M93S56-WMN6P is a non-volatile 8k-bits serial SPI memory device manufactured by STMicroelectronics. It operates from voltage sources between 2.3 and 3.6V, with a standby mode conserving power consumption. It provides 8bits of data, with a maximum clock speed of 20MHz. The memory is organized into 512 pages of 16 bytes, although the actual number of memory locations is higher due to the ability to access individual bytes within the page. The device also has write protection including block, sector, password and software protection. Overall, the M93S56 is designed to be a reliable and low-cost memory solution.
