Introduction

NMC27C16BQ200 is a combination memory and logic device which is developed by New Media Corporation (NMC) in order to offer excellent and high performance. This device combines 16K words of memory and logic functions into a single chip. It consists of 32 16Kx1 DRAMs. It is equipped with an integrated address multiplexer, which directly multiplexes the address signals. It is commonly used in a wide range of systems, especially in embedded computer applications.

Features

NMC27C16BQ200 has several key features that make it an ideal choice for embedded applications. Most overtly, it has a very low power consumption of 0.6 W as well as a high speed access time of 20 ns. It also has a built-in write protect capability and it is able to support multiple data transfers without the need for extra chip select signals. Furthermore, this device has a very small Size Date Code, (SDC) which is often an important factor in the design of embedding circuits.

Application Field

NMC27C16BQ200 is used in a wide variety of embedded applications. It can be used in communication systems, industrial automation system, medical and medical imaging systems, and automotive applications. Communication systems use NMC27C16BQ200 for various RAM based memory applications. It is also used in medical systems, where it can be used to store medical images and other medical-related data. This device is also used in industrial automation systems to store various control and calculation data. In addition, it is used in automotive electronics to store audio, video, and navigation-related data.

Working Principle

NMC27C16BQ200 is based on DRAM technology. DRAM stands for Dynamic Random Access Memory. It is a type of memory where the information is stored be written and erased on each access. Unlike other types of memory, a refresh signal must be sent to DRAM to keep the stored data.While most DRAMs require external address-multiplexers and separate device select signals, NMC27C16BQ200 has an embedded address-multiplexer which simplifies the assembly of the circuit by eliminating external components. The system also offers a built-in write protect capability, which allows a single chip select signal to be used to protect the memory from accidental writes.When a read or write cycle is requested, the address-multiplexer and write-protect mechanism send control signals to the DRAM. The DRAM will then access or store the data as instructed. The data is then sent through the a- Multiplexer and transmitted back to the CPU or other device requesting it.

Conclusion

NMC27C16BQ200 is an excellent memory and logic device developed by New Media Corporation. Its high performance, low power consumption, and integrated address-multiplexer make it an ideal choice for embedded applications. It is widely used in communication systems, industrial automation, medical and automotive applications. Its working principle is based on DRAM technology, where refresh signals are needed to keep the stored data.
