How Does The EEPROM 9 Click Board™ Work?
The EEPROM 9 Click Board™ is based on the M95P32-I, a 32Mbit SPI page EEPROM device from STMicroelectronics, divided into 8192 erasable pages of 512 bytes (organized either as 1024 erasable sectors of 4 Kbytes, 64 erasable blocks of 64 Kbytes or as an entirely erasable array). The M95P32-I is manufactured with ST's advanced proprietary NVM technology and offers byte flexibility, page alterability, high page cycling performance, and ultra-low power consumption. It is highly reliable, lasting 500k write cycles with 100 years of data retention (10 years after 500k cycles), which makes it suitable for various applications where dependable nonvolatile memory storage is essential.
This Click board™ communicates with MCU using the SPI serial interface that supports the two most common modes, SPI Mode 0 and 3, with a maximum SPI frequency of 80MHz. As mentioned, the M95P32-I offers byte and page write instructions of up to 512 bytes. Write instructions consist of self-timed auto-erase and program operations, resulting in flexible data byte management. It also accepts page/block/sector/chip erase commands to set the memory to an erased state. The memory can then be fast-programmed by pages of 512 bytes and further optimized using the "page program with buffer load" to hide the SPI communication latency. Additional status, configuration, and volatile registers set the desired device configuration, while the safety register gives device status information
In addition to the SPI communication, the EEPROM 9 Click has two additional pins used for Write Protection and Communication Hold function routed to the WP and HLD pins of the mikroBUS™ socket. The HLD pin of the mikroBUS™ socket can be used to pause the serial communication with the M95P32-I without deselecting the device. The configurable Write Protection function routed to the WP pin of the mikroBUS™ socket allows the user to freeze the memory area protected against Write instructions in a read-only mode (as specified by the values in the BPx and TB bits of the STATUS register).
The EEPROM 9 Click Board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
