NM27C256QE200

The NM27C256QE200 is a high performance CMOS 256K EPROM designed to meet the needs of microprocessor, microcontroller and data acquisition applications. It is manufactured with the Toshiba NMOS-V process and is organized as 32K x 8-bits. The NM27C256QE200 is available in a 24-pin dual-in-line plastic package (PDIP). This EPROM is fully compatible with NMOS and TTL circuits, allowing for operation up to 25MHz. All inputs and outputs are TTL-compatible and are available in two package configurations.

The NM27C256QE200 has a single address register that can store up to 13-bit data. This 13-bit address is used to access the memory. The NM27C256QE200 has two separate read and write cycles. During the read cycle, the 13-bit address is sent to the EPROM and the corresponding 8-bits data is outputted. During the write cycle, the 13-bit address is sent to the EPROM and the 8-bits data to be written is also sent to the EPROM. The 8-bit data can either be updated or erased by the write signal.

The NM27C256QE200 also feature an Advanced Address Latch (AAL) function. This feature allows a user to store the current address in an internal address latch, and then direct the read or write operations to occur at the latched address. This eliminates the need to "hardwire" the address pins in order to access the same line of data multiple times.

The NM27C256QE200 is also capable of simultaneous burst operation. During burst operation, the EPROM will read or write one line of data once and then continue to increment the internal address register and output the data from the next line of memory. In this way, the same data can be accessed multiple times without having to repeat the address inversion.

The NM27C256QE200 provides a wide range of applications in the field of embedded system design. It is the perfect memory solution for applications such as data logging, data storage, and digital signal processing. With its high performance and low power consumption, the NM27C256QE200 is ideal for use in applications that require reliable and quick data access.

In summary, the NM27C256QE200 is a high-performance EPROM that is ideal for use in embedded system applications. It is capable of both reading and writing 8-bit data, and is available in two package configurations. It also features an Advanced Address Latch (AAL) function and simultaneous burst operation, which make it perfect for data logging, data storage, and digital signal processing applications. The NM27C256QE200 is the perfect memory solution for any embedded system design.
