One of the most essential components in the embedded systems is Memory, used to store various data. 93C56CT-I/MC is a popular device in this field, with its application field and working principle being broadly explored. This article will detail its application field and working principle.

The 93C56CT-I/MC is a 512-bit EEPROM securely stored device that comes in eight-pin PDIP (plastic dual-in-line package) packages. This device is especially useful for non-volatile memory storage of data, such as with settings information for electronic products, or for storing and retrieving binary data inputs for devices such as motor drives.

It is ideal for applications that require frequent data updates, or write access. The device utilizes a 3-wire serial bus protocol for communication and has an address latch allowing up to eight input/output (I/O) connections. The device also has two control pins, including a reset pin and a write protect pin, which can be used to customize user access.

The 93C56CT-I/MC device is quite easy to use, since all of its features are easy to configure and its comprehensive documentation allows even novice users to be able to program it without much difficulty. Furthermore, its reliability, stability and durability makes it a preferred choice for engineers for tasks such as password authentication, data storage, etc.

Now let us look at its working principle. The 93C56CT-I/MC employs two-wire or three-wire serial communication protocols, the two-wire protocol being the simpler one. The two-wire protocol is used to program the device and is initiated by the transmission of a Start Bit (S), followed by six hex address bits (AABBCCDD), four sector code bits (r0r1r2r3), and an end bit (E).

The device is then activated, and the data can be shifted out and received using this two-wire protocol. The transmission of data is clocked in and out using the Clock pulse, while data is transferred in and out synchronously using the Data bit. The device is programmed by supplying the required data along with the start, address and sector bits and the write enable signal. All programming is done in this way until the last four bit data is programmed with which the write enable signal is set to ‘0’ to finish the programming session.

The three-wire protocol consists of the same data information and address bits as mentioned above, but with the addition of a reset pin, which is used to reset the device. The device is programmed in the same way as the two-wire protocol and then reset. This resets the device and it can be used for storage purposes.

The 93C56CT-I/MC is ideal for embedded applications, thanks to its small size, low power requirements and wide temperature range (-40°C to +85°C). It is also relatively inexpensive, making it an attractive choice for engineers. These features, combined with the device’s robust programming capabilities, stability and durability have made the 93C56CT-I/MC a popular choice in the field of Memory.
