LC4128V-10TN144I

Complex Programmable Logic Devices Overview

The LC4128V-10TN144I is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000V family, manufactured by Lattice Semiconductor. It features 128 macrocells organized into 8 logic array blocks and provides 96 input/output pins. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports system-in-programmability. It is housed in a 144-pin Thin Quad Flat Package with a maximum propagation delay of 10 ns.

Complex Programmable Logic Devices Feature Summary

• Supports system-in-programmability for flexible design updates
• High-density architecture with 128 macrocells and 96 I/Os
• Compatible with standard 3.3 V power domains

Complex Programmable Logic Devices Applications

• General-purpose digital logic implementation
• Bus bridging and protocol conversion
• Address decoding and control logic in embedded systems

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +105°C) and 'TN144' denotes the 144-pin TQFP package. Confirm that the 'V' series designation aligns with current manufacturing specifications, as product lines may undergo obsolescence or revision notices. Ensure compatibility with existing PCB footprints for the 20x20 mm package outline.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with high pin count is required for legacy or cost-sensitive designs. Compare against the LC4128V-75 variant if faster switching speeds (7.5 ns) are necessary. Consider the broader ispMACH 4000V family for alternative package options or different speed grades while maintaining the same 128-macrocell architecture.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, which offers non-volatile configuration memory allowing instant-on functionality. The family is designed for applications requiring reliable, low-power programmable logic with support for various I/O standards. It serves as a drop-in replacement for older GAL devices in many industrial and consumer applications.

Complex Programmable Logic Devices Replacement Considerations

The LC4128V-75TN144I is a confirmed substitute offering identical pinout and logic resources with improved timing performance. Verify that the application timing constraints allow for the slower 10 ns delay of the LC4128V-10 variant if upgrading from the -75 grade.
