Product details
Overview
ATF1504ASVL-20JI44 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) in 44-pin PLCC package, featuring 15 ns maximum pin-to-pin delay, 77 MHz registered operation, and automatic 5 µA standby current. It supports in-system programming via JTAG, includes three global clock inputs, and targets logic consolidation in industrial control, legacy interface bridging, and power-sensitive embedded systems.
For engineers reviewing the ATF1504ASVL-20JI44 datasheet, ATF1504ASVL-20JI44 pinout, ATF1504ASVL-20JI44 application, or ATF1504ASVL-20JI44 equivalent, key selection criteria include its 3.0–3.6V supply range, JTAG boundary-scan compliance (IEEE 1149.1a), PCI-compatibility, programmable slew rate per output, and dual PD1/PD2 pin-controlled power-down capability.
Technical Context
The ATF1504ASVL-20JI44 implements a macrocell-based architecture with five product terms per macrocell-expandable to 40 via cascade logic-and flexible flip-flop configuration (D/T/latch). Its global bus feeds all 64 macrocells and I/O pins, enabling high-utilization routing with up to 40 signals selected per logic block.
It integrates IEEE 1149.1a-compliant JTAG boundary-scan cells on all I/O and input pins, supports VCC power-up reset with selectable hysteresis, and features ITD (Input Transition Detection) circuits on global clocks, inputs, and I/Os for glitch detection and low-power wake-up triggering.

Pinout & Package
ATF1504ASVL-20JI44 is packaged in a 44-lead PLCC (Plastic Leaded Chip Carrier) with 0.05-inch lead pitch, surface-mount compatible, and RoHS-compliant. The package provides 32 user I/O pins plus dedicated control pins including GCLK1–GCLK3, GCLR, OE1/OE2, PD1/PD2, and full JTAG interface (TCK/TMS/TDI/TDO).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TDI/I/O) | JTAG Test Data Input / General I/O | Primary serial input for ISP programming and boundary-scan data loading; configurable as logic I/O when JTAG disabled |

| 26 (I/O/TCK) | JTAG Test Clock / General I/O | Drives synchronous JTAG state transitions; usable as clock input or general-purpose I/O |
| 32 (I/O/TDO) | JTAG Test Data Output / General I/O | Serial output for boundary-scan register readback; bidirectional I/O when JTAG inactive |
| 37 (INPUT/GCLK1) | Global Clock Input 1 | Dedicated low-skew clock source for synchronous logic across all macrocells |
| 38 (INPUT/OE1) | Global Output Enable 1 | Active-low signal controlling output drivers of multiple macrocells simultaneously |
| 39 (INPUT/GCLR) | Global Clear Input | Asynchronous reset for all macrocell flip-flops; critical for state machine initialization |
| 40 (INPUT/OE2/GCLK2) | Global Output Enable 2 / Global Clock 2 | Multiplexed pin supporting either second global OE or secondary clock domain |
| 35 (I/O/GCLK3) | Global Clock Input 3 / I/O | Third global clock input with fallback to bidirectional I/O function |
| 5, 19 (I/O/PD1, I/O/PD2) | Power-Down Control Inputs | High-active signals entering low-power mode; disable logic activity while preserving output states |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-output switching speed control reduces EMI and allows optimization for timing vs. noise trade-offs |
| Pin-Keeper Circuits | Prevents floating inputs/I/Os without external pull-ups, eliminating DC leakage and system noise |
| Reduced-Power Macrocell Bit | Individually disables unused macrocell resources to cut dynamic power consumption |
| Transparent-Latch Mode | Enables flow-through latch behavior (data passes when clock high, latches when low) for asynchronous control paths |
| VCC Power-Up Reset | Hardware-initiated register initialization at power-on; configurable hysteresis ensures robust startup in 3.0V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-15JU44 | Same 44-pin PLCC package but –15 speed grade (12.5 ns tPD); no automatic standby (75 mA ICC1) | Better timing margin for high-speed control loops; unsuitable for ultra-low-power sleep modes | Select when maximum speed is required and standby current is not constrained |
| XC9536XL-10VQ44C | Xilinx CoolRunner-II family; 36 macrocells; 3.3V; 10 ns tPD; 10 µA standby; different JTAG BSDL | Lower density but lower static power; requires Xilinx toolchain; no ITD or pin-keeper circuits | Choose for cost-sensitive, low-density designs where Microchip toolchain independence is preferred |

FAQ
What is the standby current specification for ATF1504ASVL-20JI44?
The ATF1504ASVL-20JI44 features automatic 5 µA typical standby current (ICC1) when no logic transitions occur - a key differentiator from the non-L variant (ATF1504ASV), which draws 75 mA in standby. This ultra-low quiescent current is achieved through internal transition detection circuitry and is verified per DS20006185A-page 8, Table 1-2.
Does ATF1504ASVL-20JI44 support in-system programming?
Yes, ATF1504ASVL-20JI44 supports full in-system programming (ISP) via the standard 4-pin JTAG interface (TCK/TMS/TDI/TDO) compliant with IEEE Std. 1149.1a-1993. Programming can be performed without removing the device from the PCB using Microchip's ProChip Designer or third-party tools that support SVF files.
What package type does ATF1504ASVL-20JI44 use?
ATF1504ASVL-20JI44 uses a 44-lead PLCC (Plastic Leaded Chip Carrier) package with J-bend leads, designated by the "J" in the suffix. Pin 1 is marked by a notch on the package body, and the top-view pinout matches DS20006185A-page 3 diagram for 44-Lead PLCC.
How many global clock inputs does ATF1504ASVL-20JI44 provide?
ATF1504ASVL-20JI44 provides three dedicated global clock inputs: GCLK1 (pin 37), GCLK2/OE2 (pin 40), and GCLK3/I/O (pin 35). These pins drive low-skew clock distribution networks across all 64 macrocells and support independent clock domains for multi-rate logic design.
Can the PD1 and PD2 pins on ATF1504ASVL-20JI44 be used as general-purpose I/O?
No - when the power-down feature is enabled in the design file, PD1 (pins 5 and 19) and PD2 become dedicated control inputs and cannot serve as logic I/O. However, their associated macrocells retain buried feedback and foldback logic capabilities, allowing internal signal routing even while the pins are reserved for power management.
