Summary TSOP-28, serial interface Flash memory, two SRAM data buffers
Description as follow:
The AT45DB081B-TU is a 2.5-volt or 2.7-volt only, serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. Its 8, 650, 752 bits of memory are organized as 4096 pages of 264 bytes each. In addition to the main memory, the AT45DB081B-TU also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprog-rammed, as well as reading or writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a selfcontained three step Read-Modify-Write operation. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a SPI serial interface to sequentially access its data. DataFlash supports SPI mode 0 and mode 3. The simple serial interface facilitates hardware layout, increases system reliability, minimizes switching noise, and reduces package size and active pin count. The device is optimized for use in many commercial and industrial applications where high density, low pin count, low voltage, and low power are essential. The device operates at clock frequencies up to 20 MHz with a typical active read current consumption of 4 mA.
