FEATURES

DESCRIPTION

TheIS25C32AandIS25C64Aareelectricallyerasable

PROM devices that use the Serial Peripheral Interface

(SPI) for communications. The IS25C32A is 32Kbit

(4096 x 8) and the IS25C64A is 64Kbit (8192 x 8). The

IS25C32A/64A EEPROMs are offered in a wide

• SerialPeripheralInterface(SPI)Compatible

— Supports SPI Modes 0 (0,0) and 3 (1,1)

• Wide-voltageOperation

— Vcc = 1.8V to 5.5V

• LowpowerCMOS

operating voltage range of 1.8V to 5.5V to be compatible

with most application voltages. ISSI designed the

IS25C32A/64A to be an efficient SPI EEPROM solution.

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

and 8-pin TSSOP.

— Active current less than 3.0 mA (2.5V)

— Standby current less than 2.0 µA (2.5V)

• Block Write Protection

— Protect 1/4, 1/2, or Entire Array

• 32 byte page write mode

— Partial page writes allowed

• 10 MHz Clock Rate (5V)

• Self timed write cycles (5 ms Typical)

• High-reliability

— Endurance: 1 million cycles per byte

— Data retention: 100 years

• IndustrialandAutomotivetemperatureranges

• 8-pin PDIP, 8-pin SOIC, and 8-pin TSSOP Packages

ThefunctionalfeaturesoftheIS25C32A/64Aallowthem

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-wireinterfaceoftheIS25C32A/64Aprovidesfor

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

ignore the interface in a suspended state; later the

initializing the serial sequence. A Status Register
