CY7C371i General Description

The CY7C371i 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 CY7C371i is designed to bring the ease of use and high performance of the
22V10, as well as PCI Local Bus Specification support, to high-density CPLDs.

Like all of the UltraLogic™ FLASH370i devices, the CY7C371i 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.

The 32 macrocells in the CY7C371i are divided between two logic blocks. Each logic block includes 16 macrocells, a 72 x 86 product term array, and an intelligent product term allocator.

The logic blocks in the FLASH370i architecture are connected with an extremely fast and predictable routing resource-the Programmable Interconnect Matrix (PIM). The PIM brings flexibility, routability, speed, and a uniform delay to the interconnect.

Like all members of the FLASH370i family, the CY7C371i is rich in I/O resources. Each macrocell in the device features an associated I/O pin, resulting in 32 I/O pins on the CY7C371i. In addition, there are three dedicated inputs and two input/clock pins.
