1. Description

The AT25F512B is a serial interface Flash memory device designed for use in a wide

variety of high-volume consumer based applications in which program code is shad-

owed from Flash memory into embedded or external RAM for execution. The flexible

erase architecture of the AT25F512B, with its erase granularity as small as 4 Kbytes,

makes it ideal for data storage as well, eliminating the need for additional data storage

EEPROM devices.

The erase block sizes of the AT25F512B have been optimized to meet the needs of

today's code and data storage applications. By optimizing the size of the erase blocks,

the memory space can be used much more efficiently. Because certain code modules

and data storage segments must reside by themselves in their own erase regions, the

wasted and unused memory space that occurs with large sectored and large block

erase Flash memory devices can be greatly reduced. This increased memory space

efficiency allows additional code routines and data storage segments to be added

while still maintaining the same overall device density.

The device also contains a specialized OTP (One-Time Programmable) Security Reg-

ister 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 3-volt systems, the AT25F512B supports read, pro-

gram, and erase operations with a supply voltage range of 2.7V to 3.6V. No separate

voltage is required for programming and erasing.
