data buffers of 528 bytes each. The buffers allow receiving
of data while a page in the main memory is being repro-
grammed. Unlike conventional Flash memories that are
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
supply, 4.5V to 5.5V, for both the program and read opera-
tions. 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
Architecture Diagram illustrates the breakdown of each
level and details the number of pages per sector and block.
All program operations to the DataFlash occur on a page
by page basis; however, the optional erase operations can
be performed at the block or page level.
