9020DM/B

Overview

The EP9020DM/B is a high-performance, 16-macrocell Classic EPLD manufactured by Rochester Electronics. It supports pipelined data rates of up to 100 MHz and offers combinatorial speeds with propagation delays as low as 10 ns. The device features a programmable I/O architecture with up to 20 inputs or 16 outputs and two clock pins. It is available in a 24-pin small-outline integrated circuit (SOIC) plastic package.

Feature Summary

• High-performance 16-macrocell architecture supporting pipelined data rates up to 100 MHz
• Programmable I/O architecture providing up to 20 inputs or 16 outputs
• Individually programmable macrocells configurable as D, T, JK, or SR flip-flops
• Programmable clock option for independent clocking of all registers

Applications

• Pipelined data processing systems requiring high-speed logic
• Combinatorial logic applications needing fast propagation delays
• Counter circuits operating at frequencies up to 100 MHz
• General-purpose programmable logic integration in industrial equipment

Procurement Notes

Verify the specific suffix 'DM/B' against official documentation to confirm the 24-pin SOIC plastic package variant. Confirm RoHS compliance status through the manufacturer's current certification records. Ensure the ordering part number matches the exact pin count and package type required for your PCB footprint. Request the latest programming file compatibility list to ensure support for legacy designs.

Selection Notes

Select this component when a 16-macrocell capacity is sufficient for the design logic requirements. Choose the DM/B suffix specifically for the 24-pin SOIC plastic package form factor. Consider the 10 ns propagation delay for timing-critical combinatorial paths. Verify that the 100 MHz pipelined rate meets the system throughput needs compared to faster CPLD alternatives.

Part Context

This device belongs to the Classic EPLD family from Altera, now supported by Rochester Electronics for lifecycle extension. It is functionally compatible with other variants such as the EP610 series, sharing similar macrocell architectures. The product line targets applications requiring reliable, single-time-programmable logic solutions where standard availability has ceased.

Replacement Considerations

Public confirmed substitutes include EP610, EP610I, EP610T, EP610-XX/B, EP600I, and PALCE610. These parts are pin-, function-, and programming file-compatible. Verify package dimensions before substitution.
