The AS6C6264-55STCNTR belongs to the family of SRAM, or Static Random Access Memory. It is an 8-bit parallel interface device which provides 2,097,152 bits of high-speed, low-power memory. It is widely used in consumer electronics, medical equipment, industrial control, and automotive applications. This article will discuss the application field and working principle for the AS6C6264-55STCNTR.

Application Field

The AS6C6264-55STCNTR provides an ideal solution for consumer electronics, industrial control, automotive and medical equipment applications. It offers an excellent choice for fast page mode burst operations, and is a preferred choice for those applications that require lower power consumption. The device is offered in two different packages, to accommodate different board configurations and space requirements, and is available in both commercial and industrial temperature ranges. Furthermore, the device offers a wide supply voltage range of 1.7V - 3.6V, allowing it to be used in low power applications.

In consumer electronics applications such as mobile phones, PDAs, digital cameras, MP3 players and other portable electronic devices, the AS6C6264-55STCNTR provides the necessary performance and power consumption requirements needed. In industrial control applications such as programmable logic controllers, point-of-sale terminals, industrial robots and other automated equipment, the AS6C6264-55STCNTR provides high levels of reliability. In automotive applications such as engine management systems, navigation systems, instrument clusters and communication systems, the AS6C6264-55STCNTR provides an excellent, low-power memory solution. In medical equipment applications such as surgical equipment and imaging equipment, the AS6C6264-55STCNTR offers excellent operation and durability. Speed, density and power consumption are all important considerations in these types of applications.

Working Principle

The AS6C6264-55STCNTR utilizes a serial configuration for the address and data lines. All data and address transfers are synchronous, and a single write is required for both. The device is organized into 16 sub-blocks of 8K x 8 bit words. Each sub-block has its own chip-select and power-down control lines. Data transfer rates are programmable from 6 MHz to 33 MHz and data can be written in either 8-,16-, or 32-bit bursts.

The AS6C6264-55STCNTR utilizes an internally generated address control signal, referred to as the Data Enable (DE) signal. This signal is generated when the first address location is accessed. The DE signal is used to control the flow of data through the device, and is used in conjunction with the Chip Enable (CE) signal to indicate whether or not data is present. The device also utilizes an internal status register which allows the user to monitor whether or not data is present, as well as providing control for system operations.

The AS6C6264-55STCNTR provides for a read-modify-write cycle, in which data can be read from a location, modified, and then written back to the same location. This cycle allows for a more efficient data access and storage process. In order to facilitate the read-modify-write cycle, the device also provides for a write latch signal (WE#). This signal controls the writing of data back to the memory.

The AS6C6264-55STCNTR provides an 8-bit parallel interface between external systems and the memory. A write strobe (WE#) signal is used to signal writes to the device, while a chip-select (CE#) signal is used to signal reads from the device. Data and address is transferred through the device in synchronous burst transfers, allowing for multiple-byte writes and reads.

In summary, the AS6C6264-55STCNTR is an excellent choice for SRAM applications. It provides an 8-bit bus interface and offers an excellent memory solution for a wide range of applications. The device has a large memory capacity of 2,097,152 bits, and is capable of fast page mode burst operations. This, combined with its low power consumption and small packages, makes it an ideal choice for many applications in consumer electronics, industrial control, automotive and medical equipment.
