Description
www.DataSheet4U.com
The AT25FS010 provides 1,048,576 bits of serial reprogrammable Flash memory
organized as 131,072 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operation
are essential. The AT25FS010 is available in a space-saving 8-lead JEDEC SOIC and
8-lead Ultra Thin SAP packages.

High Speed Small Sectored SPI Flash Memory

The AT25FS010 is enabled through the Chip Select pin (CS) and accessed via a 3-wire
interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock
(SCK). All write cycles are completely self-timed.
BLOCK WRITE protection for upper 1/32, 1/16, 1/8, 1/4, 1/2 or the entire memory array
is enabled by programming the status register. Separate write enable and write disable
instructions are provided for additional data protection. Hardware data protection is pro-
vided via the WP pin to protect against inadvertent write attempts to the status register.
The HOLD pin may be used to suspend any serial communication without resetting the
serial sequence.
Absolute Maximum Ratings*
Operating Temperature....................................–40°C to +85°C
Storage Temperature .....................................–65°C to +150°C
Voltage on Any Pin
with Respect to Ground .................................... –1.0V to +5.0V
Maximum Operating Voltage ............................................ 4.2V

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
