CY37032P44-125JXC

Product Overview

CY37032P44-125JXC is a 32-macrocell Cypress Ultra37000 complex programmable logic device associated with Cypress Semiconductor / Infineon. It is intended for deterministic control, address decoding and interface logic, where nonvolatile configuration, predictable timing and board-level logic integration are more important than the large reconfigurable fabric used in an FPGA. The complete ordering code identifies a specific speed, package and temperature option and must be preserved when qualifying replacement material.

This ordering variant belongs to the 5 V / 3.3 V Ultra37000 family. The -125 speed token identifies its timing grade. Package and pin count must be confirmed from the exact ordering table. It also carries a commercial-temperature ordering suffix. These suffix details affect PCB footprint, I/O availability, timing closure and environmental qualification; they are not cosmetic ordering differences.

Architecture and Technical Characteristics

Ultra37000 devices use in-system-reprogrammable macrocells and a programmable interconnect architecture for dense control and decode logic. The family supports nonvolatile configuration and board-level reprogramming, but I/O count, voltage option, timing and package availability change across CY37032 through CY37512 members. Those values are assigned only when the exact ordering code is confirmed.

Key Features

• Manufacturer / historical brand: Cypress Semiconductor / Infineon
• Full part number: CY37032P44-125JXC
• CPLD family: Cypress Ultra37000
• Logic capacity: 32 macrocells
• Logic organization: manufacturer-defined macrocell/function-block architecture
• Configuration technology: in-system reprogrammable nonvolatile CPLD
• Voltage class: 5 V / 3.3 V Ultra37000 family
• Speed-grade designator: -125; guaranteed timing must be taken from the exact device speed table
• Temperature / qualification: commercial-temperature ordering suffix
• Programming requirement: verify JTAG/ISP algorithm, chain file and programming-voltage conditions for the exact device
• Configuration file: blank stock requires the correct JEDEC, SVF or vendor-supported programming data before it can replace a programmed unit

Applications

• Address decoding and chip-select generation
• Reset, power sequencing and supervisory control
• Bus bridging, protocol glue and interface qualification
• Deterministic finite-state machines
• Industrial, communications and legacy platform maintenance

Design and Replacement Considerations

Before replacing this device, compare macrocell capacity, usable I/O for the selected package, core and I/O rails, input tolerance, global clock and reset resources, power-up behavior, JTAG pinout and guaranteed propagation/setup/clock-to-output timing. Preserve the original project and programming file. A blank CPLD does not contain the customer function, and a JEDEC or SVF file compiled for a related density or package must not be assumed compatible. When migrating to another family, recompile, rerun fitter constraints and perform timing and board-level voltage validation.

Quality & Sourcing

For CY37032P44-125JXC, Antrex Electronics can support stock and lead-time checks, full-suffix confirmation, package and date-code review, product photographs, label inspection and shipment planning. Buyers should state whether blank or pre-programmed parts are required and provide the target quantity, acceptable date code, packaging form and inspection requirements. For discontinued or long-stored CPLDs, recommended controls include traceability review, marking comparison, lead and ball-condition inspection, solderability evaluation and third-party electrical or X-ray testing when risk warrants it. OEMs, EMS providers, repair centers and component buyers may submit BOM lists and hard-to-find programmable-logic requirements for sourcing support.
