CY37512P208-83NXC

Complex Programmable Logic Devices Overview

The CY37512P208-83NXC is a complex programmable logic device (CPLD) from the Cypress Semiconductor APEX II family, now part of Infineon Technologies. It features 512 macrocells and supports up to 128 I/O pins within a 208-pin plastic quad flat package (PQFP). The device operates with a maximum system clock frequency of 83 MHz and utilizes a non-volatile Flash memory technology for configuration retention. Key electrical parameters include an operating voltage range typically centered around 3.3V, with specific supply requirements detailed in the official datasheet. It provides high-density logic capabilities suitable for complex digital design applications requiring reprogrammability.

Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer date code and lot number against the original Cypress Semiconductor specifications, as Infineon acquired the product line. Confirm the suffix 'NXC' corresponds to the lead-free, RoHS-compliant variant and the specific temperature grade. Ensure the package integrity is intact, as PQFP pins are susceptible to bending during handling. Cross-reference the part number with current Infineon inventory lists to confirm availability status and any potential obsolescence notices.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile CPLD with moderate density is required without the complexity of FPGA routing resources. Compare the 83 MHz speed grade against timing constraints of the target application. Consider the 208-pin package size relative to board space limitations. Evaluate power consumption differences between active and standby modes compared to volatile SRAM-based alternatives. Verify that the I/O voltage levels match the connected peripherals.

Complex Programmable Logic Devices Part Context

This part belongs to the APEX II family of CPLDs, originally developed by Cypress Semiconductor before its acquisition by Infineon Technologies. The APEX II series was designed to offer higher performance and density than previous generations while maintaining compatibility with standard JEDEC pinouts. The CY37512 designation indicates the 512 macrocell capacity within this architecture.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may include other Cypress/Infineon APEX II variants with adjusted I/O counts or speed grades. Third-party equivalents from vendors like Lattice or Altera require careful pin-to-pin compatibility checks and functional verification due to architectural differences between CPLD families.
