IS49NLC18320-25EBLI

IS49NLC18320-25EBLI is a memory component developed by Integrated Silicon Solution Inc. (ISSI). It is used as part of a general-purpose memory component that applies to a wide variety of applications and functions. This component is a low-power, high-performance integrated memory device with a low Random Access Memory (RAM) to Flash ratio.

Specifically, this memory component is a 4Mb Serial Access Memory capable of operating within the -25°C to +85°C temperature range and can perform READ, WRITE, PAGE PROGRAM and BLOCK ERASE operations. The memory component is also equipped with high-speed serial peripheral interface (SPI) and a flexible architecture, allowing for integrated memory systems.

The IS49NLC18320-25EBLI is mainly used in consumer electronics applications such as digital cameras, digital camcorders, digital video recorders, MP3 players, mobile phones and set-top boxes, due to its low cost and wide availability. Additionally, many medical devices and automotive systems also use this component.

In order to use this component, it is necessary to have an external power source of +2.7V to +3.6V and an Interface operating between 1MHz and 33MHz. It also requires extra power for the data retention mode and deep power down mode.

The IS49NLC18320-25EBLI is a two-wire serial interface for data communication and instruction sequence control. The interface consists of a Clock (CLK) signal, a Data Input/Output (DI/DO) signal, a CHIP ENable (CE#) signal and a Write (WP#) signal. All signals are driven by the controller.

The Clock signal is used to synchronize data transfers between the controller and the memory component. All instruction commands and data must be transferred on the DI/DO signal. The CHIP ENable signal is used to enable and disable the component. The Write signal is used to control Write Enable and Write Disable operations.

The memory component can be operated in either the READ or WRITE mode. In READ mode, data can be transferred from the component to the controller. The component is also capable of performing various write operations including PAGE PROGRAM, BLOCK ERASE and PAGE READ mode (for erasing data).

In addition, the component can be put into HOLD mode, where the component can freeze its operation while the controller is changing its receive or transmit data. The component can also be put into Extensive Deep Power Down mode, where it can be completely shut down in order to preserve power when the component is not in use.

Overall, the IS49NLC18320-25EBLI is a reliable, low-power and high-performance memory component that can be used for a wide variety of consumer electronics, medical and automotive applications. With its flexible architecture and wide temperature range, the component can be used for a variety of applications with ease.
