The CAT25080VI-G is a memory device developed by Texas Instruments which allows for the implementation of low voltage, low power embedded and wireless applications. The device is an 8 bit, SPI based flash memory, designed to be integrated into a microcontroller, or other embedded applications. The CAT25080VI-G can be used for a variety of purposes, such as storing data, configuration information, and code. The CAT25080VI-G can operate at voltages up to 4V and temperatures between -40°C and +85°C.

The device has a range of uses, and can be found in industrial, consumer, and automotive applications. Its embedded memory makes it ideal for embedded device development, and it is also suitable for applications such as wearables, point-of-sale terminals, and instrumentation.

The device features an 8-bit serial port interface (SPI) that allows for it to be connected to a variety of host devices. The CAT25080VI-G also has a low voltage standby mode, with a current draw of 5μA. This is achieved by reducing the power consumed by the device’s logic and clock outputs. The advantage of the low standby power draw is that it reduces the current drain on the device’s battery, making it more suitable for low power applications.

The device also features a programmable three wire write protect (WPA#) signal, which can be used to protect contents of the memory from being written over or deleted. When this signal is activated, all write operations become disabled, protecting the contents of the memory from unauthorized access. The WPA# signal can also be used to trigger interrupt requests in the microcontroller, allowing for higher system level security.

The device utilizes an array of capacitor and RAM cells, which allow for it to support different types of data storage. The CAT25080VI-G can store up to 8K of data or 256 bytes of program code. Data is organized into pages, with each page corresponding to 256 bytes of data. Data can be read and written one byte at a time, or the whole block of 256 bytes can be addressed simultaneously. This makes the CAT25080VI-G suitable for applications that require bursts of data, such as in wireless communications.

The device also features a programmable page write protect (WW#) signal, which makes it possible to protect individual pages of data from being written over or deleted. When the WW# signal is enabled, the contents of the target page can be written over, but the contents of the other pages will remain unchanged. This makes the device ideal for applications where high security is required. The WW# signal can also be used to trigger a wake-up interrupt in the microcontroller, allowing the device to quickly return from sleep or standby modes.

The CAT25080VI-G is a highly useful device that can provide high levels of performance and flexibility in embedded applications. Its low power draw and wide operating temperature range make it suitable for a variety of applications, such as industrial, consumer and automotive. Its 8-bit serial port interface (SPI) makes it simple and reliable to interface the device to a variety of host devices, and its programmable WPA# and WW# signals provide additional security measures. This makes the CAT25080VI-G an ideal choice for low voltage, low power, and secure embedded applications.
