PAL20R6-12/BLA

Programmable Logic Device Pld Overview

The PAL20R6-12/BLA is a Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It belongs to the PAL20R6 family, featuring a 20-pin PLCC package and TTL-compatible inputs. The component operates with a maximum propagation delay of 12 ns and supports a maximum clock frequency of 83 MHz. It includes 10 input lines, 6 registered outputs, and 4 dedicated inputs. The device utilizes a plastic LCC-20 package and incorporates features such as power-up reset and register preload for enhanced testability and initialization.

Programmable Logic Device Pld Feature Summary

• TTL-compatible logic with 10 inputs and 6 registered outputs
• Maximum propagation delay of 12 ns
• Power-up reset and register preload capabilities
• 20-pin Plastic Leaded Chip Carrier (PLCC) package

Programmable Logic Device Pld Applications

• High-performance digital logic control systems
• State machine implementations requiring registered outputs
• Interface logic in TTL-based computer architectures

Programmable Logic Device Pld Part Context

This component is part of the AMD PAL20R6 series, designed for complex logic replacement in high-speed applications. The '12' suffix indicates the speed grade with a 12 ns delay, while '/BLA' typically denotes specific packaging or environmental compliance variations within the manufacturer's lineup. It serves as a fixed-function logic substitute in legacy designs.

Programmable Logic Device Pld Replacement Considerations

Direct replacements must match the PAL20R6 architecture, 20-pin PLCC package, and 12 ns speed grade. Verify that substitute devices support TTL input levels and registered output configurations. Cross-reference with AMD/AMD-compatible PLD families ensuring identical pinout and logical functionality.
