M5LV-128/68-12VI

Complex Programmable Logic Devices Overview

The M5LV-128/68-12VI is a low-voltage Complex Programmable Logic Device (CPLD) from the Lattice MACH 5 family. It operates at 3.3 V and contains 128 macrocells with 68 user I/O pins. The device features a maximum propagation delay of 12 ns and supports a maximum count frequency of 182 MHz. Manufactured using E²CMOS technology, it includes IEEE 1149.1 boundary scan compliance for testing and in-system programming. The component utilizes a hierarchical architecture with multiple switch matrices to ensure 100% routability and pin-out retention across density upgrades.

Complex Programmable Logic Devices Procurement Notes

Verify product status before procurement as select devices in the MACH 5 family have been discontinued. Confirm that the specific ordering suffix matches the required voltage and speed grade specifications. Ensure design compatibility with the 3.3-V supply requirements and check for availability through authorized distributors or legacy stock channels.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells with 68 I/Os at a 12 ns speed grade. The M5LV designation indicates 3.3-V operation, suitable for mixed-voltage systems where inputs tolerate up to 5.5 V. Consider the -12 speed grade if the system timing requires delays within 12 ns while maintaining PCI Local Bus Specification compliance.

Complex Programmable Logic Devices Part Context

This component belongs to the MACH 5 CPLD family, which offers densities ranging from 128 to 512 macrocells. The M5LV series specifically denotes 3.3-V devices, distinct from the 5-V M5 series. The family shares a consistent fifth-generation MACH architecture, allowing designers to migrate between different density and I/O options within the same package footprint without redesigning the board layout.

Complex Programmable Logic Devices Replacement Considerations

For equivalent performance, consider other M5LV-128 variants with different speed grades (e.g., -5, -6, -7, -10) or I/O counts (e.g., -74). Devices sharing the same package but differing in macrocell density may require pinout verification.
