Overview
The ATF1504AS-7AX100 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 68 inputs and supports 100-pin packages including PQFP and TQFP. The device offers a maximum pin-to-pin delay of 7.5 ns and registered operation frequencies up to 125 MHz. It utilizes EEPROM technology for complete reprogrammability, supporting In-System Programmability (ISP) via JTAG. The component operates at 3.3V or 5.0V I/O levels and includes advanced power management features such as standby modes and programmable pin-keeper circuits.
Feature Summary
- 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
- Maximum 7.5 ns pin-to-pin propagation delay
- In-System Programmability (ISP) via IEEE 1149.1 JTAG interface
- Supports 3.3V and 5.0V I/O voltage levels
Applications
- PCI-compliant interface designs
- Complex logic integration replacing TTL/SSI/MSI/LSI components
- High-speed digital signal processing requiring registered operations up to 125 MHz
Procurement Notes
Verify the specific ordering suffix 'X' against official Microchip documentation to confirm package type and temperature range, as standard datasheets list PQFP and TQFP options. Confirm RoHS compliance status and current availability through authorized distributors, as older CPLD series may have limited stock or end-of-life status.
Selection Notes
Select this model for applications requiring high density in a 100-pin package with fast switching speeds. Ensure the design compiler supports the ATF1504AS architecture for optimal routing. Consider the 'L' variant if ultra-low standby current is required, or verify if the standard AS version meets power constraints. Check pin compatibility if migrating from previous PLD generations.
Part Context
This part belongs to the ATF1504AS/L family of high-density CPLDs. It shares architectural similarities with other members like the ATF1504AS-10AU100 but offers faster timing specifications. The family is characterized by its enhanced routing resources and flexible macrocell structure, designed to integrate classic PLD functionality with modern ISP capabilities.
Replacement Considerations
Direct replacements within the same family include ATF1504AS-10AU100 (slower speed) or ATF1504AS-15AC44 (different package). Verify pinout compatibility when substituting with different package types such as PLCC or TQFP variants.
