AT93C56B-MAHM-T Integrated Circuits (ICs)

Memory---AT93C56B-MAHM-T application field and working principle

The AT93C56B-MAHM-T is a low-cost memory device from the AT93C56 family of organization Non-Volatile Memory (NVM) products from Microchip Technology. The AT93C56B-MAHM-T offers 2048 bits of memory organized as five 32-bit words, with a 2-Byte station address. It is available in the 8-lead SOIC and PDIP packages, and is the ideal solution for a basic memory application.

Application Field:

The AT93C56B-MAHM-T is designed for use in a variety of applications such as factory automation, automotive and machine control, medical device applications, and other embedded applications where a basic memory requirement exists. It is ideally suited for applications where a simple non-volatile memory device with small packages for cost-effective applications is desired.

Working Principle:

The AT93C56B-MAHM-T is an NVM with a single 32-bit memory word. It is designed to access the memory though a two-byte station address. Commands from the address bus are used to control the device, such as write and read operations. The device can be read or written to as long as the memory address is provided. When a write operation is performed, data must be preceded by a write command, and only the data that is addressed by the command will be written to the memory. When a read operation is performed, data must be requested by indicating the station address. The data that is read is the data that is stored at the addressed memory location.

The AT93C56B-MAHM-T includes a write protection pin that allows the user to select a write protection level however no security feature is supported. There is also an erase switch pin which enables erasure of all memory contents. When the erase switch pin is pulled low all memory contents are written as ones and the memory is set to its unprogrammed state.

The AT93C56B-MAHM-T also comes with an external programming voltage pin which allows programming of the device under 3.0V. This feature makes it ideal for applications where low voltage programming is a requirement. The AT93C56B-MAHM-Thas a standby current of less than Icc(s) 2 mA and hence is suitable for battery powered applications that require data retention.

Conclusion:

The AT93C56B-MAHM-T is a low-cost memory device from the AT93C56 family of products and is ideally suitable for battery powered applications, factory automation, and automotive and machine control applications. It provides a basic memory device with a 32 bit word size, write protection, and a low voltage programming voltage pin. With its small package and low standby current, it is the ideal solution for all basic memory applications.
