Introduction

7208L20J is a versatile logic device from Samsung Electronics. It is suitable for processing various digital signals in various application fields. It features three built-in 8-bit FIFOs (First-In-First-Out), which offer high-speed operation, guaranteed memory coherence and protection. The device is especially suitable for communications, digital signal processing, motor control and embedded control applications that require fast and reliable FIFO memory.

Features

7208L20J offers several features that make it a reliable logic device. First and foremost, it supports two 16-bit wide interfaces. Furthermore, it offers high-speed operation up to 50MHz, which is the maximum read-write speed of the data bus. Additionally, 7208L20J is equipped with an integrated voltage regulator, providing a high-level of power-saving capability. Lastly, it has three configurable DMA channels for transmitting data.

Applications

7208L20J is a highly configurable logic device suitable for a variety of application fields. It is commonly used in communications, digital signal processing, motor control and embedded control applications. It is particularly useful for applications that require fast, reliable and protected FIFO memory.

Working Principle

The 7208L20J implements a FIFO (first-in-first-out) architecture, which makes the data readable and writeable into the device at a specified rate. The device is designed to store data in an ordered queue and each queue can store up to eight 8-bit words. In addition, the 7208L20J features three configurable DMA channels that can transfer data to other devices or memory locations quickly and accurately. The three distinct DMA channels are Drive, Receive, and State. Finally, the 7208L20J supports two 16-bit wide interfaces which allows it to communicate with other devices or memory locations quickly and reliably. The two wide interfaces are parallel and serial.

Conclusion

7208L20J from Samsung Electronics is a versatile logic device suitable for communications, digital signal processing, motor control, and embedded control applications. It features three built-in 8-bit FIFOs, high-speed operation up to 50MHz, integrated voltage regulator, and three configurable DMA channels for transmitting data. It is an ideal solution for applications requiring fast, reliable and protected FIFO memory.
