Atmel AT45DB081D
address lines and a parallel interface, the Atmel
interface to sequentially access its data. The simple sequential access dramatically reduces
active pin count, facilitates hardware layout, increases system reliability, minimizes switching
noise, and reduces package size. 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.
To allow for simple in-system reprogrammability, the Atmel AT45DB081D does not require high
input voltages for programming. The device operates from a single power supply, 2.5V to 3.6V
or 2.7V to 3.6V, for both the program and read operations. The AT45DB081D 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 and erase cycles are self-timed.
