The 47L04-I/ST is an integrated device used in memory applications. It is a 4-K non-volatile SRAM with an I block (active-high) and an ST block (active-low) with an embedded controller. It is a low-power device that is generally used in battery-operated systems with its wide temperature range and low standby current.

The 47L04-I/ST is suitable for applications in a broad range of industries, including automotive, industrial, aerospace, medical, and marine/military. It is most commonly used for data logging, data acquisition and data storage applications. It can also be used in other embedded applications such as industrial control, machine automation, and environmental monitoring.

The 47L04-I/ST is composed of two main blocks; the Input/Output (I/O) block, which handles the external interface, and the Non-Volatile memory (NVM) block, which contains the electrical and digital logic for data storage, pipeline registers and control logic. The NVM block is composed of a 4K word x 8-bit SRAM and an embedded controller with the ability to detect and control power transitions ( either power up or down) of the device. The controller also handles read and write operations.

The 47L04-I/ST features a built-in hardware read-write protection system which activates the device\'s write-protect pin when it senses a valid read or write signal. This allows the 47L04-I/ST to maintain data in the SRAM without being disturbed or modified when the power is shut down or when the device is taken out of power mode. The device also features flexible write protect and sector protection capabilities, allowing the user to protect specific areas of the memory from write access.

The working principle of the 47L04-I/ST is fairly simple. When data is written to the SRAM, the embedded controller detects the write signal and activates the write-protect signal. This prevents the entire memory from being modified or erased, allowing the user to store data safely. When data is read, the embedded controller detects the read signal and then passes it to the NVM block. The data is then transferred to the I/O block, and then to the external interface. The 47L04-I/ST can also be set into a power-saving mode, where the device enters a low power state and consumes only a fraction of its full active power.

The 47L04-I/ST is a versatile and reliable solution for memory applications. Its low power consumption and wide temperature range make it suitable for a broad range of applications. Furthermore, its built-in hardware read-write protection system ensures that data is safe and secure. All in all, the 47L04-I/ST offers an ideal memory solution for embedded applications.
