Overview
The ATF1504AS-7JX44 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports registered operation up to 125 MHz. The device offers a maximum pin-to-pin delay of 7.5 ns and includes In-System Programmability (ISP) via JTAG. It operates on 3.3V or 5.0V I/O supplies and is available in commercial and industrial temperature ranges.
Feature Summary
- 64 Macrocells with expandable logic capacity up to 40 product terms per macrocell
- Maximum pin-to-pin propagation delay of 7.5 ns for high-speed applications
- In-System Programmability (ISP) using the standard 4-pin JTAG interface
- Flexible macrocell architecture supporting D/T/Latch configurable flip-flops
Applications
- Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
- PCI-compliant system designs requiring boundary-scan testing
- High-density digital logic functions with fast registered operation
Procurement Notes
Verify the specific ordering suffix 'JX' against official Microchip documentation to confirm package type and temperature range, as datasheet tables list standard suffixes like 'J' for PLCC packages. Ensure design files include appropriate flags for power-up reset hysteresis if required by the application environment.
Selection Notes
Select this component for designs requiring 64 macrocells and sub-10ns performance. Consider the ATF1504ASL variant if automatic microamp standby power management is needed. Verify that the target PCB layout accommodates the 44-lead package format specified by the suffix.
Part Context
This part belongs to the ATF1504AS(L) family of CPLDs, which utilize Atmel's proven electrically-erasable memory technology. The family provides enhanced routing resources and flexible logic macrocells suitable for complex digital control and interfacing tasks.
Replacement Considerations
Direct replacements within the same speed grade and package are limited due to the specific 'JX' suffix designation. Check for ATF1504AS-7 variants with confirmed compatible packaging such as PLCC-44 or TQFP-44 depending on the exact suffix meaning.
