Working Principle

The IDT7202LA25SOI8 FIFO is a logic device that provides a single-clocked, high-speed FIFO memory solution.This device supports an asynchronous and synchronous data transfer , which is a low-cost and fast way of storing data in a memory device.The device is capable of storing a 25-bit wide data word, which is composed of two 5-bit read pointers, two 7-bit write pointers, and one 2-bit status field.The data words are stored in a memory array and can be transferred from the device to a bus or from the bus to the device in either direction.The bus used is typically the peripheral bus, such as the I2C or SPI bus.

The device uses the clock signal to control data movement between the read and write ports.The data movement is controlled by the READ EN, WRITE EN, and RESET signals.The READ EN signal enables the data to be read from the device and the WRITE EN signal enables the data to be written to the device.The RESET signal sets all the registers in the device to a blank state.All these signals are set to a logic high level when the device is enabled and when it is not enabled a logic low level is output.

The device operates in either FIFO or LIFO(Last In First Out)mode.In FIFO mode the oldest data word is read first and in LIFO mode the most recently written data word is read first.The FIFO depth is determined by the number of words that can be stored in the memory array.The device supports an addressable memory space and features a combination of status and write/read pointers which enable the user to track the position and data in the FIFO.The device also offers a low-power sleep mode and supports programmable FIFO underflow/overflow conditions.

The IDT7202LA25SOI8 supporting continuous read and write operations.The device supports two write modes for the asynchronous data transfer: a level-sensitive write mode and a pulse-backed write mode.The device also supports two read modes for the synchronous data transfer: a readback mode and a two-phase read mode.In the readback mode the device will provide the data stored in the memory to the bus and in the two-phase read mode it will provide a single data packet at a time.The device supports error correction and control codes in order to detect any possible data errors.

The IDT7202LA25SOI8 FIFO logic device offers unmatched flexibility and performance in a variety of applications.It offers fast, reliable operation and features a wide-range of operating frequencies.It provides a robust, low-profile memory solution and supports continuous read and write operations.It also supports error correction and control codes in order to detect any possible data errors.
