Description
The Adesto® AT25XE512C is a highly optimized ultra-low energy serial interface Flash memory device designed for use in a wide variety of high-volume low energy consumer and industrial applications. The AT25XE512C device has been optimized by design to meet the needs of todays connected applications in the Internet of Things market space.

The granular Page Erase and Block Erase architecture allows the memory space to be used much more efficiently supporting data storage and over the air updates. Key program code subroutines and data storage segments need to reside by themselves in their own separate erase regions, and with a granular architecture the wasted and unused memory space that occurs with large sectored and large block erase flash memory devices can be greatly reduced.

The resulting improvement to software efficiency contributes to reduced CPU / MCU overheads that translate to further reduce the system energy usage levels. The device also contains a specialized OTP (One-Time Programmable) Security Register that can be used for purposes such as unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc. Specifically designed for use in many different systems, the AT25XE512C supports read, program, and erase operations with a wide supply voltage range of 1.65V to 3.6V. No separate voltage is required for programming and erasing.
