IS25C16

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions outside those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

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 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 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 reactivates communication without re-initializing the serial sequence. A Status Register facilitates a flexible write protection mechanism, and a device-ready bit (RDY).
