Overview
The ATF1504AS-10AU100 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports 100 pins in a TQFP package. The device operates at a maximum pin-to-pin delay of 10 ns and supports registered operation up to 125 MHz. It utilizes EEPROM technology for reprogramming, offers In-System Programmability (ISP) via JTAG, and supports both 3.3V and 5.0V I/O levels.
Feature Summary
- 64 Macrocells with expandable logic capacity up to 40 product terms per macrocell
- In-System Programmability (ISP) via standard 4-pin JTAG interface
- Maximum propagation delay of 10 ns with registered operation up to 125 MHz
- Supports 3.3V or 5.0V I/O pins with programmable slew rates
Applications
- Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
- PCI-compliant interface designs requiring high current drivers
- Boundary-scan testing and system debugging via IEEE Std. 1149.1
Procurement Notes
Verify the specific suffix 'AU100' corresponds to the 100-lead TQFP package and commercial temperature range during sourcing. Confirm that the component matches the ATF1504AS series specifications rather than the ATF1504ASL low-power variant. Ensure compatibility with design tools supporting the ISP protocol.
Selection Notes
Select this model for applications requiring 100 I/O pins and a 10 ns speed grade. Choose the ATF1504AS over the ASL version if automatic microamp standby power management is not required. Verify that the 100-lead TQFP footprint fits the PCB layout constraints. Consider the 10,000 program/erase cycle endurance for field update requirements.
Part Context
This component belongs to the ATF1504AS/L family of CPLDs from Microchip Technology. The 'AS' designation indicates standard performance characteristics, while the 'L' suffix denotes low-power variants with automatic standby modes. The ATF1504AS provides enhanced routing resources and flexible macrocell configurations compared to earlier generations.
Replacement Considerations
Direct replacements within the same package include other ATF1504AS variants with different speed grades (e.g., -7, -15, -20). Cross-family upgrades may involve ATF1508AS or ATF2500C models for increased macrocell counts, though pin compatibility must be verified.
