Logic memories cover a wide range of storage and computing applications. Among these memories are FIFOs, which are fast intermittent memories used for quick sequential data storage and retrieval. The 72V821L10PF is a recently developed FIFO memory integrated circuit specifically designed for automotive and industrial applications. This article discusses the application fields and working principle of the 72V821L10PF.

Application Fields

The 72V821L10PF integrated circuit is specifically designed to meet the demands of the automotive and industrial applications, allowing the designers to increase system performance while maintaining compatibility with the legacy components. It is capable of providing high throughput rates in low voltage environment, and its low power consumption makes it ideal for battery operated devices.

The 72V821L10PF is compatible with various standard industry interfaces, such as JTAG, CAN bus, and I2C bus, which allows it to be used in a variety of applications, ranging from automotive infotainment systems to factory automation. It is also equipped with multiple power options, including single- and dual-supply voltage, making it suitable for wide range of applications.

In addition, the 72V821L10PF features multiple diagnostic features, such as ECC (error-correcting codes) and partial-word write information protection, allowing designers to diagnose system malfunctions quickly and easily.

Working Principle

The 72V821L10PF is a full-duplex, non-volatile FIFO memory integrated circuit. It is composed of a static RAM-based memory array, and utilizes an efficient synchronous write/read circuitry for organizing data in First-In/First-Out (FIFO) queues. Data is read from or written to the memory array via a 32-bit wide parallel interface.

When a write request is received, the data is written to the memory buffer, and is subsequently organized into a FIFO queue by the associated stored control signals. When a read request is received, the stored control signals are used to retrieve the data from the FIFO queue. The data is then retrieved in address sequence and is presented to the external bus as 32-bit wide parallel words.

The 72V821L10PF is capable of storing up to 65535 words of 32-bit data at a time, with each word being stored in its own region of the memory array. It is also capable of operating at high throughput rates, up to 32Mbit per second, allowing it to process data quickly and efficiently.

In addition, the 72V821L10PF is equipped with an integral ECC mechanism to help detection and correction of single bit errors in the data stored in its memory array. The ECC mechanism works by generating a code from the stored data bits and comparing it to the stored control signals. If the two codes don\'t match, the data is flagged as being corrupted and the ECC mechanism takes action to correct the errors.

Conclusion

The 72V821L10PF is a recently developed FIFO memory integrated circuit designed for automotive and industrial applications. It is capable of providing high throughput rates in low voltage environment, and features multiple diagnostic features, such as ECC and partial-word write information protection. Its low power consumption makes it ideal for battery operated devices, and it is equipped with multiple power options, allowing it to be used in a variety of applications, ranging from automotive infotainment systems to factory automation.
