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.

Chip Enable: CE# low activates the devices internal circuitries for
device operation. CE# high deselects the devices and switches into
standby mode to reduce the power consumption. When a device is not
selected, data will not be accepted via the serial input pin (Sl), and the
serial output pin (SO) will remain in a high impedance state.

Device Power Supply
Write Protect: A hardware program/erase protection for all or part of a
memory array. When the WP# pin is low, memory array write-protection depends
on the setting of BP2, BP1 and BP0 bits in the Status Register. When the WP# is
high, the devices are not write-protected.
Hold: Pause serial communication by the master device without resetting
the serial sequence.
