operation. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a
parallel interface, the Atmel
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 AT45DB161D 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 AT45DB161D 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.
