M4LV-128/64-18YI

M4LV-128/64-18YI Overview

M4LV-128/64-18YI from Lattice provides a superior Complex Programmable Logic Device (CPLD) solution of user-friendly silicon components and software tools. It also offers an unusually versatile architecture. A proven and predictable CPLD solution, a quicker time to market, more flexibility, and lower costs are the main advantages for users. The MACH 4 devices provide densities between 32 and 256 macrocells with 100% pin-out retention and 100% utilization M4LV-128/64-18YI may operate at 3.3-V (M4LV-x8x) and 5-V (M4 xxx) voltages. Through the JTAG (IEEE Std.1149.1) interface, MACH 4 products can be in-system programmed at 5-V or 3.3-V. Additionally, JTAG boundary scan testing enables device connectivity testing on automated test equipment for products. Every member of M4LV-128/64-18YI offers First-Time-Fit, simple system integration, and pin-out retention following any design change or refit. MACH 4 devices can supply 111 MHz feNT through the assured fixed timing as quickly as 75 ns for both 3.3-V and 5-V operation. When employing up to 20 product terms per output, the SpeedLocking feature is used.

FUNCTIONAL DESCRIPTION

The basic building blocks of M4LV-128/64-18YI are a number of enhanced PAL blocks coupled by a central switch matrix. The center switch matrix directs inputs to the PAL blocks and enables the communication between the PAL blocks. Instead of needing to employ several devices, the logic designer can develop huge designs using just the core switch matrix and PAL blocks. The connecting protocols are crucial for effectively utilizing these devices. The output switch matrix and the logic allocator in the MACH 4 design provide flexible coupling of the macrocells to the product terms and the I/O pins to the macrocells. The input switch matrix also offers extra input routing choices. These resources offer the adaptability required to efficiently fit designs.
