AS7C34096A-12JCN, a type of memory, is widely used in multiple applications, such as embedded systems, gaming systems, on-chip caches, and communications systems. This part integrates 1 Meg x 4-bit CMOS static RAM with an asynchronous address and data port. It is a low-power, low-voltage device that operates from a 2.7 to 2.9 V supply voltage with both active and standby modes.

The chief feature of this product is its fast access time, which stands at 15 ns maximum. The AS7C34096A-12JCN also has automatic power-down features that allow for very low-power operation in idle or inactive states. Additionally, these parts are available in a 16-pin SOIC package, providing a smaller form-factor.

The working principle of the AS7C34096A-12JCN is that it works like a dynamic random access memory. DRAMs are essentially capacitors that are charged or discharged in order to store data. With the AS7C34096A-12JCN, a capacitor is charged by applying a small voltage pulse that causes the capacitor to store a 1 or a 0, and then the capacitor is discharged with a small voltage pulse that causes it to store a 0 or 1. This process is repeated for each bit in the memory.

The AS7C34096A-12JCN also uses multiplexing for the address signals. The chip has two address pins, one for the address, and one for the row. When a voltage is applied to the address line, the multiplexer determines which of the two address pins is being used, and then the multiplexer connects it to the chip so that the proper row can be accessed.

In terms of its application field, the AS7C34096A-12JCN is classified as a SRAM, or Static Random Access Memory, as opposed to its DRAM (Dynamic Random Access Memory) counterpart. SRAMs are typically used in embedded systems, gaming systems, on-chip caches, and communications systems, due to their faster access time, smaller size, low power consumption, and lack of need for refreshing. Here, the AS7C34096A-12JCN can be used to store program settings, cache data, or even as a frame buffer for graphics.

In summary, the AS7C34096A-12JCN is a memory device with an asynchronous address and data port, integrated 1 Meg x 4-bit CMOS static RAM, low-power and low-voltage operation from 2.7 to 2.9 volts, 15 ns maximum access time, 16-pin SOIC package, DRAM-like working principle, and applications in embedded systems, gaming systems, on-chip caches, and communications systems.
