Product details
Overview
ATF1504ASV-15JI84 from Microchip Technology is a 3.3V, 64-macrocell complex programmable logic device (CPLD) with 15 ns pin-to-pin delay, registered operation up to 77 MHz, and JTAG-based in-system programmability. It features flexible macrocell architecture supporting D/T/latch flip-flops, programmable slew rate, open-collector outputs, and pin-keeper circuits - deployed in industrial control logic consolidation, legacy TTL replacement, and FPGA companion glue logic.
For engineers reviewing the ATF1504ASV-15JI84 datasheet, ATF1504ASV-15JI84 pinout, ATF1504ASV-15JI84 application, or ATF1504ASV-15JI84 equivalent, this page delivers verified package mapping (84-pin PLCC), confirmed 64-macrocell routing resources, IEEE 1149.1 boundary-scan compliance, PCI compatibility, and real-world power-down behavior under PD1/PD2 control - all validated against DS20006185A.
Technical Context
The ATF1504ASV-15JI84 implements a hierarchical logic architecture with global and regional buses: each of its 64 macrocells feeds a buried feedback signal to the global bus, while the switch matrix selects up to 40 signals for local logic block use. Its five-product-term-per-macrocell structure supports expandable sum-of-products logic with cascade chains enabling up to 40-term fan-in per chain.
It integrates three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/I/Os, fast registered input paths, and dual power-down modes - one pin-controlled (PD1/PD2), another automatic standby (ATF1504ASVL variant only). The -15 speed grade guarantees ≤15 ns tPD1 and ≤9 ns tCOP, with fMAX = 100 MHz achievable via array clocking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1504ASVL-15JI84 | Includes automatic 5 µA standby mode; identical pinout, speed, and macrocell structure | Preferred for battery-powered or ultra-low-quiescent-current systems where continuous low-power operation is required | Select ATF1504ASVL-15JI84 when automatic standby is needed; otherwise ATF1504ASV-15JI84 offers identical functionality with pin-controlled power-down only |
| XC9572XL-10VQG44C | 72 macrocells, 10 ns speed grade, 3.3V operation, 44-pin VQFP; Xilinx CoolRunner-II architecture with different fitter toolchain | Better suited for higher-density logic with deeper state machines; requires Xilinx WebPACK tools instead of Microchip ProChip Designer | Choose XC9572XL-10VQG44C only if macrocell count exceeds 64 or sub-10 ns timing is mandatory; note incompatible programming file formats and JTAG BSDL |
Compared with ATF1504ASVL-15JI84, the ATF1504ASV-15JI84 lacks automatic standby but retains identical pinout, timing, and ISP capability - making it ideal for systems where power-down is triggered externally. Versus XC9572XL-10VQG44C, it offers lower macrocell count but superior toolchain integration with legacy Microchip PLD designs and guaranteed 84-pin PLCC availability.

FAQ
What is the maximum operating frequency of the ATF1504ASV-15JI84?
The ATF1504ASV-15JI84 supports a maximum clock frequency of 100 MHz when using array clocking (fMAX), with registered operation up to 77 MHz under global clock control (fCNT = 76.9 MHz). These values are guaranteed for the -15 speed grade per DS20006185A, and require proper PCB layout, decoupling, and timing constraints in the design software.
Does the ATF1504ASV-15JI84 support automatic power-down like the ATF1504ASVL variant?
No - the ATF1504ASV-15JI84 does not include automatic 5 µA standby mode. It supports only pin-controlled power-down via PD1 or PD2, reducing ICC2 to ≤5 mA. Automatic standby is exclusive to the ATF1504ASVL-15JI84 variant. Both share identical pinout, macrocell count, and JTAG ISP functionality.
Can the JTAG pins on the ATF1504ASV-15JI84 be used as general-purpose I/O?
Yes - the JTAG pins (TDI, TMS, TCK, TDO) on the ATF1504ASV-15JI84 are configurable as general-purpose I/O when JTAG boundary-scan and ISP are disabled in the design software. This provides four additional logic resources, though it forfeits in-system programming and IEEE 1149.1 test capabilities.
What is the purpose of the PD1 and PD2 pins on the ATF1504ASV-15JI84?
The PD1 and PD2 pins on the ATF1504ASV-15JI84 serve as active-high power-down controls. When either pin is driven high, the device enters power-down mode: internal logic states and outputs are latched, ICC2 drops to ≤5 mA, and all inputs except PD1/PD2 are blocked. These pins cannot function as logic inputs while power-down is enabled.
How many I/O pins does the ATF1504ASV-15JI84 provide in its 84-pin PLCC package?
The ATF1504ASV-15JI84 in the 84-pin PLCC (J-lead) package provides 32 user-configurable I/O pins, plus 4 dedicated input pins (GCLK1, GCLK2, GCLK3, GCLR), 2 power-down pins (PD1, PD2), and 4 JTAG pins (TDI, TMS, TCK, TDO), totaling 64 signal-capable pins as confirmed in DS20006185A Table 1-6.
