EPM7128SLC84-15 – ALTERA

Overview

The Altera EPM7128SLC84-15 is a high-performance Complex Programmable Logic Device (CPLD) designed for intricate combinatorial and sequential logic functions, boasting 128 macrocells and a maximum propagation delay of 15 ns. Its core strength lies in its dense logic fabric and predictable timing, making it suitable for state machine implementation and address decoding. However, designers must carefully consider the trade-off between its generous macrocell count and the inherent pin limitations of the 84-PLCC package, which can necessitate careful I/O planning and potentially external buffers for complex designs.
