CY37192VP160-66AXC

Complex Programmable Logic Devices Overview

The CY37192VP160-66AXC is a Complex Programmable Logic Device (CPLD) from the Ultra37000 family, manufactured by Infineon Technologies. It features 192 macrocells and 125 I/O pins housed in a 160-lead TQFP package. Operating at a supply voltage of 3.3V with a maximum frequency of 66 MHz, it offers a propagation delay of 20 ns. The device utilizes EEPROM storage for non-volatile configuration and supports In-System Reprogrammability via JTAG.

Complex Programmable Logic Devices Feature Summary

• In-System Reprogrammable (ISR) CMOS architecture allowing design changes without pinout or timing modifications.
• Intelligent product term allocator providing flexible distribution of up to 16 product terms per macrocell.
• IEEE 1149.1-compliant JTAG interface supporting boundary scan and on-board programming.
• Programmable bus-hold capabilities on all I/Os to reduce system noise and simplify prototyping.

Complex Programmable Logic Devices Applications

• PCI Local Bus compliant logic interfacing
• High-density programmable logic solutions requiring fixed pinouts during redesign
• Systems needing in-field reconfiguration without board respins

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part number may be subject to obsolescence. Confirm that the specific suffix 'AXC' matches the required commercial temperature range and lead-free packaging specifications before integration into production designs.

Complex Programmable Logic Devices Selection Notes

Select this model when 192 macrocells and 125 I/Os are required within a 160-pin footprint. Ensure the design operates within the 3.3V VCC/VCCO constraints. Consider the 66 MHz speed bin if higher performance is not critical, as faster variants like the -83AXC exist for the same package.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 CPLD family, which provides high-density programmable logic with consistent pinouts across densities. The family allows migration between devices without changing board layouts, simplifying design upgrades and scaling.

Complex Programmable Logic Devices Replacement Considerations

For equivalent functionality, consider the CY37192VP160-83AXC for higher speed or CY37192VP160-100AXC for different timing characteristics. Verify package compatibility and electrical specifications before substitution.

Complex Programmable Logic Devices FAQ

Does the ISR feature affect the device's timing performance?

No, the Ultra37000 family features a simple timing model where design changes do not cause timing variations. All delays are worst-case and independent of routing or product term usage.

What is the purpose of the programmable bus-hold feature?

Bus-hold acts as a weak latch that maintains the last state of a pin when placed in a high-impedance state, reducing system noise in bus-interface applications and allowing unused pins to remain unconnected.

How many dedicated input pins does the CY37192VP160-66AXC have?

The device includes five dedicated inputs, which can be configured as input-only or input/clock pins to support flexible clocking architectures.
