PAL20X10AMW883B

Programmable Logic Device Pld Overview

The PAL20X10AMW/883B is a high-performance Programmable Logic Device (PLD) manufactured by Advanced Micro Devices (AMD). It belongs to the PAL20X10 family, featuring an Over-The-Top (OT) architecture with 20 dedicated inputs and 10 I/O lines. The device utilizes a 20-pin Ceramic Dual Flatpack (CDFP) package, suitable for military and aerospace applications requiring MIL-STD-883 compliance. Key electrical parameters include a maximum propagation delay of 35 ns and a maximum operating frequency of 18 MHz. It operates within a temperature range of -55°C to +125°C and supports TTL logic levels.

Programmable Logic Device Pld Feature Summary

• PAL20X10 OT PLD Architecture: Provides 20 dedicated inputs and 10 I/O lines with macrocell output structures.
• High-Speed Performance: Features a typical propagation delay of 35 ns and a maximum clock frequency of 18 MHz.
• Military Grade Packaging: Housed in a 20-lead CDFP (Ceramic Dual Flatpack) package compliant with MIL-STD-883 standards.
• Extended Temperature Range: Designed for reliable operation across the full military temperature range of -55°C to +125°C.

Programmable Logic Device Pld Applications

• Military avionics systems requiring radiation-hardened or high-reliability logic components.
• Aerospace control units utilizing MIL-STD-883 qualified ceramic packages.
• High-speed digital signal processing interfaces needing low propagation delay.
• Complex glue logic replacement in ruggedized electronic assemblies.

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the /883B suffix, which indicates MIL-STD-883 screening. Confirm the specific speed grade (e.g., 35ns) matches the application requirements. Ensure the CDFP package footprint is compatible with the target PCB design. Check for any lot traceability documentation required for defense contracts. Validate that the TTL input/output levels align with the system voltage specifications.

Programmable Logic Device Pld Selection Notes

Select this component when a high-density PLD with 20 inputs and 10 I/Os is needed in a ceramic flatpack. Compare against PAL20V8 variants if fewer outputs are sufficient. Consider the 35ns delay for timing-critical paths. Ensure the design accommodates the 5V supply requirement typical of TTL-compatible PAL devices. Verify thermal management capabilities for the -55°C to +125°C operating range.

Programmable Logic Device Pld Part Context

The PAL20X10 series represents AMD's advanced programmable logic technology, offering greater flexibility than standard PALs through its OT architecture. The /883B designation signifies military-grade screening and packaging. This part is part of the broader PAL family, which was widely used before the dominance of CPLDs and FPGAs. It remains relevant for legacy system maintenance and specialized high-reliability applications.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific /883B military qualification. Generic PAL20X10 devices lack the MIL-STD-883 screening. Verify compatibility with existing programming tools and fuse maps. Consider modern FPGA alternatives for new designs, though they may require significant redesign.
