GENERAL DESCRIPTION
The IS25LD256C 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 2.7 Volt to 3.6 Volt, to perform read, erase and program operations. The devices can be programmed in standard EPROM programmers.
