11AA080T-I/MS

11AA080T-I/MS is a memory device from FreeScale Semiconductor. It is 8-pin chip, about 200 mils in height, and it has an operating temperature range from -40℃ to 85℃. It is from FreeScale\'s Low-Density Flash family. 11AA080T-I/MS stands for 8k Nonvolatile SRAM, meaning that it provides 8Kbit of non-volatile memory capacity.

The main application of the 11AA080T-I/MS is to provide a non-volatile memory data backup solution. It can be used in situations where a system needs to store data even when there is no power. It is especially useful in embedded systems, such as automotive, industrial control and medical applications, where limited power or no power sources are available.

In terms of working principle, the 11AA080T-I/MS features a cell array and control logic circuit. The cell array consists of nonvolatile storage cells that store data even when power is removed. When power is applied to the chip, the cell array is loaded into an SRAM (Static Random Access Memory) holding register. The SRAM holding register is used to buffer data and provide quick access to it.

The control logic provides the functions of self-timed write operations and read operations that include a read-while-write mode. The control logic also has a power-on reset capability that ensures that the chip starts with a known state each time power is applied. Additionally, the 11AA080T-I/MS has an ECC (Error Correction Code) feature, which provides extra security and reliability against data loss.

In conclusion, the 11AA080T-I/MS is a low-density non-volatile memory device from FreeScale Semiconductor. It provides 8Kbit of non-volatile memory capacity and features cell array, control logic, ECC and power-on reset capabilities, making it a great data backup solution for embedded systems in scenarios where limited/no power are available.
