ATF750LVC-15JU

Complex Programmable Logic Devices Overview

The ATF750LVC-15JU is a high-performance CMOS electrically-erasable complex programmable logic device (CPLD) from the Atmel 750 architecture. It operates within a 3.0V to 5.5V supply range and features 22 logic pins, including 10 I/Os. The device provides 42 array inputs, 20 sum terms, and 20 individually configurable D- or T-type flip-flops. It delivers a maximum pin-to-pin delay of 15 ns at 3V operation and supports up to 1000 erase/write cycles with 20-year data retention. Packaged in a 28-lead PLCC, it includes programmable pin-keeper circuits and meets industrial temperature standards.

Complex Programmable Logic Devices Feature Summary

• High-density logic in a 24-pin equivalent footprint: 42 inputs, 20 sum terms, and 20 flip-flops.
• Flexible clocking: Individual product term clocks or direct input pin clocking for each flip-flop.
• Configurable registers: Each flip-flop can be set as D-type or T-type; asynchronous reset and synchronous preset available.
• Bus-friendly design: Programmable pin-keeper circuits prevent floating inputs without external resistors.

Complex Programmable Logic Devices Applications

• Complex state machine implementation
• High-speed interface logic conversion
• System controller glue logic

Complex Programmable Logic Devices Procurement Notes

Verify the package type matches the 'JU' suffix, which corresponds to the 28-lead Plastic J-leaded Chip Carrier (PLCC). Confirm the '-15' speed grade aligns with the required 15 ns maximum delay specifications for the target operating voltage. Ensure the design environment supports the specific compiler mode selection for pin-keeper configuration if utilized.

Complex Programmable Logic Devices Selection Notes

Select this component when maximizing logic density in a small package is critical. The -15 speed grade offers a 15 ns max delay at 3V and 10 ns at 5V. Consider the Industrial temperature range (-40°C to +85°C) for broader environmental compatibility compared to commercial variants. Verify that the 20 flip-flop count and 171 total product terms meet the design's complexity requirements.

Complex Programmable Logic Devices Part Context

This device belongs to the ATF750LVC family, which is an enhanced superset of the legacy 22V10 architecture. It maintains architectural compatibility with ATV750B hardware and software tools. The 'JU' designation specifically identifies the 28-lead PLCC package variant within the industrial temperature grade lineup.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other parts from the ATF750LVC series with different package options, such as ATF750LVC-15PU (PDIP), ATF750LVC-15SU (SOIC), or ATF750LVC-15XU (TSSOP), provided the physical footprint allows for adaptation.
