that require limited space, a low pin count, and low power consumption. The device is accessed through a 4-wire
SPI Interface consisting of a Serial Data Input (SI), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable
(CE#) pins, which can also be configured to serve as multi-I/O (see pin descriptions).
The device supports Dual and Quad I/O as well as standard, Dual Output, and Quad Output SPI. Clock frequen-
cies of up to 133MHz allow for equivalent clock rates of up to 532MHz (133MHz x 4) which equates to
66.5Mbytes/sof data throughput. The IS25xE series of Flash adds support for DTR (Double Transfer Rate) com-
mands that transfer addressesand read data on both edges of the clock.These transfer rates can outperform 16-bit
Parallel Flash memories allowing for efficient memory access to support XIP (eXecute In Place) operation.
The memory array is organized into programmable pages of 256/512bytes. This family supports page program
mode where 1 to 256/512bytes of data areprogrammed in a single command.
QPI (Quad Peripheral Interface) supports 2-cycle instruction further reducing instruction times. Pages can be erased
in groups of 4Kbyte sectors, 32Kbyte blocks, 64K/256Kbyte blocks, and/or the entire chip. The uniform sector and
block architecture allows for a high degree of flexibility so that the device can be utilized for a broad variety of appli-
cations requiring solid data retention.
MX66LM1G45G - 1G-bit Serial Flash Memory with Single and
Octal SPI
MX66LM1G45G is 1Gbit Serial NOR Flash memory, which is configured as 134,217,728 x 8 internally.
MX66LM1G45G feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire
bus while it is in single I/O mode. The three bus signals are a clock input (SCLK), a serial data input (SI), and a
serial data output (SO). Serial access to the device is enabled by CS# input.
The MX66LM1G45G MXSMIO® (Serial Multi I/O) provides sequential read operation on whole chip.
