MACH111-5VC

Product Overview

MACH111-5VC is a Lattice legacy MACH CPLD from Lattice Semiconductor. It is intended for deterministic board-control functions such as wide decoding, state machines, sequencing and interface consolidation. Its nonvolatile configuration is available at power-up, while the full ordering code selects the speed, package, temperature and electrical variant that must match the original design.

The ordering record identifies the device-generation-specific supply family. The -5 token is a speed-grade designator, not a frequency rating by itself. The suffix maps to VC package code. These details determine PCB compatibility, available I/O, timing limits, programming support and environmental suitability; a shared family name alone does not establish drop-in equivalence.

Architecture and Technical Characteristics

This legacy MACH-family device implements combinational and registered equations with product-term logic and programmable routing. Macrocell layout, clock resources, voltage, pinout and programming method vary by generation; the exact full part number and archived design file are required for dependable replacement.

Key Features

• Manufacturer / historical brand: Lattice Semiconductor
• Full part number: MACH111-5VC
• Device classification: Lattice legacy MACH CPLD
• Configuration technology: nonvolatile product-term programmable logic
• Voltage class: device-generation-specific supply family
• Speed-grade designator: -5; use the exact speed-grade AC table for guaranteed timing
• Package / ordering suffix: VC package code; confirm the mechanical drawing and bonded user I/O
• Temperature / qualification: commercial-temperature ordering suffix
• Programming data: verify the exact JEDEC/device algorithm and whether blank or programmed material is required
• User I/O and footprint: confirm the official pin table; package terminals do not equal usable I/O

Applications

• Address decoding, chip-select and bus-control logic
• Reset, power sequencing and board-management state machines
• Interface glue, protocol qualification and deterministic control
• Legacy platform repair and programmed-device replacement
• Compact registered logic, counters and control-path consolidation

Design and Replacement Considerations

Before replacement, compare logic capacity, usable I/O in the selected package, core and I/O rails, input tolerance, output drive, global clock/reset/output-enable resources, power-up state, JTAG or programmer pinout and every guaranteed timing parameter. Preserve the original project, fitter constraints and programming image. Blank programmable logic does not contain the customer function, and a JEDEC file built for a related density, package or voltage derivative must not be assumed compatible. Any migration requires recompilation, pin and timing review, programming verification and functional test on the target board.

Quality & Sourcing

For MACH111-5VC, Antrex Electronics can support stock and lead-time checks, full-suffix confirmation, package and date-code review, photographs, label inspection and shipment planning. Buyers should state the required quantity, acceptable date code, packaging form, target application and whether blank or pre-programmed parts are needed. For discontinued or long-stored programmable devices, appropriate controls can include traceability review, marking comparison, lead or ball-condition inspection, solderability evaluation and third-party electrical or X-ray testing when project risk warrants it. OEMs, EMS providers, repair centers and component buyers may submit BOM lists or hard-to-find programmable-logic requirements for sourcing support.
