IS25WQ040-JNLE-TR

IS25WQ040-JNLE-TR is a small-package serial flash memory device used for a wide range of applications. It is a single memory device that provides an ideal solution for embedded system designers needing simple off-the-shelf, low-cost flash memory applications. This device features low power consumption and a wide operating temperature range for improved system reliability.

The IS25WQ040-JNLE-TR is primarily used in industrial and automotive applications as nonvolatile memory. It is ideal for storage of product code, calibration, and system configuration information, as well as monitoring programs or software updates. It is also used in higher performance automotive applications such as product code storage, where the low power consumption can provide improved system reliability over the life cycle. Industrial applications include MCU-based controllers where software updates or product code storage are required.

The IS25WQ040-JNLE-TR memory device is based on standard serial peripheral interface (SPI) protocol. It utilizes a common three-wire, full-duplex, synchronous serial interface for communication and control operations. The device is designed to facilitate easy integration by operating off a single 3.3V power supply. It is also compatible with both 3.3V and 5V logic interfaces, allowing for a wide range of compatibility with other system components.

The IS25WQ040-JNLE-TR memory device includes a 8K-byte sector, as well as four 4K-byte blocks, 64-byte pages, and 32-byte sub-pages. This provides increased storage capacity and allows for greater flexibility when programming and accessing the user data. The sector and blocks can be programmed and erased in the standard SPI protocol without the need for an erase command. This ensures fast and easy access to memory data.

The IS25WQ040-JNLE-TR provides protection against accidental program and erase operations. A write-protect pin (WP#) is used to protect the entire device from program and erase operations, while individual write-protection bits can be set for each sector or block to enable or disable write protection for certain areas.

The IS25WQ040-JNLE-TR memory device also includes several security features that can be used to protect data. These include the optional OTP Lock, the EZ-Write function, and the NDS Lock function. The OTP lock prevents any unauthorized program or erase operations, while the EZ-Write function allows users to easily write data to a protected sector or block without the need for an erase command.

In summary, the IS25WQ040-JNLE-TR is a low-power, small-package serial flash memory device that is ideal for a wide range of industrial and automotive applications. It features a wide operating temperature range, a low power consumption rating, and a variety of security features for enhanced data protection. It is designed to facilitate easy integration with other system components and its SPI interface allows for fast and reliable data access.
