Introduction

47C16-I/W16K is a kind of integrated static random access memory (SRAM) device designed primarily for use in digital systems applications. It supports synchronous as well as asynchronous bus protocol. It is offered in different packages, allowing it to occupy less space on the printed circuit board (PCB).47C16-I/W16K SRAM is mainly used for the storage of data that needs a longer time than typical dynamic random access memory (DRAM). Its known for its ability to retain data for at least 10 years without power.

Application Field

47C16-I/W16K SRAM has a wide range of applications. It is widely used in medical equipment, automation systems, scientific instruments, and communication equipment. In medical equipment, it is used for data storage, buffering, and signal processing. In automation systems, it is used for data storage, signal processing, and monitoring applications. In scientific instruments, it is used for data storage and signal processing. In communication equipment, it is used for data storage, signal processing, and encoding/decoding of digital data.

Access Time

47C16-I/W16K SRAM has an access time of 25ns. This is a measure of the time that elapses from when the device is accessed until the data is delivered. The access time decreases with an increase in the frequency of the clock, allowing the data to be delivered faster.

Voltage Range

47C16-I/W16K SRAM has an operating voltage range of 3.3V to 5V. This allows the device to be powered by a wide range of external power sources, such as batteries and AC adapters. The voltage range also allows the device to be used in a wider variety of applications.

Data Bus Width

47C16-I/W16K SRAM has a data bus width of 16 bits. This is the amount of data that can be transferred in a single operation. The wider the data bus, the more data that can be transferred in a single clock cycle.

Data Retention

47C16-I/W16K SRAM has a data retention of 10 years without power. This means that the data stored on the device will remain intact for a minimum of 10 years without electricity. This is a useful feature for devices that are used for long-term data storage, such as data loggers or medical instruments.

Working Principle

47C16-I/W16K SRAM consists of two parts: static RAM (SRAM) and external address decoder. The SRAM consists of a group of transistors that form a memory array. The memory array consists of two power planes: the source plane and the drain plane. The source plane is charged to a positive voltage, while the drain plane is charged to a negative voltage. Data is stored in the form of a binary value between these two planes.The external address decoder is a combinational logic circuit that is used to decode the binary address inputs. This allows the SRAM to store multiple data items for each address line. When an address line is input, the decoder will interpret the address and enable the associated memory array to store or retrieve data.

Conclusion

47C16-I/W16K SRAM is a versatile integrated device suitable for a wide range of applications. It has a fast access time, a wide voltage range, and a large data bus width. It is known for its long-term data retention and its ability to store multiple data items for each address line. Its ideal for applications such as medical devices, automation systems, scientific instruments, and communication equipment.
