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 appli-
cations where high-density, low-pin count, low-voltage and low-power are essential.
To allow for simple in-system reprogrammability, the AT45DB321D does not require high input
voltages for programming. The device operates from a single power supply, 2.7V to 3.6V, for
both the program and read operations. The AT45DB321D 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.
