The M95320-DRDW3TP/K is an ultralow-voltage voltage-only Serial Peripheral Interface (SPI) ferroelectric random access memory (F-RAM) device. It offers a huge density that ranges from 8K to 8M bits and along with the same low-voltage operation as the M95320, such as a typical read/write supply voltage of 3.0V or lower. This device is the best storage solution for memory designs that require high density, fast access time, simple peripheral interface, extended data retention and low power consumption. It is an ideal device to store critical information that requires ruggedness and reliability.

The M95320-DRDW3TP/K memory has a variety of application fields. It is widely used in embedded systems, real-time computing and industrial/automotive control systems. All these applications require a fast, reliable and low power memory device. Since the device features a fast data write and read cycle of 1.5, 6 and 15 mS and a wide temperature range, it is an ideal device for such applications.

The M95320-DRDW3TP/K memory also features a write protect pin which prevents accidental data erasure. The pin can be set through a simple logic operation. Moreover, the device is extremely low power and consumes only 10uA active current, making it an ideal device for portable and battery-operated applications. The device also features a self-refresh capability, which keeps it ready for usage even when the power supply is interrupted. The device also has an extended data retention of greater than 20 years, making it a long-term reliable device.

The M95320-DRDW3TP/K memory works using the Serial Peripheral Interface (SPI) protocol. The protocol is a synchronous data transmission protocol that operates between two or more devices over two lines namely, clock line (SCK) and a serial port (MOSI). The SCK line provides a synchronous clocking signal to control the rate at which data is transmitted. The MOSI line transmits the data to the device. The read and write operations use a combination of the Serial Peripheral Interface and an integrated Charge Pump System to perform the operations. For example, to write data to the device, the write enable command is sent over the Clock and MOSI lines, followed by the data to be programmed. The write operation is then performed and the device then sends the status byte of the write operation to the host processor.

The M95320-DRDW3TP/K is thus an ideal device for storing small amounts of critical data reliably and easily. The device is reliable, rugged and suitable for a wide range of applications, including embedded systems, real-time computing, industrial/automotive control systems and portable/battery operated systems. It also has fast programming and data input time and has an extended data retention.
