and ensure stable timing margins |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-output switching speed control reduces EMI and allows optimization of signal integrity vs. timing margin |
| Pin-Keeper Circuits | Prevents floating inputs/I/Os during tri-state or un-driven conditions, eliminating external pull-ups and reducing static power |
| Reduced-Power Macrocell Bit | Individual macrocell power gating cuts dynamic current in unused logic sections without affecting functional correctness |
| Combinatorial Output with Registered Feedback | Enables dual-latch behavior within single macrocell, supporting compact shift register or pipeline stage implementations |
| VCC Power-Up Reset with Hysteresis | Ensures deterministic register initialization at power-on; large-hysteresis option improves reliability near 3.0V minimum supply |
| Security Fuse | One-time programmable fuse prevents unauthorized readback of configuration bitstream while preserving user signature access |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic consolidation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20JI68 | Lacks automatic 5 µA standby; requires pin-controlled 100 µA standby mode | Suitable where lowest quiescent current is not critical and board-level power control is already implemented | Select when cost sensitivity outweighs ultra-low-power requirement and existing design uses manual standby control |
| XC9572XL-10TQ100C | Xilinx 72-macrocell CPLD with 10 ns tPD, 3.3V-only supply, no built-in pin-keeper or ITD circuits | Better suited for high-speed timing-critical paths but lacks integrated power management and transition detection features | Choose when maximum frequency (100 MHz) is prioritized over power efficiency and diagnostic capability |
Compared with ATF1504ASV-20JI68, the ATF1504ASVL-20JI68 delivers 20× lower standby current and autonomous power gating, while XC9572XL-10TQ100C offers faster propagation but requires external pull-ups and lacks power-down intelligence - making ATF1504ASVL-20JI68 optimal for energy-constrained industrial controllers.

FAQ
What is the standby current specification for ATF1504ASVL-20JI68?
The ATF1504ASVL-20JI68 features automatic 5 µA standby current (typical) when no logic transitions occur - a key differentiator from the non-L variant. This ultra-low quiescent draw is achieved without external control signals and remains valid across the full industrial temperature range (-40°C to +85°C). The ATF1504ASVL-20JI68 enters this state autonomously, making it ideal for battery-operated or energy-harvesting systems where power budgeting is critical.
Does ATF1504ASVL-20JI68 support in-system programming (ISP)?
Yes, ATF1504ASVL-20JI68 supports full IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TCK, TMS, TDI, TDO). Programming can be performed without removing the device from the PCB using standard SVF files, and the security fuse prevents unauthorized configuration readback. The ATF1504ASVL-20JI68 also allows JTAG pins to be repurposed as general I/O if ISP is disabled in the design file.
How many I/O pins does ATF1504ASVL-20JI68 provide in its 100-lead TQFP package?
The ATF1504ASVL-20JI68 in 100-lead TQFP provides 64 user-configurable I/O pins plus four dedicated input pins (GCLK1, GCLK2/OE2, GCLK3, GCLR), totaling 68 signal-capable terminals. All I/Os support programmable slew rate, open-collector output, and pin-keeper functionality. Unused I/Os default to high-impedance and retain their keeper state during power-down mode.
What is the maximum operating frequency of ATF1504ASVL-20JI68?
The ATF1504ASVL-20JI68 supports registered operation up to 77 MHz and achieves a maximum clock frequency of 83.3 MHz (–20 speed grade) under specified conditions. Its 15 ns pin-to-pin delay and 12 ns global clock-to-output delay (tCOP) enable robust timing closure for synchronous designs operating at 66 MHz or below, especially when using global clock resources and reduced-power macrocell settings.
Can ATF1504ASVL-20JI68 be used in place of older ATF1502 or ATF1500 devices?
Yes, ATF1504ASVL-20JI68 is pin-compatible and functionally upward-compatible with ATF1502ASV/L and ATF1500ASV/L devices in the same package variants, offering increased macrocell count (64 vs. 32 or 16), enhanced routing resources, and additional global clock and power management features. Migration requires recompilation with updated fitter software but preserves existing PCB layouts and JTAG infrastructure.
