Overview
The ATF1504AS-7JC68 is a high-performance, high-density Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 logic macrocells with up to 68 inputs and utilizes electrically-erasable memory technology. The device supports In-System Programmability (ISP) via the JTAG interface and offers flexible logic macrocells with configurable flip-flops. Key electrical parameters include a maximum pin-to-pin delay of 7.5 ns, registered operation up to 125 MHz, and support for 3.3V or 5.0V I/O pins. It is available in commercial and industrial temperature ranges.
Feature Summary
- 64 Macrocells with 5 Product Terms per Macrocell, expandable up to 40
- 7.5 ns Maximum Pin-to-Pin Delay and Registered Operation up to 125 MHz
- In-System Programmability (ISP) via JTAG Interface
- Flexible Logic Macrocell with D/T/Latch Configurable Flip-flops
Applications
- High-performance control applications
- Digital design executing boot loader functions
- Loading Field Programmable Gate Array (FPGA) configuration data from non-volatile memory
- Small design applications such as address decoding
Procurement Notes
Verify the specific package type associated with the JC68 suffix against official documentation, as it corresponds to a 68-pin configuration. Confirm that the required operating voltage (3.3V or 5.0V) matches the system design. Ensure that the JTAG boundary-scan testing requirements are met if ISP functionality is utilized in the final application.
Selection Notes
Select this component when a high-density CPLD with fast propagation delays is required. The 64 macrocell count is suitable for integrating logic from several TTL, SSI, MSI, LSI, and classic PLDs. Consider the enhanced routing resources for successful pin-locked design modifications. Verify that the 68-pin package fits the PCB layout constraints.
Part Context
The ATF1504AS belongs to the ATF1504AS/L series of Complex Programmable Logic Devices. This family is characterized by its use of Atmel's proven electrically-erasable memory technology. The series includes various pin counts (44, 68, 84, 100) and speed grades (-7, -10, -15, -20, -25), allowing designers to choose based on performance and packaging needs.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult official Microchip documentation for cross-reference information or compatible alternatives within the same product family.
