SN74ACT3631-30PQ

Logic-FIFOs Memory have many applications in communication, computer, control and other systems. This article will explain an advanced type of FIFOs Memory: SN74ACT3631-30PQ, its application field and working principle.

As an advanced mixed-signal FIFO (First In First Out) memory component, SN74ACT3631-30PQ offers features that are unavailable in parallel FIFOs, such as more varied control signals, watchdog timeout capabilities, single-side flag control when there is only a single control line, and internal looping. In addition, it also offers a very low power operation with a maximum power dissipation of only 720mW, making it desirable in battery-powered or otherwise power-sensitive applications.

SN74ACT3631-30PQ can be applied in almost any system as it could receive and transmit digital data. An example is its most commonly found use in network bridge applications, where it can be connected between slow devices and a communication interface. On receiving data, SN74ACT3631-30PQ first examines it and then stores it in its internal FIFO Buffer. After a certain amount of data are stored, it passes the data to the destination device at a predetermined speed.

The internal architecture of SN74ACT3631-30PQ mainly contains a pair of FIFO memories of 512x9 bit FIFO memories, a 512x14 bit FIFO logic, a timeout logic and an SPI interface logic. It has two flag pins Trigger and Flag which can be used as an indicator when data is filled up or emptied of the FIFO memories and when there is an error occurs. Also, it has active-LOW Write and Read inputs to control the transfer data between the FIFO memories and the SPI interface.

The SN74ACT3631-30PQ operates with a voltage supply from 4.75V to 5.25V. The write and read operation can be done from outside via its serial interface. It guarantees a high data rate and are available in two different processes: the slower process for commercial and automotive (up to 20MHz) and the faster process for industrial applications (up to 80MHz). It is built with a CMOS process which allows for a very low static current, an operating temperature range from -40°C to +125°C and a non-volatile memory.

In conclusion, SN74ACT3631-30PQ is a advanced FIFOs Memory with many features and wide application fields. Its persistent memory allows it to store and transfer data between different devices. In addition, its low power dissipation makes it suitable for battery-powered systems. With its high data rate and its low price, it is an ideal solution for many communication applications.
