M5LV-256/74-7VI

CPLDs, or Complex Programmable Logic Devices, are integrated circuits that possess two distinct characteristics: they can implement combinatorial and sequential logic functions and they can be re-programmed quickly and cheaply. The M5LV-256/74-7VI is a CPLD developed by Altera corporation designed with a combination of embedded logic and RAM blocks that help users to quickly implement complex logic designs. The device is based on a 90 nm MAX II architecture, and it is one of the most compact CPLD devices in the market. It is ideal for applications that require fast performance and cost-effective design.

Application Field of M5LV-256/74-7VI

The M5LV-256/74-7VI is suited to a range of applications in different markets, including consumer, automotive, industrial and aerospace. It is designed as a secure device with features that include temporal decoupling and locking of secure data. It also features an ID code and authentication key to help protect system data from counterfeits. Other applications of this CPLD include the design of cost-effective PLD designs for smart cards, RFID tags and controllers, personal electronics and consumer audio systems.

Working Principle of M5LV-256/74-7VI

The M5LV-256/74-7VI CPLD is based on a single-chip MAX II architecture. It contains a maximum of 256 logic elements, which are 10-input look-up table (LUT)-based logic elements that implement universal logic functions. This device also features three dedicated multipliers and seven block RAM elements, which feature 4-bit words. These blocks can be used to implement various types of sequential and combinatorial logic circuits. Additionally, the M5LV-256/74-7VI has two global clock buffers, which can be used to implement various types of high-performance logic designs. Altogether, all these features enable users to design complex, feature-rich and cost-efficient PLD designs.

The M5LV-256/74-7VI CPLD can be programmed in two different ways: in-system and via an EPROM programmer. In-system programming requires the use of an Altera programmer and the corresponding software, while an EPROM programmer can be used for optimal programming performance and reliability. Either way, the device can be re-programmed quickly and at low cost, making it a great choice for applications that need to be modified or upgraded frequently.

Conclusion

The M5LV-256/74-7VI is a powerful, feature-rich and cost-effective CPLD from Altera Corporation. It has a range of applications, including consumer, automotive, industrial, and aerospace. Additionally, the device can be programmed in-system or via an EPROM programmer, allowing users the flexibility to modify or upgrade their PLD designs quickly and cheaply. This device is sure to meet the needs of any complex logic design or high-performance controller application.
