DESCRIPTION
The IS25C01 is an electrically erasable PROM device
that uses the Serial Peripheral Interface (SPI) for
communications. The IS25C01 is 1Kbit
(128 x 8). The IS25C01 EEPROM is offered in a wide
operating voltage range of 1.8V to 5.5V to be compatible
with most application voltages. ISSI designed the
IS25C01 to be an efficient SPI EEPROM solution. The
device is packaged in 8-pin PDIP, 8-pin SOIC, and 8-pin
TSSOP.
The functional features of the IS25C01 allow it to be
among the most versatile serial non-volatile memories
available. Each device has a Chip-Select (CS) pin, and
a 3-wire interface of Serial Data In (SI), Serial Data Out
(SO), and Serial Clock (SCK). While the 3-wire interface
of the IS25C01 provides for high-speed access, a
HOLD pin allows the memories to ignore the interface in
a suspended state; later the HOLD pin re-activates
communication without re-initializing the serial sequence.
A Status Register facilitates a flexible write
protection mechanism, and a device-ready bit (RDY).
