CY37064VP100-143AXC

Complex Programmable Logic Devices Overview

The CY37064VP100-143AXC is a 5V In-System Reprogrammable (ISR) Complex Programmable Logic Device (CPLD) from the Ultra37000 family. It features 64 macrocells, 69 I/O pins, and four dedicated inputs. The device operates within an industrial temperature range of -40°C to +85°C and supports both 5V and 3.3V I/O levels via VCCO connections. It achieves a maximum operating frequency of 143 MHz with a typical propagation delay of 8.5 ns. The architecture includes a Programmable Interconnect Matrix (PIM), intelligent product term allocation, and IEEE 1149.1 JTAG support for boundary scan and reconfiguration.

• High-density glue logic replacement
• System controller and address decoding
• Protocol conversion and buffering

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed bin (-143) and package type (100-pin TQFP) against design requirements. Confirm that the industrial temperature grade (-40°C to +85°C) meets environmental specifications. Ensure programming infrastructure supports 5V ISR operations as required by this device variant.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 64 macrocells with high pin count flexibility. The -143 speed bin offers 143 MHz performance suitable for moderate-speed synchronous systems. Consider the 3.3V version if system power consumption is a primary constraint, though this 5V part allows mixed-voltage interfacing.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 CPLD family, which provides scalable logic density from 32 to 512 macrocells. The family shares a consistent architecture and simple timing model across densities, facilitating design migration between different capacity devices within the same series.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, 100-pin TQFP package, and 143 MHz speed grade. Verify compatibility with existing JTAG programming tools and ensure the substitute supports ISR functionality if in-system updates are required.
