GENERAL DESCRIPTION
The IS25LQ020/040 is 2 Mbit / 4 Mbit Serial Peripheral Interface
(SPI) Flash memories, providing single-, dual or quad-output. The
devices are designed to support a 33 MHz fclock rate in normal read
mode, and 104 MHz in fast read (Quad output is 100MHz), the fastest
in the industry. The devices use a single low voltage power supply,
ranging from 2.3 Volt to 3.6 Volt, to perform read, erase and
program operations. The devices can be programmed in standard EPROM
programmers.
