CY7C375IL-66AC

Complex Programmable Logic Devices Overview

The CY7C375IL-66AC is a Flash-based Complex Programmable Logic Device (CPLD) belonging to the UltraLogic family manufactured by Cypress Semiconductor. It integrates 128 macrocells and supports up to 128 I/O pins, providing high-density logic capabilities in a single package. The device utilizes non-volatile Flash technology, enabling system-in-system reprogrammability without the need for external configuration memory. It operates within a standard voltage range of 4.75V to 5.25V and features a maximum propagation delay of 10ns, suitable for general-purpose digital logic applications requiring reconfigurability.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells with 128 I/Os for complex logic implementation
• Non-volatile Flash architecture allowing System-In-System Reprogrammability (ISR)
• Maximum propagation delay of 10 ns at 66 MHz operation
• CMOS technology with 4.75V to 5.25V supply voltage range

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement
• Interface bridging between different voltage domains or protocols
• Prototyping and final production designs requiring field reprogrammability

Complex Programmable Logic Devices Part Context

This component is part of the Cypress UltraLogic CPLD series, which succeeded earlier PLD families. The CY7C375I variant specifically denotes the 128-macrocell density. The suffix 'L' typically indicates a lead-free or specific environmental compliance variant, while '66AC' specifies the speed grade and commercial temperature range. This places it in the mid-range density category of the UltraLogic portfolio, balancing pin count and logic resources.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements should be sought from the Infineon Technologies CY7C375I series, as Cypress's semiconductor assets were acquired by Infineon. Verify that the substitute maintains the 128 macrocell count, 160-TQFP package, and 10ns speed grade. Ensure the replacement supports the required 5V operation and Flash-based non-volatility.
