Product details
Overview
ATF1504ASVL-20JC68 from Microchip Technology is a 3.3V, 64-macrocell Complex Programmable Logic Device (CPLD) with 100-pin TQFP packaging, 15 ns pin-to-pin delay, registered operation up to 77 MHz, and automatic 5 µA standby current. It integrates logic from TTL, SSI, MSI, LSI, and classic PLDs in industrial control, legacy interface bridging, and FPGA configuration management systems.
For engineers reviewing the ATF1504ASVL-20JC68 datasheet, ATF1504ASVL-20JC68 pinout, ATF1504ASVL-20JC68 application, or ATF1504ASVL-20JC68 equivalent, key selection criteria include JTAG ISP support, 3.0–3.6V supply range, programmable slew rate per output, dual power-down pins (PD1/PD2), and IEEE 1149.1 boundary-scan compliance for production testability.
Technical Context
The ATF1504ASVL-20JC68 implements a macrocell architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports combinatorial or registered outputs with buried feedback routing. Its global bus feeds all 64 macrocells and I/Os, enabling flexible signal routing across four logic chains.
It features three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, fast registered input paths, and programmable pin-keeper circuits. Power management includes automatic standby mode, per-macrocell reduced-power bit, and edge-controlled power-down triggered by PD1 or PD2 pins.
Key Specifications

|---|---|
| Logic Density | 64 macrocells - provides gate count equivalent to ~1500 usable gates for medium-complexity glue logic. |
| Timing Performance | 15 ns max pin-to-pin delay (–20 speed grade) - enables reliable operation at 66 MHz system clock rates. |
| Supply Voltage | 3.0 V to 3.6 V - compatible with 3.3V TTL/CMOS interfaces and avoids level-shifting in mixed-voltage boards. |
| Standby Current | 5 µA typical (ATF1504ASVL variant) - reduces quiescent power in battery-backed or always-on industrial modules. |
| Package | 100-lead TQFP (14 × 14 mm, 0.5 mm pitch) - surface-mount compatible with standard reflow profiles and AOI inspection. |

| I/O Count | 64 user I/O pins + 4 dedicated inputs - supports high-pin-count legacy bus interfacing (e.g., ISA, PCI, parallel ATA). |
Pinout & Package
ATF1504ASVL-20JC68 is housed in a 100-lead Thin Quad Flat Package (TQFP) with exposed pad, 0.5 mm lead pitch, and RoHS-compliant Pb/Halide-free finish. Pin 1 is marked by a dot; pin numbering proceeds counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 12, 42 | PD1 / PD2 | Power-down control inputs - drive high to enter sub-5 mA power-down mode; latches internal state and holds outputs. |
| 87–90, 85 | GCLK1 / GCLK2 / OE1 / OE2 / GCLK3 | Dedicated global clock and output-enable inputs - provide low-skew timing control and synchronized I/O gating. |
| 89 | GCLR | Global asynchronous clear - resets all registers simultaneously, supporting deterministic state-machine initialization. |
| 3–11, 13–24, 26–31, 33–41, 43–50, 52–61, 63–72, 74–84, 91–100 | I/O | Bidirectional logic pins - configurable as input, output, or tristate; each supports programmable slew rate and pin-keeper. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20JC68 | Higher standby current (75 mA vs. 5 µA); no automatic low-power mode. | Suitable only where continuous active operation is guaranteed and power budget allows >10× higher quiescent draw. | Select only if automatic standby is unnecessary and legacy design uses non-L variant. |
| XC9572XL-10TQ100C | 72 macrocells, 10 ns tPD, 3.3V core, but no integrated pin-keeper or ITD circuits. | Lacks built-in input transition detection and requires external pull-ups for unused I/Os. | Prefer when maximum speed (100 MHz fMAX) is critical and power management features are handled externally. |
Compared with ATF1504ASVL-20JC68, the ATF1504ASV-20JC68 trades ultra-low standby for identical logic density and routing, while the XC9572XL-10TQ100C offers faster timing at the cost of missing integrated power-saving and noise-reduction features essential for embedded industrial use.

FAQ
What is the operating voltage range for ATF1504ASVL-20JC68?
The ATF1504ASVL-20JC68 operates over a 3.0 V to 3.6 V supply range, meeting 3.3V TTL and CMOS interface standards. This range ensures compatibility with common industrial power rails and avoids level-shifting circuitry. The device's DC characteristics-including VIH, VOL, and VOH-are fully specified across this range, and its automatic standby mode remains functional at the minimum 3.0V rail. ATF1504ASVL-20JC68 must not be operated outside these limits to maintain EEPROM data retention and timing compliance.
How does the automatic standby mode function in ATF1504ASVL-20JC68?
The ATF1504ASVL-20JC68 enters automatic 5 µA standby when no logic transitions occur-reducing power proportionally below 5 MHz system activity. This feature is intrinsic to the "L" suffix variant and requires no external control. Unlike manual power-down modes triggered by PD1/PD2, automatic standby responds dynamically to internal signal activity and resumes full operation immediately upon next transition. ATF1504ASVL-20JC68 maintains all register states and output levels during this mode, ensuring seamless resumption of real-time control tasks.
Can ATF1504ASVL-20JC68 be programmed in-system without removing it from the board?
Yes, ATF1504ASVL-20JC68 supports full in-system programming (ISP) via its 4-pin JTAG interface (TCK, TMS, TDI, TDO), compliant with IEEE Std. 1149.1. Programming can be performed using Microchip's ProChip Designer or third-party tools generating SVF files. The JTAG port remains accessible even when other pins are configured as logic I/Os, and boundary-scan testing is supported concurrently. ATF1504ASVL-20JC68 ships erased and ready for ISP, eliminating pre-programming steps in manufacturing.
What package type and pin count does ATF1504ASVL-20JC68 use?
ATF1504ASVL-20JC68 uses a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, 14 mm × 14 mm body size, and exposed thermal pad. It provides 64 user I/O pins plus 4 dedicated inputs (GCLK1, GCLK2, GCLK3, GCLR), two power-down pins (PD1, PD2), and full JTAG connectivity. This package is compatible with standard SMT assembly processes and supports automated optical inspection. ATF1504ASVL-20JC68 is not offered in PLCC or 44-pin variants-the "JC68" suffix explicitly denotes the 100-lead TQFP.
Does ATF1504ASVL-20JC68 support security protection of programmed logic?
Yes, ATF1504ASVL-20JC68 includes a one-time programmable security fuse that disables readback of fuse pattern contents once set. While the 16-bit User Signature remains readable regardless of fuse state, the actual logic configuration cannot be extracted after fuse programming. This protects intellectual property in deployed systems. ATF1504ASVL-20JC68 also supports JTAG lockout-disabling the TAP controller entirely-when JTAG functionality is not required, freeing all four JTAG pins for general-purpose I/O use.
