Memory The AT27C4096-55PI is a high-density, dynamically erasable and programmable read only memory (EEPROM) device. It offers a wide range of advantages over conventional, specialized memory products. The device’s low-power operation, random read/write capability, and its wide operating voltage range make it an ideal solution for a number of different applications. The device is comprised of 4,096 words, each containing 16 bits of information. Data is stored in the device in a non-volatile manner and only becomes prone to change when the user specifically requests it to be changed. The power required for operations ranging from reading, writing and erasing data is quite low and varies with the step of the operation being performed. The device also offers significant flexibility with its selection of five available supply voltages ranging from 1.8 to 6.0V, allowing for a wide range of uses. The AT27C4096-55PI is particularly suited for use in embedded systems due to its large memory array, random read/write capacity, flexibility with supply voltage, low power consumption and its small packaging. Embedded systems often use multiple applications that are located in different parts of the system thus making the use of a larger memory device, like the AT27C4096-55PI, quite beneficial. When it comes to writing and storing crucial information, the AT27C4096-55PI utilizes a unique method by engineering multiple write and erase cycle life cycles. Writing data is fairly straightforward and a process known as “write cycle” is used to alter the data. The write cycle is initialized by the user and the device performs a series of self-tests to ensure the data is properly written to the device. The device also offers data protection from incorrigible events such as device power loss. This is accomplished through a feature known as “block protection” or “read protect”. When this option is enabled, the device can only be read if the address is within an unlocked block range. All other areas of the device remain locked and inaccessible to user read operations. In addition to these features, the AT27C4096-55PI also offers various security options including an array of unique serial numbers and 64-bit keys which can be used to restrict user access to the device.In summary, the AT27C4096-55PI is a great memory device for those looking for a low-power, flexible, and high-density EEPROM for their embedded systems. It offers many advantages over conventional specialty memory products and provides users with the ability to quickly write and store data that is securely protected from improper access. The device’s easy-to-program features, low power consumption, and multiple serial numbers/keys make it an ideal choice for any applications requiring high capacity and reliable memory access.
