M5LV-256/74-7VI

Complex Programmable Logic Devices Overview

The M5LV-256/74-7VI is a 3.3-V Complex Programmable Logic Device (CPLD) from the Lattice MACH 5 family, featuring 256 macrocells and 104 user I/O pins in a 144-pin TQFP package. It operates within a supply voltage range of 3.0 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C. The device achieves a maximum propagation delay (tpd) of 7.5 ns and a counter frequency (fcnt) of 182 MHz. Key architectural features include IEEE 1149.1 boundary scan compliance, in-system programmability via JTAG, and support for mixed-voltage system designs with 5-V tolerant inputs.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and speed grade. Check for RoHS compliance status as indicated in official documentation, noting that older revisions may not meet current environmental standards.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells and 104 I/Os are required in a 144-pin surface-mount package. Ensure the design utilizes a 3.3-V core voltage while accommodating 5-V tolerant I/Os if interfacing with legacy components. Verify that the 7.5 ns timing meets the system's clock requirements and that industrial temperature ratings (-40°C to +85°C) align with the operating environment.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice MACH 5 CPLD family, which offers hierarchical architecture with 100% routability. The M5LV series specifically denotes 3.3-V operation, contrasting with the 5-V M5 series. The '7' in the suffix indicates the 7.5 ns speed grade, suitable for PCI-compliant designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same density and package should be sought from the M5LV-256 series. Consider upgrading to modern Lattice FPGA families for enhanced security and lower power consumption if available inventory permits.
