ATF1500A-12JI

Overview

The ATF1500A-12JI is a high-performance, electrically-erasable complex programmable logic device (CPLD) manufactured by Atmel. It features 32 logic macrocells and supports up to 36 inputs in a 44-pin package. The device utilizes advanced Flash technology for reprogrammability and offers a maximum pin-to-pin delay of 7.5 ns with registered operation speeds up to 125 MHz. It includes flexible macrocell configurations, global/regional busses, and power management features such as automatic standby and pin-controlled power-down modes.

Feature Summary

• High-density architecture with 32 macrocells and fully connected input/feedback logic array
• Maximum pin-to-pin delay of 7.5 ns and registered operation up to 125 MHz
• Flexible macrocell supporting D/T/Latch configurable flip-flops and individual register control
• Advanced Flash technology with 100 program/erase cycles and 20-year data retention

Applications

• Integration of TTL, SSI, MSI, and classic PLD logic functions
• State machine initialization and sequential logic design
• Complex combinatorial and registered logic implementation
• System noise reduction via programmable output slew rate control

Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Atmel Corporation before its acquisition by Microchip Technology. Confirm the specific speed grade (-12) and industrial temperature range (-40°C to +85°C) required for the application. Ensure that the 44-lead PLCC or TQFP package option matches the PCB footprint design constraints.

Selection Notes

Select the ATF1500A-12JI for designs requiring 32 macrocells with a 7.5 ns maximum delay. Choose this part over the ATF1500AL variant if higher active current is acceptable for faster performance. Consider the -10AC/-10AI or -15AC/-15AI variants if different speed/power trade-offs are needed. Verify compatibility with existing third-party design tools and fitters.

Part Context

This component belongs to the ATF1500A series of high-performance CPLDs. It is backward compatible with the earlier ATF1500/L software and hardware. The device is available in commercial and industrial temperature ranges and comes in 44-lead PLCC and TQFP packages. It serves as a drop-in replacement for many legacy PLD applications.

Replacement Considerations

For the fast-speed grade, the ATF1502AS is a pin-compatible replacement. Other suggested replacements are available in Green packages. Consult the ordering information section for specific cross-reference details based on speed and temperature requirements.
