7C375i66

The CY7C375i is an In-System Reprogrammable Complex Programmable Logic Device (CPLD) and is part of the FLASH370i™ family of high-density, high-speed CPLDs. Like all members of the FLASH370i family, the CY7C375i is designed to bring the ease of use and high performance of the 22V10 to high-density PLDs.

Like all of the UltraLogic™ FLASH370i devices, the CY7C375i is electrically erasable and In-System Reprogrammable (ISR), which simplifies both design and manufacturing flows thereby reducing costs. The Cypress ISR function is implemented through a JTAG serial interface. Data is shifted in and out through the SDI and SDO pins. The ISR interface is enabled using the programming voltage pin (ISREN). Additionally, because of the superior routability of the FLASH370i devices, ISR often allows users to change existing logic designs while simultaneously fixing pinout assignments.
