EP324DC-25

Programmable Logic Device Pld Overview

The EP324DC-25 is a UV-erasable programmable logic device (PLD) manufactured by Altera. It utilizes a PAL-type architecture with CMOS technology and is housed in a windowed ceramic dual in-line package (CDIP-20). The device features 8 macrocells, supporting up to 18 inputs and 8 outputs. Its maximum operating frequency is specified at 58.8 MHz, with a propagation delay of 25 ns. The component operates within a commercial temperature range of 0°C to +70°C and does not comply with RoHS standards.

• Test and measurement equipment prototyping

Programmable Logic Device Pld Part Context

This component belongs to Altera's legacy UV-erasable PLD portfolio, distinct from modern FPGA or EEPROM-based CPLD families like the APEX or MAX series. The 'DC' suffix indicates a commercial temperature range, while the '25' denotes the speed grade. These devices are characterized by their windowed packages, which allow erasure via ultraviolet light, a feature absent in standard plastic-packaged modern programmable logic.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements are limited due to the specific UV-erasable requirement. Modern equivalents typically require EEPROM-based CPLDs (e.g., MAX 10 or EPM series), which lack UV windows and require electrical erasure. Designers must verify voltage levels and timing constraints when migrating to non-UV-erasable technologies.
