ATF1504AS-10JC84

Overview

The ATF1504AS-10JC84 is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell via expandable logic chains. The device supports In-System Programmability (ISP) via the JTAG interface and offers pin-to-pin delays of 10 ns maximum. It operates on 5V or 3.3V I/O supplies and includes advanced power management features such as standby modes and programmable pin-keepers.

Feature Summary

• 64 Macrocells with flexible D/T/Latch flip-flops and up to 40 product terms per macrocell
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• 10 ns maximum pin-to-pin delay with registered operation up to 125 MHz
• Programmable pin-keeper circuits to prevent floating inputs and reduce power consumption

Applications

• High-performance control applications requiring complex combinational or sequential logic
• Digital design tasks involving boot loader execution or configuration data loading for FPGAs
• Address decoding and small-scale logic integration in cost-sensitive portable devices

Procurement Notes

Verify the specific suffix JC84 against official Microchip documentation to confirm the PLCC-84 package and commercial temperature range specifications. Ensure that any ordering suffixes do not alter the functional characteristics unless explicitly stated in the datasheet. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when a non-volatile CPLD with ISP capability is required for designs needing up to 64 macrocells. The 10 ns speed grade suits applications operating below 125 MHz. Consider the PLCC-84 package constraints and verify that the 5V or 3.3V I/O requirements match the system voltage levels.

Part Context

This part belongs to the ATF1504AS/L series of high-performance CPLDs. The 'AS' designation indicates enhanced routing resources and additional features like ITD circuits compared to earlier variants. The 'JC84' suffix specifically identifies the 84-lead PLCC package variant within this family.

Replacement Considerations

Direct replacements within the same family include other ATF1504AS variants with different speed grades or packages, such as ATF1504AS-7JC84 or ATF1504AS-15JC84. Verify pin compatibility and electrical parameters before substitution.
