Now bring 256K of fast additional memory to your design with FRAM click. This add-on storage board features a Fujitsu MB85RS256A IC, which is a 256K FRAM (Ferroelectric Random Access Memory) module. The MB85RS256A module employs the ferroelectric process and silicon gate CMOS technologies to form the non-volatile memory cells. Being non-volatile, it is capable of retaining data without requiring a back-up battery, unlike SRAM. In addition, FRAM click can also provide high-speed write operation and can be used for up to 10 billion read/write operations. FRAM click uses the mikroBUS SPI (MISO, MOSI, SCK, CS), RST and PWM lines to communicate with the target board. The maximum SPI operating frequency is 25 MHz. The board is designed to use 3.3V power supply only.

The FRAM Click Board is an ideal option for the log management and the storage of the resume data, etc.

IC/Module: MB85RS256A 32768 x 8bit FRAM Memory Chip

MB85RS256A is a 256K bit FRAM LSI in a in a configuration of 32,768 words × 8 bits. Using SPI communication interface, this 256K FRAM Memory Chip uses the ferroelectric process and silicon gate CMOS technologies to form the non-volatile memory cells. This superior non-volatile FRAM offers fast access (like RAM) and is able to retain data without using a back-up battery.

Speed and High Endurance

FRAM offers 30x faster writes per second as compared to EEPROM or Flash memories. MB85RS256A does not take long time to write data unlike Flash memories or EEPROM, and takes no wait time. The non-volatile memory cells can be used for 10 billion read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and EEPROM.

Additional Useful Pins

FRAM click board also includes two functional pins: hold (HOLD) and write protect (WP). The HOLD pin is used to interrupt serial I/O without de-selecting the chip. The WP (write protect) pin is used to control writing to a status register.
