GAL16V8Z-15QJ – LATTICE SEMI

Overview

The Lattice Semiconductor GAL16V8Z-15QJ is a versatile, 8-macrocell Complex Programmable Logic Device (CPLD) designed for general-purpose logic implementation with a maximum propagation delay of 15ns. Its key strength lies in its reprogrammability, allowing for design iteration and bug fixing in the field, a significant advantage over mask ROM-based devices. However, engineers must carefully consider the trade-off between its flexibility and the inherent latency introduced by the programmable interconnect matrix, which can impact timing-critical applications requiring sub-10ns response times.

Key Features

• 8 Macrocells
• 15ns Propagation Delay
• 20-PLCC (9×9) Surface Mount Package
• EEPROM-based Reprogrammability
• Low Power Consumption (typical standby current)
• Configurable Input/Output Pins

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Address decoding and bus arbitration in embedded systems
• State machine implementation for control logic
• Glue logic for interfacing disparate digital modules
• Simple sequential circuit design and prototyping
