CY37256VP208-100NXC

Complex Programmable Logic Devices Overview

The CY37256VP208-100NXC is a Flash PLD from the Ultra37000 family, manufactured by Cypress Semiconductor Corp. It features a propagation delay of 19 ns and operates on CMOS technology within a PBGA256 package. The device supports a maximum clock frequency of 62.5 MHz and functions with a supply voltage range of 3.0 V to 3.6 V, typically rated at 3.3 V. Designed for in-system reprogrammability via JTAG, it offers high-density logic capabilities suitable for complex digital designs requiring non-volatile configuration retention.

Complex Programmable Logic Devices Feature Summary

• Flash-based non-volatile architecture allowing instant-on functionality without external configuration memory.
• In-System Reprogrammable (ISR) capability via JTAG interface for design updates without pinout changes.
• High performance with 19 ns propagation delay and up to 62.5 MHz clock frequency.
• Supports 3.3V operation with wide voltage tolerance (3.0V to 3.6V).

Complex Programmable Logic Devices Applications

• Complex digital logic replacement in industrial control systems.
• Protocol conversion and bus bridging in communication equipment.
• State machine implementation in automotive embedded systems.
• Custom logic integration in networking infrastructure hardware.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '100NXC' against official Cypress/Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the PBGA256 form factor. Check for RoHS compliance status as original specifications may indicate non-compliance depending on manufacturing date. Confirm availability through authorized distributors or secondary markets due to potential discontinuation status.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile programmable logic is required to eliminate external configuration EEPROMs. Compare macrocell count and I/O pin density against alternative CPLDs if higher complexity is needed. Ensure the 3.3V supply rail matches the system design, as the device does not support lower voltages like 2.5V or 1.8V natively. Verify that the BGA256 package size fits within the mechanical constraints of the target enclosure.

Complex Programmable Logic Devices Part Context

This part belongs to the Ultra37000 series of Electrically Erasable Programmable Logic Devices (EPLDs). The series is characterized by its ISR technology, which allows designers to modify logic designs after assembly without altering the physical pin connections or timing characteristics. Cypress Semiconductor was later acquired by Infineon Technologies, which continues to support these legacy programmable logic families.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may include other parts from the Ultra37000 family with similar I/O counts but different speeds or densities. Cross-reference with Intel/Altera MAX 3000A or Xilinx Spartan-3E for functional equivalents, noting differences in programming interfaces and voltage requirements. Verify pin-to-pin compatibility before substituting.
