Product details
Overview
ATF1504ASVL-20AI100 from Microchip Technology is a 3.3V, 100-pin TQFP CPLD with 64 macrocells, 15 ns maximum pin-to-pin delay, 77 MHz registered operation, and automatic 5 µA standby power. It integrates legacy TTL/SSI/MSI logic and supports in-system programming via IEEE 1149.1 JTAG for field-upgradable control logic in industrial PLCs.
For engineers reviewing the ATF1504ASVL-20AI100 datasheet, ATF1504ASVL-20AI100 pinout, ATF1504ASVL-20AI100 application, or ATF1504ASVL-20AI100 equivalent, key selection criteria include its 3.0–3.6V supply range, programmable slew rate per output, dual PD1/PD2 power-down control, JTAG boundary-scan testability, and industrial temperature support (–40°C to +85°C).
Technical Context
The ATF1504ASVL-20AI100 implements a flexible macrocell architecture with five product terms per macrocell-expandable up to 40 via cascade logic-and supports D/T/latch flip-flops with individually configurable clock, reset, and output enable per macrocell. 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 features three dedicated global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks and I/Os, programmable pin-keeper circuits, and VCC power-up reset with selectable hysteresis. The device uses electrically erasable EEPROM for 10,000 program/erase cycles and 20-year data retention, with 2000V ESD protection and 200 mA latch-up immunity.
Key Specifications

Pinout & Package
ATF1504ASVL-20AI100 is housed in a 100-lead thin quad flat pack (TQFP) with 0.5 mm pitch, 14 mm × 14 mm body, and exposed thermal pad. Pin assignments follow Microchip's standard 100-TQFP layout with dedicated global control pins (GCLK1–GCLK3, GCLR, OE1, OE2), dual power-down inputs (PD1/PD2), and four JTAG interface pins (TDI/TMS/TCK/TDO).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 (Pin 87) | Global Clock Input | Primary synchronous clock source for all macrocells; supports fast input path with 2 ns delay and 13.5 ns setup time. |
| GCLR (Pin 89) | Global Clear Input | Asynchronous reset for all registers; can be OR'd with product-term reset for selective clearing. |
| OE1 (Pin 88) | Global Output Enable | Controls tri-state behavior of multiple I/Os; true/complement selectable per macrocell via fitter software. |
| PD1 (Pin 12) | Power-Down Control | Drives device into sub-5 mA power-down mode when high; latches internal states and disables all inputs except PD pins. |
| TCK (Pin 62) | JTAG Clock | Serial programming and boundary-scan clock; 3.3V TTL/CMOS compatible; pull-up option available. |
| VCC (Pins 3,18,34,39,51,66,82,91) | Power Supply | Supplies both core (VCCINT) and I/O (VCCIO) domains; eight distributed pins minimize IR drop and noise coupling. |
| GND (Pins 11,26,38,43,59,74,86,95) | Ground Reference | Eight dedicated ground pins ensure low-impedance return paths for switching currents and reduce ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Configuration | D/T/latch flip-flops with individual clock enable, asynchronous preset/clear, and transparent-latch mode - enables mixed sequential logic styles in same design. |
| Enhanced Routing Resources | Global bus with 68 signals (64 macrocell feedback + I/O), switch matrix selecting up to 40 inputs per logic block - increases successful place-and-route for pin-locked revisions. |
| Programmable Slew Rate | Per-output slow/fast switching selection - reduces EMI and crosstalk on high-speed buses without external termination. |
| Input Transition Detection (ITD) | Edge-sensitive detection on GCLKs, inputs, and I/Os - enables glitch-free asynchronous event capture without external debouncing circuitry. |
| Pin-Keeper Circuits | Programmable keeper on all inputs and I/Os - eliminates need for external pull-ups and prevents floating-induced shoot-through current and noise. |
| VCC Power-Up Reset | Hysteresis-selectable (Small/Large) reset threshold with monotonic VCC requirement - ensures deterministic initialization of state machines at power-on. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASV-20AI100 | Same logic architecture and pinout, but lacks automatic 5 µA standby; uses pin-controlled 100 µA standby instead. | Suitable where lowest quiescent power is not required, and manual standby activation is acceptable. | Select ATF1504ASVL-20AI100 when ultra-low standby power (<5 µA) is mandatory for battery-backed or energy-harvesting systems. |
| XC95144XL-10TQ100C | Xilinx CoolRunner-II device; 144 macrocells, 10 ns speed grade, 3.3V operation; no built-in ITD or pin-keeper circuits. | Better suited for larger logic density needs, but requires external components for input conditioning and power management. | Choose ATF1504ASVL-20AI100 when integrated ITD, pin-keeper, and automatic standby simplify BOM and improve system-level reliability. |
Compared with ATF1504ASV-20AI100, the ATF1504ASVL-20AI100 delivers 20× lower standby current without external control; versus XC95144XL-10TQ100C, it trades macrocell count for integrated analog-friendly features like ITD and pin-keepers-reducing component count and layout risk in industrial control designs.

FAQ
What is the operating voltage range for the ATF1504ASVL-20AI100?
The ATF1504ASVL-20AI100 operates from 3.0V to 3.6V on both VCCIO and VCCINT rails. This 3.3V nominal range ensures compatibility with modern low-voltage digital systems while maintaining noise margin and signal integrity. The device is not rated for 5V operation, and applying voltages outside this range may cause permanent damage per Absolute Maximum Ratings.
Does the ATF1504ASVL-20AI100 support in-system programming (ISP)?
Yes, the ATF1504ASVL-20AI100 supports full IEEE 1149.1 JTAG-based in-system programming via its TDI, TMS, TCK, and TDO pins. ISP allows configuration without removing the device from the PCB, enabling manufacturing flexibility and field firmware updates. The JTAG interface is always active unless disabled in the design file to reclaim those pins as general-purpose I/O.
How many I/O pins does the ATF1504ASVL-20AI100 provide in its 100-TQFP package?
The ATF1504ASVL-20AI100 in the 100-lead TQFP package provides 64 user-configurable I/O pins plus four dedicated input pins (GCLK1, GCLR, OE1, GCLK2), totaling 68 signal-capable pins. Eight pins are reserved for GND and eight for VCC, leaving no unused or NC pins beyond those explicitly listed in Table 1-6 of the datasheet.
What is the purpose of the PD1 and PD2 pins on the ATF1504ASVL-20AI100?
The PD1 and PD2 pins on the ATF1504ASVL-20AI100 serve as hardware-controlled power-down inputs. When either pin is driven high (with power-down mode enabled in the design), the device enters a sub-5 mA low-power state while latching all internal logic and output states. These pins cannot function as logic I/O when power-down is active, but their associated macrocell resources remain usable for foldback and cascade logic.
Is the ATF1504ASVL-20AI100 RoHS compliant and halogen-free?
Yes, the ATF1504ASVL-20AI100 is Green (Pb/Halide-Free/RoHS Compliant) per Microchip's documentation. It meets EU RoHS Directive 2011/65/EU and JEDEC JS709B requirements for bromine and chlorine content, with no intentionally added halogens. Full compliance documentation, including material declarations and test reports, is available through Microchip's quality portal.
