DESCRIPTION
The IS25C16B is a 16Kbit (2048 x 8) electrically
erasable PROM devices that use the Serial Peripheral
Interface (SPI) for communications.
This EEPROM operates in a wide voltage range of 1.8V
to 5.5V to be compatible with most application voltages.
ISSI designed this device to be a practical, low-power SPI
EEPROM solution. The device is offered in lead-free, RoHS,
halogen free or Green. The available package types are
8-pin SOIC, TSSOP, UDFN and CSP.
The functional features of the IS25C16B 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 IS25C16B provides for high-speed ac-
cess, 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).
