FT93C46A-ITR-B

The FT93C46A-ITR-B is a type of non-volatile memory chip that mainly serves in the automotive sector. It is produced by FTDI, a Texas-based company specializing in digital products. The chip utilizes a CMOS (Complementary Metal-Oxide Semiconductor) technology and is an 8-pin device.

This device is most commonly used to store critical information in automobiles and can hold up to 128 bits of data through the use of four address pins and one data in pin. The data can be updated without the need for physical removal with the ability to reprogram its memory in situ.

The FT93C46A-ITR-B features the two main features of any EEPROM (Electrically Erasable Programmable Read-Only Memory). One is that it can erase and reprogram its content while still retaining the data after power is out. The other is that it provides non-volatile storage, meaning that any information stored in the chip will not be erased even when power is removed.

In terms of its application fields, the FT93C46A-ITR-B is mainly used in automotive industries, but it can also be found in other industrial, medical and consumer electronics applications. It is widely used in the automotive sector for its ability to store information such as chassis and engine bills, vehicle warranty and servicing records. The chip can also be used to store user authentication information, service records, vehicle diagnostic data, and any other data that needs to be stored in a non-volatile manner.

As for its working principle, the chip utilizes an array of memory cells, each of which is composed of a transistor and a capacitor. The transistor acts as a controller, while the capacitor can hold a single bit of data. In normal operation, the cells are “read” or “write” to, based on a logic expressed in either voltage or current.

When the chip is first powered up, the cell’s capacitors are either programmed or unprogrammed depending on the data present in them. This data is stored in the capacitor and will remain unchanged until one decides to change it. In order to reprogram the chip, the voltage needs to be raised to erase the old content, and then new data is written onto the capacitor.

The FT93C46A-ITR-B is a reliable and powerful chip in the non-volatile EEPROMs sector. With its robust architecture and array of applications, it can be found in many different types of device. The chip is ideal for its stability and ability to store data even after power is removed.
