Overview
The ATF1504AS-10JC68 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 I/O pins in a 68-pin PLCC package. The device supports In-System Programmability (ISP) via JTAG and offers a maximum pin-to-pin delay of 10 ns. It operates on 3.3V or 5.0V I/O supplies and includes advanced power management features such as standby modes and reduced-power options per macrocell.
Feature Summary
- 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
- In-System Programmability (ISP) using IEEE Std. 1149.1 JTAG interface
- Maximum propagation delay of 10 ns with registered operation up to 100 MHz
- Supports both 3.3V and 5.0V I/O voltage levels
Applications
- Complex logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
- PCI-compliant interface designs requiring high current drivers
- Systems requiring in-field design modifications via software programming
Procurement Notes
Verify the specific ordering suffix 'JC' corresponds to the 68-pin PLCC package and commercial temperature range (0°C to 70°C). Confirm that the '-10' speed grade matches the required 10 ns maximum delay specification for the target application timing constraints.
Selection Notes
Select this component when 64 macrocells are sufficient for the logic density requirements. Ensure the design utilizes the JTAG interface for ISP if field updates are needed. Consider the 68-pin PLCC footprint during PCB layout. Verify power supply compatibility with either 3.3V or 5.0V I/O standards.
Part Context
This part belongs to the ATF1504AS/L series of CPLDs. It shares architectural similarities with other variants in the family, differing primarily in package type (68-pin PLCC), speed grade (-10), and operating temperature range (Commercial). It is designed for applications needing reprogrammable logic with low standby power.
Replacement Considerations
Direct replacements within the same package and speed grade include ATF1504AS-10JU68. Other speed grades like ATF1504AS-7JC68 offer faster performance, while ATF1504AS-15JC68 offers lower cost with slower speeds. Package variations include 44-pin PLCC/TQFP and 84/100-pin options.
