EP224PC-7

Programmable Logic Device Pld Overview

The EP224PC-7 is an Altera programmable logic device (PLD) belonging to the EP220/EP224 family. It features a flexible I/O architecture and implements 150 usable gates of custom user logic functions, equivalent to 8 macrocells. The device operates within an input voltage range of 4.75V to 5.25V and has a typical speed of 7.5 ns. It is housed in a 24-pin DIP package with through-hole mounting.

Programmable Logic Device Pld Feature Summary

• EPROM-based programmable logic technology
• Flexible I/O architecture for custom logic implementation
• Through-hole 24-DIP packaging

Programmable Logic Device Pld Applications

• General-purpose digital logic replacement
• Interface bridging between different logic families
• Simple state machine implementation

Programmable Logic Device Pld Procurement Notes

Verify the component is genuinely manufactured by Intel/Altera, as counterfeits exist in the market. Confirm the specific suffix '7' indicates the 7.5 ns speed grade. Ensure the package is the standard 24-pin PDIP variant. Request original manufacturer documentation or trusted distributor certificates to validate authenticity before purchase.

Programmable Logic Device Pld Selection Notes

Select this part when a small number of macrocells are sufficient for logic reduction tasks. The EPROM technology allows for reprogramming but requires UV erasure. Consider the 7.5 ns propagation delay for timing constraints. This device is suitable for legacy systems requiring parallel I/O flexibility without complex FPGA resources.

Programmable Logic Device Pld Part Context

The EP224PC-7 is part of the EP220/EP224 series, which were among Altera's early EPLD offerings. These devices bridge the gap between fixed-function gate arrays and more complex FPGAs. The family utilizes EPROM technology, allowing field reprogrammability, though it lacks the density of modern Cyclone or Arria series devices.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may be limited due to the age of the EPROM PLD technology. Verify compatibility with any existing UV erasing equipment if reprogramming is required. Check for newer CPLD alternatives from Intel or other vendors that offer similar gate counts with SRAM or Flash technology for easier reconfiguration.
