ATV2500B-15KC

Complex Programmable Logic Devices Overview

The ATV2500B-15KC is a high-density UV-erasable programmable logic device manufactured by Microchip Technology (formerly Atmel). It features a fully connected logic array with 416 product terms and 24 macrocells, providing 48 flip-flops. The component operates at a typical pin-to-pin delay of 7 ns, with a maximum clock frequency of 52 MHz under external feedback conditions. It utilizes a 44-lead windowed ceramic J-leaded chip carrier package (JLCC) and supports a commercial operating temperature range of 0°C to 70°C. The device runs on a 5V supply and includes features such as selectable D/T-type registers and combinatorial sum terms.

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 416 product terms and 24 macrocells containing 48 total flip-flops.
• Typical 7 ns pin-to-pin delay with a maximum external feedback frequency of 52 MHz.
• Flexible output macrocell structure allowing selectable D- or T-type flip-flops and combinatorial feedback.
• UV-erasable EPROM technology ensuring reprogrammability and high noise immunity.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement in industrial control systems
• State machine implementation requiring mixed synchronous/asynchronous clocking
• High-speed interface buffering and protocol conversion

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'KC' corresponds to the 44-lead Windowed Ceramic JLCC package and Commercial temperature range (0°C to 70°C). Confirm that the application environment does not require exposure to ultraviolet light, as the windowed package allows for potential unintentional erasure without proper shielding.

Complex Programmable Logic Devices Selection Notes

Select this part when a high gate count with flexible register configuration is required in a surface-mount compatible ceramic package. Ensure the design accounts for the 5V supply voltage tolerance and standby current specifications. Consider the UV window requirement for storage if the device is not permanently masked.

Complex Programmable Logic Devices Part Context

This component belongs to the ATV2500B family of high-speed UV EPROM PLDs. It serves as a direct software-compatible upgrade for older ATV2500H/L devices while offering enhanced features like T-type flip-flops and independent pin clocking. The 'KC' suffix specifically denotes the commercial grade windowed ceramic variant within the broader ATV2500B lineup.

Complex Programmable Logic Devices Replacement Considerations

The ATV2500B-15JC (PLCC package) offers identical electrical performance but requires a different footprint. For military applications, the ATV2500B-15KM or ATV2500B-15LM variants provide the same functionality across the -55°C to 125°C range.
