FT93C46A-UTR-T Integrated Circuits (ICs)

Memory

FT93C46A-UTR-T is a kind of non-volatile serial EEPROM from Microchip Technology Inc. It is a chip with the parallel address bus and three-wire serial I/O control. This EEPROM employs the 9346 Series Technology, with 1Kbits (128 x 8) of read/write memory organized in 2 separately protected blocks of 64 bytes each. Through re-programming, FT93C46A-UTR-T is also used for system non-volatility. It is widely used in many applications including information recording, data management, security control, identification, device configuration and so on.

Application Field

The FT93C46A-UTR-T is a popular non-volatile serial EEPROM device which offers an excellent combination of features and benefits. It is widely used in contactless card applications such as loyalty cards, prepaid cards, network cards, medical cards, etc. It is ideal for zero insertion force (ZIF) applications as well, such as cellular phones, PDAs, toys, and portable devices. Besides, its low cost, modest total system power consumption, and compatibility with low-cost PC systems also make it ideal for many automotive, medical, networking, and consumer applications. Apart from these applications, FT93C46A-UTR-T can also be used in industrial application and energy, transportation and communication applications.

Working Principle

The FT93C46A-UTR-T consists of 128 8-bit registers that store 8-bit words. Data can be read from, or written to, each register. It can be read directly or via a serial shift register. To read data serially, the chip first shifts out of the addressed register the desired bytes, beginning with the least significant one. After all the shifted data is sent, the chip then sends a start bit followed by 8 bits of the next data byte. Data will be shifted out of the chip until the Sequential Read/Write Mode is terminated by sending a Stop-Bit. To write data serially, the chip must first receive an 8-bit command from the host controller and before the actual data is to be written. Here are the three main programming operations that can be applied to the FT93C46A-UTR-T: Write Word (or Byte), Sequential Read/Write and Chip Erase.

Advantage

The FT93C46A-UTR-T is a low cost, low power non-volatile memory device with a very attractive combination of features. Its programmable read only memory (PROM) matrix makes it suitable for many automated applications. Its small size allows for it to be placed in small and narrow spaces. It has an ultra-low current consumption of less than 10 μA for 1 Kb, and it has built-in programmable memory protection which makes it very secure. In addition, the FT93C46A-UTR-T also has programmable hardware reset, two hardware selectable memory banks, and low power static design. All these features make it an ideal choice for many applications.

Conclusion

The FT93C46A-UTR-T is a popular and versatile non-volatile serial EEPROM device, it is widely used in a variety of contactless card, zero insertion force (ZIF), automotive, medical, networking, consumer applications and other industrial, energy, transportation and communication applications. It is small in size, low cost and has excellent combination of features, such as low power consumption, programmable read only memory (PROM) matrix and programmable memory protection which offer high security. All these features make the FT93C46A-UTR-T an ideal choice for many applications.
