Memory

M48Z35Y-70MH1E semiconductor memory is a non-volatile Static Random Access Memory (SRAM), providing a simple, efficient and inexpensive solution for static memory applications. It is a high-performance, low-power, extremely reliable product that operates from a single +5V supply.

The M48Z35Y-70MH1E memory active area consists of 18,360-bit static RAM memory array. A convenient, user-friendly and simple command list sequence provides a fast, powerful and flexible way to manage the memory and read/write operations.

The M48Z35Y-70MH1E is an ideal replacement for EEPROMs and hard disk drives, particularly in applications where byte-level or byte/word data transfer is crucial. Its nonvolatile memory configuration allows data to remain stored even during system power-down. Memory access times are measured in microseconds, providing maximum system throughput.

The internal organization of the M48Z35Y-70MH1E is an array of 18,360 words. Each word is 32 bits in length and uses a single +5V power supply. Addressing and read/write operations for each word is accomplished via a serial address register and external control signals. The serial port is compatible with both serial and parallel interfaces. Data is transferred serially with eight control signals plus a data control signal and an address control signal.

The M48Z35Y-70MH1E features low power consumption and a low thermal profile that consumes less than 10 mW of power, resulting in fewer device related failures and reliable performance. The device\'s data retention range is between -55 and +125 °C, ensuring long-term data integrity.

The maximum data transfer rate of the M48Z35Y-70MH1E is 70-Mbps, making it ideal for applications where data rate is a major concern. The internal architecture supports an asynchronous write and data transfer protocol, allowing the device to transfer data quickly and effectively in multiple directions.

The functional design of the M48Z35Y-70MH1E enables efficient operation compared to volatile memory. The nonvolatile memory array is partitioned into two parts, with one part used for user-defined tasks and the other for data storage. User-defined tasks are called soft functions, which are defined software functions that are executed from the internal registers during specific commands to perform specific operations. The soft function code is stored in the memory array and has the ability to modify settings and perform specific tasks in response to external commands.

In addition to its advanced memory features and easy-to-use serial command list sequence, the M48Z35Y-70MH1E also features a CRC (cyclic redundancy check) error detection scheme to ensure data integrity in applications handling user data. The CRC error checking scheme performs a series of checksum calculations to detect any error within the system, making sure that only valid data is processed.

M48Z35Y-70MH1E is ideal for high-performance, yet low-power applications, such as automotive, industrial automation, medical electronics and consumer electronics applications. The device also offers security features to help protect user data for a wide range of applications. As a highly reliable and efficient memory solution, the M48Z35Y-70MH1E is designed to offer superior data retention in battery-backed systems.
