Overview
The ATF1504AS-10JU84 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 84 I/O pins in an 84-lead PLCC 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 non-volatile configuration, allowing 10,000 program/erase cycles and 20-year data retention. The component supports both 3.3V and 5.0V I/O levels and includes In-System Programmability (ISP) via JTAG.
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
- EEPROM-based non-volatile memory with 10,000 program/erase cycles
- Supports 3.3V or 5.0V I/O pins with programmable slew rates
Applications
- High-density logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
- PCI-compliant interface designs requiring high current drivers
- Complex state machine initialization and control applications
- Digital design applications requiring field modifications via software
Procurement Notes
Verify the specific suffix 'JU84' against official Microchip documentation to confirm the exact package type (84-lead PLCC), temperature range (Commercial or Industrial), and speed grade. Ensure that any ordering suffixes do not alter the functional specifications unless explicitly stated in the manufacturer's datasheet.
Selection Notes
Select this component when a high-density CPLD with 64 macrocells and 84 pins is required. Consider the 10 ns delay specification for timing-critical paths. Verify compatibility with 3.3V or 5.0V supply voltages and ensure the design supports JTAG-based programming if ISP functionality is needed.
Part Context
This part belongs to the ATF1504AS/L series of high-performance CPLDs from Microchip Technology. The series offers various pin counts (44, 68, 84, 100) and packages (PLCC, TQFP, PQFP). The 'AS' variant typically denotes standard performance characteristics within this family.
Replacement Considerations
Consult Microchip's official cross-reference tools or datasheets for verified replacement part numbers. Ensure any substitute maintains the same macrocell count, pinout, and voltage requirements.
