Like all members of the FLASH370i family, the CY7C374i is designed to bring the ease of use as well as PCI Local Bus Specification support and high performance of the 22V10 to high-density CPLDs. Like all of the UltraLogic™ FLASH370i devices, the CY7C374i 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 pin. 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 128 macrocells in the CY7C374i are divided between eight logic blocks. Each logic block includes 16 macrocells, a 72 x 86 product term array, and an intelligent product term allocator.

The output of all buried macrocells is sent directly to the PIM regardless of its configuration. 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. Programmable Interconnect Matrix The Programmable Interconnect Matrix (PIM) connects the eight logic blocks on the CY7C374i to the inputs and to each other. All inputs (including feedbacks) travel through the PIM. There is no speed penalty incurred by signals traversing the PIM. Like all members of the FLASH370i family, the CY7C374i is rich in I/O resources. Every two macrocells in the device feature an associated I/O pin, resulting in 64 I/O pins on the CY7C374i. In addition, there is one dedicated input and four input/clock pins. Programming For an overview of ISR programming, refer to the F LASH370i Family data sheet and for ISR cable and software specifications, refer to ISR data sheets. For a detailed description of ISR capabilities, refer to the Cypress application note, “An Introduction to In System Reprogramming with FLASH370i.” Finally, the CY7C374i features a very simple timing model. Unlike other high-density CPLD architectures, there are no hidden speed delays such as fanout effects, interconnect delays, or expander delays. Regardless of the number of resources used or the type of application, the timing parameters on the CY7C374i remain the same. PCI Compliance The FLASH370i family of CMOS CPLDs are fully compliant with the PCI Local Bus Specification published by the PCI Special Interest Group. The simple and predictable timing model of FLASH370i ensures compliance with the PCI AC specifications independent of the design. On the other hand, in CPLD and FPGA architectures without simple and predictable timing, PCI compliance is dependent upon routing and product term distribution. Logic Block The number of logic blocks distinguishes the members of the FLASH370i family. The CY7C374i includes eight logic blocks. Each logic block is constructed of a product term array, a product term allocator, and 16 macrocells. Product Term Array The product term array in the FLASH370i logic block includes 36 inputs from the PIM and outputs 86 product terms to the product term allocator. The 36 inputs from the PIM are available in both positive and negative polarity, making the overall array size 72 x 86. This large array in each logic block allows for very complex functions to be implemented in single passes through the device. 3.3V or 5.0V I/O Operation The FLASH370i family can be configured to operate in both 3.3V and 5.0V systems. All devices have two sets of VCC pins: one set, VCCINT, for internal operation and input buffers, and another set, VCCIO, for I/O output drivers. VCCINT pins must always be connected to a 5.0V power supply. However, the VCCIO pins may be connected to either a 3.3V or 5.0V power supply, depending on the output requirements. When V CCIO pins are connected to a 5.0V source, the I/O voltage levels are compatible with 5.0V systems. When V CCIO pins are connected to a 3.3V source, the input voltage levels are compatible with both 5.0V and 3.3V systems, while the output voltage levels are compatible with 3.3V systems. There will be an additional timing delay on all output buffers when operating in 3.3V I/O mode. The added flexibility of 3.3V I/O capability is available in commercial and industrial temperature ranges. Product Term Allocator The product term allocator is a dynamic, configurable resource that shifts product terms to macrocells that require them. Any number of product terms between 0 and 16 inclusive can be assigned to any of the logic block macrocells (this is called product term steering). Furthermore, product terms can be shared among multiple macrocells. This means that product terms that are common to more than one output can be implemented in a single product term. Product term steering and product term sharing help to increase the effective density of the FLASH370i CPLDs. Note that product term allocation is handled by software and is invisible to the user. Bus Hold Capabilities on all I/Os and Dedicated Inputs Half of the macrocells on the CY7C374i have I/O pins associated with them. The input to the macrocell is the sum of between 0 and 16 product terms from the product term allocator. The I/O macrocell includes a register that can be optionally bypassed, polarity control over the input sum-term, and two global clocks to trigger the register. The macrocell also features a separate feedback path to the PIM so that the register can be buried if the I/O pin is used as an input. In addition to ISR capability, a new feature called bus-hold has been added to all FLASH370i I/Os and dedicated input pins. Bus-hold, which is an improved version of the popular internal pull-up resistor, is a weak latch connected to the pin that does not degrade the device’s performance. As a latch, bus-hold recalls the last state of a pin when it is three-stated, thus reducing system noise in bus-interface applications. Bus-hold additionally allows unused device pins to remain unconnected on the board, which is particularly useful during prototyping as designers can route new signals to the device without cutting trace connections to VCC or GND. Buried Macrocell Design Tools The buried macrocell is very similar to the I/O macrocell. Again, it includes a register that can be configured as combinatorial, as a D flip-flop, a T flip-flop, or a latch. The clock for this register has the same options as described for the I/O macrocell. One difference on the buried macrocell is the addition of input register capability. The user can program the buried macrocell to act as an input register (D-type or latch) whose input comes from the I/O pin associated with the neigh- Development software for the CY7C371i is available from Cypress’s Warp2®, Warp2Sim™, and Warp3® software packages. All of these products are based on the IEEE-standard VHDL language. Cypress also actively supports third-party design tools from companies such as Synopsys, Mentor Graphics, Cadence, and Synario.

When the I/O is three-stated, the bus-hold circuit can weakly pull the I/O to a maximum of 4.0V if no leakage current is allowed. This voltage is lowered significantly by a small leakage current. Note that all I/Os are three-stated during ISR programming. Refer to the application note “Understanding Bus Hold” for additional information. 7. These are absolute values with respect to device ground. All overshoots due to system or tester noise are included. 8. Not more than one output should be tested at a time. Duration of the short circuit should not exceed 1 second. VOUT = 0.5V has been chosen to avoid test problems caused by tester ground degradation. 9.
