CY37064P100-125AC

Complex Programmable Logic Devices Overview

The CY37064P100-125AC is a 5V Ultra37000 CPLD featuring 64 macrocells and up to 69 I/O pins. It operates within an industrial temperature range of -40°C to +85°C with a VCC supply of 5V ± 0.5V. The device supports 5V or 3.3V I/O levels via VCCO connections, ensuring PCI compatibility. Key electrical parameters include a maximum propagation delay (tPD) of 10 ns and a maximum frequency (fMAX) of 125 MHz for the 125 speed bin.

Complex Programmable Logic Devices Feature Summary

• In-System Reprogrammable (ISR) architecture allowing design changes without pinout or timing modifications.
• Simple timing model with no fanout, expander, or routing delays; worst-case tPD is 10 ns.
• Intelligent product term allocator providing flexible distribution of up to 16 product terms per macrocell.
• Programmable bus-hold capabilities on all I/Os to reduce system noise and simplify prototyping.

Complex Programmable Logic Devices Applications

• PCI Local Bus interface designs requiring high-density logic.
• Systems needing in-field reconfiguration without board respins.
• Prototyping environments utilizing programmable bus-hold features.

Complex Programmable Logic Devices Procurement Notes

Verify the specific package type associated with the 'P' suffix in the part number against official datasheets, as package options vary across the family. Confirm that the 125 speed bin meets the target system clock requirements. Ensure the manufacturing source is authorized, as this component belongs to a legacy family with potential availability constraints.

Complex Programmable Logic Devices Selection Notes

Select this device when 64 macrocells are sufficient for the logic density requirements. The 125 speed bin offers a balance between performance and power consumption compared to faster bins. Verify that the 5V VCC supply aligns with the system power rails, as 3.3V devices require different supply configurations. Check if the 69 I/O count fits the available package footprint.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 family of CMOS CPLDs manufactured by Cypress Semiconductor, which was later acquired by Infineon Technologies. The family provides high-density programmable logic solutions with consistent pinouts across densities to simplify design migration. The CY37064 represents the entry-level density in this series.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, 125 MHz speed grade, and PLCC-84 package. Verify ISR compatibility and JTAG interface support. Consider newer CPLD families from Infineon or other vendors if lead-free or RoHS compliance is strictly required for new designs, noting that pinouts may differ.
