CY37032P44-125AXC

Complex Programmable Logic Devices Overview

The CY37032P44-125AXC is a 5V Ultra37000 CPLD featuring 32 macrocells and 37 I/O pins in a 44-lead TQFP package. It operates within the industrial temperature range of -40°C to +85°C with a supply voltage of 5V ± 0.5V. The device supports VCCO levels of either 5V or 3.3V, providing flexibility for mixed-voltage interfaces. Electrical specifications include a maximum propagation delay (tPD) of 12.5 ns and a maximum operating frequency (fMAX) of 125 MHz. Configuration data is stored in EEPROM, enabling In-System Reprogrammability via JTAG.

Complex Programmable Logic Devices Feature Summary

• In-System Reprogrammable (ISR) architecture using EEPROM storage
• PCI Local Bus Specification compliant
• IEEE 1149.1 JTAG interface for boundary scan and programming
• Programmable bus-hold capabilities on all I/Os

Complex Programmable Logic Devices Applications

• PCI-compatible system logic
• High-density programmable logic solutions
• Mixed-voltage interface bridging

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'AXC' against official Infineon documentation to confirm lead-free status and exact package variant. Confirm that the 125 speed bin meets the timing requirements for the target application. Ensure the design accounts for the 5V programming requirement inherent to this device family.

Complex Programmable Logic Devices Selection Notes

Select this component when 32 macrocells are sufficient for the logic density. The 125 MHz speed bin offers a balance between performance and power. Use the 5V version if the system requires 5V TTL output levels or needs to interface directly with 5V buses while maintaining 3.3V tolerance on inputs.

Complex Programmable Logic Devices Part Context

This part belongs to the Ultra37000 family of CMOS CPLDs manufactured by Cypress Semiconductor, now part of Infineon Technologies. The family provides high-density programmable logic with a simple timing model and consistent pinouts across densities to simplify design migration.

Complex Programmable Logic Devices Replacement Considerations

Check for updated Infineon product lines such as the XCF series or other CPLD families. Verify pinout compatibility and electrical characteristics before substituting with generic CPLDs.
