M48Z58Y-70MH1E application field and working principle

M48Z58Y-70MH1E is a Zemose Smart Memory family that is designed as a repository for ROM or RAM applications. It is widely used in embedded system design for data storage, firmware identification and set-up, as well as for real-time computing. It is an excellent choice for application programs to support local memory access and memory capacity increase.

Application Field

M48Z58Y-70MH1E memory has a wide application field. It is mainly used in system or consumer designs for product identification, configuration, data logging and battery certified states. It is perfect for multimedia applications such as PDAs, mobile phones, digital cameras, and practical applications such as automotive ECUs. It is also used for consumer design applications such as PCs and electronic payment terminals, remote controllers and game consoles.

Working Principle

The main operation of the M48Z58Y-70MH1E memory is based on a 4-wire serial interface. It allows for a low-cost, low-power and efficient operation. The user can easily access the memory via a standard serial protocol, the SPI bus. It supports cascading and buffering of instructions, making it an efficient solution for memory access and memory capacity increase.

The memory block is organized as 8K-word×8-bit non-volatile (E2) with a self write capability and 256bytes of E2 plus 1Kbyte of SRAM. It also has an auto page read and write capability, allowing multiple pages of data to be read and written in one single command. The M48Z58Y-70MH1E memory can be powered from 4V up to 5.5V and is guaranteed to identify the system power up and the voltage at which it is running. This guarantees fast and reliable system identification.

In addition, the M48Z58Y-70MH1E memory has a write-protect option, which prevents unauthorized access of the memory data during power transition. The write protection is also used to prevent the write operation of the lower 64K bits.

In addition, there is an embedded self-test feature which checks the memory integrity and ensures that there are no unintentional alterations prior to releasing the memory. This prevents data errors due to accidental erasing or overwriting of the memory, reducing the risk of data corruption.
