AT25QL641 Datasheet

Introduction

The AT25QL641 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 shadowed from Flash memory into embedded or external

RAM for execution. The flexible erase architecture of the AT25QL641 is ideal for data storage as well, eliminating

the need for additional data storage devices.

The erase block sizes of the AT25QL641 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 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.

SPI clock frequencies of up to 133 MHz are supported, allowing equivalent clock rates of 266 MHz for Dual Output

and 532 MHz for Quad Output when using the QPI and Fast Read Dual/Quad I/O commands.The AT25QL641

array is organized into 32,768 programmable pages of 256 bytes each. Up to 256 bytes can be programmed at a

time using the Page Program commands. Pages can be erased in 4 kB blocks, 32 kB blocks, 64 kB blocks, or the

entire chip.

The devices operate on a single 1.7 V to 1.95 V power supply with current consumption as low as 5 mA active and

2 µA for Deep Power-Down (DPD). All devices offered in space-saving packages. The device supports JEDEC

standard manufacturer and device identification with a 4-kbit secured OTP.

The physical block size for this device is 8 Mbit.
