CY37064VP44-100AXCT

Complex Programmable Logic Devices Overview

The CY37064VP44-100AXCT is a member of the Ultra37000 family of In-System Reprogrammable (ISR) CMOS Complex Programmable Logic Devices (CPLDs). Manufactured originally by Cypress Semiconductor and now part of Infineon Technologies, this specific variant operates at a 3.3V supply voltage. It features 64 macrocells, five dedicated inputs, and supports up to 44 I/O pins depending on the package configuration. The device belongs to the 100 MHz speed bin, characterized by a maximum propagation delay (tPD) of 15 ns and a maximum operating frequency (fMAX) of 100 MHz. It utilizes a JTAG-compliant interface for boundary scan and in-system programming.

Complex Programmable Logic Devices Feature Summary

• In-System Reprogrammable (ISR) capability via JTAG interface, allowing design changes without altering pinout or timing.
• High-density architecture with 64 macrocells, 80 product terms per logic block, and flexible product term allocation.
• PCI Local Bus specification compliant with 3.3V operation and 5V-tolerant I/Os.
• Programmable bus-hold capabilities on all I/Os to reduce system noise and simplify prototyping.

Complex Programmable Logic Devices Applications

• PCI-compatible digital logic interfacing
• System glue logic replacement
• State machine implementation
• Address decoding and control logic

Complex Programmable Logic Devices Procurement Notes

Verify that the component is sourced from authorized distributors to ensure authenticity, as the Ultra37000 family was originally produced by Cypress Semiconductor before its acquisition. Confirm the suffix 'XCT' corresponds to the specific temperature range and packaging requirements for the target application, noting that original documentation may reference Cypress branding.

Complex Programmable Logic Devices Selection Notes

Select the CY37064VP44-100AXCT when a design requires 64 macrocells with a guaranteed 100 MHz performance at 3.3V. Ensure the design fits within the 44-pin package constraints if using the TQFP or PLCC variants. Consider the ISR feature if field updates are required, and verify that the 5V-tolerant I/Os meet the interface requirements of the connected systems.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 CPLD family, which offers a range of densities from 32 to 512 macrocells. The 'V' suffix indicates 3.3V operation, while the number '064' denotes the 64-macrocell density. The 'P44' refers to the 44-pin package option, and '100' specifies the 100 MHz speed grade. Infineon Technologies continues to support this legacy line acquired from Cypress.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other CY37064 variants with different speed bins (e.g., CY37064VP44-150AXCT for 150 MHz) or package options. For higher density needs, consider CY37128 or CY37256 models which maintain pinout compatibility across certain package types.
