Quick Detail:
4-megabit 2.5-volt or 2.7-volt DataFlash
Description:
The AT45DB041D is a 2.5V or 2.7V, serial-interface Flash memory
ideally suited for a wide variety of digital voice-, image-,
program code- and data-storage applications.
The AT45DB041D supports RapidS serial interface for applications
requiring very high speed operations. RapidS serial interface is
SPI compatible for frequencies up to 66 MHz. Its 4,325,376 bits of
memory are organized as 2,048 pages of 256 bytes or 264 bytes each.
In addition to the main memory, the AT45DB041D also contains two
SRAM buffers of 256/264 bytes each. The buffers allow the receiving
of data while a page in the main Memory is being reprogrammed, as
well as writing a continuous data stream. EEPROM emulation (bit or
byte alterability) is easily handled with a self-contained three
step read-modify-write operation. Unlike conventional Flash
memories that are accessed randomly with multiple address lines and
a parallel interface, the DataFlash uses a RapidS serial 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 AT45DB041D
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 AT45DB041D 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).
