Memory:

IS62WV5128EBLL-45BLI is a cellular SRAM device that belongs to the NOR Flash memory family. It is a high-speed, low-power memory device from ISSI. This device combines the fast random access of SRAM with the low-power operation of an applications processor.

The IS62WV5128EBLL-45BLI has various applications in automotive, industrial, medical, and consumer markets. It is commonly used for image storage, data buffering, error correction, and firmware updates. This device is highly suited for real-time data processing, as its read and write cycle time is much faster than traditional SRAM using the same power.

Working Principle:

The IS62WV5128EBLL-45BLI operates in a serial access, 8-bit data bus mode. Data are transferred by a synchronous serial port (SSP) that is controlled by a clock. This device can operate up to 70MHz in the default mode, but can be extended to reach 106MHz in the extended mode. Data is stored in a flat array of 256 K words, organized as 512 V pages. The device has an element security feature that provides improved key management, increased access control and a secure data path between the device and the processor.

During write operations, the device accepts 8-bit data from a processor for each byte. These data are internally latched into the word register and stored in the 512 V pages. During the read operation, the data present in the word register are read out sequentially in 8-bit chunks. The data with the correct layout is then provided to the processor.

The device is accessed via the SSP for fast read, write and erase operations. Data written to the device is secured and can be over-written or erased when desired. The device also provides an in-memory erase capability to erase data from individual cells. The device also provides error correction coding capability to ensure the data is accurately written and read.

The IS62WV5128EBLL-45BLI is a low-power and high-speed device that provides a vast array of applications. Its fast-read and write times, in combination with its security features, make it well suited for applications that require fast, data-intensive operations. The devices are available in a variety of packages, and can provide the most demanding users with all the features and performance they could ask for.
