• Manufacturer Part Number: SA25F005
• Description: 512Kb Serial Flash
• Manufacturer: Saifun

The SA25F005 is a 512Kb (256K X 2)
CMOS non-volatile serial Flash Memory.
This device fully conforms to the SPI 4-wire
protocol, is enabled through the Chip Select
(CSb) pin, and uses Clock (SCK), Data-in
(SI)
synchronously
between the SPI microcontroller and the
Serial FLASH memory.
The memory can be programmed from 1 up
to 256 bytes at a time via the Page
Program (PP) instruction.
The memory is organized into two sectors.
Each sector contains 128 pages, with each
page being 256 bytes wide. The entire
memory can therefore be viewed as
consisting of 256 pages, or 65,536 bytes.
The memory can be erased in one of the
following ways:
Each device requires only a 3.0V power
supply (2.7 V to 3.6 V) for both read and
write functions. Internally generated and
regulated voltages are provided for the
program
SA25F005 does not require a V

The SA25F005 is part of the SPI Flash and
EEPROM family. It is designed to work with
any
microcontroller, and offers both hardware
(WPb pin) and Software (“block protect”)
data protection. For example, programming
a 2-bit code into the status register prevents
program with top ¼, top ½ or entire array
write protection and enables block write
protection. Separate program enable and
program disable instructions are provided
for additional data protection. Hardware
data protection is provided via the WPb pin
to protect against inadvertent write attempts
to the status register.
Saifun’s SPI Serial Flash products are
designed
requiring high endurance and low power
consumption for a continuously reliable
non-volatile solution for all markets.
