MRAM 4 Click is a compact add-on board representing a magneto-resistive random-access memory solution. This board features the EM064LX, an industrial STT-MRAM persistent memory from Everspin Technologies. It is a 64Mb MRAM IC RAM and can achieve up to 200MHz as a single and double data rate (STR/DTR). The MRAM technology is analog to Flash technology with SRAM-compatible read/write timings (Persistent SRAM, P-SRAM), where data is always non-volatile. It also has a hardware write-protection feature and performs read and write operations with data retention for ten years and unlimited read, write, and erase operations for the supported life of the chip.
We provide a library for the MRAM 4 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for MRAM 4 Click driver.
mram4_cfg_setup
Config Object Initialization function. mram4_init
Initialization function. mram4_default_cfg
Click Default Configuration function. mram4_memory_write
MRAM 4 memory write function. mram4_memory_read
MRAM 4 memory read function. mram4_block_erase
MRAM 4 block erase function. This example demonstrates the use of MRAM 4 Click board. The demo app writes specified data to the memory and reads it back.
The demo application is composed of two sections :
The initialization of SPI module, log UART, and additional pins. After the driver init, the app executes a default configuration.
The demo application writes a desired number of bytes to the memory and then verifies if it is written correctly by reading from the same memory location and displaying the memory content. Results are being sent to the UART Terminal, where you can track their changes.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
