CY37128VP100-125AXC

Complex Programmable Logic Devices Overview

The CY37128VP100-125AXC is a 5V In-System Reprogrammable (ISR) Complex Programmable Logic Device (CPLD) from the Ultra37000 family. It features 128 macrocells, 69 I/O pins, and 5 dedicated inputs within a 100-lead TQFP package. The device operates at a maximum frequency of 125 MHz with a worst-case propagation delay of 10 ns. It supports both 5V and 3.3V I/O levels via VCCO connections and includes IEEE 1149.1 JTAG interface for boundary scan and reconfiguration.

Complex Programmable Logic Devices Feature Summary

• In-System Reprogrammable (ISR) capability via JTAG interface
• Simple timing model with no fanout or expander delays
• Programmable bus-hold on all I/Os to reduce system noise
• Flexible clocking with four synchronous clocks per logic block

Complex Programmable Logic Devices Applications

• PCI Local Bus compliant logic interfacing
• High-density programmable logic solutions
• System design changes without pinout modifications

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Infineon distributors. Confirm RoHS compliance status as lead-free packages are available. Check for moisture sensitivity handling requirements during storage and assembly.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 128 macrocells with 69 I/Os in a TQFP-100 package. Ensure voltage supply matches 5V operation for full feature access. Consider speed bin 125 MHz if 10 ns propagation delay meets timing constraints.

Complex Programmable Logic Devices Part Context
