AT28C256-15DM/883

The AT28C256-15DM/883 is a type of memory integrated circuit (IC) chip designed for high-performance applications. It is manufactured by Atmel, a semiconductor manufacturer based in California, USA. It is based on the industry standard 28C-series memory chips and is one of the most efficient in the market. It is widely used in a variety of applications, including aerospace, automotive, medical, gaming, computing and embedded systems.

The AT28C256-15DM/883 is a 25-pin memory IC chip that features 32K×8-Bit of organized fixed-electrically erasable programmable memory (OTP-EEPROM). The chip combines the low power operation and fast-write characteristics of OTP-EEPROM devices with non volatile storage. Its fast access time allows devices to be programmed and erased quickly, while still operating at low power levels. The AT28C256-15DM/883 is suitable for a range of applications, including data logging, digital signal processing, instrumentation, medical electronics and portable devices.

The working principle of the AT28C256-15DM/883 involves transferring information between a programmed memory location and a non-volatile storage medium. Data is written to the programmed memory location in a microcontroller or processor, and then transferred to the non-volatile storage medium in order to be preserved. To read the stored data back from the non-volatile medium, the processor or microcontroller issues a read voltage to the AT28C256-15DM/883, which then transfers the data from the non-volatile medium to the programmed memory location. Once data is written to the non-volatile medium, the microcontroller or processor can erase and reprogram the AT28C256-15DM/883 as needed.

In addition to transferring data, the AT28C256-15DM/883 offers a range of additional features, including powerful write and erase operations, on-chip write protect circuitry and self-timed programming. The write and erase operations allow users to control the information stored in the device, while the write protect circuitry ensures that the stored data remains secure. Furthermore, the self-timed programming feature ensures that the device can accurately write data to and from the non-volatile medium, although this must be done with reference to the device’s specifications.

Applications of the AT28C256-15DM/883 include aerospace, automotive, medical, gaming, computing and embedded systems. It is suitable for use in applications where low power, fast write and erase operations, and reliable data storage are required. The device can also be used for data logging, digital signal processing, instrumentation, medical electronics, and portable devices.

In conclusion, the AT28C256-15DM/883 is a suitable memory IC for a variety of applications that demand reliable and fast data storage, as well as low power consumption. It offers a range of features, including powerful write and erase operations, on-chip write protect circuitry and self-timed programming, which make it suitable for many high performance applications.
