The IS25WP128F-JKLE-TR is a part of memory devices. It is a 4Mbit (512Kb x8) Serial flash memory that features the industry’s highest (1Mbit/s) Serial Peripheral Interface (SPI) clock rate. The device has an output I/O power supply of 2.7V to 3.6V, which makes it ideal for battery-powered applications.

The IS25WP128F-JKLE-TR comprises of a parallelly mounted 8-bit non volatile memory a SPI bus compatible 8-bit microcontroller and a 4M bit Flash Memory. The 4M bit Flash Memory stores user data, while the 8-bit microcontroller transfers the data to and from the Flash memory. The 8-bit microcontroller is mainly responsible for initialization, setting the write/read addresses, writing/reading user data, erasing sectors, suspending/resuming Erase/Write operations, providing protection against accidental/malicious write/read operations, setting lock bits, and responding to the status of Erase/Write operations.

The IS25WP128F-JKLE-TR Serial Flash works in two modes; the Single-SPI mode, and the Dual-SPI mode. The Single-SPI mode allows the device to communicate with the processor at which the Flash is connected in a master-slave mode. The Dual-SPI mode allows the Flash memory to operate in multiple modes, such as high speed Quad-SPI and Dual I/O-SPI mode, offering even higher performance.

The Quad-SPI mode is characterized by the use of four basic transfer protocols; Single, Dual, Quad, and QPI. These protocols are used to facilitate faster data transfers. The Single transfer protocol initiates one read/write cycle that is sent and received by the Microcontroller in the device. The Dual transfer protocol initiates two independent read/write cycles over the four serial lines, while the Quad transfer protocol initiates four independent read/write cycles over the four serial lines. The QPI (Quad Peripheral Interface) transfers four unique instructions simultaneously over a single SPI write cycle, thereby eliminating the need for separate SPI read/write cycles.

The IS25WP128F-JKLE-TR is either packaged in a WSON 8(8x6mm) or a TFBGA 8(8x6mm) package. It is available in two speeds; a commercial speed of 66MHz and an extended speed of 104MHz. Both of these speeds support all SPI protocols.

The IS25WP128F-JKLE-TR is produced using 1z Logic’s advanced 65nm NVM process. 1z Logic is a leading semiconductor company that specializes in NVM technologies. The device offers several advantages such as low voltage operation, robust ECC, high speed and reliable data storage.

In conclusion, the IS25WP128F-JKLE-TR is an ideal memory device for applications that require fast communication and high reliability. The device is available in two speeds, has advanced NVM process and offers various advantages, such as low voltage operation, robust ECC, high speed and reliable data storage.
