DESCRIPTION

TheIS25C128andIS25C256areelectricallyerasable

PROM devices that use the Serial Peripheral Interface

(SPI) for communications. The IS25C128 is 128Kbit

(16K x 8) and the IS25C256 is 256Kbit (32K x 8). The

IS25C128/256 EEPROMs are offered in a wide

operating voltage range of 1.8V to 5.5V for compatibility

with most application voltages. ISSI designed the

IS25C128/256 to be an efficient SPI EEPROM solution.

The devices are packaged in 8-pin JEDEC SOIC, 8-pin

EIAJ SOIC, and 8-pin PDIP.

— Partial page writes allowed

• 2.1 MHz Clock Rate (5V)

• Self timed write cycles

— 5ms max @ 2.5V

• High-reliability

— Endurance: 1,000,000 cycles per byte

— Data retention: 100 years

• 8-pin JEDEC SOIC, 8-pin EIAJ SOIC, and 8-pin PDIP

packagesavailable

• IndustrialandAutomotivetemperatureranges

• Lead-freeavailable

ThefunctionalfeaturesoftheIS25C128/256allowthem

to be among the most advanced 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

the3-wireinterfaceoftheIS25C128/256providesfor

high-speed access, a HOLD pin allows the memories to

ignore the interface in a suspended state; later the

HOLD pinre-activatescommunicationwithoutre-

initializing the serial sequence. A Status Register

facilitates a flexible write protection mechanism, and a

device-readybit(RDY).
