CY37032P44-154AXI

Complex Programmable Logic Devices Overview

The CY37032P44-154AXI is a 5V In-System Reprogrammable (ISR) Complex Programmable Logic Device (CPLD) from the Ultra37000 family. It contains 32 macrocells and supports up to 37 I/O pins in a 44-lead PLCC package. The device operates with a 5V supply and features a maximum propagation delay of 7.5 ns, corresponding to a maximum frequency of 154 MHz. It includes five dedicated inputs, four of which function as clock pins. The architecture utilizes a Programmable Interconnect Matrix (PIM) for global routing.

Complex Programmable Logic Devices Feature Summary

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the component meets RoHS requirements if applicable to the target application. Ensure compatibility with existing ISR programming infrastructure.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 32 macrocells with a 154 MHz speed bin. The 44-lead PLCC package is suitable for surface mount designs. Verify voltage levels; VCCO determines output levels while VCC remains at 5V for programming.

Complex Programmable Logic Devices Part Context

This part belongs to the Ultra37000 CPLD family, originally developed by Cypress Semiconductor and now managed by Infineon Technologies. The family provides high-density programmable logic with consistent pinouts across different density options.

Complex Programmable Logic Devices Replacement Considerations

Check for direct substitutes within the Ultra37000 family such as CY37032 variants with different speed grades or packages. Verify pinout compatibility before substitution.
