USE ULTRA37000™ FOR ALL NEW DESIGNS CY7C372i UltraLogic™ 64-Macrocell Flash CPLD Features Functional Description • 64 macrocells in four logic blocks The CY7C372i 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 CY7C372i 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. • 32 I/O pins • Five dedicated inputs including two clock pins • In-System Reprogrammable (ISR™) Flash technology — JTAG interface • Bus Hold capabilities on all I/Os and dedicated inputs Like all of the UltraLogic™ FLASH370i devices, the CY7C372i is electrically erasable and 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. • No hidden delays • High speed — fMAX = 125 MHz — tPD = 10 ns — tS = 5.5 ns — tCO = 6.5 ns • Fully PCI compliant The 64 macrocells in the CY7C372i are divided between four logic blocks. Each logic block includes 16 macrocells, a 72 x 86 product term array, and an intelligent product term allocator. • 3.3V or 5.0V I/O operation • Available in 44-pin PLCC, TQFP, and CLCC packages • Pin-compatible with the CY7C371i 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.

Document #: 38-03033 Rev. *A Page 2 of 13 USE ULTRA37000™ FOR ALL NEW DESIGNS Functional Description Like all members of the FLASH370i family, the CY7C372i is rich in I/O resources. Every two macrocells in the device feature an associated I/O pin, resulting in 32 I/O pins on the CY7C372i. In addition, there are three dedicated inputs and two input/clock pins. Finally, the CY7C372i 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 CY7C372i remain the same. Logic Block The number of logic blocks distinguishes the members of the FLASH370i family. The CY7C372i includes four 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 a single pass through the device. 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 FLASH370 PLDs. Note that product term allocation is handled by software and is invisible to the user. I/O Macrocell Half of the macrocells on the CY7C372i have separate I/O pins associated with them. In other words, each I/O pin is shared by two macrocells. The input to the macrocell is the sum of between 0 and 16 product terms from the product term allocator. The macrocell includes a register that can be optionally bypassed. It also has polarity control, and two global clocks to trigger the register. The I/O 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. Buried Macrocell 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- Document #: 38-03033 Rev. *A CY7C372i boring macrocell. The output of all buried macrocells is sent directly to the PIM regardless of its configuration. Programmable Interconnect Matrix The Programmable Interconnect Matrix (PIM) connects the four logic blocks on the CY7C372i 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. Programming For an overview of ISR programming, refer to the FLASH370i 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.” 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. 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 VCCIO pins are connected to a 5.0V source, the I/O voltage levels are compatible with 5.0V systems. When VCCIO 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. Bus Hold Capabilities on all I/Os and Dedicated Inputs 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. Design Tools Development software for the CY7C372i is available from Cypress’s Warp™, Warp Professional™, and Warp Enterprise™ software packages. Please refer to the data sheets on these products for more details. Cypress also actively supports almost all third-party design tools.
