ATF1500A-12JC

Overview

The ATF1500A-12JC is a high-performance, high-density Electrically Erasable Complex Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 32 logic macrocells and up to 36 inputs within a 44-pin Plastic J-leaded Chip Carrier (PLCC) package. The device utilizes advanced Flash technology, allowing for complete reprogrammability with 100 program/erase cycles and 20-year data retention. Key electrical parameters include a maximum pin-to-pin delay of 7.5 ns, registered operation speeds up to 125 MHz, and a 5V power supply requirement. It supports both commercial and industrial temperature ranges.

Feature Summary

• High-density architecture with 32 macrocells and fully connected input/feedback logic array
• Advanced Flash technology enabling 100% testing, full reprogrammability, and 20-year data retention
• Flexible macrocell design supporting D/T/Latch configurable flip-flops and programmable output slew rates
• Built-in speed and power management including automatic standby mode and pin-controlled power-down

Applications

• Integration of TTL, SSI, MSI, and classic PLD logic functions
• State machine initialization and control applications
• Complex combinatorial and sequential logic implementations
• System noise reduction through programmable output slew rate control

Procurement Notes

Verify the specific ordering suffix 'JC' corresponds to the 44-lead PLCC package and commercial temperature range (0°C to 70°C). Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure compatibility with existing programming tools and JEDEC file formats for design implementation.

Selection Notes

Select the ATF1500A-12JC when a maximum propagation delay of 12 ns and clock-to-output delay of 6 ns are required. This part offers backward compatibility with ATF1500/L software and hardware. Consider the ATF1502AS as a pin-compatible replacement for faster speed grades if higher performance is needed in future designs.

Part Context

The ATF1500A series belongs to Microchip's family of high-performance EEPLDs built on Flash technology. It provides a flexible alternative to traditional EPROM-based PLDs by eliminating the need for UV erasure. The device is designed to simplify logic placement through its global bus architecture, preventing pinout changes during design modifications.

Replacement Considerations

The ATF1502AS is identified as a pin-compatible replacement for fast-speed grade devices. For other speed grades, suggested replacements are available in Green packages. Verify specific pin compatibility and electrical characteristics before substituting.
