Features
- Universally compatible pinout and command set
- Standard block architecture
- Supports Dual I/O, Quad I/O operation
Description
The AT25SF641 is a member of our standard class code and data storage solutions designed for 3V systems in which program code is shadowed from Flash memory into embedded or external RAM for execution.
The architecture includes erase block sizes that are optimized to meet the needs of today's code and data storage applications and three security register pages for unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc.

AT25SF641B-SHB-T chip erase timing
I am currently evaluating the AT25SF641B-SHB-T device as replacement for other SPI flash device. I found that timing for chip erase operation (command 0xC7) is much much faster than specified by datasheet ( DS-AT25SF641B-191D-122020.pdf ) The datasheet states on page 51 a typical chip erase time ...

AT25SF641B: Flash Read always returning 0xFF
Hello, The AT25SF641B device I am having issues with is interfaced with a TMS320F28379D. Please see C code below. The code performs the flash operations as defined in the Operations[] array every 10ms (FlashTestStateMachine_Task() is called every 10ms. This is verified by noticing u16FlashEraseCounter counts up to 2999 during ...
