CY7C330-66JC

Programmable Logic Device Pld Overview

The CY7C330-66JC is a high-performance Flash PLD from Cypress Semiconductor, part of the UltraLogic family. It features 128 macrocells and supports operation up to 66 MHz. The device utilizes non-volatile Flash technology for instant-on capability and reprogrammability without UV erasure. It is housed in a 44-pin Plastic Quad Flatpack (PQFP) package with J-leads, suitable for surface-mount applications. Key electrical parameters include a propagation delay of 15 ns and a supply voltage range of 4.5V to 5.5V.

Programmable Logic Device Pld Feature Summary

• 128 Macrocells with 32 I/O lines
• Flash-based non-volatile configuration
• 66 MHz maximum operating frequency
• 44-pin PQFP package

Programmable Logic Device Pld Applications

• System logic replacement
• Address decoding
• Bus buffering

Programmable Logic Device Pld Procurement Notes

Verify the specific speed grade suffix '66' against the manufacturer's datasheet to confirm the 66 MHz timing characteristics. Ensure the 'JC' suffix corresponds to the correct temperature range and package variant as defined in official Cypress documentation. Cross-reference the RoHS status and end-of-life notices directly with the supplier or manufacturer archives.

Programmable Logic Device Pld Selection Notes

Select this component when a reprogrammable logic solution with instant-on capability is required. Compare the 128 macrocell count and 32 I/O capacity against design requirements. Verify that the 4.5V to 5.5V VCC range matches the system power supply. Consider the 44-pin PQFP footprint for PCB layout compatibility.

Programmable Logic Device Pld Part Context

This part belongs to the Cypress UltraLogic Flash CPLD series, which combines the flexibility of PLDs with the non-volatility of Flash memory. It serves as a drop-in replacement for older EPROM-based PLDs like the GAL or PAL families, offering easier programming and higher density within a similar pin count.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes may include other Cypress Flash PLDs with similar macrocell counts, such as the CY7C372 or CY7C374 series, provided the I/O count and package match. Verify pin-to-pin compatibility and timing specifications before substitution.
