ATF750C-15NM/883

Complex Programmable Logic Devices Overview

The ATF750C-15NM/883 is a high-speed, electrically-erasable CPLD from the ATF750C series. It features 20 macrocells, 10 I/Os, and operates at 5V with a maximum propagation delay of 15 ns. The device supports up to 71 MHz external feedback frequency. It includes 20 D/T-type flip-flops, programmable pin-keepers, and asynchronous resets. Designed for military applications (-55°C to +125°C), it offers 1000 erase/write cycles, 20-year data retention, and 2000V ESD protection.

Complex Programmable Logic Devices Feature Summary

• High-density logic: 20 macrocells, 171 product terms, and 20 sum terms in a 28-pin CLCC package.
• Advanced flip-flop flexibility: Individual D/T-type configuration, direct input pin clocking, or product term clocking.
• Military-grade reliability: Operates from -55°C to +125°C with 1000 erase/write cycles and 20-year data retention.
• Enhanced I/O control: Programmable pin-keeper circuits prevent floating inputs and reduce power consumption.

Complex Programmable Logic Devices Applications

• Complex state machine implementation requiring buried registers.
• Military systems requiring MIL-STD-883 compliance.
• Address decoding and bus interface logic.
• Replacement for legacy 22V10-based designs with higher density.

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix /883 indicates MIL-STD-883 Class B compliance. Confirm the 'N' suffix corresponds to the 28-pad Ceramic Leadless Chip Carrier (LCC) package. Ensure design tools support the V750 mnemonic for proper fuse pattern programming.

Complex Programmable Logic Devices Selection Notes

Select this part for 5V logic applications requiring 15 ns speed and military temperature range. Compare against ATF750CL-15NM/883 if lower standby current (1 mA vs 90 mA) is critical. Verify package compatibility with existing PCB footprints for the 28L LCC form factor.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF750C family, which supersedes the ATV750B/L and ATV750/L devices. It provides backward compatibility while offering increased logic resources, including additional flip-flops and product terms, within the same 24/28-pin footprint constraints.

Complex Programmable Logic Devices Replacement Considerations

Direct replacement for ATV750(L) and ATV750B(L). When migrating from ATV750, use the V750 cross-programming mode to disable pin-keepers and maintain JEDEC file compatibility.

Complex Programmable Logic Devices FAQ

What is the maximum operating frequency?

The maximum external feedback frequency is 71 MHz, calculated based on the 15 ns propagation delay and setup times.

How are unused inputs handled?

Programmable pin-keeper circuits can be enabled to hold unused inputs at their last state, eliminating the need for external pull-up resistors.

Can individual flip-flops use different clocks?

Yes, each of the 20 flip-flops can be individually clocked by its own product term or directly from an input pin.
