Overview
The EPM5064LC-1 is a member of Altera's MAX 5000 series of programmable logic devices. These PLDs offer a flexible solution for implementing custom digital logic without the need for custom ASIC development. The device is particularly useful for prototyping and small-to-medium production runs where flexibility is paramount. The EPM5064LC-1 features 64 macrocells, providing sufficient capacity for many common digital logic applications. It operates at 5V and is fabricated using CMOS technology, offering a good balance between performance and power consumption.
Structure and Working Principle
The EPM5064LC-1 consists of a programmable AND array and fixed OR array architecture. The device can be programmed using hardware description languages or schematic entry through Altera's development tools. Once programmed, the device implements the desired logic functions by configuring its internal interconnections. The device operates by receiving input signals, processing them through the programmed logic array, and producing the corresponding output signals. This allows for the implementation of complex combinational and sequential logic circuits in a single chip.
Key Features
The EPM5064LC-1 offers several notable features including 64 macrocells, 5V operation, and typical propagation delays of 7.5ns. The device supports in-system programmability, allowing for field updates of the logic configuration. Additional features include a security bit to prevent unauthorized copying of the configuration, power-saving modes, and compatibility with standard TTL logic levels. The device's architecture is particularly well-suited for state machine implementations and medium-complexity glue logic applications.
Application Areas
The EPM5064LC-1 finds application in various digital systems including industrial control systems, telecommunications equipment, and computer peripherals. It's commonly used for implementing interface logic, bus arbitration, and simple state machines. In embedded systems, the device often serves as a bridge between different logic families or as a means to consolidate multiple discrete logic components into a single programmable solution. Its reprogrammability makes it particularly valuable during product development phases.
Maintenance and Precautions
When working with the EPM5064LC-1, proper ESD precautions must be observed at all times. The device should be handled with grounded wrist straps and stored in anti-static packaging when not in use. Power supply pins require proper decoupling with capacitors placed close to the device. During programming, ensure the programming voltage is stable and within specified limits. The device has a limited number of programming cycles (typically 100-1000), so frequent reprogramming should be avoided in production environments.
B2B Procurement Guide
When procuring EPM5064LC-1 devices, verify the manufacturer's part number and package type (LC indicates a leaded package). Consider ordering samples for testing before committing to large quantities. Check for RoHS compliance if required for your application. For production quantities, establish relationships with authorized distributors to ensure genuine components. Lead times may vary, so plan procurement accordingly. Consider alternative PLDs in the same family if availability becomes an issue, but verify pin and feature compatibility.
