CY7C374i UltraLogic 128-Macrocell Flash CPLD Features Functional Description 128 macrocells in eight logic blocks The CY7C374i is an In-System Reprogrammable Complex Programmable Logic Device (CPLD) and is part of the 64 I/O pins FLASH370i family of high-density, high-speed CPLDs. Like Five dedicated inputs including four clock pins all members of the FLASH370i family, the CY7C374i is In-System Reprogrammable (ISR) Flash technology designed to bring the ease of use as well as PCI Local Bus Specification support and high performance of the 22V10 to JTAG interface high-density CPLDs. Bus Hold capabilities on all I/Os and dedicated inputs Like all of the UltraLogic FLASH370i devices, the CY7C374i No hidden delays is electrically erasable and In-System Reprogrammable (ISR), High speed which simplifies both design and manufacturing flows, thereby f = 125 MHz reducing costs. The Cypress ISR function is implemented MAX through a JTAG serial interface. Data is shifted in and out t = 10 ns PD through the SDI and SDO pin. The ISR interface is enabled t = 5.5 ns S using the programming voltage pin (ISR ). Additionally, EN t = 6.5 ns because of the superior routability of the FLASH370i devices, CO ISR often allows users to change existing logic designs while Fully PCI-compliant simultaneously fixing pinout assignments. 3.3V or 5.0V I/O operation The 128 macrocells in the CY7C374i are divided between Available in 84-pin PLCC, 84-pin CLCC, and 100-pin eight logic blocks. Each logic block includes 16 macrocells, a TQFP packages 72 x 86 product term array, and an intelligent product term Pin-compatible with the CY7C373i allocator.
