AT45DB011 General Description


The AT45DB011 is a 2.7-volt only, serial interface Flash memory suitable for in-sys-tem reprogramming. Its 1,081,344 bits of memory are organized as 512 pages of 264 bytes each. In addition to the main memory, the AT45DB011 also contains one SRAM data buffer of 264 bytes. Unlike conventional Flash memories that are accessed ran-domly with multiple address lines and a parallel interface, the DataFlash uses a serial interface to sequentially access its data. The simple serial interface facilitates hard-ware layout, increases system reliability, minimizes switch-ing 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. Typical applica-tions for the DataFlash are digital voice storage, image storage, and data storage. The device operates at clock frequencies up to 13 MHz with a typical active read current consumption of 4 mA.

To allow for simple in-system reprogrammability, the AT45DB011 does not require high input voltages for pro-gramming. The device operates from a single power sup- ply, 2.7V to 3.6V, for both the program and read operations. The AT45DB011 is enabled through the chip select pin (CS) and accessed via a three-wire interface consisting of the Serial Input (SI), Serial Output (SO), and the Serial Clock (SCK).

All programming cycles are self-timed, and no separate erase cycle is required before programming.
