RENESAS AT25XV041B-XMHV-T

The AT25XV041B is a serial interface Flash memory device for a wide variety of high-volume consumer and connected applications. It can be operated using modern Lithium battery technologies over a wide input voltage range of 1.65V to 4.4V. It is designed for:

• systems in which program code is shadowed from Flash memory into embedded or external RAM (Code Shadow) for execution,
• where code is updated over the air,
• where small amounts of data are stored locally in the flash memory.

The erase block sizes of the AT25XV041B have been optimized to meet the needs of today's code and data storage applications. The device supports 256-byte Page erase, as well as 4-kbyte, 32-kbyte, and 64-kbyte block erase operations. By optimizing the size of the erase blocks, the memory space can be used much more efficiently. This device’s innovative design features also include: active interrupt (allowing the host to sleep during lengthy programming), erase operations (allowing the memory device to wake the MCU when completed), as well as optimized energy consumption and class-leading <200nA ultra-deep power-down modes.

The AT25XV041B is optimized for connected low-energy applications.

The device contains a specialized one-time programmable (OTP) security register that can be used for: unique device serialization, system-level Electronic Serial Number (ESN) storage, and locked key storage.

It can even be adapted with the MCU firmware to create a USE-ONCE system applicable to disposable consumables.

Specifically designed for use in a wide variety of systems, the AT25XV041B supports read, program, and erase operations. No separate voltage is required for programming and erasing.
