Product details
Overview
ATF1504ASV-15AU100 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, registered operation up to 77 MHz, and in-system programmability via IEEE 1149.1 JTAG interface. It integrates legacy TTL/SSI/MSI logic and replaces classic PLDs in industrial control and board-level glue logic.
For engineers reviewing the ATF1504ASV-15AU100 datasheet, ATF1504ASV-15AU100 pinout, ATF1504ASV-15AU100 application, or ATF1504ASV-15AU100 equivalent, key selection criteria include macrocell count (64), global clock support (3 pins), power-down capability (PD1/PD2), JTAG boundary-scan compliance, and industrial temperature range (-40°C to +85°C).
Technical Context
The ATF1504ASV-15AU100 implements a flexible macrocell architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports D/T/latch flip-flops, combinatorial outputs with registered feedback, and transparent-latch mode. Its global bus feeds all 64 macrocells and I/Os, enabling high-utilization routing.
It features three dedicated global clock inputs (GCLK1–GCLK3), input transition detection (ITD) circuits on clocks and I/Os, fast registered input from product terms, and programmable pin-keeper circuits for floating-input immunity. Power management includes pin-controlled standby (100 µA typical) and per-macrocell reduced-power mode.

Pinout & Package
ATF1504ASV-15AU100 is housed in a 100-lead thin quad flat pack (TQFP) with 0.5 mm pitch, 14 mm × 14 mm body size, and exposed thermal pad (per Microchip DS20006185A, page 3). The package delivers 64 user I/O pins, four dedicated input pins (GCLK1, GCLK2/OE2, GCLR, OE1), two power-down pins (PD1, PD2), four JTAG pins (TDI, TMS, TCK, TDO), eight VCC (VCCIO/VCCINT), and eight GND terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1 / INPUT | Global Clock Input 1 | Primary clock source for synchronous logic; drives all macrocells when selected as array clock |
| GCLK2 / OE2 / INPUT | Global Clock Input 2 or Output Enable 2 | Dual-function pin: configurable as second global clock or global output enable for grouped I/Os |
| GCLK3 / I/O | Global Clock Input 3 or Bidirectional I/O | Third clock domain support or general-purpose I/O; enables multi-clock domain designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15AU100 | Includes automatic 5 µA standby mode (vs. pin-controlled 100 µA in ATF1504ASV); identical pinout, macrocell count, and AC specs | Better suited for battery-powered or ultra-low-quiescent systems where continuous low-power operation is required | Select ATF1504ASVL-15AU100 only if automatic standby is mandatory; otherwise ATF1504ASV-15AU100 offers greater control over power-state transitions |
| XCR3064XL-10VQ100C | 64-macrocell CoolRunner-II CPLD; 10 ns tPD, 125 MHz fMAX, 2.7V–3.6V supply; no EEPROM - requires external configuration PROM | Higher speed and lower static current, but lacks in-field reprogrammability and requires boot-time configuration | Choose XCR3064XL-10VQ100C for performance-critical, high-volume production where configuration persistence isn't required; retain ATF1504ASV-15AU100 for field-upgradable or low-NRE prototyping |
Compared with ATF1504ASVL-15AU100, the ATF1504ASV-15AU100 trades automatic low-power entry for precise pin-triggered control - critical in systems requiring deterministic wake-up latency. Against XCR3064XL-10VQ100C, it prioritizes EEPROM-based instant-on configurability and JTAG ISP over raw speed, making it superior for maintenance-sensitive industrial deployments.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15AU100?
The ATF1504ASV-15AU100 supports registered operation up to 77 MHz, with a minimum global clock period of 13 ns (–15 speed grade). Its maximum internal array clock frequency is 76.9 MHz, and the device achieves 100 MHz maximum clock frequency under specific conditions. These values are confirmed in Table 1-4 of the official datasheet DS20006185A.
Does the ATF1504ASV-15AU100 support in-system programming (ISP)?
Yes, the ATF1504ASV-15AU100 supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TDI, TMS, TCK, TDO). ISP allows full configuration and reprogramming without removing the device from the PCB, and the JTAG port can be disabled to reclaim those pins as general-purpose I/O if needed.
What is the difference between ATF1504ASV-15AU100 and ATF1504ASVL-15AU100?
The ATF1504ASVL-15AU100 adds automatic 5 µA standby mode triggered by inactivity, whereas the ATF1504ASV-15AU100 uses pin-controlled 100 µA standby. Both share identical pinout, macrocell count, timing specs, and EEPROM technology. The "L" suffix denotes enhanced power management, not a different package or logic architecture.
How many I/O pins does the ATF1504ASV-15AU100 provide in its 100-lead TQFP package?
The ATF1504ASV-15AU100 in 100-lead TQFP provides 64 user I/O pins, as documented in Table 1-6 of DS20006185A. This includes bidirectional I/Os and dedicated pins repurposed as global clocks (GCLK1–GCLK3), output enables (OE1/OE2), global clear (GCLR), and power-down controls (PD1/PD2).
Is the ATF1504ASV-15AU100 RoHS compliant and lead-free?
Yes, the ATF1504ASV-15AU100 is green (Pb/Halide-Free/RoHS Compliant), as explicitly stated in the "Features" section of DS20006185A. It meets EU RoHS Directive 2011/65/EU and related halogen-free material requirements for industrial electronics.
