Working Principle
The MT28EW256ABA1HPC-0SIT is a non-volatile double data rate (DDR) SDRAM. It uses a standard double-data-rate architecture to achieve high bandwidth and features low latency, low power, and extended reliability. The device uses an 8-bit wide bus to access individual bytes of data. The MT28EW256ABA1HPC-0SIT provides synchronous access and transfer of data ~offering simultaneous data input and output control and maximum data throughput. The read/write cycle time is set by the device’s clock frequency which is adjustable up to a maximum of 166MHz.The device can store up to 256Mbits of data which is arranged in two 64Mbit blocks. For reliable operation, the device is organized into four rows and 16 columns. Each row contains 128 bytes of data, and each column contains 16 bytes of data.The device uses error detection and correction (EDC) technology to ensure data integrity. The MT28EW256ABA1HPC-0SIT uses a 8-bit EDC engine to detect and correct data errors, ensuring reliable data transfer. The EDC engine supports multiple levels of ECC which can be configured to meet application-specific requirements.The MT28EW256ABA1HPC-0SIT also features a write-protection mechanism which prevents accidental data corruption during power on and power off cycles. Additionally, the device provides hardware control features such as pre-charge, auto-refresh, auto-power-down and self-refresh modes to reduce power consumption during idle periods.In order to maintain the vital data stored in the device, the MT28EW256ABA1HPC-0SIT offers advanced security features such as a secure erase feature, secure boot, secure erase and JS-IP protection. These features provide strong data protection for sensitive applications, such as military or commercial applications.

Conclusion
The MT28EW256ABA1HPC-0SIT is a high-performance non-volatile double data rate (DDR) SDRAM designed for a wide range of embedded, mission-critical and consumer applications. The device uses a standard double-data-rate architecture for high bandwidth, low latency and low power. Additionally, the device is available in a variety of package sizes and provides a secure erase feature, secure boot, secure erase and JS-IP protection. The MT28EW256ABA1HPC-0SIT is a great choice for applications that require high bandwidth, low latency and non-volatile memory.
