CY37128P100-125AXI

Complex Programmable Logic Devices Overview

The CY37128P100-125AXI is a 5V Ultra37000 CPLD featuring 128 macrocells and up to 69 I/O pins in a 100-lead TQFP package. It operates with a VCC supply of 4.5V to 5.5V and supports 5V or 3.3V I/O levels via VCCO connections. The device offers a maximum propagation delay (tPD) of 6.5 ns and a maximum frequency (fMAX) of 167 MHz. It includes In-System Reprogrammable (ISR) capabilities via JTAG, PCI compatibility, and programmable bus-hold on all I/Os.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells with 69 I/O pins in a 100-lead TQFP package
• Maximum propagation delay of 6.5 ns and fMAX of 167 MHz
• In-System Reprogrammable (ISR) via JTAG interface
• PCI Local Bus Specification compliant

Complex Programmable Logic Devices Applications

• PCI-compatible system logic
• High-density programmable logic solutions
• Bus-interface applications requiring noise reduction

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed bin (-125) matches the required timing constraints of 6.5 ns tPD and 167 MHz fMAX. Confirm that the 5V supply requirement aligns with the target system power rails. Ensure the 100-lead TQFP package footprint is compatible with the PCB design.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 128 macrocells and high-speed performance up to 167 MHz. The 5V version allows flexible interfacing to both 5V and 3.3V buses through VCCO configuration. Consider the -125 speed grade if system timing requires a maximum delay of 6.5 ns.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 family of CMOS CPLDs from Infineon Technologies (formerly Cypress Semiconductor). The family provides high-density programmable logic with consistent pinouts across densities, simplifying design migration between different macrocell counts within the same series.

Complex Programmable Logic Devices Replacement Considerations

Other devices in the Ultra37000 family, such as the CY37128VP100-125AXI, offer similar functionality but operate at 3.3V. Verify voltage compatibility before substitution.
