GENERAL DESCRIPTION
The IS25CD025 are 256Kbit Serial Peripheral Interface (SPI) Flash memories, providing single- or dual-output.
The devices are designed to support a 33 MHz clock rate in normal read mode, and 100 MHz in fast read, the
fastest in the industry. The devices use a single low voltage power supply, wide operating voltage ranging from
2.70 Volt to 3.60 Volt, to perform read, erase and program operations. The devices can be programmed in
standard EPROM programmers.
The IS25CD025 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output (SlO), Serial
Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. They comply with all recognized command
codes and operations. The dual-output fast read operation provides and effective serial data rate of 200MHz.
The devices support page program mode, where 1 to 256 bytes data can be programmed into the memory in
one program operation. These devices are divided into uniform 4 KByte sectors or uniform 32 KByte blocks.
The IS25CD025 are manufactured on pFLASH™’s advanced non-volatile technology. The devices are offered
in 8-pin SOIC 150mil and 8-pin TSSOP. The devices operate at wide temperatures between -40°C to +105°C.

SYSTEM CONFIGURATION
The IS25CD025 devices are designed to interface directly with the synchronous Serial Peripheral Interface (SPI)
of the Motorola MC68HCxx series of microcontrollers or any SPI interface-equipped system controllers. The
devices have two superset features that can be enabled through specific software instructions and the
