ATF750LVC-15JC

Complex Programmable Logic Devices Overview

The ATF750LVC-15JC is a high-performance CMOS complex programmable logic device (CPLD) utilizing electrically-erasable technology. It operates within a 3.0V to 5.5V supply range and features 24 pins with 12 dedicated inputs, 10 I/Os, and one clock input. The architecture provides 171 total product terms, 20 sum terms, and 20 individually configurable D- or T-type flip-flops. Maximum pin-to-pin propagation delay is 10 ns at 5V operation and 15 ns at 3V operation. The device supports up to 1000 erase/write cycles and includes programmable pin-keeper circuits.

Complex Programmable Logic Devices Procurement Notes

Verify the package suffix 'JC' against official ordering tables. The provided datasheet lists 'JU', 'PU', 'SU', and 'XU' suffixes for industrial temperature ranges. Confirm if 'JC' corresponds to a specific commercial variant or a discontinued package type before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring high logic density in a 24-pin footprint. Ensure the design utilizes the 3.0V–5.5V operating range. Consider the -15 speed grade for applications requiring maximum 15 ns delays at 3V or 10 ns at 5V. Verify compiler settings for pin-keeper enablement if unused pins are present.

Complex Programmable Logic Devices Part Context

The ATF750LVC is part of the Atmel 750 series, which serves as a superset of the 22V10 architecture. It offers enhanced flexibility through increased product terms and buried registers compared to standard PAL devices. The device is architecturally compatible with existing ATV750B designs.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other ATF750LVC variants with different speed grades or packages (e.g., ATF750LVC-15JU). Cross-family replacements may require retargeting in Synario or WinCupl compilers.
