Product Summary

The AT45DB041B-SI is a 2.5-volt or 2.7-volt only, serial interface Flash memory. It contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed, as well as reading or writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step Read-Modify-Write operation.
