accessed randomly with multiple address lines and a paral-
lel interface, the DataFlash uses a serial interface to
sequentially access its data. 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.
Typical applications for the DataFlash are digital voice stor-
age, image storage, and data storage. The device operates
at clock frequencies up to 15 MHz with a typical active read
current consumption of 15 mA.
To allow for simple in-system reprogrammability, the
AT45D161 does not require high input voltages for pro-
gramming. The device operates from a single power sup-
ply, 4.5V to 5.5V, for both the program and read
operations. The AT45D161 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.
Block Diagram
Memory Array
To provide optimal flexibility, the memory array of the
AT45D161 is divided into three levels of granularity com-
prising of sectors, blocks, and pages. The Memory Archi-
tecture Diagram illustrates the breakdown of each level and
details the number of pages per sector and block. All pro-
gram operations to the DataFlash occur on a page by page
basis; however, the optional erase operations can be per-
formed at the block or page level.
