Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Excelon™-Ultra CY15V102QSN is a high-performance 2 Mbit non-volatile memory with an advanced ferroelectric process. Ferroelectric random access memory (i.e. F-RAM) is the same as RAM, a volatile memory that performs read and write operations. It offers 151 years of reliable data retention and solves the complexity, overhead and system-level reliability problems caused by serial flash and other non-volatile memories. 

Unlike serial flash, the CY15V102QSN performs write operations at bus speed. The CY15V102QSN performs write operations at bus speed and does not cause delays in write operations. After each byte has been successfully transferred to the device, the data is immediately written to the memory array. At this point, the next bus cycle can be started without polling the data. In addition, this product offers a higher number of erasures than other non-volatile memories. The CY15V102QSN is capable of providing 1014 read/write cycles or supporting 100 million more write cycles than the EEPROM. Because of these features, the CY15x104QSN is ideal for non-volatile memory applications that require frequent or fast write operations. Examples range from data collection, where the number of write cycles is very important, to meeting industrial grade control, where the long write times of serial Flash can cause data loss. 

The CY15V102QSN combines 2 Mbit F-RAM with a high speed quad SPI (QPI) SDR and DDR interface to enhance the non-volatile write capability of F-RAM technology. The device contains a read-only device ID and a unique ID feature that allows the SPI bus master to determine the manufacturer, product capacity, product version and unique ID of the device. 

The device supports on-chip ECC logic to detect and correct single-bit errors within each 8-byte data cell. The device also includes an extension to provide double-bit error reporting in the 8-byte data cell. The CY15V102QSN also supports Cyclic Redundancy Check (CRC), which can be used to verify the integrity of the data stored in the memory array.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
