MIKROE-2914 MRAM click Board™

MikroElektronika's MIKROE-2914 add-on board featuring the MRAM module from Everspin Technologies

Image of MikroElektronika's MIKROE-2914 MRAM Click™ BoardThe MIKROE-2914 MRAM click board from MikroElektronika uses the MR25H256, a 256 kilobit serial SPI MRAM memory module from Everspin Technologies. This module contains 262,144 bits of memory that can be randomly accessed. The pinout memory module is similar to the most commonly used EEPROM modules making them direct replacements. The usual SPI lines, SO, SI, SCK, and #CS pins from the MR25H256 IC, are routed to the mikroBUS™ SPI port (MISO, MOSI, SCK, and CS pins). Besides the SPI serial bus, there are two more pins routed to the mikroBUS.

MRAM click features MRAM module which contains 262,144 magneto resistive memory cells, organized into 32,768 bytes of memory. The MIKROE-2914 MRAM click board is a memory storage device with 32 KB of memory space. The used memory module can withstand an unlimited number of write cycles, it has data retention period greater than 20 years, and it can read and write to random addresses with no delay. Besides these features that already mark this kind of memory module, a milestone in memory manufacturing technology, the device features data protection in case of power loss, block write protection, low power consumption, and fast SPI interface that can theoretically work up to 40 MHz. Because of its universal memory characteristics, MRAM click can be used both as a non-volatile storage media or temporary RAM expansion for storing variables in any embedded application.
