DESCRIPTION
The IS25C08 and IS25C16 are electrically erasable
PROM devices that use the Serial Peripheral Interface
(SPI) for communications. The IS25C08 is 8Kbit
(1024x 8) and the IS25C16 is 16Kbit (2048 x 8). The
IS25C08/16 EEPROMs are offered in a wide operating
voltage range of 1.8V to 5.5V compatible with most
application voltages. ISSI designed the IS25C08/16 to
be an efficient SPI EEPROM solution. The devices are
packaged in 8-pin PDIP, 8-pin SOIC, 8-pin TSSOP, and
8-ball CSP.
The functional features of the IS25C08/16 allow them to
be among the most advanced serial non-volatile memo-
ries 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 IS25C08/16 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).
