EP224LC-10

Programmable Logic Device Pld Overview

The Altera EP224LC-10 is a Complex Programmable Logic Device (CPLD) belonging to the EPM220 family. It features 24 macrocells and supports up to 24 I/O pins within a single package. The device utilizes Flash non-volatile memory technology, allowing for rapid reprogramming without external configuration hardware. It operates on a single 3.3V supply voltage and is rated for commercial temperature ranges from 0°C to +70°C. The component is housed in a 44-pin TQFP package, providing a compact solution for low-density logic applications requiring high reliability and fast turnaround times.

Programmable Logic Device Pld Feature Summary

• 24 Macrocells with 24 I/Os in a 44-pin TQFP package
• Non-volatile Flash memory for instant power-up operation
• Single 3.3V supply voltage operation
• High-speed performance with 10ns propagation delay

Programmable Logic Device Pld Applications

• Address decoding and bus bridging
• Simple state machine implementation
• Interface translation between different voltage domains
• Logic replacement for discrete gate arrays

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix '10' corresponds to the 10ns speed grade when sourcing replacements. Confirm RoHS compliance status as older batches may differ. Check for obsolescence notices from Intel/Altera distributors, as this part belongs to an older generation of CPLDs. Ensure the TQFP-44 footprint matches the target PCB design constraints.

Programmable Logic Device Pld Selection Notes

Select this component when a small number of macrocells are required with non-volatile storage capabilities. Compare against the EPM240 series if additional I/O count is needed. Verify that the 3.3V I/O levels are compatible with the connected system components. Consider the TQFP-44 package availability relative to surface mount assembly requirements.

Programmable Logic Device Pld Part Context

The EP224LC-10 is part of the EPM220 family, designed for cost-sensitive applications requiring simple programmable logic. It serves as a drop-in replacement for fixed-function logic gates in industrial and consumer electronics. The Flash-based architecture distinguishes it from earlier EEPROM-based CPLDs by offering faster programming cycles and higher endurance.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible substitutes include other members of the EPM220 family such as the EP240 series, provided the macrocell count meets design requirements. Verify electrical specifications match exactly before substitution.
